Description

Technical Field

[0001] The present invention relates to detergent compositions, and more particularly to detergent compositions comprising C16 and / or C18 ether sulfate surfactants. Background Art

[0002] Alcohol ether sulfates are widely used in cleaning applications such as laundry to solubilize fat. Alcohol ether sulfate surfactants (eg sodium lauryl ether sulfate) are synthesized using alcohols with C10-C14, especially C12 (lauryl) alkyl chains as starting materials for use in laundry detergents.

[0003] The key issue with this type of alcohol ether sulfate is foam control. For lauryl (C12) and myristyl (C14) ether sulfates, foam levels can be extremely high and lead to excessive foaming in the washing machine and the use of too much water in the rinse water to remove the foam.

[0004] The problem is how to reduce the foam level of compositions containing these useful materials.

[0005] Surprisingly, this problem can be solved by including C16 and / or C18 ether sulfates. Summary of the invention

[0027] The saturated materials may also be described as lauryl (C12) and / or myristyl (C14) ether sulfates having a molar average of 1 to 4, preferably 1.5 to 3.5, ethoxylated groups.

[0028] C16 and / or C18 ether sulfates

[0029] Alcohol ether sulfates are discussed in Anionic Surfactants: Organic Chemistry, edited by HW Stache (Marcel Dekker, New York 1996).

[0030] The composition comprises 2-25 wt%, preferably 3-20 wt%, most preferably 4-15 wt% of C16 and / or C18 ether sulfate.

[0031] C16 and / or C18 ether sulfate is R2-(OCH2CH2) n Ether sulfates of the form OSO3H, wherein R2 is a saturated or monounsaturated straight chain C16 and C18 alkyl group, and wherein n is 5-20, preferably 6-14, more preferably 7-13, most preferably 7-12. The monounsaturation is preferably at position 9 of the chain, and the double bond may be in cis or trans configuration (oleyl or anti-oleyl). The cis or trans ether sulfates CH3(CH2)7-CH=CH-(CH2)8O-(OCH2CH2) n OSO3H is described as C18:1 (Δ9) ether sulfate. 18 is the number of carbon atoms in the chain, 1 is the number of double bonds, and Δ9 is the position of the double bond on the chain. Most preferably, R2 is selected from linear C16 alkyl, linear C18 alkyl, linear C18:1 (Δ9) alkyl, and mixtures thereof.

[0032] Preferred examples are C16 and / or C18 ether sulfates having an alkyl chain selected from a mixture of cetyl (linear C16) and stearyl (linear C18); oleyl ether sulfate and elaiyl ether sulfate; and mixtures thereof.

[0033] Oleyl ether sulfate has a monounsaturated C18 chain with a cis double bond at position 9 of the chain. Elaidyl ether sulfate has a monounsaturated C18 chain with a trans double bond at position 9 of the chain.

[0034] The alcohol ether sulfates can be synthesized by ethoxylating an alkyl alcohol to form an alcohol ethoxylate, followed by sulfonation and neutralization with a suitable base.

[0035] The production of alcohol ethoxylates involves the ethoxylation reaction:

[0036] R-OH+q ethylene oxide→RO-(CH2CH2O)qH

[0037] Such ethoxylation reactions are described in Non-Ionic Surfactant Organic Chemistry (NM van Osed), Surfactant Science Series Volume 72, CRC Press.

[0038] Preferably, the reaction is base catalyzed using NaOH, KOH or NaOCH3. Even more preferred are catalysts that provide a narrower ethoxyl distribution than NaOH, KOH or NaOCH3. Preferably, these narrower distribution catalysts involve Group II bases such as barium dodecanoate described in WO 2007 / 147866; Group II metal alkoxides; Group II hyrodrotalcites.

[0040] For example, when q=10, then more than 70% by weight of the alcohol ethoxylates should consist of ethoxylates having 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15 ethoxylate groups.

[0099] The present invention may be performed in the presence of a phospholipase classified as EC 3.1.1.4 and / or EC 3.1.1.32. As used herein, the term phospholipase is an enzyme active towards phospholipids.

[0100] Phospholipids, such as lecithin or phosphatidylcholine, consist of glycerol esterified with two fatty acids in the outer (sn-1) and middle (sn-2) positions and esterified with phosphate in the third position; the phosphate can in turn be esterified to an amino alcohol.

Several types of phospholipase activity can be distinguished, including phospholipases A1 and A2, which hydrolyze one acyl group (at the sn-1 and sn-2 positions, respectively) to form lysophospholipids; and lysophospholipases (or phospholipases B), which can hydrolyze the remaining acyl groups in lysophospholipids. Phospholipase C and phospholipase D (phosphodiesterase) release diacylglycerol or phosphatidic acid, respectively.

