PROBLEM TO BE SOLVED: To provide an organic disulfide compound by which excellent performance for permanent wave can be achieved while odor of a reducer is decreased or eliminated, a composition which contains, for example, a dithiodiglycolic acid (DTDGA) to reform a keratin fiber, and preferably a cosmetic composition.SOLUTION: A composition to reform a keratin fiber, or preferably a hair comprises: (a) at least one kind of fatty substance preferably in the form of liquid at ambient temperature under atmospheric pressure; (b) at least one kind of surfactant, or preferably at least one kind of nonionic surfactant; and (c) at least one kind of organic disulfide compound, wherein amount of (a) the fatty substance is 30 mass% of total mass of the composition or more, or preferably 50 mass% or more. The composition contains the organic disulfide compound such as a dithiodiglycolic acid (DTDGA) to be an oily composition, thereby enabling achievement of excellent performance for permanent wave while odor of a reducer is decreased or eliminated.SELECTED DRAWING: None |
