PURPOSE: A hair treatment agent that contains specific amounts of a substance obtained by decomposition of keratin such as keratin hydrolyzate and a silicone derivative such as dimethylsiloxane, thus having high hair-protecting effect. n CONSTITUTION: (A) 0.05W10.0wt% of a keratin decomposition derivative selected from (i) hydrolyzate of keratin, (ii) alkali salt of oxidative decomposition product and (iii) thiol derivative of reductive decomposition product and (B) 0.1W30wt% of a silicone derivative selected from dimethylpolysiloxane, methylphenylpolysiloxane and polyether epoxy, fluorine, alcohol or alkylmodified silicone oil are used to give the objective hair treatment agent. In the agent, component A makes up for the protein which is lost by beauty treatment such as shampooing and component B prevents its eluation, thus showing hair-protecting effect. n COPYRIGHT: (C)1982,JPO&Japio |
