DETAILED DESCRIPTION OF THE INVENTION 19
[019] The present technology, in general, relates to sulfo-estolides. More particularly, the present technology relates to sulfo-estolide derivatives and salts of sulfo-estoϋdes, their methods of manufacture and the various applications and/or processes of utilizing them. For example, the present technology relates to magnesium ion containing formulations of suifo-estolides, sulfo-estolide derivatives and salts of suifo-estoiides used in heavy duty liquid (HDL) laundry detergents.
[020] The compositions described here include, but are not limited to. sulfo- estolides having the following general Formula 1 :
Figure imgf000013_0001
[021 ] In general Formula 1 : n is an integer from about 1 to about 30, alternatively about 1 to about 10, alternatively 1 to 4, alternatively 1. 2, or 3, alternatively 1 or 2, alternatively 1 ; or mixtures thereof; One of X and Y is SO3 Z, the other of X and Y is H (i.e., hydrogen), and X and Y are independently assigned in each repeating unit; A1 and A2 are independently selected linear or branched, saturated or unsaturated, substituted or unsubstituted alkyi diradicals, where the total number of carbons for each repeating unit is independent and in the range of Cs to C22 As defined here, the term "alkyi diradical" is meant to refer to a linking hydrocarbon or alkylene segment, for example but by no means limited to -(CH2)S -, - (CH2)4 ~, -(CH2)S -. and so forth; a is 0, 1 . or 2, and is independently assigned in each repeating unit. When a = 0, 1 , or 2, the functional group corresponds to an alpha- sulfo-estoiide. beta-suifo-estoiide, or gamma-sulfo-estolide, respectively; R can be linear or branched, saturated or unsaturated, substituted or unsubstituted hydrocarbon, wherein the total number of carbon atoms can be from 1 to about 24. In at least one embodiment, R has from about 7 to about 21 carbon atoms, alternatively from about 8 to about 16 carbon atoms, and can be a saturated or unsaturated linear or branched hydrocarbon, a linear or branched hydroxyalkane 1 *3 sulfonate, or a linear or branched aikene sulfonate. For example, in one embodiment, A1 and A2 are linear alkyl diradicals and R is saturated or unsaturated linear hydrocarbon, linear hydroxyalkane sulfonate, or linear aikene sulfonate having from about 7 to about 21 , alternatively from about 8 to about 18 carbons; W is a monovalent or divalent metal; ammonium; substituted ammonium; H; or a linear or branched, substituted or unsubstituted alkyl having from 1 to about 22 carbon atoms. For example, W can be an alkali or alkaline earth metal cation. Alternatively, VV can be a glycerine joined by an ester linkage, e.g., a substituted C3 alkyl such that general Formula 1 is incorporated one or more times as an ester in a monoglyceride, a diglyceride, or a triglyceride; and Z is H or a monovalent or divalent metal cation, ammonium or substituted ammonium cation, preferably an alkali or alkaline earth metal cation, for example potassium, sodium, calcium, or magnesium, with potassium being preferred in certain embodiments. For example, it has been observed unexpectedly that at least in some embodiments, a heavy duty liquid laundry concentrate of the present technology containing a potassium salt is significantly lower in viscosity than a comparable composition that contains the same amount of a sodium salt.
[022] The above structure is illustrative of the sulfo-estolide products that may be derived from, for example, linear unsaturated fatty acid feedstocks. It is understood that sultone hydrolyzed products and structures of a comparable nature may be derived from branched and/or substituted unsaturated fatty acids or mixtures of linear and branched and/or substituted unsaturated fatty acids.
[023] Additional sulfo-estolide compositions may be produced from fatty acid feedstocks comprising polyunsaturated fatty acids, where A1 and A2 may be independently selected from the set of alkyl diradicals that can be: a) saturated; b) unsaturated, c) unsaturated and substituted with a sulfonate group, d) substituted with a hydroxyl group and a sulfonate group; or e) substituted with a ester group and a sulfonate group (i.e., a sulfo-estolide).
[024] In another embodiment of the present technology, the sulfo-estolide compositions are comprised of carboxylic esters, or are reported in an ester analysis as carboxylic esters. Although it is contemplated that at least some of these carboxylic esters are sulfo-estolides, the presently described technology is not limited by the accuracy of this belief, for example the compositions may contain carboxylic esters wherein X and Y within one or more repeating units, in genera! Formula 1 , are both H.
[025] Sn another embodiment of the present technology, the sulfo-estolide compositions can be comprised of a sulfo-estolide of general Formula 1 and a non~ sulfonated estolide which comprises two or more fatty acid chains that does not contain a sulfonate group.
[028] Further information regarding sulfo-estoiides, sulfo-estolide derivatives, and salts of sulfo-estolides is presented in United Slates Application Serial No. 12/353.751 , filed January 14, 2009, which is hereby incorporated by reference.
Definitions
[027] The term "sulfo-estolide" ("SE") is used here to further describe general
Formula 1. The term "partially hydrolyzed sulfo-estolide" ("PHSE") describes compositions of general Formula 1 wherein the esters have been partially hydrolyzed between (about 1 % to about 95%). The term ''hydrolyzed sulfo-estolide" ("HSE") describes compositions of general Formula 1 wherein the esters have been fully hydrolyzed (> than about 95%).
[028] The term "sultone hydrolyzed product" ("SHP") is used here to describe salts of sulfo-estolides that are produced from feedstock comprising unsaturated fatty acids by a process comprising the steps of suifonation with SOs, neutralization, and hydrolysis of suilones. The neutralization and hydrolysis are conducted at a level of caustic addition that maintains the pH in the range from about 4 to about 10
[029] The resulting SHP product contains carboxylic acid esters at a level that corresponds to about 5 to about 95 mol%, alternatively about 20 to about 80 mo!%, alternatively about 20 to about 45 moi%, alternatively about 30 to about 45 moi% of the total carboxylic functionality in the composition. Although not wanting to be bound by any particular theory, it is believed that none or few of the esters (whether they are sulfo-estolides or not) are hydrolyzed in the process of making SHP. By processing at a low temperature and neutralizing the acid as it leaves the sulfonator as quickly as possible, it is contemplated that lower ester levels will be obtained. Through optimization of process conditions for production of esters, it is further contemplated that products that have higher ester content will be obtained. For example, it is believed that the ester content may be obtained at lower and/or 1 R higher levels through the selection of the rnoiar ratio of SO3 to alkene functionality used in the sulfonation step, or alternatively or in addition, through the selection of the amount of monounsaturated and/or polyunsaturated fatty acids comprising the unsaturated fatly acid feedstock.
[030] The term "ester hydrolyzed product" ("EHP") is used here to describe a sulfonate composition that is produced from unsaturated fatty acids by sulfonation with SO3 to produce suifo-estoϋde and subsequent hydrolysis of greater than about 95% of the carboxyiic esters. For example, the resulting product may have a carboxylic ester content that corresponds to less than about 5 mol %, alternatively less than about 2 mol%, alternatively less than about 1 mol% of the total carboxylic functionality in the composition.
[031 ] The term "partially ester hydrolyzed products" ("PEHP") is used here to describe salts of sulfo-estolides that are produced from unsaturated fatty acids by sulfonation with SO3 and hydrolysis of a portion of the carboxylic esters. The molar percentage of hydrolysis of carboxylic esters that is realized is from about 1 % to about 95%, alternatively from about 5% to about 90%, alternatively from about 10% to about 90%, alternatively from about 20% to about 90%.
[032] A "repeating unit" means one instance of the subject matter enclosed by brackets in a formula described herein. For example, if n = 15 for a given molecule according to general Formula 1 , the molecule has 15 instances of the bracketed structure. Each instance of the bracketed structure can be identical to or different from other instances of the bracketed structure. For example, the Y moiety in general Formula 1 can be H in one repeating unit and -SO3 Z in another repeating unit of the same molecule.
