Organic & Artificial Pigment Based Lip Stick & Lip Gloss - How do you intensify their colours?
I am not a Chemist but I am wondering how you increase the ‘pigment intensity’ or ‘payoff pigment’ levels for ‘organic mineral pigment based’ and ‘artificial vibrant colour Yellow 5 & Red 7 based’ Lip Sticks and Lip Gloss? We want our Lip Sticks and Lip Glosses to have a rich / intense look and feel.
ingredient/s do we need to adjust / increase in order to achieve this?
