Ingredient review
Fragrance Allergen Blend
INCI: F.I.L. c52879/1
This is a regulatory marker for fragrance allergens, not a single ingredient; it signals potential sensitizers in scented products.
In plain English
F.I.L. c52879/1 is a code used by the cosmetics industry to identify a specific blend of fragrance allergens that must be listed on product labels under EU regulations. It doesn't describe a single cosmetic ingredient but rather a mixture of known sensitizing compounds found in many perfumes and scented skincare. For everyday users, seeing this on a label means the product contains fragrance components that could cause allergic reactions in sensitive individuals.