[033] A suitable starting material for the present process is a fatty acid (fatty carboxylic acid) that may be derived from vegetable and/or animal sources. The compounds of general Formula 1 and related compounds (for example, where n ~ Q) can be made, for example, by: a) SO3 sulfonation of a fatty acid, for example oleic acid; b) neutralization with aqueous caustic to afford a sulfonate salt solution with a pH in the range of about 4 to about 10; or c) hydrolysis of the resulting sultones, maintaining the reaction mixture at a pH of about 4 to about 10. Suifonation can be carried out, for example, using a falling film SO3 process.
[034] Continuous SO3 suifonation processes, including those that utilize falling film reactors such as those described in Kirk-Othmer Encyclopedia of Chemical Technology, 5th ed., Vol. 23, Wiiey-interscience, Hoboken, NJ: 2007, entry entitled "Suifonation and Sulfation", pp. 513-582, which is hereby incorporated by reference, are suitable for conducting the suifonation of feedstocks comprising unsaturated fatty acids in accordance with the presently described technology. For example, a monotube concentric reactor, annular film reactor, or multitube film reactor can be used to contact an unsaturated fatty acid feedstock, for example oleic acid, with a gaseous stream of SO3 that is diluted with dry air. The molar ratio of SO3 to alkene functionality in the fatty acid feedstock may be from about 0.3 to about 1.3, alternatively from about 0.5 to about 1 .2, alternatively from about 0.8 to about 1.1 , alternatively from about 0.9 to about 1.0.
[035] In some embodiments, a preferred ratio, for example, is less than about 0.8 so as to minimize color formation. The fatty acid feedstock is provided to the reactor at a temperature preferably above the melting point of the feedstock, i.e. the feedstock is provided as a liquid. The suifonation is conducted such that the reaction mass is maintained as a mobile liquid throughout the course of reaction. Preferably, a means of cooling the reaction mixture during the course of contact between the feedstock stream and the gaseous SO3 stream is provided so that the sulfonic acid product is produced from the reactor at a temperature of from about 1 O0C to about 8O0C, alternatively from about 2O0C to about 6O0C, alternatively from about 3O0C to about 6O0C.
[038] SE is produced from the suifonation step and comprises carboxylic esters, provided that the reaction conditions are sufficient, for example a high enough temperature of the acid stream, to promote carboxylic ester formation. While not limiting the scope of the presently described technology, the temperature at which carboxylic ester formation may occur is greater than 1 O0C, alternatively greater than 2O0C, alternatively greater than 3O0C. The sulfonic acid products may further comprise sulfonic acid esters, including but not limited to cyclic esters, i.e., sultones. [037] In accordance with at least one embodiment, the presently described technology provides a process of making a sulfo-estolide mixture comprising the steps of:
providing at least one unsaturated fatty carboxylic acid having from about 8 to about 24 carbon atoms;
providing at least one chain termination agent having from about 4 to about 24 carbon atoms;
sulfonating the unsaturated fatty carboxylic acid to form a sulfonated intermediate; and
reacting the chain termination agent with the sulfonated intermediate to form a sulfo-estolide mixture.
hlUlQ\y3}3..oj Sulϊones
[038] In one aspect of the presently described technology where a neutralized SE is produced with a pH of from about 4 to about 10, the neutralized product can be subjected to a hydrolysis step for the purpose of hydrolyzing sultones, sulfonic acid esters, and acid anhydrides.
Hydrolysis of Carboxylic Esters
[039] In one aspect of the presently described technology, carboxylic esters present in SE and optionally SHP may optionally be subjected to an alkaline hydrolysis step for the purpose of converting carboxylic esters into carboxylates to afford EHP and/or PEHP.
Neutral Bleaching,
[040] In at least one embodiment, bleaching of neutralized products of SE may be conducted by treating the products with aqueous hydrogen peroxide, for example 35% H2O2. in a bleaching reaction that is conducted at a temperature of about 20° C to about 150° C, alternatively about 50° C to about 120° C, alternatively about 70° C to about 100° C.
Adjusting pH to Improve Product Stability Against Inhomoqeneity
[041] In some preferred embodiments, a concentrated aqueous solution of
SHP, PEHP, and EHP may be prepared in a process comprising at least the steps of sulfonating a feedstock comprising an unsaturated fatty acid, neutralizing the resulting SE sulfonic acid intermediate, and hydrolyzing sultones. In these preferred embodiments, it is preferable that the pH of the final concentrated aqueous solution to be stored, transported, and optionally handled in additional ways is maintained in a pH range that enables a dear, homogeneous liquid product, free of substantial precipitation or other physical form instability.
Ac|d.Blβach|ng
[042] One way to reduce color is by bleaching SE sulfonic acid before neutralizing, which can be referred to as acid bleaching. Acid bleaching of SE may have the advantage, by itself or in combination with additional bleaching after neutralization, of reducing the color of SE more than would normally be achieved by neutral bleaching as described herein.
Hydrogenation
[043] Another way to reduce the color of SE, which is not believed to be known, is to use a partially hydrogenated feedstock, for example an oleic acid feedstock or a soybean oil feedstock, to reduce or eliminate polyunsaturates. In one contemplated process, the proportion of triunsaturates such as linoienic acid can be reduced or eliminated by hydrogenation.
[044] Further details of SE production are included in United States
Application Serial No. 12/353,751 , which is hereby incorporated by reference.
[045] Again not wanting to be bound by any particular theory, the compositions of the present technology described by general Formula 1 , are believed to be comprised of complex mixtures of compounds that are monomeric, dimeric, and higher-order oligomeric species in terms of the number of originating fatty acid chains. The oligomerization in these mixtures is via the formation of ester linkages. Branched oligomers are also contemplated. Additional information regarding SE compositions of the present technology are present in United States Application Serial No. 12/353,751.
[048] The sulfo-estolide functional group corresponds structurally to the condensation of the hydroxy! group of an internal hydroxy sulfonate of fatty acid with the carboxylic acid group of a second fatty acid chain, where the second fatty acid chain may be, but is not necessarily limited to: a) an unsaturated or saturated fatty acid; b) an internal hydroxy sulfonate of fatty acid; c) an interna! alkene sulfonate or corresponding cyclic anhydride (i.e. sυltone) of fatty acid; or d) an interna! mono- or poly sulfo-estoiide of two or more fatty acids (i.e., trimer, tetramer, etc.). The position of the sulfonate group along the back bone of the fatty acid chains is dictated by the location of the double bond in the starting material (9-octadecenoic acid for example) and the "direction" in which SO3 adds across the double bond (thus, 9- and 10- sulfonate positions from oleic acid).

alkene sulfonate sulfo-estolide
[047] Non-ester-containing monomeric components made by this process are believed to comprise, in part, specific internal hydroxy sulfonates of fatty acid. For example, with 9-octadecenoic acid, the sulfonate groups are believed to be attached to the 9-position and alternatively the 10-position of the fatty acid. Examples are shown below.
Figure imgf000020_0003
[048] The monomeric components are further believed to comprise, in part, specific interna! alkene sulfonates of fatty acid. These components may comprise cis- and/or trans-double bonds. It is also possible that compounds are present where the unsaturation is at the position of the suifonate group (i.e., vinyiic sulfonates). Examples are shown below.
Figure imgf000021_0001
[049] The monomeric components may further comprise disulfonated species, unsaturated fatty acids, and saturated fatty acids.
[050] EHP is sometimes used here as a designation for sulfonated products that have been subjected to complete hydrolysis of sulfo-estolide functionality. Such hydrolysis can be accomplished by, for example, treatment of SHP with excess base under high pH conditions (for example >1 1 ) at elevated temperatures (for example 85-1000C). EHP is believed to comprise a mixture of hydroxyaikane sulfonates and alkene sulfonates of comparable structure to the monomeric components of sulfo- estolide compositions, though not necessarily in comparable ratios. This mixture is comparable in composition to the compositions of sulfonated unsaturated fatty acids that are described in the art, for example, in T. W. Sauls and W, H. C. Rueggeberg, Journal of the American Oil Chemists Society (JAOCS),Volume 33, Number 9, September, 1958, pp 383-389, which is incorporated herein by reference.
[051 ] St can be appreciated that PHEP will be comprised of elevated amounts of monomeric hydroxyaikane sulfonates and aikene sulfonates while maintaining some level of suifo-estolide functionality.
