PURPOSE: To obtain a safe skin drug for external use capable of providing a semitransparent or transparent state by regulating the concentration of polyols in an aqueous phase by extremely stably emulsifying an oily phase containing a silicone oil and the aqueous phase containing the aforementioned polyols using a specific siloxane derivative as an emulsifying agent.
CONSTITUTION: A skin drug for external use is obtained by blending (A) 5-70wt.% oily phase ingredient containing a silicone oil with (B) 20-94.5wt.% aqueous phase ingredient containing polyols and (C) 0.5-30wt.% emulsifying agent containing a compound expressed by formula I [at least one of R1 to R12 is formula II (Q is 3-20C bifunctional hydrocarbon group; at least one of R13 and R14 is H and the rest is 1-5C hydrocarbon group) and the rest are R16 or XR15 (X is bifunctuonal hydrocarbon group containing ether bond and/or ester bond; R15 is l-30C straight-chain, branched chain or cyclic hydrocarbon group); l to n are numbers of 0 to 2000, R13 and R14 are H) and the rest are CH3] as essential ingredients. The resultant skin drug for external use has the above-mentioned effects.
