Description

Glyceryl Ascorbate is a stable, oil-soluble derivative of Vitamin C (L-Ascorbic Acid) formed by esterification with glycerol. This chemical modification enhances its stability against oxidation and broadens its compatibility with lipid-based formulations, making it a highly effective active ingredient for advanced cosmetic and personal care products. It is primarily sought after by manufacturers in the cosmetics, skincare, and nutraceutical industries seeking to deliver the proven antioxidant and skin-brightening benefits of Vitamin C in more stable, non-aqueous systems.

Application

• Cosmetic & Skincare Actives: A key oil-soluble antioxidant and anti-aging agent in serums, creams, and lotions to combat free radicals and promote collagen synthesis.
• Whitening & Brightening Products: Used in formulations designed to reduce the appearance of dark spots and hyperpigmentation for a more even skin tone.
• Anti-Aging Formulations: Incorporated into anti-wrinkle and firming products to protect skin from environmental stressors and support skin rejuvenation.
• Hair Care Products: Added to hair oils and treatments for its antioxidant properties and potential scalp benefits.
• Lipophilic Delivery Systems: Serves as a stable Vitamin C source in anhydrous formulas, oil phases, and encapsulation technologies for controlled release.
• Nutraceutical & Cosmaceutical Blends: Used in advanced dietary supplements and topical preparations that require a fat-soluble form of ascorbic acid.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep container tightly sealed when not in use to minimize exposure to air and moisture.