Heavy Duty Liquid (HDL) Laundry Detergents
[052] Desirable attributes for HDLs include, for example, the ability to emulsify, suspend or penetrate greasy or oily soils and suspend or disperse particulates, in order to clean surfaces; and then prevent the soils, grease, or particulates from re-depositing on the newly cleaned surfaces.
[053] The present technology describes the unexpected outcome now found that the addition of magnesium ions to sulfonated estolide HDL formulations 91 enhances soil removal. This believed unexpected and unpredictable result allows production of HDL formulations that are easily manufactured, affordable to produce, and ecQ-friendly/"greerr, in addition to being effective soil removers.
[054] Without wanting to be bound by any particular theory, it is believed that the presence of small amounts of magnesium ions in the laundry liquid improves soil removal due to the divalency of the ions that can provide the formation of larger micelles. Again, not wanting to be bound by any particular theory, it is also believed that high levels of magnesium ions in the laundry liquid may decrease soil removal by increasing soil redeposition and by decreasing the effectiveness of anionic surfactants. Therefore, it is significant that the concentration of magnesium ions be precisely controlled, tailored and tested under various conditions in order to achieve the desired effect of increased soil removal as the present technology now sets forth herein.
[055] Other desirable surfactant attributes for HDL's include, for example, the ability of being in liquid form at room temperature, an ability to be formulated in cold- mix applications, and an ability to perform as well as or better than existing surfactants in, for example, heavy duty liquid detergent applications.
[058] St is also desirable to have the ability to control the foaming - for use of an HDL in a high efficiency (it should be appreciated that all high efficency ("HE") washing machines includes all front loading washing machines as well) washing machine, low foam is desired to achieve the best cleaning and to avoid excess foaming. Other desirable properties include, but are not limited to, the abiiity to clarify the formulation and to improve stability. HDL formulations of the present technology, which contain both SE and magnesium ions perform effectively in HE washing machines.
[057] Formulations of the present technology are contemplated as having, for example, a viscosity of 5cPs to 200OcPs1 measured at 25° C using a Brookfield Viscometer model LV, spindle #2, at a speed of 5 rpm. Certain SHP, PEHP, or EHP formulations have been found to have lower viscosity than comparable formulations lacking these surfactants, so such compositions function as viscosity reducers, which 99 is very useful for making the contemplated highly concentrated, (e.g., greater than 40% surfactant active) detergent formulations.
[058] The present technology has unexpectedly revealed that sulfonated estolide formulations that include magnesium ions as described and claimed herein have an increased viscosity when compared to formulations that do not contain magnesium ions. Therefore, addition of magnesium ions to the presently described laundry detergent formulations may be useful for viscosity adjustment. Utilization of substances that build viscosity (such as magnesium sulfate) and substances that decrease viscosity (such as SHP, PEHP, or EHP) enables enhanced control of formulation viscosities and the production of detergent compositions with desirable viscosities, while maintaining ease of production, affordability, eco-friendiiness, and effective soil removal. Such advantages/outcomes, are believed to be achieved by the compositions of the present technology.
Detergent Compositions
[059] A wide variety of magnesium ion containing detergent compositions can be made that include SE, PHSE, HSE, SHP, PEHP, EHP1 or combinations of two or more of such compositions, as described herein, with or without other ingredients as specified below. Formulations are contemplated including about 1 % to about 99% SE, PHSE, HSE, SHP, PEHP, and/or EHP. more preferably between about 1 % and about 60%, even more preferably between about 1 % and about 30%, with about 99% to about 1 % water as a vehicle, carrier, diluent, etc. Other suitable carriers/vehides/dϋuents are also envisaged. As will be appreciated by at least those skilled in the art, a variety of carriers, vehicles, diluents, and the like are suitable for use in the practice of the present technology. Thus, it will also be appreciated that the terms "carrier", "vehicle", and "diluent" are to be considered non-exhaustive with respect to the present technology and in describing the various formulations, applications, compositions, et cetera thereof.
[060] The present technology provides detergent compositions that contain magnesium ions in addition to SE, PHSE, HSE, SHP, PEHP, EHP, or combinations of two or more of such compositions. Formulations containing 0% to about 5% magnesium sulfate are contemplated. More preferably, compositions containing between about 0.5% and about 3% magnesium sulfate are also contemplated. Most preferably, compositions contain about 0.5% to about 2,0% magnesium sulfate are also contemplated.
[081] Optionally, other ingredients as described here or in United States
Application Serial No. 12/353,751 may be included in the laundry detergent compositions of the present technology.
[062] The magnesium ion containing sulfonated estolide formulations of the present technology can contain co-surfactants, which can be, for example, anionic, cationic, nonionic, ampholytic (includes usage of the term amphoteric), zwitterionic, or combinations thereof. Additional information regarding surfactants that may be suitable in compositions of the present technology is presented in United States Application Serial No. 12/353,751
AnJon.ic^S.urfactants
[063] Although it is preferred that SHP be the only anionic surfactant used in the formulation, other anionic surfactants can be added. "Anionic surfactants" are defined here as amphophilic molecules with an average molecular weight of less than about 10,000, comprising one or more functional groups that exhibit a net anionic charge when in aqueous solution at the normal wash pH, which can be a pH between about 8 to about 1 1. The anionic surfactant used in the present technology can be any anionic surfactant that is substantially water soluble. "Water soluble" surfactants are, unless otherwise noted, herein defined to include surfactants which are soluble or dispersible to at least the extent of about 0.01 % by weight in distilled water at about 25°C. It is preferred that at least one of the anionic surfactants used in the present technology be an alkali or alkaline earth metal salt of a natural or synthetic fatty acid containing between about 4 to about 30 carbon atoms. It is especially preferred to use a mixture of carboxyiic acid salts with one or more other anionic surfactants. Another important class of anionic compounds is the water soluble salts, particularly the alkali metal salts, of organic sulfur reaction products having in their molecular structure an aikyl radical containing from about 8 to about 24 carbon atoms and a radical selected from the group consisting of sulfonic and sulfuric acid ester radicals. CatSonic Surfactants
[064] Specific cationic surfactants contemplated for use in the present compositions include ditallow dimethylammonium chloride (DTDMAC), fatty alkanolamides (FAA), and quaternized diesters of trialkanoiamines and fatty acids. The proportions of cationic surfactants used in a formulation can range, for example, from about 0.1 % to about 20%, more preferably between about 1 % to about 10%, even more preferably between about 1 % to about 5%. See also P&G US patent 5,929,022; column 6, 2nd paragraph through column 7, 1 st paragraph.
Nonionic Surfactants
[065] Examples of suitable nonionic surfactants include, for example, alkyl polygiucosides ("APGs), alcohol ethoxylates, nonylphenol ethoxylates, and others. The nonionic surfactant may be used in an amount of from about 1 % to about 90%, more preferably from about 1 % to about 40% and most preferably between about 1 % to about 32% of a desired detergent composition. Other suitable nonionic surfactants are described in P&G patent 5,929,022; column 4, 2nd paragraph through column 6, end of 1 ST paragraph, which is incorporated herein by reference. A preferred nonionic surfactant of the present technology is the fatty alcohol ethoxyiate, BIO-SOFT® N25-7 (C12-15EO7), which can be purchased from Stepan Company (Northfieid, IL).
Am£hQ]yfi£ Surfactants
[066] Ampholyte (includes usage of the term amphoteric) synthetic detergents can be broadly described as derivatives of aliphatic or aliphatic derivatives of heterocyclic secondary and tertiary amines, in which the aliphatic radical may be straight chain or branched and where one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and at least one contains an anionic water-solubilizing group, e.g., carboxy, suifo, sulfato, phosphato, or phosphono (see, e.g., U.S. Patent No. 3,884,961 , which provides specific examples of ampholyte surfactants from col. 6, line 80, to col. 7, line 53, incorporated here by reference). Examples of suitable ampholyte surfactants include fatty amine oxides and fatty amidopropylamine oxides. A specific suitable example is cocoamidopropyl betaine (CAPB) also known as coco betaine. Ampholytic surfactants can be used at a level OR from about 1 % to about 50%, more preferably from about 1 % to about 10%, even more preferably between about 1 % to about 5% of the formulation, by weight.
