Citric Acid - CAS 77-92-9

Citric Acid (CAT: R039996) is an alpha-hydroxy acid with exfoliating properties, acting as a pH adjuster and chelating agent. It serves as an exfoliant in skincare products by promoting cell turnover, leading to smoother and more even-toned skin. Its pH-adjusting ability helps balance acidity in cosmetic formulations, enhancing stability. As a chelating agent, it binds to metal ions, preventing unwanted reactions. Citric acid finds applications in the food and beverage industry as a flavor enhancer and preservative. In skincare, it is used in chemical peels, masks, and exfoliating formulations. Additionally, it features in household cleaning products, personal care items, and pharmaceutical formulations.
