W/O-TYPE EMULSION PREPARATION HAVING HIGH WATER CONTENT AND CONTAINING MODERATELY POLAR AND/OR NONPOLAR LIPID, ONE OR MORE A-O-B-O-A-TYPE SURFACE-ACTIVE POLYETHER AND ONE OR MORE SUBSTANCE SELECTED FROM CATIONIC POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a W/O-type emulsion having high water content and useful for cosmetic, etc.;SOLUTION: The W/O-type emulsion contains (a) ≥70 wt.% water and optionally a water-soluble substance in total and ≤20 wt.% lipids, emulsifiers and oleophilic components in total based on the total weight of the preparation, (b) a lipid phase having a total polarity of 20-45 mN/m, (c) at least one kind of surfactant selected from polyethers composed of an oligomer or polymer molecule unit B derived from a 3-25C branched or non-branched α,ω-alkylene glycol (α,ω-dihydroxyalkane) and two units A composed of polyoxyethylene group (the molecular units A and B are bonded through ether groups under the scheme of A-O-B-O-A) and (d) at least one kind of substance selected from cationic polymers.;COPYRIGHT: (C)2002,JPO
