COSMETIC OR DERMOTALOG COMPOSITIONS FOR TOPICAL APPLICATION IN THE FORM OF OIL-IN-WATER-TYPE EMULSIONS CONTAINING LIQUID FATTY ACID AND FATTY ALCOHOL ESTERS AND PHOSPHOLIPIDS AND THEIR PREPARATION PROCESS

摘要

Oil-in-water cosmetic and dermatological emulsion for topical use contains (wt. %): (1) liquid ester of a fatty acid and a fatty alcohol (I) (8-47), (2) natural phospholipid(s) (II) (5-45), and (3) water (40-80). The preferred composition contains (wt. %): (I) (15-30), (II) (8-30), and water (55-75). An Independent claim is also included for the preparation of the composition comprising: dissolving the hydrophobic adjuvants in the ester and then dissolving the phospholipid in this phase. Separately, the aqueous phase is prepared by dissolving the hydrophilic constituents in water. The aqueous phase and the hydrophobic phase are then mixed.
