Zusammenfassung: | PROBLEM TO BE SOLVED: To prepare a stable and fine emulsion which does not generate formalin and does not cause pH alteration due to deposition after long time storage by blending polyglycerin ester having a specified formula, alkyl polyglycoxide having a specified formula, and an oil agent. SOLUTION: At the time of producing a fine oil-in-water type emulsion to be used for medical products, cosmetic products, etc., one or more kinds of polyglycerin ester of the formula (in the formula, R1 is a 7-21C straight chain or branched chain, saturated or unsaturated aliphatic group; (m) is an integer of 4-15), an alkyl polyglycoxide having the formula R OGn (in the formula, R is a 8-22C straight chain or branched chain alkyl or alkenyl group; (n) is an integer of 1-4), and one or more kinds of oil agents. In this case, 2-8wt.% of a polyglycerin ester, 0-5wt.% of an alkyl polyglycoxide, and 1-40wt.% of an oil agent are mixed. |
