Understanding D&C Red 27 Color Changing Pigment

D&C Red 27 Color Changing Pigment (CI45410) is a colorant that changes color based on pH levels.

• When dissolved in oil, it typically appears orange.
• Upon contact with the skin, the pH difference causes it to change to a pink color.

Based on the available information, the characteristic color changes for this pigment are between orange (in oil) and pink (on skin contact). There is no described method or state where this pigment turns completely clear under typical formulation conditions.
