ACID RED 33

Description

Acid Red 33, also known as D&C Red No. 33, is a synthetic colorant widely used in cosmetic and personal care products, particularly in haircare formulations. This water-soluble dye belongs to the xanthene class of compounds and is characterized by its vibrant red-pink hue. Acid Red 33 is approved by the FDA for use in cosmetics and externally applied drugs, making it a popular choice for hair dyes, shampoos, and conditioning treatments.

The colorant exhibits excellent stability across a wide pH range and demonstrates good light fastness, ensuring long-lasting color in hair products. Its molecular structure allows for effective binding to hair fibers, providing consistent and uniform coloration. Acid Red 33 is often combined with other dyes to create custom shades and enhance color depth in haircare formulations.

While generally considered safe for use in cosmetics, some individuals may experience skin irritation or allergic reactions. As with any colorant, patch testing is recommended before widespread application. Formulators should adhere to regulatory guidelines regarding maximum concentration limits to ensure product safety and compliance.
