Working to make a sunless tanning product. I have a working formula that i am happy with. I need help with the colorants. I know oxides don’t play well with DHA. What do I use? DHA take 5 hours to bloom so colors are added to give “instant” satisfaction till the rxn happens. I have contacted a few color suppliers and all do not seem educated on the topic even though most products on the shelf have colorants. Suggestions?
