摘要:
An aqueous dispersion containing pyrogenically prepared oxide particles of titanium, zinc, iron or cerium with an average particle size, expressed as the median, in the dispersion of less than 250 nm, that the particle sizes of the oxide particles in the dispersion are not distributed symmetrically and the dispersion contains, as a dispersant, at least one compound of the formula (I) and/or a maleic anhydride/acrylate copolymer of the general formula (IIa) and/or a maleate/acrylate copolymer of the general formula (IIb). It is prepared by dispersing a predispersion stream by means of a high energy mill. It can be used in sunscreen formulations.

摘要:
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 (a) monocarboxylic acids, (b) dicarboxylic acids, (c) tricarboxylic acids, or their mixtures.
