CI 19140
Is CI 19140 safe for seborrheic dermatitis?
CI 19140 is not automatically unsafe for seborrheic dermatitis, but there is not enough relevant ingredient-specific evidence for a broad recommendation. It is used to colour a product or in hair-dye contexts, not to improve the skin condition.
A colourant offers no seb derm treatment benefit, so people with very reactive skin may prefer simpler formulas when possible. The checked sources provide no yeast-specific finding. If a coloured product repeatedly causes itching, burning or redness, discontinue the whole product.

What is CI 19140 used for in skincare?
CI 19140 is used to give cosmetics colour and may appear in hair-dye applications. Its purpose is visual rather than moisturising, cleansing or therapeutic. The surrounding formulation and intended use determine exposure and are more important than the colourant name alone.
