The present invention relates to a composition comprising water, at least one surfactant, at least one ester of levulinic acid with a fatty alcohol and a water-soluble salt. Furthermore the present invention relates to the use of at least one ester of levulinic acid with a fatty alcohol for increasing the viscosity of a composition comprising water and at least one surfactant.

Cosmetic composition comprising ester of levulinic acid with a fatty alcohol

The invention relates to mixtures of alkyl sulfosuccinate monoesters of general formulas (I) and/or (II), in which R represents a linear or branched, saturated or unsaturated alkyl group having 6 to 22 C atoms, and X and Y independently represent a hydrogen atom or a cation that can form a water-soluble salt and is selected from among the group composed of alkali metal, alkaline earth metal, ammonia, and organic ammonia. The invention is characterized in that the mixture contains 30 to 70 percent by weight of C16 alkyl sulfosuccinate monoester and 30 to 70 percent by weight of C18 alkyl sulfosuccinate monoester, the percentages by weight being in relation to the total amount of alkyl sulfosuccinate monoesters of formulas (I) and (II). The invention also relates to the use of said mixtures in cosmetic and/or pharmaceutical preparations. 

Alkyl sulfosuccinate mixtures, and use thereof

A process for reducing the amount of halocarbons in a mixture containing water and at least one of an alkyl or alkenyl glycoside carboxylic acid. The amount of halocarbon is reduced by heating the mixture at a temperature of 50&#xb0; C. to 120&#xb0; C. at a pH of from 10-14. The amount of organomonochloro compounds can be reduced to a range of 5 ppm or less and the amount of organodichloro compounds can be reduced to a range of 30 ppm.

Method for producing alkyl oligoglucoside and alkenyl oligoglucoside carboxylic acid salts with reduced organochloride compounds

An aqueous surfactant mixture comprised of an alkyl and/or alkenyl oligoglycoside ether carboxylic acid is made by a process comprising reacting in an aqueous solution an alkyl and/or alkenyl oligoglycoside and an &#x3c9;-halocarboxylic acid or a salt or ester thereof in the presence of alkali.

Method for the production of surface active agent mixtures

Processes for preparing alkoxylated nonionic surfactants are disclosed, wherein a compound having at least one active hydrogen atom, a carboxylic acid ester or mixtures thereof are reacted with an alkylene oxide in the presence of a hydrotalcite catalyst to form a reaction product mixture; and the reaction product mixture is combined with an acid in at least an equimolar amount based on the amount of the catalyst present.
