Definitions
- the present invention relates to the use of oleoyl sarcosinate in combination with various mono- and di-alkanolamidessurfactants to provide improved detersive compositions.
- Most conventional detergent compositions contain mixtures of various detersive surfactants in order to remove a wide variety of soils and stains from surfaces.
- various anionic surfactants especially the alkyl benzene sulfonates, are useful for removing particulate soils
- various nonionic surfactants such as the alkyl ethoxylates and alkylphenol ethoxylates are useful for removing greasy soils.
- mixtures of anionic and nonionic surfactants are used in many modern detergent compositions.
- nonionic surfactants which comprise the alkanolamides are well-known for use in various detergent compositions. Mainly, however, they are used at modest levels, to increase sudsing. It has now been discovered that this mild, biodegradable class of surfactants can deliver surprisingly desirable cleaning benefits when properly formulated in laundry and dishwashing compositions.
- oleoyl sarcosinate is employed as the anionic surfactant in conjunction with alkanolamide nonionic surfactants to provide improved cleaning benefits, especially with respect to greasy/oily soils and stains.
- the compositions are advantageously water-soluble over a broad range of temperatures, are easy to formulate, and would appear to have no untoward interaction with most detergency ingredients.
- Use of the combination of oleoyl sarcosinate with the alkanolamide and enzymes appears to provide superior stability and oily stain removal performance.
- the compositions provide low interfacial tensions and excellent cleaning even in non- phosphate built compositions, especially with zeolite or silicate detergency builders.
- the present invention overcomes many of the problems associated with known technologies and provides excellent detergent compositions for use in a wide variety of cleaning operations, as will be seen from the following disclosures.
- the present invention encompasses cleaning compositions which comprise:
- the alkanolamide is a member selected from the group consisting of the CIQ-18- most preferably C12-C14, fatty acid amides of monoethanolamine (preferred) and diethanolamine, and rnixtures thereof.
- such compositions comprise at least about 5%, by weight, of a mixture of said surfactants (a) and (b), and most preferably comprise from about 5% to about 45% of a mixture of surfactants (a) and (b), at a weight ratio of (a):(b) in the range from about 1:10 to about 10:1, especially from about 1:2 to about 2:1.
- Fully formulated detergent compositions herein will additionally comprise: various adjunct materials such as detergency builders; enzymes; soil release agents; dye transfer inhibitors; bleach; various other non-oleoyl sarcosinate, non- alkanolamide; detersive surfactants; dispersing agents; suds suppressors; and the like, and mixtures thereof, according to the desires of the formulator and the intended end-use of the compositions.
- the invention also encompasses a method for cleaning surfaces, especially fabrics and dishware, comprising contacting said surfaces with an aqueous medium which contains at least about 50 ppm, preferably from about 100 to about 10,000 ppm, of a composition according to the invention, preferably with agitation. All percentages, ratios and proportions herein are by weight, unless otherwise specified. All documents cited are, in relevant part, incorporated herein by reference.
- compositions comprise oleoyl sarcosinate, in its acid and/or salt form selected as desired for the compositions and uses herein, having the following formula:
- M is hydrogen or a cationic moiety.
- M are hydrogen and alkali metal salts, especially sodium and potassium.
- Oleoyl sarcosinate is commercially available, for example as Hamposyl O supplied by W. R. Grace & Co.
- Compositions according to the present invention typically comprise from about 0.5% to about 55%, preferably from about 1% to about 20%, and most preferably from about 3% to about 15%, of oleoyl sarcosinate by weight of the composition.
- oleoyl sarcosinate useful herein can also preferably be prepared from the ester
- reaction may be illustrated by the scheme:
- This salt may optionally be neutralized to form the oleoyl sarcosinate in its acid form.
- the preferred method for preparing oleoyl sarcosinate is conducted at a temperature from about 80°C to about 200°C, especially from about 120°C to about 200°C. It is preferred to conduct the reaction without solvent although alcohol solvents which have a boiling point of at least 100°C and are stable to the reaction conditions (ie. glycerol is not acceptable) can be used.
