A percutaneous absorption promoting agent comprising (A) at least one anionic surfactant and one or two or more of surfactants having a nitrogen atom in the molecule other than anionic surfactants, (B) one or two or more of anionic surfactants and one or two or more of nonionic surfactants not having a nitrogen atom in the molecule, (C) one or two or more of surfactants selected from the group consisting of amphoteric surfactant and semi-polar surfactants and at least one nonionic surfactant having a nitrogen atom in the molecule, (D) one or two or more of surfactants selected from the group consisting of nonionic surfactants, amphoteric surfactants, semi-polar surfactants and cationic surfactants having a nitrogen atom in the molecule, and one or two or more of nonionic surfactants not having a nitrogen atom in the molecule, or (E) an amine oxide as the active ingredient, and a dermatological preparation containing these percutaneous absorption promoting agent and drug components.

Percutaneous absorption promoting agent and dermatologic preparation

A dissolved composition containing (A) one or more of [benzo-1,2,4-thiadiazine]-1,1-dioxide derivatives, (B) dimethyl sulfoxide, benzyl alcohol, or the mixture thereof; (C) water; and (D) one or more anionic surfactants and/or surfactants, other than anionic surfactants, having a nitrogen atom in the molecule thereof, or (D') n-decylmethyl sulfoxide, or (D') (i) one or more ampholytic surfactants and/or nonioni-cationic-polar surfactants and (ii) one or more nonionic surfactants having a nitrogen atom in the molecule thereof and, optionally, (E) isopropyl alcohol and (F) a pH controller. This dissolved composition is effective as an ingredient for a hair germination and hair growth promoting agent.
