Ethyl ascorbic acid

Ethyl ascorbic acid (CAS 86404-04-8), also known as 3-O-Ethyl Ascorbic Acid or VCE, is a stabilized ether derivative of Vitamin C used as a skin-brightening and antioxidant active in cosmetic formulations.

Unlike pure ascorbic acid, it maintains stability in aqueous systems while delivering bioavailable Vitamin C to skin tissue. It is a high-demand ingredient among formulators developing advanced skincare actives.

The primary application is in brightening serums and creams, where it targets uneven skin tone and hyperpigmentation in leave-on formulations. It is incorporated into anti-aging products alongside niacinamide or retinol.

These formulations deliver antioxidant protection and support collagen synthesis claims. Toners and ampoules in the K-beauty and prestige skincare segments frequently feature it as a lead active at specific concentrations.

Usage levels typically range from 1% to 3% depending on the desired efficacy. Sunscreen formulations also use it as an antioxidant booster to complement UV filter systems for enhanced skin protection.

Ethyl ascorbic acid is supplied as a white to off-white crystalline powder. It is available in cosmetic-grade specification, the standard for personal care applications, with purity typically at 98% or above.

Packaging is commonly offered in kilogram quantities up to bulk drum supply to serve both development-scale and commercial production needs. This ensures reliable supply chains for global manufacturers.
