The invention relates to polysiloxane block copolymers of the formula A[LB(S)Q], where A is a polysiloxane block, L is a divalent organic linker, B is a polymer block composed of radically polymerizable monomers, S is a sulfur atom and Q is a monovalent organic radical and m is an integer from 1 to 50, to a method for their production, and to their use in cosmetics or personal care.

Polysiloxane block copolymers

The present invention relates to polyglycerol partial esters of polyhydroxystearic acid and polyfunctional carboxylic acids which are obtainable by esterification of a polyglycerol mixture with polyhydroxystearic acid where N=1 to 10, preferably 2 to 8, in particular 3 to 5 units and dimer fatty acids which have been obtained by catalytic dimerization of unsaturated fatty acids having 12 to 22 C atoms and have an average functionality of 2 to 3, and/or with aliphatic, linear or branched dicarboxylic acids having a chain length of 2 to 16 C atoms and additionally saturated or unsaturated, linear or branched fatty acids having 6 to 22 C atoms, preferably 12 to 18 C atoms, the degree of esterification of the polyglycerol mixture being between 20 and 75%, preferably 40 to 70%.

Emulsifier for highly liquid W/O emulsion based on partly crosslinked polyglycerol esters of polyhydroxystearic acid

Compounds of the general formula and to the use thereof for controlling microorganisms are provided.

Antimicrobial compositions

The use of ester quats in compositions, the ester quats producing a sand-repellent action for the compositions, comprising cosmetic compositions, and the use of these cosmetic compositions having a sand-repellent action for topical application, for example for protection of the skin against ultraviolet radiation are provided. The present application in particular relates to the use of at least one ester quat based on alkanolamines in compositions, the ester quats producing a sand-repellent action for the compositions, and the acyl component of the ester quats being derived from

Use of ester quats in compositions as sand-repellent substances

The present invention relates to a newly identified hydrolase from thermophilic microorganisms having thermostable properties, and more specifically, to a novel thermostable hydrolase showing high activity at high temperatures.

Thermostable esterases from thermophilic bacteria

The invention provides a process for preparing amino acid esters and/or their acid addition salts from monomeric or polymeric amino acids, peptides, proteins and alcohols, which comprises carrying out the reaction in supercritical alcohols, preferably at pressures and temperatures which are at least 5% above the critical parameters, the alcohols serving both as the solvent and as reactants.

Process for preparing amino acid esters and their acid addition salts

The invention relates to a process for preparing highly concentrated flowable and pumpable aqueous solutions of betaines by quaternization of compounds containing tertiary amine nitrogen with &#x3c9;-halocarboxylic acids by known processes, wherein 0.1 to less than 3% by weight, preferably 0.1 to 1% by weight, based on the end product, of one or more micellar thickeners are added to the reaction mixture before or during the quaternization reaction.
