Ascorbyl Methylsilanol Pectinate

What is Ascorbyl Methylsilanol Pectinate?

Ascorbyl Methylsilanol Pectinate is a synthetic cosmetic ingredient formed by esterifying ascorbic acid, or vitamin C, with methylsilanol—a bioavailable organic silicon compound—and pectinate, a polysaccharide derived from pectin in fruits such as apples and citrus peels. This complex creates a lipophilic, water-soluble structure that resists degradation from light, heat, and air. Primarily featured in serums, creams, and lotions within anti-aging and protective skincare lines, it operates through its ascorbic acid core to scavenge reactive oxygen species, safeguarding formulation components and skin surface lipids from oxidative breakdown. Its pectin-silanol matrix also modulates flow properties, ensuring smooth consistency, even suspension of particles, and enhanced sensory feel during application.