- the reaction may proceed in about 85% yield with a molar ratio of methyl ester reactant to sarcosine salt reactant to basic catalyst of about 1:1:0.05-0.2.
- Methyl ester mixtures derived from high oleic content natural oils are especially preferred as starting materials. Examples include high-oleic sunflower and rapeseed/canola oil. In addition, a high-oleic methyl ester fraction derived from either palm kernel oil or tallow is acceptable. It is to be understood that such oils typically will contain some levels of impurities, including some fatty acid impurities that may be converted to sarcosinate compounds by this synthesis method.
- commodity canola/rapeseed oil may comprise a majority of oleic acid, and a mixture of fatty acid impurities such as palmitic, stearic, linoleic, linolenic and/or eicosenoic acid, some or all of which are converted to the sarcosinate by this reaction method. If desired for formulation purposes, some or all of such impurity materials may be excluded from the starting oil before preparing the oleoyl sarcosinate to be used in the present compositions.
- sarcosine remaining in the reaction mixture can be converted to an amide by addition of maleic or acetic anhydride to the mixture, thereby minimizing the sarcosine content and any potential for formation of undesired nitrogen-containing impurities.
- oleoyl sarcosinate The synthesis of oleoyl sarcosinate may be carried out as follows to prepare the sodium oleoyl sarcosinate.
- reaction mixture is heated to 170°C for 1 hr to drive off any water.
- the reaction is initiated by the addition of sodium methoxide 25% in methanol (15.4 g, 0.0714 mol). Reaction is kept at 170°C for 2.5 hr during which methanol is collected in the Dean-Stark trap. The reaction is allowed to cool slightly and then methanol (200 g) is added. Maleic anhydride (9.43 g, 0.095 mol) is added to the methanol solution and the reaction is stirred at 60°C for 0.5 hr. Then most of the methanol is removed by rotary evaporation and acetone (2 L) is added to precipitate the product.
- the product is collected by suction filtration and allowed to air dry to give an off-white solid. Analysis of the reaction mixture by GC indicates the majority of the product is oleoyl sarcosinate, with minor amounts of the following impurities: sarcosine, oleic acid, and the sarcosinates derived from palmitic acid, stearic acid, and linoleic acid. Alkanolamides:
- alkanolamides used herein are of the general formula
- R is C9-C17 alkyl or alkenyl
- Y is monohydroxy alkylene, e.g.,
- the alkanolamides will comprise at least about 3%, preferably from about 5% to about 20%, by weight of the present compositions.
- adjunct ingredients may be used in combination with the oleoyl sarcosinate and alkanolamide surfactants herein to provide fully- formulated cleaning compositions of various types.
- the following ingredients are described for the convenience of the formulator, but are not intended to be limiting.
- Builders - Detergent builders can optionally be included in the compositions herein to assist in controlling mineral hardness. Inorganic as well as organic builders can be used. Builders are typically used in fabric laundering compositions to assist in the removal of paniculate soils.
- the level of builder can vary widely depending upon the end use of the composition and its desired physical form. When present, the compositions will typically comprise at least about 1% builder. Liquid formulations typically comprise from about 5% to about 50%, more typically about 5% to about 30%, by weight, of detergent builder. Granular formulations typically comprise from about 10% to about 80%, more typically from about 15% to about 50% by weight, of the detergent builder. Lower or higher levels of builder, however, are not meant to be excluded.
- Inorganic or P-containing detergent builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta-phosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulphates, and aluminosilicates.
- non-phosphate builders are required in some locales.
- compositions herein function surprisingly well even in the presence of the so-called “weak” builders (as compared with phosphates) such as citrate, or in the so-called “underbuilt” situation that may occur with zeolite or layered silicate builders.
- silicate builders are the alkali metal silicates, particularly those having a Si ⁇ 2:Na2 ⁇ ratio in the range 1.0:1 to 3.2:1 and layered silicates, such as the layered sodium silicates described in U.S. Patent 4,664,839, issued May 12, 1987 to H. P. Rieck.