Zwitterionic Surfactants
[067] Zwilterionic synthetic detergents can be broadly described as derivatives of aliphatic quaternary ammonium and phosphonium or tertiary sulfonium compounds, in which the cationic atom may be part of a heterocyclic ring, and in which the aliphatic radical may be straight chain or branched, and where one of the aliphatic subsiiiuents contains from about 3 to about 18 carbon atoms, and at least one aliphatic substituent contains an anionic water-soiubilizing group, e.g., carboxy, sulfo, sulfate, phosphate, or phosphono. (see e.g., U.S. Patent No. 3,884,961 , which provides specific examples of zwitterionic surfactants from col. 7, line 65, to col. 8. line 75, incorporated here by reference). Zwitterionic surfactants can be used as from about 1 % to about 50%, more preferably from about 1 % to about 10%, even more preferably from about 1 % to about 5% by weight of the present formulations.
■Mlxlyies.M..Surfacta.Qls
[068] Mixtures of any two or more individually contemplated surfactants, whether of the same type or different types, are contemplated herein.
Laundry Detergent Compositiosifs)
[089] The formulation and use of magnesium ion containing sulfonated estolide compositions of the present technology will now be illustrated in more detail for a laundry detergent composition.
[070] Four desirabie characteristics of a laundry detergent composition, in particular a liquid composition (although the present disclosure is not limited to a liquid composition, or to a composition having any or ail of these attributes) are that (1 ) a concentrated formulation is useful to save on shelf space of a retailer, (2) a "green" or environmentally friendly composition is useful, (3) a composition that works in modern high efficiency washing machines which use less energy and less water to wash clothes than previous machines is useful, and/or (4) a composition that cleans well in lower temperature water for example iess than 70° F, and/or (5) a composition that exhibits a pH of about 5 to about 13.5. [071 ] To save a substantial amount of retailer shelf space, a concentrated formulation is contemplated having two or even three four, five, six, or even greater (e.g., 8x) times potency per unit volume or dose as conventional laundry detergents. The use of less water can complicate the formulation of a detergent composition, as it needs to be more soluble and otherwise to work well when diluted in relatively little water.
[072] To make a "green" formula, the surfactants should be ultimately biodegradable and non-toxic. To meet consumer perceptions and to reduce the use of petrochemicals, a ''green" formula may also advantageously be limited to the use of renewable hydrocarbons, such as vegetable or animal fats and oils, in the manufacture of surfactants. The magnesium sulfate containing HDL formulations of the present technology are consistent with the production of a "green" composition, since magnesium sulfate is known to be a natural component of ocean water which presents no toxicological or safety concerns.
[073] High efficiency (HE) washing machines present several challenges to detergent formulating. As of January 201 1 , all washing machines sold in the US must be HE, at least to some extent, and this requirement will only become more restrictive in the coming years. Front loading machines, ail of which are HE machines, represent the highest efficiency, are increasingly being used.
[074] Heavy duty liquid (HDL) detergent formulas are impacted by HE machines because the significantly lower water usage requires that less foam be generated during the wash cycle. As the water usage levels continue to decrease in future generations of HE machines, detergents may be required to transition to no foam. In addition, HE HDLs should also disperse quickly and cleanly at lower wash temperatures.
[075] To work in a modern high efficiency washing machine, the detergent composition needs to work in relatively concentrated form in cold water, as these washing machines use relatively little water and cooler washing temperatures than prior conventional machines. The sudsing of such high-efficiency formulations must also be reduced, or even eliminated, in a low-water environment to provide effective cleaning performance. The anti-redeposition properties of a high efficiency detergent formulation also must be robust in a low-water environment. In addition, 97 formulations that allow the used wash water to be more easily rinsed out of the clothes or spun out of the clothes in a washing machine are also contempiated, to promote efficiency.
[076] Liquid fabric softener formulations and "softergent" (fabric softener/detergent dual functional) single-add formulations also may need to change as water usage continues to decline in HE machines. A washer-added softener is dispensed during the rinse cycle in these machines. The present SE, PHSE, and HSE compositions provide some softening activity, which is contemplated to address these challenges, among others.
[077] Laundry detergent formulations, containing magnesium ions, sulfonated estolides and additives, of the present technology are contemplated to provide high concentration formulations, or "green" formulations, or formulations that work well in high efficiency washing machines, for example. Such detergents and additives are contemplated that have at least one of the advantages or desirable characteristics specified above, or combinations of two or more of these advantages, at least to some degree. The ingredients contemplated for use in such laundry detergents and additives are further described, for example, in the following paragraphs.
[078] In addition to the surfactants as previously described, a laundry detergent composition commonly contains other ingredients for various purposes. Formulations of the present technology are contemplated that contain from about 0% to about 40% by weight of at least one additive including, but not limited to, the ingredients described below.
Builders and Alkaline Agents
[079] Builders and other alkaline agents are contemplated for use in the formulations of the present technology. Any conventional builder system is suitable for use in connection or conjunction with the present technology, including, but not limited to, aluminosilicate materials, silicates, polycarboxylates and fatty acids, materials such as ethylenediamine tetraacetate, metal ion sequestrants such as aminopoiyphosphonales, particularly ethylenediamine tetramethylene phosphonic acid and diethylene triamine pentamethyienephosphonic acid. Though less preferred for obvious environmental reasons, phosphate builders could also be used here. For example, suitable poiycarboxyiate builders include citric acid, preferably in the form of a water-soluble salt, and derivatives of succinic acid of the following formula:
R-CH(COOH)CH2(COOH)
where R is do 20 alkyi or aikenyl, preferably C12 16, or where R can be substituted with, for example, hydroxy!, suifo suifoxyl or sulfone subsfifuents. Specific examples include iauryl succinate, myristyl succinate, palmityl succinate 2-dodecenylsuccinate, or 2-tetradecenyl succinate. Succinate builders are preferably used in the form of their water-soluble salts, including, but not limited to, sodium, potassium, ammonium and alkanolammonium salts. Preferred builders of the currently presented technology contain sodium citrate dihydrate, monoethanoiamine, and triethanoiamine.
[080] Other suitable polycarboxylates are oxodisuccinates and mixtures of tartrate monosuccinic and tartrate disuccinic acid, as described in U.S. Pat. No. 4,683,071 , which is incorporated herein by reference.
[081 ] For a liquid detergent composition, suitable fatty acid builders for use in connection or conjunction with the present technology can be, for example, saturated or unsaturated C10-18 fatty acids, as well as the corresponding soaps. Preferred saturated species have from about 12 to about 18 carbon atoms in the alkyl chain. The preferred unsaturated fatty acid is oleic acid. Another preferred builder system for liquid compositions is based on dodecenyl succinic acid and citric acid.
[082] Some examples of alkaline agents include alkalic metal (Na+, U, or
NH4 h) hydroxides, carbonates, bicarbonates. Another commonly used builder is borax. For powdered detergent compositions, the builder or alkaline agent typically comprises from about 1 % to about 95% of the composition. For liquid compositions, the builder or alkaline agent typically comprises from about 1 % to about 80%, alternatively between about 1 % to about 30%, alternatively between 2% to about 15%. See US patent 5,929,022; column 7. start of 2nd paragraph through column 7. end of 8th paragraph, from which much of the preceding discussion comes. Other builders are described in PCT Publ. WO 99/05242, which is incorporated here by reference. Enzymes
[083] The magnesium ion containing sulfonated estolide formuiations of the present technology may further comprise one or more enzymes, which provide cleaning performance and/or fabric, care benefits. Suitable enzymes for use in the present technology include, but are not limited to. enzymes selected from celluiases. hemicelluiases, peroxidases, proteases, gluco-amyiases, amylases, lipases, cutinases, pectinases, xyianases, reductases, oxidases, phenoloxidases, lipoxygenases, ϋgninases, puliulanases, tannases, pentosanases, malanases, beta- glucanases, arabinosidases, derivatives thereof or mixtures thereof.
