CI 51319

Description

CI 51319, also known as Phloxine B or D&C Red No. 28, is a synthetic red dye commonly used in cosmetics and personal care products. This water-soluble colorant belongs to the xanthene class of dyes and is characterized by its vibrant pink to red hue. CI 51319 is primarily utilized in lip products, blushes, and other color cosmetics to impart a rich, long-lasting color.

The dye is approved by the FDA for use in cosmetics and externally applied drugs, with specific restrictions on its concentration in lip products. CI 51319 exhibits good stability in various formulations and resists fading when exposed to light. Its molecular structure allows for efficient binding to proteins, contributing to its color retention properties on the skin and lips.

While generally considered safe for topical use, some individuals may experience sensitivity or allergic reactions. As with any cosmetic ingredient, patch testing is recommended for those with sensitive skin. Formulators should be aware of regulatory limitations and potential interactions with other ingredients when incorporating CI 51319 into skincare and cosmetic products. Its use is restricted or prohibited in certain countries, so manufacturers must ensure compliance with local regulations when formulating for international markets.