- NaSKS-6 is the trademark for a crystalline layered silicate marketed by Hoechst (commonly abbreviated herein as "SKS- 6").
- Hoechst commonly abbreviated herein as "SKS- 6"
- the Na SKS-6 silicate builder does not contain aluminum.
- NaSKS-6 has the delta-Na2SiO5 morphology form of layered silicate.
- SKS-6 is a highly preferred layered silicate for use herein, but other such layered silicates, such as those having the general formula NaMSi x ⁇ 2 ⁇ + 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 can be used herein.
- Various other layered silicates from Hoechst include NaSKS-5, NaSKS-7 and NaSKS-11, as the alpha, beta and gamma forms.
- delta-Na2SiO5 (NaSKS-6 form) is most preferred for use herein.
- Other silicates may also be useful such as for example magnesium silicate, which can serve as a crispening agent in granular formulations, as a stabilizing agent for oxygen bleaches, and as a component of suds control systems.
- carbonate builders are the alkaline earth and alkali metal carbonates as disclosed in German Patent Application No. 2,321,001 published on November 15, 1973.
- Aluminosilicate builders are useful in the present invention. Aluminosilicate builders are of great importance in most currently marketed heavy duty granular detergent compositions, and can also be a significant builder ingredient in liquid detergent formulations. Aluminosilicate builders include those having the empirical formula:
- M zJn [(Ai ⁇ 2 S ⁇ 0 2 )y) xH 2 O
- z and y are integers usually of at least 6, the molar ratio of z to y is in the range from 1.0 to 0, and x is an integer from 0 to about 264
- M is a Group IA or IIA element, e.g., Na, K, Mg, Ca with valence n.
- Useful aluminosilicate ion exchange materials are commercially available.
- aluminosilicates can be crystalline or amorphous in structure and can be naturally-occurring aluminosilicates or synthetically derived.
- a method for producing aluminosilicate ion exchange materials is disclosed in U.S. Patent 3,985,669, Krummel, et al, issued October 12, 1976.
- Preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X.
- the crystalline aluminosilicate ion exchange material has the formula:
- Organic detergent builders suitable for the purposes of the present invention include, but are not restricted to, a wide variety of polycarboxylate compounds. As used herein, "polycarboxylate” refers to compounds having a plurality of carboxylate groups, preferably at least 3 carboxylates.
- Polycarboxylate builder can generally be added to the composition in acid form- but can also be added in the form of a neutralized salt.
- alkali metals such as sodium, potassium, and lithium, or alkanolammonium salts are preferred.
- polycarboxylate builders include a variety of categories of useful materials.
- One important category of polycarboxylate builders encompasses the ether polycarboxylates, including oxydisuccinate, as disclosed in Berg, U.S. Patent 3,128,287, issued April 7, 1964, and Lamberti et al, U.S. Patent 3,635,830, issued January 18, 1972. See also "TMS/TDS" builders of U.S. Patent 4,663,071, issued to Bush et al, on May 5, 1987.
- Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U.S. Patents 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903.
- ether hydroxypolycarboxylates copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1, 3, 5-trihydroxy benzene-2, 4, 6-trisulphonic acid, and carboxymethyloxysuccinic acid
- various alkali metal, ammonium and substituted ammonium salts of polyacetic acids such , as ethylenediamine tetraacetic acid and nitrilotriacetic acid
- polycarboxylates such as mellitic acid, succinic acid, oxydisuccinic acid, polymaleic acid, benzene 1,3,5- tricarboxylic acid, carboxymethyloxysuccinic acid, and soluble salts thereof.
- Citrate builders e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty liquid detergent formulations due to their availability from renewable resources and their biodegradability. Citrates can also be used in granular compositions, especially in combination with zeolite and/or layered silicate builders. Oxydisuccinates are also especially useful in such compositions and combinations.
- succinic acid builders include the C5-C20 a * an ⁇ alkenyl succinic acids and salts thereof.
- a particularly preferred compound of this type is dodecenylsuccinic acid.
- succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2-pentadecenylsuccinate, and the like. Laurylsuccinates are the preferred builders of this group, and are described in European Patent Application 86200690.5/0,200,263, published November 5, 1986. Other suitable polycarboxylates are disclosed in U.S. Patent 4,144,226,
- Fatty acids e.g., Ci2-C ⁇ g monocarboxylic acids such as oleic acid and/or its salts
- Ci2-C ⁇ g monocarboxylic acids such as oleic acid and/or its salts
- Such use of fatty acids will generally result in a diminution of sudsing, which should be taken into account by the formulator.
- the various alkali metal phosphates such as the well-known sodium tripolyphosphates, sodium pyrophosphate and sodium orthophosphate can be used.
- Phosphonate builders such as ethane- l-hydroxy-l,l-diphosphonate and other known phosphonates (see, for example, U.S. Patents 3,159,581; 3,213,030; 3,422,021; 3,400,148 and 3,422,137) can also be used.
- Enzymes - Enzymes can be included in the formulations herein for a wide variety of fabric laundering purposes, including removal of protein-based, carbohydrate-based, or triglyceride-based stains, for example, and for the prevention of refugee dye transfer, and for fabric restoration.
- the enzymes to be incorporated include proteases, amylases, lipases, cellulases, and peroxidases, as well as mixtures thereof.
- Other types of enzymes may also be included. They may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. However, their choice is governed by several factors such as pH- activity and/or stability optima, thermostability, stability versus active detergents, builders and so on. In this respect bacterial or fungal enzymes are preferred, such as bacterial amylases and proteases, and fungal cellulases.
- Enzymes are normally incorporated at levels sufficient to provide up to about 5 mg by weight, more typically about 0.001 g to about 3 mg, of active enzyme per gram of the composition. Stated otherwise, the compositions herein will typically comprise from about 0.001% to about 5%, preferably 0.01%-2% by weight of a commercial enzyme preparation. Protease enzymes are usually present in such commercial preparations at levels sufficient to provide from 0.005 to 0.1 Anson units (AU) of activity per gram of composition. Suitable examples of proteases are the subtilisins which are obtained from particular strains of B. subtilis and B. licheniforms.
- protease is obtained from a strain of Bacillus, having maximum activity throughout the pH range of 8-12, developed and sold by Novo Industries A/S under the registered trade name ESPERASE. The preparation of this enzyme and analogous enzymes is described in British Patent Specification No. 1,243,784 of Novo.
- Proteolytic enzymes suitable for removing protein-based stains include those sold under the tradenames ALCALASE and SAVINASE by Novo Industries A S (Denmark) and MAXATASE by International Bio- Synthetics, Inc.

- suitable cellulases are also disclosed in GB-A-2.075.028; GB-A-2.095.275 and DE-OS- 2.247.832. CAREZYME (Novo) is especially useful.
- Suitable lipase enzymes for detergent usage include those produced by microorganisms of the Pseudomonas group, such as Pseudomonas stutzeri ATCC 19.154, as disclosed in British Patent 1,372,034. See also lipases in Japanese Patent Application 53,20487, laid open to public inspection on February 24, 1978. This lipase is available from Amano Pharmaceutical Co. Ltd., Nagoya, Japan, under the trade name Lipase P "Amano,” hereinafter referred to as "Amano-P.” Other commercial lipases include Amano-CES, lipases ex Chromobacter viscosum, e.g. Chromobacter viscosum var.
- lipolyticum NRRLB 3673 commercially available from Toyo Jozo Co., Tagata, Japan; and further Chromobacter viscosum lipases from U.S. Biochemical Corp., U.S.A. and Disoynth Co., The Netherlands, and lipases ex Pseudomonas gladioli.
- the LIPOLASE enzyme derived from Humicola lanuginosa and commercially available from Novo is a preferred lipase for use herein.
- Peroxidase enzymes are used in combination with oxygen sources, e.g., percarbonate, perborate, persulfate, hydrogen peroxide, etc. 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, published October 19, 1989, by O. Kirk, assigned to Novo Industries A/S. It may be desired to use, in combination with these peroxidases, materials viewed as being peroxidase accelerators such as phenolsulfonate and/or phenothiazine.