[084] A preferred combination is a detergent composition having a cocktail of conventional applicable enzymes like protease, amylase, lipase, cutinase and/or celiulase in combination or conjunction with the lipolytic enzyme variant D98L at a level of from about 50 LU to about 8500 LU per liter wash soiution.
[085] The ceilulases usable in the practice of the present technology include, but are not limited to, both bacterial or fungal celiulase. Preferably, they will have a pH optimum of between about 5 and about 9.5. Suitable ceilulases are disclosed in U.S. Pat. No. 4,435,307, Barbesgoard et ai, which discloses fungal celiulase produced from Humicoia insolens. Suitable celiulases are aiso disclosed in GB-A-2 075 028; GB-A-2 095 275 and DE-OS-2 247 832, which are incorporated herein by reference.
[088] Examples of such celluiases are ceilulases produced by a strain of
Humicoia insoiens (Humicoia grisea var. thermoidea), particularly the Humicoia strain DSM 1800. Other suitable ceilulases are celluiases originated from Humicoia insolens having a moiecular weight of about 50KDa, an isoelectric point of about 5.5 and containing 415 amino acids. Especially suitable celiulases are the celiulases having color care benefits. Examples of such celiulases are ceilulases described in European patent application No. 91202879.2, filed Nov. 6, 1991 (Novo).
[087] Peroxidase enzymes are used in combination with oxygen sources, e.g. percarbonate, perborate, persulfate, hydrogen peroxide, etc. Sn particular, they are used for "solution bleaching", i.e. to prevent transfer of dyes or pigments removed from substrates during wash operations to other substrates in the wash solution. Peroxidase enzymes are known in the art, and include, for example, horseradish peroxidase, ligninase, and haloperoxidase such as chloro- and bromo- peroxidase. Peroxidase-containing detergent compositions are disclosed, for example, in PCT International Application WO 89/099813 and in European Patent application EP No. 91202882,6, filed on Nov. 6, 1991. Cellulases and/or peroxidases can be incorporated in a detergent composition(s) of the present technology at levels from about 0.0001 % to about 2% of active enzyme by weight of the detergent composition.
[088] Preferred commercially available protease enzymes include, for example, those sold under the tradenames Alcalase®, Savinase®, Primase®, Durazym®, and Esperase® by Novo Nordisk A/8 (Denmark), those sold under the tradename Maxatase®, Maxacai® and Maxapem® by Gist-Brocades (Netherlands), those sold by Genencor International (Rochester NY), and those sold under the tradename Opticlean® and Optimase® by Solvay Enzymes (Brussels, Belgium). Other proteases are described in U.S. Patent No. 5,879,630, issued Oct. 21 , 1997 (P&G), which is incorporated by reference herein, can be included in the detergent composition of the present technology. Protease enzymes may be incorporated into the compositions in accordance with the present technology at a level of from about 0.0001 % to about 2% active enzyme by weight of the composition.
[089] A preferred protease for use in practicing the present technology is referred to as "Protease D" and is a carbonyi hydrolase variant having an amino acid sequence not found in nature, which is derived from a precursor carbonyi hydrolase by substituting a different amino acid for the amino acid residue at a position in said carbonyi hydrolase equivalent to position +76, preferably also in combination with one or more amino acid residue positions equivalent to those selected from the group consisting of +99, +101 , +103, +104, +107, +123, +27, +105, +109, +126, +128, +135, +156, +166, +195, +197, +204, +206, +210, +216, +217, +218, +222, +260, +265, and/or +274 according to the numbering of Bacillus amyloliquefaciens subtiiisin, as described in U.S. Patent No. 5,679,830, issued Oct. 21 , 1997, which is incorporated here by reference in its entirety.
[090] Highly preferred enzymes that can be included in the detergent compositions of the present technology include lipases. It has been unexpectedly found that the cleaning performance on greasy soils is synergistically improved by using lipases in one or more formulations of the present technology. Suitable lipase enzymes include, for example, those produced by microorganisms of the Pseudomonas group, such as Pseudomonas stutzeri ATCC 19.154, as disclosed in British Patent 1 ,372,034. Suitable lipases include those which show a positive immunological cross-reaction with the antibody of the lipase, produced by the microorganism Pseudomonas fluorescens IAM 1057. This lipase is available from Amano Pharmaceutical Co. Ltd.. Nagoya, Japan, under the trade name Lipase P "Amano," hereafter referred to as "Amano-P". Further suitable lipases are lipases such as M1 Lipase'^ and Lipomax® (commercially available from Gist-Brocades). Highly preferred lipases are the D96L lipolytic enzyme variant of the native lipase derived from Humicola lanuginosa as described in U.S. Patent No. 8,017,871 issued January 25, 2000 (P&G). Preferably the Humicola lanuginosa strain DSM 4106 is used. This enzyme is incorporated into one or more compositions in accordance with the present technology at a level of from about 50 LU to about 8500 LU per liter wash solution. Preferably, the variant D96L is present at a level of from about 100 LU to about 7500 LU per liter of wash solution. More preferably at a level of from about 150 LU to about 5000 LU per liter of wash solution.
[091 ] By D98L lipolytic enzyme variant is meant the lipase variant as described in patent application WO 92/05249 where the native lipase ex Humicola lanuginosa aspartic acid (D) residue at position 96 is changed to Leucine (L). According to this nomenclature the substitution of aspartic acid to Leucine in position 96 is shown as: D98L.
[092] Also suitable are culinases [EC 3.1.1 .50] which can be considered as a special kind of lipase, namely lipases which do not require interfacial activation. Addition of cutinases to detergent compositions have been described in e.g. WO-A- 88/09367 (commercially available from Genencor), which is incorporated herein by reference. The lipases and/or cutinases are normally incorporated in one or more detergent compositions of the present technology at levels from about 0.0001 % to about 2% of active enzyme by weight of the detergent composition.
[093] Amylases (α and/or β) can be included for removal of carbohydrate- based stains. Suitable amylases can be, for example, Termamyi^ (commercially available from Novo Nordisk, Denmark), FungamyP and BAN® (Novo Nordisk). [094] The above-mentioned enzymes may be of any suitable origin, such as vegetable, animal, bacterial, fungal and/or yeast origin. See e.g.. US patent 5,929,022; column 7, 7th paragraph through column 9, 6th paragraph, from which much of the preceding discussion comes. Preferred compositions optionally contain a combination of enzymes or a single enzyme, with the amount of each enzyme commonly ranging from about 0.0001 % to about 2% in one or more compositions of the present technology. Other enzymes and materials used with enzymes are described in PCT Publ. WG99/05242, which is incorporated here by reference.
[095] Enzymes are expected to exhibit excellent shelf life in SHP-containing
HDLs. Not to be bound by theory, it is believed that surfactants with low critical micelle concentration (CMC) values tend to be more mild to enzymes based on low monomer concentrations in solution which interfere with enzyme stability. The measured CMC, via the Wϋhelmy plate technique, of SHP is approximately 30 mg/L while that of the sodium salt of AES is approximately 80 mg/L and NaLAS is approximately 900 mg/L.
Enzyme Stabilizers
[096] When enzymes, and especially proteases, are used in liquid detergent formulations, it is often necessary to include a suitable quantity of enzyme stabilizer to temporarily deactivate the enzyme until it is used in the wash. Examples of suitable enzyme stabilizers are well-known to those skilled in the art, and include, for example, borates and polyols such as propylene glycol. Borates are especially suitable for use as enzyme stabilizers because in addition to this benefit, they can further buffer the pH of the detergent product over a wide range, thus providing excellent flexibility.
