Résumé : |
A noble technology concerning a selective penetration of acid dyes has been developed in this study. By this technology, acid dye penetration into hair can be enhanced without enhancing into skin.
It was found that acid dyes could penetrate into hair through only protein region (endocuticle) but could not penetrate into skin unless they diffuse into lipid region (intercellular lipids). A common penetration enhancer, benzyl alcohol (BA), acts on both proteins and lipids. That is the reason why skin is stained by acid dye solution with BA as a penetration enhancer.
From the facts, it was predicted that the substance, which never acted on lipids but strongly acted on proteins, was suitable for the selective penetration enhancing system. We have found out that propylene carbonate (PC) satisfies the request and succeeded to develop the new selective penetration enhancing system with PC. |
