CI 11710

Description

CI 11710, also known as Disodium Red 33 or Acid Red 33, is a synthetic red colorant commonly used in cosmetics and personal care products. This water-soluble dye belongs to the xanthene class of compounds and is characterized by its bright, intense red hue. CI 11710 is approved for use in various countries, including the United States and European Union, for application in rinse-off products such as shampoos, body washes, and facial cleansers.

The colorant is prized for its stability in acidic formulations and resistance to light degradation, making it suitable for a wide range of product types. CI 11710 is typically used in concentrations ranging from 0.001% to 1%, depending on the desired color intensity and product formulation. While generally considered safe for topical use, it may cause skin irritation in some individuals, particularly those with sensitive skin.

Formulators should be aware that CI 11710 can stain skin and fabrics temporarily. It is often combined with other colorants to achieve specific shades and hues in cosmetic products. When incorporating CI 11710 into formulations, it's essential to consider pH levels, as the color intensity can vary depending on the acidity or alkalinity of the product.