Adjuvants
[097] The magnesium ion containing sulfonated estolide formulations of the present technology optionally can contain one or more soil suspending agents or resoiling inhibitors in an amount from about 0.01 % to about 5% by weight, alternatively less than about 2% by weight. Resoiling inhibitors include, for example, anti-redeposition agents, soil release agents, or combinations thereof. Examples of suitable agents are described in US patent 5,929,022 (Velasquez); column 10, 3rd paragraph through column 10, 5th paragraph, and include water-soluble ethoxylated amines having clay soil removal and anti-redeposition properties. Examples of such soil release and anti-redeposition agents given in the referenced patent include an ethoxylated tetraethylenepentamine. The ethoxylated amines further described in U.S. Pat. 4,597.898, VanderMeer, issued JuL 1 , 1986. are incorporated here by reference. Another group of preferred clay soil removal/anti-redeposition agents are the cationic compounds disclosed in European Patent Application 1 1 1 ,965 (Oh and Gosseϋnk), published Jun. 27. 1984, incorporated here by reference. Other clay soil removal/anti-redeposition agents which can be used include, for example, the ethoxylated amine polymers disclosed in European Patent Application 1 1 1 ,984 (Gosselink) published Jun. 27, 1984; the zwitterionic polymers disclosed in European Patent Application 1 12,592 (Gosselink), published JuI. 4, 1984; and the amine oxides disclosed in U.S. Pat. No. 4,548,744 (Connor), issued Oct. 22, 1985, all of which are incorporated here by reference.
[098] Other clay soil removal and/or anti-redeposition agents known in the art can also be utilized in the compositions of the present technology. Another type of preferred anti-redeposition agent includes the carboxymethylcellulose materials.
[099] For example, optionally, anti-redeposition polymers can be incorporated into HDL formulations of the presently described technologies. In at least some embodiment, it is preferred that the level of anti-redeposition polymer be below about 2%.

Fatty Acid
[0108] Similar to that disclosed in, for example, US Patent 4,561 ,998, the compositions of the present technology may contain from about 5% to about 40%, preferably from about 7% to about 30%, most preferably from about 10% to about 20%, by weight of a fatty acid containing from about 10 to about 22 carbon atoms. The fatty acid can also contain from 1 to about 10 ethylene oxide units in the hydrocarbon chain.
[0109] Suitable fatty acids are saturated and/or unsaturated and can be obtained from natural sources such as, for example, plant or animal esters (e.g., palm kernel oil, palm oil, coconut oil, babassu oil, safflower oil, tail oil, castor oil, tallow and fish oils, grease, and mixtures thereof) or synthetically prepared (e.g., via the oxidation of petroleum or by hydrogenation of carbon monooxide via the Fisher- Tropsch process). Examples of suitable saturated fatty acids for use in the compositions of the present technology include, but are not limited to capric, lauric, myristic, palmitic, stearic, arachidic and behenic acid. Suitable unsaturated fatty acid species can include, for example, palmitoleic, oleic, iinoleic, linolenic and ricinoleic acid.

Softerqent
[01 10] Softergent technologies as described in, for example, US Patents
6,949,498, 5,468,394 and 5,622,925 can be used in the practice of compositions of the present technology. The term "softergent" refers to a softening detergent that can be dosed or measured at the beginning of a wash cycle for the purpose of simultaneously cleaning and softening fabrics. The magnesium ion containing sulfonated estolide formulations of the present technology can be used to make stable, aqueous heavy duty liquid laundry detergent compositions containing a fabric-softening agent that provide exceptional cleaning as well as fabric softening and anti-static benefits.
[01 1 1] For example, a softergent composition of the present technology can contain about 0.5% to about 10%, preferably from about 2% to about 7%, more preferably from about 3% to about 5% by weight of a quaternary ammonium fabric- softening agent having the following formula:
K4 8,
\ /
N
/ \
wherein R1 and R2 are individually selected from the group consisting of Ci -C4 alky!, Ci-C4 hydroxy alkyi, benzyl, and --(02H4O)x H where x has a value from 2 to 5; X is an anion; and (1 ) R3 and R4 are each a Cs-Ci4 alkyl or (2) R3 is a Ce-Cz? alkyl and R4 is selected from the group consisting of C1-C10 alkyl, C-CJO hydroxy alky!, benzyl, and — (C2 H4O)x H where x has a value from 2 to 5.
[01 12] Preferred fabric-softening agents are the mono-long chain alky! quaternary ammonium surfactants wherein the above formula Ri, R2, and R3 are each methyl and R4 is a C&-C18 aikyl. The most preferred quaternary ammonium surfactants are the chloride, bromide and methylsulfate Cs-ie alky! trimethy! ammonium salts, and Cs iβ alky! di(hydroxyethyl)-methyi ammonium salts. Of the above, laury! trimethyl ammonium chloride, myristyl trimethyi ammonium chloride and coconut trimethyiammonium chloride and methylsulfate are particularly preferred. For example, ADOGEN 412™, a laury! trimethyl ammonium chloride commercially available from Witco (Dublin OH) is a preferred softening agent.
[01 13] Another class of preferred quaternary ammonium surfactants are the di-C8-Ci4 alky! dimethyl ammonium chloride or methylsulfates; particularly preferred is di- C12-C14 alkyl dimethyl ammonium chloride. This class of materials is particularly suited to providing antistatic benefits to fabrics. Materials having two alkyl chain lengths longer than Cu, like di-Ci6-Ci8 alkyl dimethyl ammonium chloride, which are commonly used in rinse added fabric softeners, are not included in the presently described technology, since they do not yield isotropic liquid detergents when combined with the anionic surfactants described above.
[01 14] A preferred soffergent embodiment of the present technology comprises the detergent composition wherein the weight ratio of anionic surfactant component to quaternary ammonium softening agent is from about 3:1 to about 40: 1 and a preferred range from about 5:1 to 20:1.
Odor Control
[01 15] Odor control technologies as described in, for example, US Patent
6,878,695 can be used in the practice of compositions of the present technology.
[01 16] For example, a composition containing magnesium ions and one or more of the sulfonated estolides of fatty acids of the present technology can further comprise a low-degree of substitution cydodextrin derivative and a perfume material. The cydodextrin is preferably functionally-available cydodextrin. The compositions can further comprise optional cyclodexlrin-compatible and-incompatible materials, and other optional components. Such a composition can be used, for example, for capturing unwanted molecules in a variety of contexts, preferably to control malodors including controlling malodorous molecules on inanimate surfaces, such as fabrics, including carpets, and hard surfaces including countertops, dishes, floors, garbage cans, ceilings, walls, carpet padding, air fillers, and the like, and animate surfaces, such as skin and hair.
[01 17] The low-degree of substitution cyclodextrin derivatives useful in the practice of the present technology are preferably selected from low-degree of substitution hydroxyalkyl cyclodextrin, low-degree of substitution alkylated cyclodextrin, derivatives thereof, and mixtures thereof. Preferred low-degree of substitution hydroxyaikyl beta-cyciodextrins have an average degree of substitution of less than about 5.0, more preferably less than about 4.5, and still more preferably less than about 4.0. Preferred low-degree of substitution alkylated cyclodextrins have an average degree of substitution of less than about 8.0, more preferably less than about 5.5, and still more preferably less than about 5.0.
[01 18] The compositions of the present technology can comprise a mixture of cyciodextrins and derivatives thereof such that the mixture effectively has an average degree of substitution equivalent to the low-degree of substitution cyciodextrin derivatives described hereinbefore. Such cyclodextrin mixtures preferably comprise high-degree of substitution cyclodextrin derivatives (having a higher average degree of substitution than the low-degree substitution cyclodextrin derivatives described herein) and non-derivatized cyciodextrin, such that the cyciodextrin mixture effectively has an average degree of substitution equivalent to the low-degree of substitution cyclodextrin derivative. For example, a composition comprising a cyclodextrin mixture containing about 0.1 % non-derivatized beta- cyciodextrin and about 0.4% hydroxypropyl beta-cyciodextrin having an average degree of substitution of about 5.5, exhibits an ability to capture unwanted molecules similar to that of a similar composition comprising low-degree of substitution hydroxypropyl beta-cyciodextrin having an average degree of substitution of about 3.3. Such cyclodextrin mixtures can typically absorb odors more broadly by compiexing with a wider range of unwanted molecules, especially malodorous molecules, having a wider range of molecular sizes preferably at least a portion of a cyciodextrin mixture is alpha-cyclodextrin and its derivatives thereof, gamma- cyciodextrin and its derivatives thereof, and/or beta-cyciodextrin and its derivatives thereof; more preferably a mixture of alpha-cyclodextrin, or an alpha-cyciodextrin derivative, and derivatized beta-cyclodextrin, even more preferably a mixture of derivatised alpha-cyciodextrin and derivatized beta-cyclodextrin; and most preferably a mixture of hydroxypropyl alpha-cyclodextrin and hydroxypropyi bθta-cyciodexlrin, and/or a mixture of methylated alpha-cyclodextrin and methylated beta-cyclodextrin,
[01 19] The cavities within the functionally-available cyciodextrin in the compositions of the present technology should preferably remain essentially unfilled (i.e. the cyciodextrin remains uncomplexed and free) or filled with only weakly complexing materials when in solution, in order to allow the cyciodextrin to absorb (i.e. complex with) various unwanted molecules, such as malodor molecules, when the composition is applied to a surface containing the unwanted molecules. Non- derivatized (normal) beta-cyclodextrin can be present at a level up to its solubility limit of about 1 .85% (about 1.85 g in 100 grams of water) at room temperature. Beta-cyciodextrin is not preferred in compositions which call for a level of cyciodextrin higher than its water solubility limit. Non-derivatized beta-cyclodextrin is generally not preferred when the composition contains surfactant since it affects the surface activity of most of the preferred surfactants that are compatible with the derivatized cyciodextrins.
