ACID BLUE 74

Description

Acid Blue 74, also known as Indigo Carmine or FD&C Blue No. 2, is a synthetic dye widely used in the cosmetic and personal care industry. This water-soluble compound belongs to the indigoid family of dyes and is characterized by its intense blue color. In haircare formulations, Acid Blue 74 serves as an effective colorant for shampoos, conditioners, and hair dyes.

The molecule exhibits excellent stability across a wide pH range, making it suitable for various hair product formulations. Its color-fastness properties ensure long-lasting results in semi-permanent and temporary hair coloring applications. Acid Blue 74 is particularly valued for its ability to create vibrant blue hues and contribute to the achievement of cool-toned shades in hair dyes.

Safety assessments have shown that Acid Blue 74 has a low risk of skin irritation and sensitization when used at appropriate concentrations in haircare products. However, as with any colorant, patch testing is recommended before use. The ingredient is approved by regulatory bodies in many countries for use in cosmetics and personal care products, including the FDA in the United States and the European Commission in the EU.
