CITRACONIC ANHYDRIDE

Description

Citraconic anhydride is a versatile organic compound with notable applications in skincare formulations. This colorless liquid, derived from citric acid, is a cyclic anhydride with the molecular formula C5H4O3. Its structural similarity to maleic anhydride contributes to its efficacy in various cosmetic applications.

In skincare, citraconic anhydride functions as a pH adjuster and stabilizer, helping to maintain the optimal acidity of products. It also acts as a chelating agent, binding to metal ions that could potentially destabilize formulations or irritate the skin. This property enhances the overall stability and shelf-life of skincare products.

Notably, citraconic anhydride can be used to modify proteins and peptides, potentially improving their penetration and efficacy in skin treatments. It may also contribute to the formation of film-forming polymers, which can provide a protective barrier on the skin's surface.

While generally considered safe for cosmetic use, formulators should be aware of its potential for skin sensitization in some individuals. As with any active ingredient, appropriate concentration and pH levels should be carefully considered in product development to ensure safety and efficacy.
