Help With Formulating Semi Permanent Dye
So I’m working on a formula similar to Iroiro however I cannot find a supplier for the dyes that will ship to a non lab or non business address other than Alibaba or TCI Chemicals and I’m not sure if they are suitable. I’d also like to add that I am well aware of the risks associated with handling dyes. Does anyone know whether acid dyes are ph sensitive like basic dyes? I had found a helpful document on Sensient about the ph ranges for their basic dyes but I’m unsure if that is just for their product or the dye in general. What are the correct usage amounts for these in America? I’d hire a chemist however I’ve had a ton of bad experiences with them and would rather do this on my own.
