Description

WHITENING COMPOSITIONS WITH PERFUTIBLE FIELD OF THE INVENTION The invention relates to bleaching compositions with perfume. More specifically, it relates to bleaching compositions comprising a hydrophobic bleaching system and a stabilized perfume composition.
BACKGROUND OF THE INVENTION Perfumes are an important and desirable part of detergent compositions. They are used to cover the chemical odors of cleaning ingredients and provide an aesthetic benefit to the washing process, preferably clean fabrics. EP 430315, which describes the use of a laundry detergent composition containing a lipase and a perfume having specific fragrance materials, exemplifies said use. In said patent, the perfume composition counteracts the problem of residual malodor of the laundry treated with lipase. A problem encountered with perfumes is their volatility and many perfume ingredients can be destroyed or damaged in the presence of cleaning ingredients, especially alkali and bleaches. Hydrophobic bleach systems selected from a source of hydrogen peroxide combined with a hydrophobic peroxyacid bleach precursor and a hydrophobic peroxy acid bleach are known in the art as effective dark soil removal agents. The Applicants have discovered that the problem of perfume oxidation may be particularly concerning with the hydrophobic peroxyacid bleach precursors which in the perhydrolysis produce a peroxyacid which is an amino substituted peroxyacid. It has also been discovered that the precursor compounds as well as the peroxyacid compounds by themselves of the substituted amino type, in particular, give rise to the problem. A solution to this problem is the encapsulation of the perfume. This increases the expense and complexity of the formulation and does not always provide sufficient protection. EP 332259 teaches the use of a liquid detergent composition containing peroxyacid bleach and perfume silica particles that protect the oxidation perfume by the bleach. Another solution to this problem is the reduction in the level of the hydrophobic bleaching system. While reducing the level of the hydrophobic bleaching system used in washing, tends to solve these problems, this is accompanied by a marked negative effect on the ability to remove dark stains / dirt. In this way, the detergent formulator meets the challenge of formulating a product that maximizes the removal of stain / dirt, which prevents the degradation of the detergent components, which covers the chemical odors of the cleaning ingredients, that provides an aesthetic benefit and that is also inexpensive. The Applicants have now surprisingly found that the provision of a minimum amount of specific perfume materials allows the use of stabilized perfume compositions in the presence of a hydrophobic bleaching system. The Applicants have also surprisingly discovered that the assortment of the perfume in the fabric improves with the hydrophobic peroxyacid precursor. Without being limited to theory, it is believed that the hydrophobic peroxyacid precursor serves as a carrier material for the perfume composition. Therefore, an object of the present invention is to provide compositions suitable for use in laundry washing methods that produce an excellent fragrance of perfume in the fabrics as well as an excellent perfume stability in the presence of the hydrophobic bleaching system in the liquid of washing and in the product during storage. Another object of the invention is to provide compositions suitable for use in laundry washing methods that produce effective dark dirt removal.

Detergency builders Builders may optionally be included in the compositions herein to help control the hardness of minerals. Inorganic and organic detergent builders can be used. Builders are typically used in fabric washing compositions to help remove particulate soils. The level of builder can vary widely depending on the final use of the composition and its desired physical form. Granulated formulations typically comprise from 10% to 80%, very typically from 15% to 50% by weight of the builder. Nevertheless, lower or higher detergency builder levels are not excluded. Inorganic or phosphate-containing builders include, but are not limited to, the alkali metal, ammonium and alkanolaronium salts of poly phosphates (illustrated by the vitreous polymeric tripolyphosphites, pyrophosphates and metaphosphates). Non-phosphate builders can also be used. These may include, but are not restricted to, phytic acid, silicates, alkali metal carbonates (including bicarbonates and sesquicarbonates), sulfates, alu inosilicates, monomeric polycarboxylates, homo or copolymeric polycarboxylic acids or their salts in which the polymeric acid consists of at least two radicals separated from each other by no more than two carbon atoms, organic phosphonates and poly (alkylene phosphonates) of aminoalkylene. Importantly, the compositions herein work surprisingly well even in the presence of so-called "weak" detergency builders (as compared to phosphate builders) such as citrates, or in the so-called "lower detergency enhancement" situation that It can occur with zeolite builders or stratified silicate. Examples of silicate builders are the so-called "amorphous" alkali metal silicates, particularly those having a Si 2: Na 2 ratio. in the scale from 1.6: 1 to 3.2: 1 and layered silicates, such as the layered sodium silicates described in US Pat. No. 4,664,839. NaSKS-6 is the trade name for a crystalline layered silicate sold by Hoechst (commonly abbreviated as "SKS-6"). Unlike the zeolite builders, the builder of 1 NaSKS-6 silicate detergency does not contain aluminum. NaSKS-6 has the morphological form of delta-Na2Si0s of stratified silicate. It can be prepared by methods such as those described in German Application DE-A-3,417,649 and DE-A-3,742,043. SKS-6 is a highly preferred layered silicate for use herein, but other layered silicates, such as those having the general formula NaMSi ?? 