Aqueous surfactant compositions

The present invention relates to an alkyl glycoside sulfomethylsuccinate having the formula R-O-S-Rwherein Ris an alkyl radical having 6 to 30 carbon atoms, S is a monosaccharide moiety, and Ris a sulfomethylsuccinate moiety. Furthermore the present invention relates to a process for making this alkyl glycoside sulfomethylsuccinate and to an alkyl glycoside itaconate which is a useful intermediate for use in this process. Furthermore the present invention relates to a cosmetic composition comprising the alkyl glycoside sulfomethylsuccinate and to the use of the alkyl glycoside sulfomethylsuccinate for improving the foam stability of a cosmetic composition.

Alkylglycoside sulfomethylsuccinate surfactants

Solubilizing agents for UV filters in cosmetic formulations

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 patent application relates to a process for preparing polyoxymethylene by polymerization of a reaction mixture (R) which comprises at least one formaldehyde source and at least one initiator mixture (I), wherein the initiator mixture (I) comprises at least one polymerization initiator and at least one solvent of the general formula (I)R&#x2014;O&#x2014;[&#x2014;R&#x2014;O&#x2014;]&#x2014;R&#x2003;&#x2003;(I),

Process for preparing polyoxymethylene

This invention relates to a process for stabilizing polymers with oligomeric carbodiimides containing at least one heterocyclic end group and stabilizers. The oligomeric carbodiimides may be compounds of the general formula (I): where A, Aare each independently, identically or differently, hydrocarbon groups having 2 to 20 carbon atoms, B, Bare each independently, identically or differently, heterocycles, C-C-alcohols, polyetherols, polyesterols, amines, polyether amines, polyester amines, thioalcohols, polyether thiols, polyester thiols; R, Rare each independently, identically or differently: n is an integer from 2 to 100, and A, A, Band Bmay each be substituted at any desired position by C-C-alkyl, C-C-alkenyl, C-C-alkynyl, C-C-alkoxy, carbonyl oxygen (&#x2550;O) or halogen, with the proviso that at least one Bor Bsubstituent is a heterocyclic end group. The invention also relates to compositions of the oligomeric carbodiimides and mixtures.
