Description

The present invention is a damage recovery agent that recovers damage to hair and / or skin caused by chlorine, and hair and / or skin used to recover damage to hair and / or skin caused by chlorine. Regarding cosmetics.

In general, tap water used for bathing and water used for swimming pools are mostly chlorinated in order to keep the water hygienic, and contain residual chlorine. For this reason, hair and skin may be damaged by bathing or swimming. Specifically, for example, the hair may become dry or squeaky, the color of the hair may change, the skin may become rough, or the water content of the stratum corneum may decrease. Is concerned.

So far, in order to remove residual chlorine contained in water before affecting the human body, a substance having an excellent residual chlorine removing action has been searched for, for example, residual chlorine removal containing a peach extract. Agents have been proposed (see, for example, Patent Document 1).

On the other hand, after the effect on the human body occurs, that is, after the hair and skin are damaged due to chlorine, it has the effect of recovering it, and a sufficient material is still provided as a highly safe material. The current situation is that it has not been done.

Therefore, it is strongly desired to promptly provide a highly safe material having an action of recovering damage to hair and skin caused by chlorine.
