Methylsilanol Ascorbate
What is Methylsilanol Ascorbate?
Methylsilanol Ascorbate is a synthetic organosilicon compound formed by linking ascorbic acid, the active form of vitamin C, to methylsilanetriol via an ester bond. This modification creates a lipophilic molecule with enhanced stability against oxidation and pH changes, unlike pure ascorbic acid which degrades quickly. In cosmetics, it falls under antioxidants and skin conditioning agents, appearing in serums, creams, and lotions targeting aging concerns. It works by donating electrons to neutralize free radicals in formulations, preventing rancidity in oils and color shifts in actives, while potentially aiding skin barrier resilience to environmental stressors. The silanol group may improve solubility in oil-based systems and provide a silky feel, facilitating even application without typical vitamin C instability issues. Regulatory databases like CosIng list it for these functions with no major restrictions.