[0101] Proteases hydrolyze bonds within peptides and proteins, which in the laundry context results in enhanced removal of protein or peptide containing stains. Examples of suitable protease families include aspartic proteases; cysteine ​​proteases; glutamic proteases; asparagine (aspargine) peptide cleaving enzymes; serine proteases and threonine proteases. Such protease families are listed in the MEROPS Peptidase Database ( http: / / merops.sanger.ac.uk / ). Serine proteases are preferred. Subtilase-type serine proteases are more preferred.

Serine proteases are a subgroup of proteases characterized by having a serine in the active site, which forms a covalent adduct with the substrate. Subtilases can be divided into 6 subclassifications, namely the subtilisin family, the thermophilic protease (Thermitase) family, the proteinase K family, the lantibiotic (Lantibiotic) peptidase family, the Kexin family and the Pyrolysin family.

[0168] Example

[0169] A laundry detergent containing 10 wt% surfactant (the remainder being water) was added to 6° fH (French hardness) water at 293 K to give a 0.2 g / L surfactant aqueous solution.

[0170] 10 ml of the solution was placed in a 2.2 cm diameter tube and plugged. The tube was inverted 40 times to generate foam and a photo of the tube was taken. Soil was then added in 1 mg portions and the inversion process and photo cycle were repeated until 4 mg of total soil was added. The soil was an emulsion of olive oil: water: kaolin + 0.13 wt% flour in a weight ratio of 5:5:1. Kaolin was purchased from Sigma-Aldrich.

[0171] The height of the foam was measured as the difference between the meniscus and the top of the foam. The experimental values ​​are the average of 2 replicate tubes.

[0172] Soil level versus foam height was plotted for 1-4 mg soil and a straight line was fit to the points using regression analysis (LINEST function of Microsoft Excel).

[0173] The gradient is the change in foam level per unit of stain (Δ foam ), and the intercept is the maximum foam ( foam Max). The values ​​are given in the table below along with the standard error (± value). The expected value is calculated based on the inclusion level in a linear relationship from the 100% value.

[0174]

[0175] Cetearyl is a mixture of C16 and C18 straight saturated chains.

[0176] Lauryl is a C12 straight saturated chain.

[0177] The values ​​marked with * are according to the invention, the other values ​​are comparative.

[0178] Foam from 100% surfactants Max Experimental error calculation bubble Max Expected error limits.

[0179] The observed difference between the experiment and the expectation is larger than the error.

[0180] Surprisingly, the mixture of lauryl and C16 and / or C18 ether sulfates in the desired weight ratios produced foam (foam Max Experiment) lower than expected (bubble Max expected), and the reduction in stains (Δfoam) was higher than expected (experimental value was less than the calculated expected value).

[0181] Example 2

[0182] A laundry detergent containing 10 wt% surfactant (the remainder being water) was added to 6° fH (French hardness) water at 293 K to give a 0.15 g / L surfactant aqueous solution.

[0183] 10 ml of the solution was placed in a 2.2 cm diameter tube and plugged. The tube was inverted 40 times to generate foam and a photo of the tube was taken. The soil was then added in 1 mg aliquots and the inversion process and photo cycle were repeated until 4 mg of total soil was added. The soil was an emulsion of olive oil: water: kaolin + 0.13 wt% flour in a weight ratio of 5:5:1. Kaolin was purchased from Sigma-Aldrich. Different batches of soil ingredients were used in Example 1.

[0184] The height of the foam was measured as the difference between the meniscus and the top of the foam. The experimental values ​​are the average of 3 replicate tubes.

[0185] Soil level versus foam height was plotted for 1-4 mg stains and a straight line was fit to the points using regression analysis (LINEST function of Microsoft excel).

[0186] The gradient is the change in foam level per unit of stain (Δ foam ), and the intercept is the maximum foam ( foam Max ). The values ​​are given in the table below along with the standard error (± value). The expected value is calculated based on the inclusion level in a linear relationship from the 100% value.

[0187]

[0188] The oil base is a monounsaturated C18 chain with an average of 6 moles of ethoxylation.

[0189] Lauryl is a C12 straight saturated chain having an average of 3 moles of ethoxylation.

[0190] The values ​​marked with * are according to the invention, the other values ​​are comparative.

[0191] Foam made from 100% surfactants Max Experimental error calculation bubble Max Expected error limits.

[0192] The comparative example of 88:12 lauryl:oleyl (7.3:1 ratio) reflects the teaching of the prior art (which is 8.5 wt. % lauryl to 0.7 wt. % oleyl (which gives a ratio of about 12:1)) fairly well because it is closer to the end point of the 5:1 to 1:8 range of the present invention.

[0193] Foam from surfactant mixtures Max The experimental values ​​are significantly lower than the expected values, except for 88:12 lauryl:oil, where this value is within error. The percentage improvement in the improved foam technical effect is better for the mixtures of the claimed materials compared to the prior art mixtures.

[0194] Surprisingly, the mixture of lauryl and C16 and / or C18 ether sulfates in the desired weight ratios produced foam (foam Max Experiment) significantly lower than expected (bubble Max expected), and the reduction in stains (Δfoam) was higher than expected (experimental value was less than the calculated expected value).
