Description

Acid Blue 9 Ammonium Salt, also known as Brilliant Blue FCF or FD&C Blue No. 1, is a synthetic dye widely used in cosmetic and personal care products. This water-soluble compound belongs to the triarylmethane family of dyes and is characterized by its vibrant blue hue. In skincare and haircare formulations, it serves primarily as a colorant, imparting a distinctive blue shade to various products.

The ingredient's molecular structure allows for excellent stability across a wide pH range, making it suitable for diverse formulation types. It exhibits good resistance to light, heat, and oxidation, ensuring color consistency in products over time. Acid Blue 9 Ammonium Salt is typically used in low concentrations, ranging from 0.0001% to 0.01%, depending on the desired color intensity and product type.

While primarily utilized for its coloring properties, this ingredient also possesses mild antimicrobial activity, which can contribute to product preservation. It is generally considered safe for topical use and is approved by regulatory bodies worldwide, including the FDA and EU Commission, for use in cosmetics and personal care items. However, as with any colorant, patch testing is recommended for individuals with sensitive skin or a history of allergic reactions to dyes.
