Abstract:
The present invention relates to the formation of surface treated zinc oxide and titania particles, and in particular zinc oxide and titania nanoparticles, with a siloxane star-graft copolymer coating, comprising a looped and/or linear polymeric structure on a star-graft copolymer coating, on a particle surface to control the interfacial surface interactions between the particle and the oil phase of the cosmetic skin formulation.
Abstract:
The invention relates to pharmaceutical and cosmetic agents that comprise alcohol alkoxylate components that are derived from branched C 10 alcohols, to surfactant mixtures derived from said alcohol alkoxylates and to the use of said alcohol alkoxylates as solubilizers.
Abstract:
The invention relates to a method for the production of powdered preparations containing 2,4,6-trianilino-p-(carbo-2'-ethylhexyl-1'-oxi)-1,3,5-triazine of formula I and diethylamino-hydroxybenzoyl-hexyl-benzoate of formula II by a) jointly dispersing compounds I and II in an aqueous molecularly disperse or colloidally disperse solution of a protective colloid, and b) converting the obtained dispersion into a dry powder by eliminating the water and additionally used solvents, if applicable, and drying. The inventive method is characterized in that modified starch is used as a protective colloid in step a).
Abstract:
The invention relates to surface-modified nanoparticulate metal oxides, methods for production and use thereof as UV filter in cosmetic preparations.
Abstract:
The invention relates to a method for producing an aqueous amorphous titanium dioxide dispersion having an average particle size ranging from 10 to 500 nm. The inventive method is characterized in that at least one titanium tetraalcoholate of general formula Ti(OR) 4 , wherein R = C 1 to C 6 alkyl, is hydrolyzed in the aqueous dispersion.
