PREPARATIONS IN EMULSION OF THE WATER TYPE IN OIL (W / O) WITH HIGH CONTENT IN WATER, PROVIDED IN ADDITION TO ONE OR MISCELLANEOUS ALKYLMETICONE COPOLIOLS AND / OR ALKYL DIMETICONE COPOLIOLS AS WELL AS CATIONIC POLYMERS.

摘要

The invention relates to water-in-oil (W / O) emulsions, for use in pharmaceutical and cosmetic compositions comprising cationic polymers and alkyl-methicone copolymers and / or alkyl dimethicone copolymers, as surfactants. The water-in-oil emulsion comprises water and lipid components, cationic polymers and alkylmethicone copolymer and / or alkyl dimethicone copolymers as a surfactant. W / O emulsions comprise: (a) a water content and optionally water soluble substances of at least 80% by weight; (b) a content of lipids, emulsifiers and lipophilic components of at least 20% by weight; (c) alkyl methicone copolymer and / or alkyl dimethicone copolymer as a surfactant; (d) one or more lipid components that form the oil phase of the emulsion; (e) at least one cationic polymer. The weight ratio of (b) :( c) is 0.1 to 0.25.
