Abstract
Detergent surfactant combinations comprising alkylpolyglycoside detergent surfactants and nonionic detergent surfactants provide good detergency and are compatible with anionic optical brighteners, both in built and unbuilt detergent compositions.
Description
This invention relates to surfactant combinations uhich provide good detergency and, optionally, good fluorescer effectiveness and/or suds control and/or corrosion inhibition in a laundry context. Such compositions can be either built or unbuilt, granular or liquid, and can contain the usual auxiliary ingredients common to such compositions.
Alkylpolyglycosides which are surfactants have been disclosed in U.S. Patents 3,598,865? 3,721,633; and
3,772,269. These patents also disclose processes for making alkylpolyglycoside surfactants and built liquid detergent compositions containing these surfactants.
U.S. Patent 3,219,656 discloses alkylmonoglueosides and suggests their utility as foam stabilizers for other surfactants. Various polyglyeoside surfactant structures and processes for making them are disclosed in U.S.
Patents 2,974,134; 3,640,998; 3,839,318; 3,314,936? 3,346,558; 4,011,389? and 4,223,129.
All percentages, parts and ratios used herein are by weight unless otherwise specified.
This invention relates to the discovery of certain combinations of surfactants which provide unusually good detergency, especially in cool water, for a variety of fabric types. Specifically this invention relates to detergent compositions comprising;
(A) from 1% to 90% of an alkylpolysaccharide detergent surfactant of the formula RO(R'O)y(Ζ)χ where R is an alkyl, alkyl phenyl, alkyl benzyl, or mixtures thereof, said alkyl groups containing from 8 to 18 carbon atoms, being either saturated or unsaturated, and containing from 0 to 3 hydroxy groups, where each R' is an ethylene, propylene or -CH2~CH(OH)-CH2- group, and y is from 0 to 12? and where each Z is a
SS300 moiety derived from a reducing saccharide containing 5 or 6 carbon atoms, and x is a number from 1.5 to 10;
(B) from 1% to 90% by weight of a nonionic detergent surfactant;
(C) from 0% to 90% by weight of a detergency builder; and (D) from 0.01% to 2% by weight of an anionic optical brightener, the ratio of A to B being from 1:10 to 10:1.
A special advantage of the combination of detergent surfactants herein is their superior compatibility with anionic fluorescent or optical brighteners. Nonionic surfactants, especially ethoxylated nonionic detergent surfactants, normally diminish the effectiveness of such brighteners. With the addition of the alkylpolyglycoeide surfactant, the brightener effectiveness is dramatically improved, especially on cotton.
The Alkvlpolysaccharide Surfactant
It has surprisingly been found that the cosurfactants interact with the alkylpolysaccharide surfactant of this invention to provide good laundry detergency for a wide range of fabrics. The alkylpolysaccharides are those having a hydrophobic group containing from 6 to 30 carbon atoms, preferably from 10 to 16 carbon atoms and a polysaccharide, e.g., a polyglycoside, hydrophilic group containing from 1¾-to 10, preferably from 1¾ to 3, most preferably from 1.6 to 2.7 saccharide units. Any reducing saccharide containing 5 or 6 carbon atoms can be used, e.g. glucose, galactose and galactosyl moieties can substitute for the glucosyl moieties. (Optionally the hydrophobic group is attached at the 2, 3, 4 etc. positions thus giving a glucose or galactose as opposed to a glucoside or galactoside.) The intersaccharide bonds can be, e.g., between the one position of the additional saccharide units
2800 and the 2-, 3-, 4-, and/or 6 positions on the preceding saccharide units.
Optionally, and less desirably, there can be a potyatkoxide chain joining the hydrophobic moiety and the polysaccharide moiety. The preferred alkoxide is ethylene oxide. Typical hydrophobic groups include alkyl groups, either saturated or unsaturated, branched or unbranched containing from 8 to 18, preferably from 10 to 16 carbon atoms. Preferably, the alkyl group is a straight chain saturated alkyl group. The alkyl group can contain up to 3 hydroxy groups and/or the polyalkoxide chain can contain up to 10, preferably less than 5, most preferably 0, alkoxide moieties. Suitable alkyl polysaccharides are octyl, nonyldecyl, undecyldodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, and octadecyl, di-, tri-, tetra-, penta-, and hexaglucosides, galactosides, lactosides, and/or fructosides. Suitable alkyl monosaccharides are octyl, nonyldecyl, undecyldodecyl, tridecyl, feetradecyl, pentadecyl, hexadecyl, heptadecyl, and octadecyl, glucoses, fructoses and/or galactoses.
Suitable mixtures include coconut alkyl, di-, tri-, tetra-, and pentaglucosides and tallow alkyl tetra-, penta-, and hexaglucosides.
