Crosslinked oil-in-water emulsions or gel creams with stable droplet size, especially for cosmetic or dermatological use, obtained e.g. by adding crosslinker to low viscosity oil-in-water emulsion

摘要

Production of crosslinked oil-in-water (O/W) type emulsions or gel creams (A), having a non-volatile oil phase and containing O/W emulsifier(s) (I), crosslinker(s) (II) and optionally water-in-oil (W/O) emulsifier(s) (III), auxiliaries, additives and/or active agents. Production of crosslinked oil-in-water (O/W) type emulsions or gel creams (A), having a non-volatile oil phase and containing O/W emulsifier(s) (I), crosslinker(s) (II) and optionally water-in-oil (W/O) emulsifier(s) (III), auxiliaries, additives and/or active agents, involves: (a) adding the aqueous phase to the oil phase (at least one of which contains (II)) and adding (I) and optionally (III), causing a viscosity increase; (b) bringing the mixture to a temperature inside or outside the phase inversion region then cooling, causing a viscosity increase; or (c) adding (II) to a low viscosity O/W emulsion.