- Enzyme Stabilizers - Enzymes for use in detergents can be stabilized by various techniques. Enzyme stabilization techniques are disclosed and exemplified in U.S. Patent 3,600,319, issued August 17, 1971 to Gedge, et al, and European Patent Application Publication No. 0 199 405, Application No. 86200586.5, published October 29, 1986, Venegas. Enzyme stabilization systems are also described, for example, in U.S. Patent 3,519,570.
- the enzymes employed herein can be stabilized by the presence of water-soluble sources of calcium and/or magnesium ions in the finished compositions which provide such ions to the enzymes. (Calcium ions are generally somewhat more effective than magnesium ions and are preferred herein if only one type of cation is being used.)
- Additional stability can be provided by the presence of various other art- disclosed stabilizers, especially borate species: see Severson, U.S. 4,537,706.
- Typical detergents, especially liquids will comprise from about 1 to about 30, preferably from about 2 to about 20, more preferably from about 5 to about 15, and most preferably from about 8 to about 12, millimoles of calcium ion per liter of finished composition. This can vary somewhat, depending on the amount of enzyme present and its response to the calcium or magnesium ions.
- the level of calcium or magnesium ions should be selected so that there is always some minimum level available for the enzyme, after allowing for complexation 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 malate, calcium maleate, calcium hydroxide, calcium formate, and calcium acetate, and the corresponding magnesium salts.
- a small amount of calcium ion generally from about 0.05 to about 0.4 millimoles per liter, is often also present in the composition due to calcium in the enzyme slurry and formula water.
- the formulation may include a sufficient quantity of a water-soluble calcium ion source to provide such amounts in the laundry liquor. In the alternative, natural water hardness may suffice.
- compositions herein will typically comprise from about 0.05% to about 2% by weight of a water-soluble source of calcium or magnesium ions, or both.
- the amount can vary, of course, with the amount and type of enzyme employed in the composition.
- the compositions herein may also optionally, but preferably, contain various additional stabilizers, especially borate-type stabilizers.
- such stabilizers will be used at levels in the compositions from about 0.25% to about 10%, preferably from about 0.5% to about 5%, more preferably from about 0.75% to about 4%, 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 (e.g., sodium ortho-, meta- and pyroborate, and sodium pentaborate) are suitable.

- the combination of such selected polymeric materials (e.g., PVNO and/or PVPVI) with such selected optical brighteners (e.g., Tinopal UNPA-GX, Tinopal 5BM-GX, Tinopal-PLC, and/or Tinopal AMS-GX) provides significantly better dye transfer inhibition in aqueous wash solutions than does either of these two detergent composition components when used alone. Without being bound by theory, it is believed that such brighteners work this way because they have high affinity for fabrics in the wash solution and therefore deposit relatively quick on these fabrics.
- the extent to which brighteners deposit on fabrics in the wash solution can be defined by a parameter called the "exhaustion coefficient".
- the exhaustion coefficient is in general as the ratio of a) the brightener material deposited on fabric to b) the initial brightener concentration in the wash liquor. Brighteners with relatively high exhaustion coefficients are the most suitable for inhibiting dye transfer in the context of the present invention.
- Brightener Any optical brighteners or other brightening or whitening agents known in the art can be incorporated at levels typically from about 0.05% to about 1.2%, by weight, into the detergent compositions herein.
- Commercial optical brighteners which may be useful in the present invention can be classified into subgroups, which include, but are not necessarily limited to, derivatives of stilbene, pyrazoline, coumarin, carboxylic acid, methinecyanines, dibenzothiphene-5,5-dioxide, azoles, 5- and 6-membered-ring heterocycles, and other miscellaneous agents. Examples of such brighteners are disclosed in "The Production and Application of Fluorescent Brightening Agents", M. Zahradnik, Published by John Wiley & Sons, New York (1982).
- optical brighteners which are useful in the present compositions are those identified in U.S. Patent 4,790,856, issued to Wixon on December 13, 1988. These brighteners include the PHORWHITE series of brighteners from Verona.
