WATER-IN-OIL TYPE GEL-LIKE EMULSIFIED COMPOSITION AND EMULSIFIED COSMETIC OR PREPARATION FOR EXTERNAL USE FOR SKIN USING THE SAME

摘要

PROBLEM TO BE SOLVED: To eliminate problems due to such phenomena that softening or melting of blended waxes are caused by a temperature change and an emulsified state is hardly maintained for a long period in a conventional water-in-oil type get-like emulsified composition. ;SOLUTION: This water-in-oil type gel-like emulsified composition comprises (A) an emulsification base of an oligoesterification product obtained by esterifying diglycerol with a 6-22C fatty acid and a 4-10C medium-chain dibasic acid at a reactional molar ratio so as to satisfy X-Z =1, 0.5≤Z/X≤0.95 and 0.2≤Y/(2X+2)≤0.9 when the reactional molar ratios of the diglycerol, the 6-22C fatty acid and the 4-10C medium-chain dibasic acid are X, Y and Z, (B) an oily phase base which is an oily ingredient, containing an ester without any free hydroxyl group and having ≥2.5 permittivity and (C) an aqueous phase base which is an aqueous solution containing 0.1-10wt.% water-soluble organic acid and/or its salt or an inorganic salt at pH3-10 and satisfies (3/1) to (1/50) weight ratio of the ingredients A/B and (5/1) to (1/10) weight ratio of the ingredients (A and B)/C. Furthermore, the emulsified composition is mixed with an oily ingredient, or an aqueous ingredient is then added to the resultant mixture and emulsified to afford a water-in-oil type emulsified cosmetic or preparation for external use for skin.;COPYRIGHT: (C)1998,JPO
