  Increasing solubility of oxidative dyes in powder hair color

  Posted by ashish on April 10, 2016 at 11:17 am

  Hi all, I want to enhance solubility of Oxidative dyes like P-aminophenol & M-aminophenol which are poorly soluble in water. Due to poor solubility, hair colour is not able to fulfil the requirement of 100% grey coverage. Problem is that product is in powder form so that aimed ingredient should be in powder form to enhance solubility of oxidative hair dyes. 

  Note - Product is in powder form which is ready to mix with water by consumer.

  Thanks Bill, i am already using anionic surfactants but not getting satisfactory results. I know non ionic surfactants are more preferable for solubility of dyes but problem is that a very few of this kind are available in powder form & moreover they are costlier.
