Using D&C Red Color Changing Pigments in Lip Oil

Yes, D&C Red color-changing pigments like D&C Red 27 and D&C Red 21 can be used in lip oil formulations. These pigments are oil-soluble, which makes them suitable for oil-based products like lip oil.

They work by changing color in response to the pH of the skin. When dissolved in oil, they typically appear as a light orange color and transform into a pink shade upon contact with the skin.

Solubility: These pigments dissolve well in a variety of oils.

Recommended Usage Rate: You can use these pigments at a concentration of 0.1-3% depending on the desired color intensity.

Note: Another pigment found, Color Changing Pigment - White to Red, is designed for foundation/make-up and is dispersible in cream, making it less suitable for a clear lip oil.
