Using D&C Red Color Changing Pigments in Lip Oil

Yes, D&C Red color-changing pigments like D&C Red 21 Color Changing Pigment and D&C Red 27 Color Changing Pigment can be used in lip oil formulations. These pigments are designed to change color when they come into contact with the skin, reacting to the change in pH.

They are soluble in a variety of oils, making them suitable for anhydrous (water-free) formulas such as lip oils. When dissolved in oil, they typically appear as a light orange color and develop a pink shade upon contact with the skin.

Recommended usage rate is typically 0.1-3% depending on the desired color intensity.
