摘要:
Stable, topically applicable cosmetic/dermatological compositions, notably W/O emulsions, well suited for the UV-photoprotection of the skin, lips and/or the hair, and/or for the makeup of the skin and/or the lips, contain a thus effective amount of at least one mineral oxide having a hydrophobic coating thereon, e.g., coated particulates of an oxide of titanium and/or zinc, and, as a stabilizing agent therefor, a thus effective amount of at least one oxyalkylenated polydimethylsiloxane bearing at least one glycoside residue substituent, formulated into a physiologically acceptable medium therefor.
摘要:
A pressurized device comprising an “ultrafine” foaming oil-in-water emulsion wherein the particle size of the oil particles constituting the oil phase ranges from 50 to 1000 nm, the ultrafine emulsion being preferably obtained according to the so-called “phase inversion” technique. These ultrafine oil-in-water emulsions can be employed in particular for cleansing and care of the skin and they are rich in oils, fluid, pressurizable, foaming and translucent.