The preferred alkylpolyglycosides have the formula R’01c„Hj„0)y|glycsyl)).
wherein ΪΓ is selected from alkyl, alkylphenyl, hydroxyalkyl, nydroxyalky lphenyl. and mixtures thereof in which said alkyl groups contain from 10 to 18, preferably from 12' to 14 carbon atoms; n is-2 or 3, preferably 2; y is from 0 to 10, preferably 0 ; and x is from li to 10, preferably from 1¾ to 3, most preferably from 1.6 to 2.7. The glycosyi is preferably derived from glucose. To prepare compounds the alcohol or alkylpolyethoxy alcohol is formed first and then reacted with glucose, or a source of glucose, to form the glucoside (attachment at the 1-position). The additional glycosyi units are attached between their 1-position and the preceding glycosyi units
2-, 3-. 4- and/or 6- position, preferably predominately the 2-position.
Preferably the content of alkylmonoglycoside is low, preferably less than 60%, more preferably less than 50%.
Surprisingly, anionic fluorescers which are normally relatively ineffective in the presence of conventional ethoxylated nonionic detergent surfactants at high levels in the absence of substantial levels of anionic detergent surfactants, are very effective when the alkylpolyglycoside surfactants are present.
For brightener effectiveness, the ratio of alkylpolyglycoside detergent surfactant to nonionic detergent surfactant should be greater than 1:4 preferably greater than 1:3, most preferably greater than 1:1.
THE NONIONIC DETERGENT SURFACTANT
Nonionic Surfactant
Nonionic surfactants, including those having an HLB of from 5 to 17, are well known in the detergency art. They are included in the compositions of the present invention together with the, e.g,, alkylpolyglycoside surfactants defined hereinbefore. They may be used singly or in combination with one or more of the preferred alcohol ethoxylate nonionic surfactants, described below, to form nonionic surfactant mixtures useful in combination with the alkylpolyglycosides. Examples of such surfactants are listed in U.S. Pat. No. 3,717,630, Booth, issued Feb. 20, 1973, and U.S. Pat. No. 3,332,880, Kessler etal, issued July 25, 1967. Nonlimiting examples of suitable nonionic surfactants which may be used in the present invention are as follows:
(I) The polyethylene oxide condensates of alkyl phenols.
These compounds include the condensation products of alkyl phenols having an alkyl group containing from 6 to 12 carbon atoms in either a straight chain or branched chain configuration with ethylene oxide, said ethylene oxide being present in an amount equal to 5 to 25 moles of ethylene oxide per mole of alkyl phenol. The alkyl substituent in such compounds can be derived, for example, from polymerized propylene and diisobutylene. Examples of comppunds of this type include nonyl phenol condensed with 9.5 moles of ethylene oxide per mote of nonyl phenol; dodecylphenol condensed with 12 moles of ethylene oxide per mole of phenol; dinonyl phenol condensed with 15 moles of ethylene oxide per mole of phenol; and diiso5 octyl phenol condensed with 15 moles of ethylene oxide per mole of phenol. Commercially available nonionic surfactants of this type include Igepal CO-630, marketed by the GAF Corporation, and Triton X-45, X—114, X-100, and X-102, all marketed by the Rohm & Haas Company.
(2) The condensation -nroducts of aliphatic alcohols with from 1 to 25 moles of ethylene oxide. The alkyl chain of the aliphatic alcohol can either be straight or branched, primary or secondary, and generally contains from 8 to 22 carbon atoms. Examples of such ethoxylated alcohols include the condensation product of myristyl alcohol condensed with
IO moles of ethylene oxide per mole of alcohol; and the condensation product of 3 moles of ethylene oxide with coconut alcohol (a mixture of fatty alcohols with alkyl chains varying in length from IO to I4 carbon atoms). Examples of commercially available nonionic surfactants in this type include Tergitoi I5-S-9, marketed by Union Carbide Corporation, Neodol 45-9, Neodol 23-6,5, Neodol 45-7, and Neodol 45-4, marketed by Shell Chemical Company, and Kyro EOB, marketed by The Procter & Gamble Company.
(3) The condensation products of ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol. The hydrophobic portion of these compounds has a molecular weight of from 1500 to 1800 and exhibits water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content 'is 50% of the total weight of the condensation product, which corresponds to condensation with up to 40 moles of ethylene oxide. Examples of compounds of this type include certain of the commercially available Pluronic surfactants, marketed by Wyandotte Chemical Corporation.
14) The condensation products of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylenediamine. The hydrophobic moiety of these products consists of the reaction product of ethylenediamine and excess propylene oxide, said moiety having a molecular weight of from 2500 to 3000. This hydrophobic moiety is condensed with ethylene oxide to the extent that the condensation product contains from 40% to 80% by weight of polyoxyethylene and has a molecular weight of from 5,000 to 11,000. Examples of this type of nonionic surfactant include certain of the commercially available Tetronic compounds, marketed by Wyandotte Chemical Corporation.
(5) Semi-polar nonionic detergent surfactants include water-soluble amine oxides containing one alkyl moiety of from 10 to 18 carbon atoms and 2 moieties selected from alkyl groups and hydroxyalkyl groups containing from 1 to 3 carbon atoms; water-soluble phosphine oxides containing one alkyl moiety of 10 to 18 carbon atoms and 2 moieties selected from alkyl groups and hydroxyalkyl groups containing from 1 to 3 carbon atoms; and water-soluble sulfoxides containing one alkyl moiety of from 10 to 18 caxbcn atoms and a moiety selected frcm alkyl and hydroxyalkyl moieties of from 1 to 3 carbon atoms.

In addition to the detergent surfactants described hereinbefore, the detergent compositions herein can contain from 1% to 15%, preferably from 2% to 8%, of an organic surfactant selected from anionic, zwitterionic, ampholytic, and cationic surfactants, and mixtures thereof. Surfactants useful herein are listed in U.S. Pat.

The following are representative examples of surfactants useful in the present compositions.
Water-soluble salts of the higher fatty acids, i.e., soaps, are useful anionic surfactants in the compositions herein. This includes alkali metal soaps such as the sodium, potassium, ammonium, and alkylolammonium salts of higher fatty acids containing from 8- to 24 carbon atoms, and preferably from
53S 00 to 18 carbon atoms. Soaps can be made by direct saponification of fats and oils or by the neutralization of free fatty acids. Particularly useful are the sodium and potassium salts of the mixtures of fatty acids derived from coconut oil and tallow,
i.e., sodium or potassium tallow and coconut soap. The preferred soap, as discussed hereinbefore and hereinafter, especially in combination with semipolar or amide nonionic detergent surfactants, is at least partially unsaturated.
The unsaturated fatty acid soap of this invention contains 10 from 16 to 22 carbon atoms, preferably in a straight chain configuration. Preferably the number of carbon atoms in the unsaturated fatty acid soap is from 16 to 18.
The unsaturated soap, in common with other anionic detergent and other anionic materials in the detergent compositions of this invention, has a cation which renders the soap water-soluble and/or dispersible. Suitable cations include, e.g. sodium, potassium, ammonium, monoethanolammonium, diethanolamonluni, triethanolammonium and tetramethylaimcnium cations. Sodium ions are preferred although in liquid formulations ammonium, and triethanolammonium cations are useful.
A level of at least 1% of the unsaturated fatty acid soap is desirable to provide a noticeable reduction in sudsing and corrosion. Preferred levels of unsaturated fatty acid soap are fran 1% to 15%, preferably fran 1% to 10% most preferably from 2% to 5%. The unsaturated fatty add soap is preferably present at a level that will provide a level of from 15 ppm to 200 ppm, preferably from ppm to 125 ppm in the .-. wash solution at recommended U.S. usage levels and from 30 ppm to 1000 ppm, preferably from 50 ppm to 500 ppm for
European usage levels.
Mono-, di-, and triunsaturated fatty acids are all essentially equivalent so it is preferred to use mostly monounsaturated soaps to minimize the risk of rancidity. Suitable sources of unsaturated fatty acids are well known. For example, see Bailey's Industrial Oil and Fat Products, Third Edition, Swern, published by interscience Publisher (1954).
Preferably, the level of saturated soaps is kept as low as possible, preferably less than 60%, preferably less than 50% of the total soap is saturated soap. However, low levels of saturated soaps can be used. Tallow and palm oil soaps can be used.
Useful synthetic anionic surfactants also include the watersoluble salts, preferably the alkali metal, ammonium and alkylol- ammonium salts, of organic sulfuric reaction products having in their molecular structure an alkyl group containing from 10 to 20 carbon atoms and a sulfonic acid or sulfuric acid ester group.
Such synthetic anionic detergent surfactants are desirable additives at a level of from 1% to 10% to increase the overall detergency effect and, if desired, increase the level of suds. (Included in the term alkyl is the alkyl portion of acyl groups.) Examples of this group of synthetic surfactants are the sodium and potassium alkyl sulfates, especially those obtained by sulfating the higher alcohols (Cg-C(g carbon atoms) such as those produced by reducing the glycerides of tallow or coconut oil; and the sodium and potassium alkylbenzene sulfonates in which the alkyl group contains from 9 to 15 carbon atoms, in straight chain or branched chain configuration, e.g., those of the type described in U.S. Pats. 2,220,099 and 2,477,383. Especially valuable are linear straight chain alkylbenzene sulfonates in which the average number of carbon atoms in the alkyl group ' is from 11 to 13,abbreviated as C|j_|3LAS.