2x +? yH2? wherein M is sodium or hydrogen, x is a number from 1.9 to 4, preferably 2, and y is a number from 0 to 20, preferably 0 may be used herein. Some other stratified silicates from Hoechst include NaSKS-5, NaSKS-7 and NaSKS-11 as the alpha, beta and gamma forms. As indicated above, the delta-Na2Si0e (NaSKS-6) form is most preferred for use herein. Other silicates can also be used such as for example magnesium silicate, which can serve as a tightening agent in granulated formulations, as a stabilizing agent for oxygen bleaches, and as a component of foam control systems. Examples of carbonate builders are the alkali metal and alkali metal carbonates as described in German Patent Application No. 2,321,001 published November 15, 1973. Such carbonate builders act as builders to remove ions. divalent metals such as calcium and also provide alkalinity and help in the removal of dirt.
Aluminosilicate builders are useful in the present invention. Aluminosilicate builders are of great importance in most of the heavy duty granular detergent compositions currently marketed, and can also be an important detergency builder ingredient in liquid detergent formulations. The aluminosilicate builders include those that have the empirical formula: Naz [(A102) z (Si? 2) y3.xH2? where z and y are integers of at least 6, the molar ratio of z to y is on the scale of 1.0 to 0.5, and x is an integer of 15 to 264. Useful aluminosilicate ion exchange materials are commercially available. These aluminosilicates can be crystalline or amorphous in structure and can be naturally occurring or synthetically derived aluminoeilicates. A method for producing aluminosilicate ion exchange materials is described in US Patent 3,985,669. Preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. In an especially preferred embodiment, the ion exchange material of crystalline aluminosilicate has the formula: N i2 C (A102) l2 (SÍO2) l2 3. H2? wherein x is from 20 to 30, especially from 27. The material is known as Zeolite A. Dehydrated zeolites (x = 0-10) can also be used herein. Preferably, the al-rninosilicate has a particle size of about 0.1-10 microns in diameter. Organic builders suitable for the purposes of the present invention include, but are not limited to, a wide variety of polycarboxylate compounds. As used herein, "polycarboxylates" refers to compounds having a plurality of carboxylate groups, preferably at least 3 carboxylates. Polycarboxylate builders can generally be added to the composition in acid form, but can also be added in the form of a neutralized salt. When used in the salt form, alkali metals such as sodium, potassium and lithium, or alkanolammonium salts are preferred. Included among the polycarboxylate builders are a variety of useful material categories. An important category of polycarboxylate builders include ether polycarboxylates, including oxydisuccinate, as described in the U.S.A. 3,128,287 and in the U.S. Patent. 3,635,830. See also detergency builders of "TMS / TDS" of the U.S. Patent. 4,663,071. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U.S. Pat. 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903. Other useful builders include ether hydroxypolycarboxylates, maleic anhydride copolymers with ethylene or vinyl methyl ether, 1,3,5-trihydroxybenzene, 2,4,6-tris-1-phonic acid, and carboxymethyloxy-succinic acid, various alkali metal salts, ammonium and substituted ammonium of polyacetic acids such as ethylenediaminetetraacetic acid and nitrilotriacetic acid, as well as polycarboxylates such as mellitic acid, succinic acid, oxydisuccinic acid, poly-aleic acid, benzene-1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid and soluble salts thereof. Citrate builders, for example, citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty liquid detergent formulations because of their availability from renewable resources and its biodegradability. The citrates can also be used in granular compositions, especially in combination with zeolite builders and / or layered silicate. Oxydisuccinates are also especially useful in said compositions and combinations. Also suitable in the detergent compositions of the present invention are the 3,3-dicarboxy-4-oxa-1, 6-hexanodiatoe and the related compounds described in the U.S. Pat. 4,566,984. Useful succinic acid builders include the C5-C20 alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Specific examples of succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinato, 2-dodecenylsuccinate (preferred), 2-pentadecenylsuccinate, and the like. Lauryl succinates are the preferred builders of this group, and are described in EP 0,200,263. Other suitable polycarboxylates are described in the U.S. Patent. 4,144,226 and in the Patent of E.U.A. 3,308,067. See also the patent of E.U.A. 3,723,322. Fatty acids, for example, C12-C18 monocarboxylic acids, may also be incorporated into the compositions by themselves, or in combination with the aforementioned builders, especially citrate and / or succinate builders, to provide Additional detergency improvement activity. Said use of fatty acids will generally result in a decrease in foaming, which would be considered by the formulator. In situations where phosphorus-based detergency builders can be used, and especially in the bar formulations used for hand-washing operations, various alkali metal phosphates such as the well-known sodium tripolyphosphates, pyrophosphate sodium and sodium orthophosphate. Phosphonate builders such as ethane-1-hydroxy-1,1-diphe- phonate and other known phosphonates can also be used (see, for example, U.S. Patents 3,159,581, 3,213,030, 3,422,021, 3,400,148 and 3,422,137).

