Description

Technical Field

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

[0002] Surfactant combinations are known to provide better cleaning in laundry, as different types of surfactants have advantages in different cleaning areas. Laundry formulations containing a lauryl (C12) ether sulfate surfactant in combination with a C12-15 alcohol ethoxylate surfactant are widely used, especially detergents composed of green surfactants. Green surfactants are surfactants synthesized from plant materials rather than petrochemicals.

[0003] In a surfactant combination, it is desirable to keep the critical micelle concentration (cmc) as low as possible, since for many stains effective cleaning only occurs above the cmc. The problem with the combination of lauryl ether sulfate surfactants with C12-15 alcohol ethoxylates is that their cmc is high. This is particularly pronounced when the surfactant mixture contains a high ratio of lauryl ether sulfate, since the cmc increases rapidly as the alcohol ethoxylate content decreases.

[0004] The question is how to lower the critical micelle concentration in a surfactant mixture using a mixture of nonionic and anionic surfactants.

[0005] Surprisingly, this problem can be solved by the combination of C16 / C18 ether sulfate and C16 / C18 alcohol ethoxylate. The resulting surfactant mixture has a much lower cmc at a 1:1 molar ratio, and the cmc does not increase when the surfactant mixture contains a high ratio of C16 / C18 ether sulfate.

[0114] 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.

[0115] 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. Phospholipases are enzymes involved in the hydrolysis of phospholipids. 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.

[0116] 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. The term "subtilase" refers to a subgroup of serine proteases according to Siezen et al., Protein Engng. 4 (1991) 719-737 and Siezen et al., Protein Science 6 (1997) 501-523. 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.

[0117] Examples of subtilases are those derived from Bacillus, such as Bacillus lentus, Bacillus alkalophilus, Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus pumilus and Bacillus gibsonii described in US 7262042 and WO 09 / 021867, and subtilisin lentus, subtilisin Novo, subtilisin Carlsberg, Bacillus licheniformis, subtilisin BPN', subtilisin 309, subtilisin 147 and subtilisin 168 described in WO 89 / 06279, and protease PD138 described in WO 93 / 18140.

[0183] The present invention will be further described by the following non-limiting examples.

[0184] Example

[0185] The critical micelle concentration (cmc) is measured by using a Kibron multichannel tensiometer that measures the air-water surface tension. The method involves a series of dilutions of the aqueous sample in question, ranging from 2500ppm to 1ppm. The surface tension of these samples is measured, and the cmc is determined as the inflection point in a graph of surface tension versus Log (concentration in ppm) where the surface tension does not continue to decrease with increasing concentration.

[0186] The surfactants used were:

[0187] LES - Lauryl ether sulfate 3 mole ethoxylated on average.

[0188] C12(EO7) - C12-15 alcohol ethoxylate with an average of 7 moles of ethoxylation (alkyl chains are mainly C12)

[0189] CES-10 mole average ethoxylated cetearyl ether sulfate (CES) (alkyl chains are a mixture of C16 and C18)

[0190] C18:1(Δ9)-oleyl / elai alcohol ethoxylate with an average of 10 moles of ethoxylation.

[0191] The results are given in the table below. Formulations AC are control references and formulation 1 is according to the invention.

[0192]

[0193] For a mixture of LES and Cl2(EO7), which reflects many commercial surfactant systems, the cmc is very high. When the amount of nonionic surfactant in the mixture is reduced, the cmc even increases (up to 52%, reaching 1444 at 100% LES).

[0194] However, for the combination of cetearyl (C16-C18) ether sulfate and oleyl alcohol ethoxylate, the resulting surfactant mixture has a much lower cmc at a 1:1 molar ratio, and the cmc does not rise when the surfactant mixture contains high fractions of C16 / C18 ether sulfate (up to 3%, reaching 173 when CES is 100%).
