Composition for hair treatment agent

摘要

A composition for a hair treatment agent comprising as essential components: a chelating agent having a specific chelating value with respect to the chelation of the calcium ion, and a polymer compound selected from a group consisting of cationic polymers containing quaternary nitrogen, and peptides of an average molecular weight of 40 to 10,000, or their derivatives. The composition provides a perm-treatment with a good finishing effect by depressing absorption of calcium to the hair when it is perm-treated. It also serves as a shampoo, by further formulating an anionic or amphoteric surface active agent, which gives an excellent effect of suppleness and smoothness after washing and rinsing to hair which is damaged from a perm treatment.
