About 2,7-Naphthalenediol
2,7-Naphthalenediol is an individual ingredient used in cosmetics.[1] In cosmetics, it is used to color hair.[1] In Europe, it may be used as a coloring ingredient in oxidative hair dyes, at a maximum concentration of 1.0% when the product is mixed immediately before use and applied to the hair.[2] It is described as a yellow powder, so checking first whether it dissolves in water or oil and then dissolving or dispersing it in the appropriate phase can help create a uniform formula.[3]