More preferably, if used, the chelating agents will comprise from 0.1% to 3.0% by weight of said compositions. A chelating agent can be selected from amino carboxylate, polyfunctional substituted aromatic compound, nitriloacetic acid and mixtures thereof.

Additional enzymes to be incorporated include proteases, amylases, lipases, cellulases and peroxidase, as well as mixtures thereof. Other types of enzymes can also be included. They can be of any suitable origin, such as plant, animal, bacterial, fungal and yeast origin. However, its choice is governed by several factors such as the activity of pH and / or optimum stability, terrnostability, ability to act against active detergents, detergency builders as well as its potential to cause bad odors during use. In this regard, bacterial or fungal enzymes are preferred, such as bacterial amylases and proteases and fungal cellulases.

A wide variety of enzyme materials and media p > for its incorporation into synthetic detergent compositions in the U.S. Patent. 3,553,139. Additionally, enzymes are described in the U.S. Patent. 4,101,457 and in the U.S. Patent. 4,507,219. Useful enzyme materials for liquid detergent formulations and their incorporation into such formulations are described in the U.S. Patent. 4,261,868. Enzymes for use in detergents can be stabilized by various techniques. Enzyme stabilization techniques are described and illustrated in the U.S. Patent. 3,600,319 and in European Patent Application Publication No. 0 199 405. Enzyme stabilization systems are also described, for example, in the U.S. Pat. 3,519,570.
Enzyme stabilizers The enzymes employed herein are stabilized by the presence of water soluble sources of calcium and / or magnesium ions in the final compositions that provide said ions to the enzymes. (Calcium ions are generally more effective in some way than magnesium ions and are preferred in the present if only one type of cation is being used). Additional stability can be provided by the presence of several other stabilizers described in the art, especially the borate species: see Severson, U.S. 4,537,706. Typical detergents, especially liquids, will comprise from 1 to 30, preferably from 2 to 20, more preferably from 5 to 15, and most preferred from 8 to 12, calcium ionium oxides per liter of the final composition. This may vary in some way, depending on the amount of enzyme present and its response to calcium and magnesium ions. The level of the calcium or magnesium ions should be selected so that there is always some maximum level available for the enzyme, after allowing the formation of complexes with builders, fatty acids, etc., in the composition. Any water soluble calcium or magnesium salt can be used as the source of calcium or magnesium ions, including, but not limited to, calcium chloride, calcium sulfate, calcium rnalate, calcium maleate, calcium hydroxide, calcium, and calcium acetate, and the corresponding magnesium salts. A small amount of calcium ion, generally 0.05 to 0.4 millimoles per liter, is also often present in the composition due to calcium in the enzyme suspension and water formula. In solid detergent compositions, the formulation may include a sufficient amount of a water soluble calcium ion source to supply said amounts in the wash liquor. In the alternative, the hardness of natural water may be sufficient. It should be understood that the above levels of calcium and / or magnesium ions are sufficient to provide enzyme stability. More calcium and / or magnesium ions can be added to the compositions to provide an additional measure of fat removal performance. Accordingly, as a general proposition, the compositions herein will typically comprise from 0.05% to 2% in p >, that of a water soluble source of calcium or magnesium ions, or both. Of course, the amount may vary with the amount and type of enzyme used in the composition. The compositions herein may also optionally, but preferably, contain several additional stabilizers, especially borate type stabilizers. Typically, said stabilizers will be used at levels in the compositions from 0.25% to 10%, preferably from 0.5% to 5%, more preferably from 0.75% to 3% by weight of boric acid or other borate compound capable of forming boric acid in the composition (calculated on the basis of boric acid). Boric acid is preferred, although other compounds such as boric oxide, borax and other alkali metal borates (for example, ortho-, meta- and sodium pyroborate, and sodium pentaborate) are suitable. Substituted boric acids (eg, phenylboronic acid, butan boronic acid, and p-bromo phenylboronic acid) may also be used in place of boric acid.
