Abstract: An aqueous polymer dispersion with an average particle size of less than 1000 nm comprising a) a polymer carrier prepared by heterophase radical polymerization of at least one ethylenically unsaturated monomer in the presence of b) an oil-soluble organic UV absorber selected from the class of p-aminobenzoic acid derivatives; salicylic acid derivatives; benzophenone derivatives; diphenyl acrylate derivatives; benzofuran derivatives; polymeric UV absorbers, comprising one or more organosilicon radicals; cinnamic acid derivatives; camphor derivatives; s-triazine derivatives; trianilino-striazine derivatives; menthyl anthranilates; and benzotriazole derivatives; wherein the weight ratio of the oil-soluble organic UV absorber (b) to polymer carrier (a) is greater than 50 parts UV absorber per 100 parts of carrier; and c) a surfactant selected from c1) a nonionic surfactant selected from c11) the condensation product of a C6 to C18 fatty alcohol or C6 to C18 fatty acid and a mono- or disaccharide; and c2) an anionic surfactant selected from c21) sulfosuccinates and sulfosuccinamates; c22) fatty alcoholates; and c23) mixtures of phosphoric acid esters and fatty alcohols having from 6 to 18, preferably from 8 to 10, carbon atoms. The aqueous polymer dispersions show unexpectedly high sunscreen effects and a positive skin feeling. They have excellent anti-pollen, anti-dust and anti-oxidant performances in sun screen compositions.

Abstract: The present invention relates to novel mono- and diesters of 2,5-di(hydroxymethyl)tetrahydrofuran, processes for their preparation by esterification in the presence of tertiary amines or in the presence of enzymatic esterification catalysts and the use of these mono- and diesters as interface-active compounds, rheology modifiers and emollients. The invention further relates to cosmetic and pharmaceutical compositions, and to detergents, cleaners and dishwashing compositions which comprise these mono- and diesters of 2,5-di(hydroxymethyl)-tetrahydrofuran.

Abstract: A polyolester mixture as substitute for vaseline obtainable by esterification reaction of a) 0.8 to 1.2 mol glycerin b) 0.5 to 0.7 mol sebacic acid c) 1.0 to 1.4 mol of a monocarboxylic fatty acid mixture with a chain length of 8 to 24 carbon atoms characterized in that the fatty acid mixture c) comprises at maximum 30 wt % of a linear C18 fatty acid, at maximum 3 wt % of fatty acids lower than C12 and at maximum 3 wt % of fatty acids higher than C18 based on the weight of the sum of monocarboxylic fatty acids.