[0120] The level of low-degree of substitution cyciodextrin derivatives that are functionally-available in the odor control compositions of the present technology is typically at least about 0.001 %, preferably at least about 0.01 %, and more preferably at least about 0.1 %. by weight of the composition. The total level of cyciodextrin in the present composition will be at least equal to or greater than the level of functionally-available cyciodextrin. The level of functionally-available will typically be at least about 10%, preferably at least about 20%, and more preferably at least about 30%, by weight of the total level of cyciodextrin in the composition.
[0121] Concentrated compositions can also be used. When a concentrated product is used, i.e., when the total level of cyciodextrin used is from about 3% to about 80%, more preferably from about 5% to about 40%, by weight of the concentrated composition, it is preferable to dilute the concentrated composition before treating fabrics in order to avoid staining. The resulting diluted compositions have usage concentrations of total cyciodextrin and functionally-available cyciodextrin as discussed hereinbefore, e.g., of from about 0.1 % to about 5%, by weight of the diluted composition of total cydodextrin and usage concentrations of functionally-available cydodextrin of at least about 0.001 %, by weight of the diluted composition.
Forms
[0122] Compositions containing magnesium ions and one or more of the sulfonated estoiides of fatty acids of the present technology can take any of a number of forms and any of the different delivery systems that are currently known or to be developed in the future such as ready-to-use, dilutable, wipes, etc. For example, the compositions of the present technology can take the form of a dilutable fabric detergent or conditioner, that may be an isotropic liquid, a surfactant- structured liquid, a granular, spray-dried or dry-blended powder, a tablet, a paste, a molded solid, a water soluble sheet, or any other laundry detergent form known to those skilled in the art. A "dilutable" fabric detergent or conditioning composition is defined, for the purposes of this disclosure, as a product intended to be used by being diluted with water or a non-aqueous solvent by a ratio of more than, for example, 100:1 , to produce a liquor suitable for treating textiles. "Green concentrate" compositions like those on the market today for Fantastic®, Windex® and the like, can be formulated such that they could be a concentrate to be added to a bottle for final reconstilution.
[0123] The compositions of the present technology could also be formulated as a gel or a gel packet like the dishwasher products on the market today. Water soluble sheets or sachets, such as those described in U.S. Pat. Appl. No. 20020187909, which is incorporated herein by reference, are also envisaged as a potential form of the present technology. These may be sold under a variety of names, and for a number of purposes. The composition can also be deposited on a wiper or other substrate.
MeIhOdS111Of ιLauιnιderinιc{ιιιFaιbriιcs
[0124] Methods for laundering fabrics with magnesium ion containing sulfonated estolide formulations of the present technology are contemplated. Such methods involve placing fabric articles to be laundered in a high efficiency washing machine or a regular (non-high efficiency) washing machine and placing an amount of the SE, PHSE, or HSE-based composition sufficient to provide a concentration of the composition in water of from about 0.001 % to about 5% by weight when the machine is operated in a wash cycle. A high efficiency machine is defined by the Soap and Detergent Association as any machine that uses about 20% to about 68% of the water, and as little as about 20% to about 50% of the energy, of a traditional, regular agitator washer (SDA "Washers and Detergents" publication 2005; http://www.cleaninq101.com/iaundrv/HE.pdf. The wash cycle is actuated or started to launder the fabric articles.
EXAMPLES
[0125] The compositions and processes described here, and ways to make and use them are illustrated by the following examples. Examples stated in the present or future tense are not represented as having been carried out. Examples to the methods of producing and testing sulfo-estolides of the present technology are incorporated by reference in their entirety from PCT Application Serial No. PCT/US09/31608 filed on January 21 , 2009, Examples 1-26.
EXAMPLE 1 : EFFECT OF ADDITION OF MAGNESIUM IONS AS MAGNESIUM
SULFATE TO SULONATED ESTOLIDE CONTAINING HDL LAUNDRY
DETERGENT FORMULATIONS
[0126] Sulfonated βstolidβ containing HDL laundry detergent formulations with magnesium sulfate added were produced and tested in order to ascertain the effect of magnesium ions on soil removal. The detergents were tested with two different magnesium sulfate concentrations, approximately 1 % and 2% weight as is. The formulations were tested over a wide pH range (pH of about 7, about 8.25, about 9.5, about 10.75, and about 12} in order to encompass formulations for economy, medium, and premium tier HDL products.
[0127] The sulfonated estoiide sample used in this example is designated SE.
SE was produced from 100% Oleic acid feed stock. The final product was the result of neutralization, hydrolysis, and bleaching (using 1.1 % by weight of 50% H2G2 per acid flow). The final product consisted of 71 .37% solids at a pH of 5.02 with a %K24 of 2.41. The feedstock used in this example had an equivalent weight of about 275.06 and was comprised of about 78% C-18:1 , about 12% C-18:2, and about 9% saturated fatty acids. The feedstock was sulfonated on a falling film reactor at a rate of about 129.3 lbs per hour using a molar ratio of SO3 to alkene functionality of about 0.95. The SE sulfonic acid was continuously neutralized in a loop reactor with concurrent addition of about 49.1 lbs per hour of 45% aqueous KOH and about 37.9 lbs per hour of water. The temperature of the reaction mixture in the loop reactor was about 8O0C. Neutralized SE solution was continuously fed from the loop reactor to an in-line mixer, where about 2.61 lbs per hour of 50% aqueous hydrogen peroxide was homogenized into the solution, which was about pH 5.8. This reaction mixture was then fed to a stirred tank reactor. After collecting about 80 gallons of reaction mixture, concurrent suitone hydrolysis and bleaching were continued at about 8O0C for about 4 additional hours. Af the end of this 4 hour hydrolysis and bleaching period about 16.5 lbs of 38% sodium bisulfite solution was added to the reaction mixture to reduce the residual peroxide in solution from about 0.25 % (wt/wl) active peroxide down to about 0.02% (wt/wt) active peroxide. The SHP produced from this reaction was at a pH of about 5.0, was comprised of about 89.8% solids and about 0.017 % (wt/wt) active peroxide, and had a Klett color at 1 percent solids concentration of 51. The EHP was analyzed by titration with aqueous HCI and was found to comprise about 40.8 mo! percent of the carboxyiic ester.
[0128] The HDL compositions utilized in this example are presented in Table
1 :

ΕIO-SOFT® N25-7 (Ci2-I5EO7), Stepan Company, Northfield, Il
** Neolone M10 (CiH5NOS), Rohm and Haas, Philadelphia, PA. [0129] The HDL formulation presented in Table 1 was manufactured with continuous agitation. The materials were added to water in the following order, and subsequent materials were not added until the previous material was completely dissolved: SE, magnesium sulfate, BIG-SOFT63 N25-7 (previously melted), sodium citrate, monoethanolamine, triethanolamine, and Neolone M10. The pH was then adjusted with sodium hydroxide or sulfuric acid, as needed.
