What it is
Methylsilanol mannuronate combines an organosilicon (methylsilanol) component with mannuronic acid, a sugar acid found in alginates from brown seaweed. It is used in skin-care and sunscreen formulas as a water-soluble conditioning agent that helps attract and hold moisture at the skin surface. Such silanol-sugar derivatives are valued for their light, hydrating feel.