Polymeric dispersing agents Polymeric dispersion agents can be advantageously used at levels of 0.5% to 8%, by weight, in the compositions herein, especially in the presence of stratified silicate builders and / or zeolite. Suitable polymeric dispersing agents include polymeric polycarboxylates and polyethylene glycols, although others known in the art may be used. It is believed, although not intended to be limited by theory, that polymeric dispersion agents improve the overall performance of the detergency builder, when used in combination with other builders (including low molecular weight polycarboxylates) by inhibition of crystal growth, peptization of particle dirt release and anti-redeposition. The polymeric polycarboxylate materials can be prepared by polymerization or copolymerization of suitable unsaturated monomers, preferably in their acid form. Unsaturated monomeric acids which can be polymerized to form suitable polymeric polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citratonic acid and ethylene-aronic acid. The presence in the polymeric polycarboxylates of the present or monomeric segments, which do not contain carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc., is suitable provided that said segments do not constitute more than about 40% by weight. Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Said oligomers based on acrylic acid which are useful herein are the water soluble salts of polymerized acrylic acid. The average molecular weight of such polymers in the acid form preferably ranges from 2,000 to 10,000, most preferably from 4,000 to 7,000 and most preferably even from 4,000 to 5,000.

The use of polyacrylates of this type in detergent compositions has been described, for example, in Diehl, U.S. Pat. No. 3,308,067, issued March 7, 1967. Acrylic / maleic-based copolymers can also be used as a preferred component of the dispersing / anti-redeposition agent. Such materials include water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight of said copolymers in the acid form preferably ranges from 2,000 to 100,000, most preferably from 5,000 to 75,000, most preferably even from 7,000 to 65,000. The ratio of acrylate to maleate segments in said copolymers will generally vary from 30: 1 to 1: 1, preferably, from 10: 1 to 2: 1. The water-soluble salts of said acrylic acid / maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate / rnaleate copolymers of this type are known materials which are described in European Patent Application No. 66915 published on December 15, 1982, as well as in EP 193,360, published on September 3, 1986, which describe also said polymers consisting of hydroxypropylacrylate. Still other useful agents include the maleic / acrylic / vinyl alcohol terpolymers. Such materials are also described in EP 193,360, including, for example, the 45/45/10 terpolymer of acrylic / maleic / vinyl alcohol. Another polymeric material that can be included is polyethylene glycol (PEG). The PEG can exhibit performance of dispersing agent, as well as acting as a remover and anti-deposition of clay dirt. Typical molecular weight scales for these purposes vary from 500 to 100,000, preferably from 1,000 to 50,000, most preferably from 1,500 to 10,000. The dispersing agents of polyaspartate and polyglutamate can also be used, especially together with the zeolite builders. Dispersing agents such as polyaspartate preferably have a molecular weight (avg.) Of 10,000.

Polymeric dirt-releasing agents are characterized in that they have both polymeric segments, to make the surface of the hydrophobic fibers, such as polyester and nylon, hydrophilic, as hydrophobic segments, to be deposited on the hydrophobic fibers and to remain adhered thereto until the termination of the hydrophobic fibers. washing and rinsing cycles and, thus, serve as an anchor for the hydrophilic segments. This allows stains that occur after treatment with the soil release agent to be more easily cleaned in subsequent washing procedures. Dirt release agents characterized by hydrophobic segments of poly (vinyl ester) include graft copolymers of vinyl polyester), for example vinyl ester of C? ~ Cß, preferably poly (vinyl acetate) grafted onto polyalkylene oxide base structures such as polyethylene oxide base structures.

Sodium lonato.
Said soil release agent also comprises from 0.5% to 20% by weight of the oligomer of a reducing-crystalline stabilizer, preferably selected from the group consisting of xylene sulfonate, only eutene fonate, toluene sulfonate and mixtures thereof.