[0130] Cleaning experiments were performed in accordance with the Standard
Guide for Measuring Soil Removal from Artificially Soiled Fabrics (ASTM Designation: D 3050-07). Briefly, cleaning experiments used approximately 6Og of heavy duty liquid (HDL) added to 90° F water in a high efficiency (HE) Whirlpool Duet Sport machine on Normal setting (54 minutes full cycle). Two runs per HDL, with 4 stain cloths per run, were carried out. The experimental stain cloths employed include: DSC (dust/sebum on cotton), GC (grass on cotton), SSC (spaghetti sauce on cotton, purchased from Scientific Services, Sparrow Bush, NY), WFK-10C (wool fat kaolin on cotton, purchased from Testfabrics, West Pittston, PA) and EMPA106 (carbon black/mineral oil on cotton, purchased from Testfabrics, West Pittston, PA). Each wash also included 8 pounds of cotton, pillowcase ballast. At the end of each wash, the stain cloths were static dried and L, a, and b readings were taken on a HunterLab LabScan XE spectrophotometer, L1 a, b readings were also taken of the clean, unsoiled cotton fabric from which each stain was applied. Cleaning was then calculated by the following equation (as reported in the literature - Neiditch. O. W., et al, Journal of the American Oi! Chemist's Society. December, 1980, 426):
SRI = 10'J - \ clean " Yv awheel - (.1 , - π , < 5 - (b , - b , , where the SR! is the Stain Removal Index.
[0131] Prior to testing experimental detergent formulations that contain magnesium sulfate, the SR! values for the standard control detergent, without magnesium sulfate, were determined on DSC, GC, SSC, EMPA 106, and WFK 10C stains at pH of about 7, about 8.25. about 9.5, about 10.75. and about 12. SR! values for the control detergent without magnesium sulfate are presented in Table 2:

Results
[0133] The data presented in Tables 3-7 demonstrate that the presence of magnesium sulfate in sulfonated estolide HDL laundry formulations can improve soil removal. Magnesium ion based soil removal advantages are sensitive to stain type, pH, and MgSO4 concentration. For example, the best soil removal improvement was demonstrated at pH 7 on EMPA 106 (2% MgSO4) and WFK 1 OC (2% MgSO4), at pH 8.25 on GC (1 % MgSO4), EMPA 106 (2% MgSO4), and WFK 1 OC (2% MgSO4), at pH 9.5 on WFK 1 OC (2% MgSO4), at pH 10.75 on EMPA (1 % and 2% MgSO4) and WFK 1 OC (2% MgSO4); and at pH 12 on SSC (2% MgSO4), EMPA (1 % and 2% MgSO4). and WFK 1 OC EMPA (1 % MgSO4). In general, DSC stains were not found to be sensitive to the addition of magnesium sulfate, whiie EMPA 108 and WFK 10C stains were the easiest to remove in the presence of magnesium sulfate. Without wishing to be bound by any particular theory, it is believed that the presence of small amounts of magnesium ions in the laundry liquid improves soli removal due to the divalency of the ions that can provide the formation of larger micelles. Again, not wanting to be bound by any particular theory, it is also believed that high levels of magnesium ions in the laundry liquid may decrease soil removal by increasing soil redeposition and by decreasing the effectiveness of anionic surfactants. Therefore, the concentration of magnesium ions must be precisely controlled and tested under various conditions in order to achieve the desirable effects. Further, without wishing to be bound by any particular theory, is believed that the magnesium sulfate may react synergislicaliy with the sulfonated estolide to produce an anionic surfactant with better emulsification properties, in addition to creating bigger micelles. This may allow superior penetration into the stains and substrates. This seems particularly true with the oily, hydrophobic, and difficult to remove stains of EMPA 106 and WFK 1 OC.
EXAMPLE 2: COMPARISON OF MAGNESIUM SULFATE AND ANTI-
REDEPOSSTION POLYMERS IN SULFONATED ESTOLIDE CONTAINING HDL
LAUNDRY DETERGENT FORMULATIONS
[0134] St is well known in the art that anti-redeposition polymers (ARP) help to improve soil removal. Therefore, in this example, the results of adding magnesium sulfate to sulfonated estolide containing HDL laundry detergent was compared to results seen with addition of anti-redeposition polymers as a reference.
[0135] As described in Example 1 , detergents were tested with two different magnesium sulfate concentrations, approximately 1 % and approximately 2% weight as is. The formulations were tested over a wide pH range (pH of about 7, about 8.25, about 9.5, about 10.75, and about 12) in order to encompass formulations for economy, medium, and premium tier products. Detergents containing approximately 0.5% and approximately 1 %, (weight as is) anti-redeposition polymer were also produced and tested over the same pH range for comparison. The sulfonated estolide sample used in this example, designated SE, is the same as the sample used and described in Example 1.
[0136] The HDL compositions utilized in this example are presented in Table 8:

***Neolone M10 (C4H5NOS), Rohm and Haas, Philadelphia, PA.
[0137] The HDL formulation presented in Table 8 was manufactured with continuous agitation. The materials were added to water in the following order, and subsequent materials were not added until the previous material was completely dissolved: SE, magnesium sulfate, BIO-SOFT® N25-7 (previously melted), sodium citrate, monoethanoiamine, triethanoiamine, anti-redeposifion polymer, and Neolone 10. The pH was then adjusted with sodium hydroxide or sulfuric acid, as needed. [0138] Cleaning experiments were performed in accordance with the Standard
Guide for Measuring Soil Removal from Artificially Soiled Fabrics (ASTM Designation: D 3050-07), as described in Example 1.
[0139] Prior to testing experimental detergent formulations that contain magnesium sulfate or anti-redeposition polymers, the base line values for the STD detergent, without additives, were determined at pH of about 7, about 8.25, about 9.5, about 10.75, and about 12.

Resujts
[0141] In comparison with the addition of anti-redeposition polymer, soil removal was better for the magnesium sulfate formulations at pH 8.25 on GC (1 % MgSO4); at pH 10.75 on EMPA 106 (1 % and 2% MgSO4), and at pH 12 on EMPA 108 (1 % and 2% MgSO4) and WFK 1 OC (1 % MgSO4). Conversely, addition of the anti-redeposition polymer improved soil removal compared to the addition of magnesium sulfate at pH 7 for SSC (0.5% and 1 % ARP); at pH 8.25 for EMPA 106 (1 % ARP) and WFK 1 OC (1 % ARP); at pH 10.75 on GC (1 % ARP). In several instances, the MgSCU formulations and anti-redeposition formulations achieved similar improved soil removal results (see, for example, EMPA 106 at pH 8.25 for 2% MgSO4 and 0.5% ARP). Also, the addition of anti-redeposition polymer did not improve soil removal on any stain at pH 12. In general, DSC stains were neither sensitive to the addition of magnesium sulfate nor anti-redeposifion polymer. While the details of the magnesium sulfate and anti-redeposition polymer data are not identical, the data shows that magnesium sulfate formulations can perform as well, and sometimes better, than anti-redeposition polymers that are widely accepted and used to boost soil removal. Also magnesium sulfate is more affordable, more "green", readily available, and safe and easy to work with while some anti- redeposition polymers are expensive and considered toxic. These facts make magnesium sulfate an appealing potential additive for sulfonated estolide containing HDL laundry detergents.
EXAMPLE 3: MAGNESIUM SULFATE BASED VISOCITY DEVELOPMENT IN SULFONATED ESTOLIDE CONTAINING HDL LAUNDRY DETERGENT
FORMULATIONS
[0142] It has been observed that sulfonated estolide containing HDL laundry detergent formulations do not develop viscosity with the addition of typical inorganic salts, such as sodium chloride. However, it has been unexpectedly discovered that the HDL formulation presented in Example 1 exhibits slightly increased viscosity when magnesium sulfate is present in the formulation at pH 10 (see Table 14, 0.25% MgSO4). Therefore, addition of magnesium ions to the presently described laundry detergent formulations may be useful for viscosity adjustment.
[0143] Viscosity measurements were collected at 25° C using a RV type
Brookfield Viscometer model DV-1 1 with spindle RVT-Q2 at a speed 50 rpm. Viscosity results are presented in Table 14:
