Sodium Alginate is a naturally derived polysaccharide extracted from brown seaweed, widely utilized in cosmetic formulations for its exceptional gelling, thickening, and stabilizing properties. In skincare, Sodium Alginate serves as a film-forming agent, creating a protective barrier on the skin’s surface that helps retain moisture and delivers a smooth, silky feel. Its ability to form hydrogels makes it an ideal component in facial masks, where it aids in delivering active ingredients and enhances skin hydration.
In hair care, Sodium Alginate functions as a viscosity enhancer and stabilizer in shampoos and conditioners, contributing to the product’s consistency and ease of application. It also imparts a conditioning effect, leaving hair feeling soft and manageable. Additionally, its film-forming capability can provide a protective coating on hair strands, helping to reduce frizz and improve shine.