The detergent compositions herein may also optionally contain from 0.005% to 5% by weight of certain types of hydrophilic optical brighteners that also provide a dye transfer inhibiting action. If used, the compositions herein will preferably comprise from 0.01% to 1.2% by weight of said optical brighteners. The hydrophilic optical brighteners useful in the present invention are those having the structural formula: wherein Ri is selected from anilino, N-2-bis-hydroxyethyl and NH-2-hydroxyethyl; R 2 is selected from N-2-bis-hydroxyethyl, N-2-hydroxyethyl-N-methylamino, morphino, chloro and amino; and M is a salt-forming cation such as sodium or potassium. When in the above formula, Ri is anilino, R2 is N-2-bis-hydroxyethyl and M ee a cation such as sodium, the brightener is 4,4 'acid, bisC (4-anilino-6- (N-2- bis-hydroxyethyl) -s-triazin-2-yl) amino] -2, 2'-styrylisulfonic acid and disodium salt. This particular brightener species is marketed under the trade name Tinopal-UNPA-GXR by Ciba-Geigy Corporation. Tinopal-UNPA-GX is the preferred hydrophilic optical brightener useful in the detergent compositions of the present invention. When in the above formula R1 is anilino, R2 is N-2-hydroxyethyl-N-2-methylamino and M is such a cation or sodium, the brightener is the disodium salt of 4,4'-bis [4] -anilino-6- (N-2-hydroxyethyl-N-methylamino) -s-triazin-2-i1) ami or 1 -2,2'-stilbenedisulfonic acid. This particular brightener species is commercially marketed under the trade name Tinopal 5BM-GXR by Ciba-Geigy Corporation. When in the above formula R1 is anilino, R2 is oryphine and M is a cation such as sodium, the brightener is the sodium salt of 4,4'-bisC (4-anilino-6-morphino-s-triazin- 2-yl) arnino32,2 '-stilbenedisulfonic. This particular kind of brightener is sold commercially under the trade name Tinopal AMS-GX by Ciba-Geigy Corporation. The specific optical brightener species selected for use in the present invention provide performance benefits of dye transfer inhibition especially effective when used in combination with the selected polymeric dye transfer inhibitor agents described above. The combination of said selected polymeric materials (e.g., PVNO and / or PVPVI) with said selected optical brighteners (e.g., Tinopal UNPA-GX, Tinopal 5BM-GX and / or Tinopal AMS-GX) provides significant dye transfer inhibition. better in aqueous washing solutions than either of those two components of detergent composition when used alone. Without being limited to the theory, it is believed that such brighteners work in this way because they have high affinity for fabrics in the wash solution and therefore they deposit relatively quickly on these fabrics. The degree to which the brighteners are deposited on the fabrics in the washing solution can be defined by a parameter called "depletion coefficient". The depletion coefficient is in general the ratio of a) the polishing material deposited on the cloth to b) the initial polish concentration in the wash liquor. Brighteners with relatively high depletion coefficients are most suitable for inhibiting dye transfer in the context of the present invention. Of course, it will be appreciated that the other types of conventional optical brightener compounds may optionally be used in the compositions herein to provide conventional "brightness" benefits to the fabrics, rather than a true dye transfer inhibiting effect. Said use is conventional and well known for detergent formulations. Any optical brighteners or brightening or whitening agents known in the art can be incorporated at typically 0.05% to 1.2% by weight, in the detergent compositions herein. Commercial optical brighteners that may be useful in the present invention can be classified into subgroups, including, but not necessarily limited to, stilbene, pyrazoline, c? arina, carboxylic acid, methinocyaninae, 5,5-dibenzothiophene dioxide, azolee, 5 and 6 membered ring heterocyclics, and various other agents.

This suppression of foams can be of particular importance in the so-called "high concentration cleaning procedure" and in front-loading European style washing machines. A wide variety of materials can be used as suds suppressors, and the foam pressors are well known to those skilled in the art. See, for example, Kirk Othmer Encyclopedia of Chemical Technology, 3rd Edition, Volume 7, pages 430-447 (John Uiley a Sons, Inc., 1979). A category of foam pressers of particular interest comprises rnonocarbonate fatty acid and soluble salts therein. See Patent of E.U.A. 2,954,347. The monocarboxylic fatty acids and salts thereof used as foam suppressors typically have hydrocarbyl chains of 10 to 24 carbon atoms, preferably 12 to 18 carbon atoms. Suitable salts include the alkali metal salts such as sodium, potassium and lithium salts, as well as ammonium and alkanolammonium salts. Lae detergent compositions herein may also contain non-surfactant suppressants. These include, for example, high molecular weight hydrocarbons such as paraffin, fatty acid esters (eg, fatty acid triglycerides), fatty acid esters of monovalent alcohols, aliphatic ketones of (eg, stearone), etc. Other foam inhibitors include N-alkylated amino triazines such as tri- to hexa-alkylmelamines or di- to tetra-alkyldiarninochlorothiazines formed as cyanuric chloride products with two or three F? moles of primary or secondary amide containing from 1 to 24 carbon atoms, propylene oxide and rnonostearyl phosphates such as monostearyl alcohol phosphate ester and alkali metal di-metal phosphate mono-ester phosphates (eg, K, Na) , and Li). Hydrocarbons such as paraffin and halogenoparaffin can be used in liquid form. The liquid hydrocarbons will be liquid at room temperature and at atmospheric pressure and will have a pour point on the scale of approximately -40 ° C and approximately 50 ° C and a minimum boiling point not less than approximately 110 ° C (atmospheric pressure). The use of waxy hydrocarbons is also known, preferably having a melting point less than about 100 ° C. Hydrocarbons constitute a preferred category of foam suppressors for detergent compositions. The hydrocarbon foam suppressors are described, for example, in the U.S. Patent. No. 4,265,779. The hydrocarbons, therefore, include aliphatic, alicyclic, aromatic and saturated or unsaturated heterocyclic hydrocarbons having from 12 to 70 carbon atoms. The term "paraffin" as used in this description of eep? Mae supresoree is intended to include mixtures of p > true fines and cyclic hydrocarbons. Another preferred category of non-surfactant foam suppressors comprises silicone foam suppressors. This category includes the use of polyorgano siloxane oils, such as polydimethyl siloxane, oil dispersions or emulsions and the polyorganosiloxane or resins, and combinations of polyorganosiloxane with silica particles wherein the polyorganosiloxane is absorbed or fused onto the silica. Silicone foam suppressors are well known in the art and for example are described in the U.S. Patent. 4,265,779 and EP 354016. Other precursors of silicone foams are described in the patent of E.U.A. No. 3,455,839, which relates to compositions and methods for removing foams from aqueous solutions by incorporating in them small amounts of polydi-ethylsiloxane fluids. Mixtures of silicone and silanated silica are described, for example, in the German Patent Application DOS 2, 124,526. Silicone foam scavengers and foam controlling agents in granular detergent compositions are set forth in US Pat. 3,933,672 and in the U.S. Patent. 4,652,392. An illustrative silicone-based foamer eupressor for use herein is a foaming agent suppressing amount of foaming agent consisting essentially of: (i) polydimethisiloxane fluid having a viscosity of 20 cs at 1,500 cs at 25 ° C. (ii) from 5 to 50 parts per 100 parts by weight of (i) siloxane resin composed of units (CH3Í3 SiO? / 2 SiO2 units in a ratio of units of (CH3 3 SÍO1 / 2 to units of SÍO2 of 0.6 : 1 to 1.2: 1; and (iii) from 1 to 20 parts per 100 parts by weight of (i) of a silica gel. In the preferred silicone foam suppressant used herein, the solvent for a continuous phase is formed of certain polyethylene glycols or polyethylene-polypropylene glycol copolymers or mixtures thereof (preferred), or polypropylene glycol. The eupressor of primary silicone foams is branched / interlaced and preferably non-linear. To further illustrate this point, typical liquid laundry detergent compositions with optionally controlled foam will comprise from 0.001 to 1, preferably from 0.01 to 0.7, preferably from 0.05 to 0.5, weight percent of said silicone foam suppressant, which comprises (1) a non-aqueous emulsion of a primary anti-foam agent which is a mixture of (a) a polyorganosiloxane, (b) a resin siloxane or a silicone compound that produces silicone resin, (c) a finely filler material divided, and (d) a catalyst for promoting the reaction of the mixture components (a), (b) and (c), to form silanolates; (2) at least a nonionic silicone surfactant; and (3) polyethylene glycol or polyethylene-polypropylene glycol copolymer having a solubility in water at room temperature of more than 2% by weight; and without polypropylene glycol.
Similar amounts can be used in granular compositions, gels, etc. See also Patents of E.U.A. 4,978,471 and 4,983,316; 5,288,431 and Patents of E.U.A. 4,639,489 and 4,749,740, Aizawa et al. In column 1, line 46 to column 4, line 35. The silicone foam pressor herein preferably comprises polyethylene glycol and a copolymer of polyethylene glycol / polypropylene glycol, which they have an average molecular weight of less than 1,000, preferably between 100 and 800. The polyethylene glycol and polyethylene / polypropylene copolymers herein have a solubility in water at room temperature of more than 2% by weight, preferably more than 5% by weight. % in weigh. The preferred solvent herein is polyethylene glycol having an average molecular weight of less than 1,000, more preferably between 100 and 800, most preferred between 200 and 400, and a copolymer of polyethylene glycol / polypropylene glycol, preferably PPG 200 / PEG 300. Preferred is a ratio in p > that of between 1: 1 and 1:10, most preferred between 1: 3 and 1: 6, of polyethylene glycol: polyethylene-polypropylene glycol copolymer. The preferred silicone foam suppressors used herein do not contain polypropylene glycol, particularly 4,000 molecular weight. They also preferably do not contain block copolymers of ethylene oxide and propylene oxide, such as PLURONIC L101.
Other foam suppressants useful herein include secondary alcohols (eg, 2-alkylene alkanols) and mixtures of said alcohols with silicone oils, such as siliconee described in U.S. 4,798,679, 4,075,118 and EP 150,872. Secondary alcohols include the alkyl alcohols of Cß-Ciß having a chain of Ci-Ciß-A preferred alcohol is octanol of 2-butyl, which is available by Condea under the brand ISOFOL 12. Mixtures of secondary alcohols are available under the trademark ISALCHEM 123 of Enichern. The mixed foam suppressors typically comprise mixtures of alcohol + silicone at a weight ratio of 1: 5 to 5: 1. For any detergent composition to be used in automatic laundry washing machines, the foams should not be formed to the extent that they protrude from the washing machine. The foam suppressors, when used, are preferably present in a "foam suppression amount". By "foam suppression amount" is meant that the formulator of the composition can select an amount of this foam controlling agent that will sufficiently control to result in a low sputtering laundry detergent for use in automatic laundry washing machines . The compositions herein will generally comprise from 0% to 5% of additional foam suppressors. When used as suds suppressors, the monocarboxylic fatty acids, and salts therein, will typically be present in amounts up to 5%, by weight, of the detergent composition. Preferably, 0.5% to 3% of fatty monocarboxylate foam suppressant is used. Silicone foam suppressors are typically used in amounts up to 2.0%, by weight, of the detergent composition, although larger amounts may be used. This upper limit is practical in nature, mainly due to the interest of keeping costs reduced to the minimum and effectiveness of lower quantities to effectively control foaming. Preferably 0.01% to 1% silicone foam suppressant is used, more preferably 0.25% to 0.5%. As used herein, these weight percent values include any silica that may be used in combination with polyorganosiloxane, as well as any adjunct material that may be used. The rnonostearyl phosphate foam suppressors are generally used in amounts ranging from 0.1% to 2%, by weight, of the composition. Hydrocarbon foam suppressors are typically used in amounts ranging from 0.01% to 5.0%, although higher levels can be used. The alcohol foam suppressors are typically used at 0.2% -3% by weight of the complete compositions.
Fabric softeners Varioe fabric softeners that soften during washing, especially the impalpable smectite clays of U.S. Pat. 4,062,647, as well as other softening clays known in the art, can optionally be used typically at levels of 0.5% to 10% by weight in the present compositions to provide softening benefits concurrently with fabric cleaning. Clay-based softeners can be used in combination with amine and cationic softeners as described, for example, in US Pat. 4,375,416 and the U.S. Patent. 4,291,071.
