3-O-Ethyl ascorbic acid

3-O-Ethyl ascorbic acid is a vitamin C derivative used for antioxidant and brightening functions in cosmetic formulations. Ethyl substitution at the 3-position modifies the ascorbic-acid structure and improves formulation stability relative to unmodified vitamin C under suitable conditions. Its antioxidant activity and influence on pigment-related processes support products for dullness and uneven-looking skin tone.

The ingredient is supplied as a concentrated powder and can be incorporated into compatible water-based cosmetic vehicles. It is distinct from ascorbyl glucoside and from long-chain oil-soluble ascorbyl esters, so their phase requirements differ. The dissolved active is distributed through the aqueous vehicle or emulsion phase, with carrier composition and pH influencing stability and the finished product’s appearance.

Typical Applications

• Brightening vitamin C serums: Used as the vitamin C derivative in facial serums developed for radiance and more even-looking tone. The powder is dissolved in a compatible vehicle to distribute the active throughout the treatment.
• Antioxidant day-care emulsions: Used in face creams and lotions containing an antioxidant active package. It contributes to the skin-care concept alongside moisturizers and, where present, a separately designed UV-filter system.
