What Is CI 73360?
CI 73360, also known as Pigment Red 181, is a synthetic organic colorant used in cosmetic formulations to provide red and pink hues. It belongs to the class of azo pigments and is manufactured for use in cosmetics rather than pharmaceutical or medical applications.
In skincare products, it functions as a cosmetic colorant to tint formulations. It appears in a relatively small proportion of skincare products overall, typically used in foundations, concealers, and colour-correcting treatments where pigmentation is desired.
How It Works
CI 73360 works by providing visual colour to a formulation through its synthetic pigment structure. When applied to skin in a product base, it deposits colour on the skin surface and can help to optically correct or neutralise unwanted undertones such as redness or sallowness, depending on the product type and intended use.
Clinical Evidence & References
Evidence on CI 73360 in skincare is limited. The available research focuses primarily on adverse reactions associated with permanent make-up applications rather than cosmetic skincare products. Case reports have documented delayed contact dermatitis and inflammatory reactions in some individuals exposed to pigments containing CI 73360, particularly in the context of invasive procedures where the pigment is implanted into deeper skin layers.
It is unclear whether the reactivity observed in permanent make-up contexts translates to topical skincare formulations, where exposure is typically limited to the skin surface and duration is shorter. More research would be needed to establish safety profiles in routine skincare use.

How to Use
If using a product containing CI 73360, apply according to the product instructions. Perform a patch test first, particularly if you have a history of contact sensitivity or reactive skin. Discontinue use if any signs of irritation develop.