Other ingredients A wide variety of other ingredients useful in detergent compositions can also be included in the compositions herein, including other active ingredients, vehicles, hydrothogens, processing aids, dyes or pigments, solvents for liquid formulations, solid fillers for bar compositions , etc. If high foaming is desired, foamed impellers such as Cio-Ciß alkanolamides can be incorporated into the compositions, typically at a level of 1% -10%. Cio-CIA ethanol and diethanol amides illustrate a typical class of such foam impellers. It is also advantageous to use said foam impellers with adjuvanted high-spraying surfactants such as the amine oxides, betaines and sultaines indicated above. If desired, the soluble magnesium salts such as MgCl2, MgSO *, and the like may be added at a level of, typically, 0.1% -2%, to provide additional oil and to improve the performance of fat removal. Various detersive ingredients employed in the present compositions can be further stabilized by absorbing said ingredients on a porous hydrophobic substrate, then coating said substrate with a hydrophobic coating. Preferably, the detersive ingredient is mixed with a surfactant before being absorbed into the porous substrate. During use, the detersive ingredient is released from the substrate in the aqueous wash liquor, where it performs its intended detersive function. To illustrate this technique in more detail, a porous hydrophobic silica (trade name SIPERNAT DIO, Degussa) is mixed with a proteolytic enzyme solution containing 3% -5% nonionic ethoxylated alcohol surfactant of C13-IS (EO 7 ). Typically, the enzyme / surfactant solution is 2.5X the weight of the silica. The resulting powder is dispersed with agitation in silicone oil (various viscosities of silicone oil can be used in the range of 500-12,500). The resulting silicone oil dispersion is emulsified or otherwise added to the final detergent matrix. By this means, ingredients such as the aforementioned enzymes, bleaches, bleach activators, bleach catalysts, photoactivators, dyes, fluorescers, fabric conditioners and hydrolyzable surfactants can be "protected" for use in detergents. The detergent compositions herein will preferably be formulated such that during use in aqueous cleaning operations, the wash water will have a pH of between 6.5 and 11, preferably between 7.5 and 10.5. The formulations of automatic dishwashing products preferably have? N p > H between 6.8 and 9.0. Laundry products typically have a pH of 9 to 11. Techniques for controlling pH at recommended usage levels include the use of pH, alkali, acid regulators, etc., and are well known to those skilled in the art.
Other optional ingredients Other suitable ingredients for inclusion in the compositions of the invention include perfumes, colors and filler salts, with sodium sulfate being a preferred filler salt.
Form of the compositions The detergent compositions of the invention can be formulated in any desirable form such as powders, granules, pastes, liquids and gels.
Compositions líq? Idae The detergent compositions of the present invention can be formulated as liquid detergent compositions. Such liquid detergent compositions typically comprise from 94% to 35% by weight; preferably from 90% to 40% by weight, most preferably from 80% to 50% by weight of a liquid carrier, for example, water, preferably a mixture of water and an organic solvent.
Compounds in gel The detergent compositions of the present invention may also be in the form of gels. Such compositions are typically formulated with polyalkenyl polyether having a molecular weight of from about 750,000 to 4,000,000.
Solid compositions The detergent compositions of the present invention may also be in the form of solids, such as powders and granules. The average particle size of the components of the granulated compositions according to the invention should preferably be such that no more than 5% of the particles are larger than 1.44 mm in diameter and no more than 5% of the particles are less than 0.15. m in diameter. The term "average particle size" as used in the preend, is calculated by sifting a sample of the composition in a number of fractions (typically 5 fractions) in a series of Tyler sieves. The fractions of weight thus obtained are compared against the opening size of the sieves. The average particle size is considered as the size of the aperture through which 50% by weight of the model would be paired. The overall de? Ciency of the granular detergent compositions according to the present invention is also useful in concentrated granular detergent compositions which are characterized by relatively high de? Ciency compared to conventional laundry detergent compositions. Such high density compositions typically have an overall density of at least 600 g / liter, preferably from 650 g / liter to 1200 g / liter, most preferably from 650 g / liter to 1200 g / liter and more preferably 800 g / liter. liter at 1000 g / liter. The overall density is measured by means of a simple funnel and container device consisting of a conical funnel rigidly molded on a base and provided with a flap valve at its lower end to allow the contents of the funnel to be emptied into a cylindrical container axially aligned below the funnel. The funnel is 130 m high and has internal diameters of 130 mrn and 40 mrn in its respective upper and lower extremities. It is mounted so that the lower extremity is 140 mrn on the upper surface of the base. The vessel has a total height of 90 mm, an internal height of 87 mm and an internal diameter of 84 nm. Its nominal volume is 500 ml. To carry out a measurement, the funnel is filled with a powder by manually emptying, the flap valve is opened and the powder is allowed to overflow from the container. The full container is removed from the frame and the excess powder is removed from the container by passing an implement with straight edges, for example, a knife through its upper edge. The filled container is then weighed and the value obtained for the weight of the powder is doubled to provide a global density in g / liter. Similar measurements are made as required.
