CI 42051
Is CI 42051 safe for seborrheic dermatitis?
There is not enough seborrheic-dermatitis-specific evidence to call CI 42051 clearly helpful or harmful. It is added for colour, not to treat the scalp or control Malassezia.
No applicable exact-ingredient human seb derm or Malassezia study was found. Its position in a formula is usually less informative than the cleanser strength, fragrance and other active ingredients, so judge the complete product by how calmly your skin responds.

What is CI 42051 used for in skincare?
CI 42051 is a synthetic colour additive used to give skincare, cleansing and personal-care products a blue or blue-green appearance. Its job is visual consistency and product identity; it does not moisturise, cleanse or act as an antifungal ingredient.
