CI 28440
Is CI 28440 safe for seborrheic dermatitis?
CI 28440 is best considered with the complete coloured cosmetic and its intended use in view. It supplies colour; it has no established role in managing seb derm. The checked EU colourant entry includes purity conditions.
No applicable exact-ingredient human seb derm or independent Malassezia study was established. Permission for a particular cosmetic colourant is separate from personal tolerance, and conditions attached to another dye should not be transferred by analogy. Consider the finished product and avoid repeated use if it causes discomfort; ask for advice about persistent skin reactions.

What is CI 28440 used for in skincare?
CI 28440 is listed as a colourant. Its official EU entry describes a black colouring material and applicable purity criteria. This is a formulation and regulatory role, rather than an anti-inflammatory, cleansing or treatment function. Colour alone does not tell you how the complete product will behave on your skin.
