Functions
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Viscosity Controlling
Moisturizing
Antimicrobial
Improves Elasticity
Creates protective layer
Controls product thickness
Traditional Use
A modern polysaccharide developed in the 1970s by the bacterium Sphingomonas elodea. Introduced to cosmetics as a natural-origin thickener and gelling agent to replace synthetic polymers and improve texture in skincare products.
