Product Overview

Carboxymethyl chitosan, a water-soluble derivative of chitosan sourced from natural chitin, is utilized extensively in both personal and oral care products due to its multifaceted properties. In personal care, it serves as a film-forming agent and moisturizer, offering skin protection and a softening effect. Its hyaluronic acid-like characteristics make it ideal for applications in skin, scalp, and hair care, where it forms a protective barrier to prevent moisture loss. Furthermore, in oral care formulations, Carboxymethyl chitosan functions as an anti-plaque component in toothpastes and mouthwashes, effectively combating a wide array of microbes, such as Candida albicans and Staphylococcus aureus. This ingredient is recognized for being safe, non-toxic, and hypoallergenic, ensuring it does not irritate or sensitize the skin, even in sensitive areas.
