Description

3-o-Ethyl-L-Ascorbic Acid is a highly stable, oil-soluble derivative of Vitamin C, designed to overcome the instability of pure ascorbic acid in cosmetic and pharmaceutical formulations. Its primary value lies in its potent antioxidant and skin-brightening properties, which remain effective under a wider range of formulation conditions. This compound is essential for manufacturers in the cosmetics, personal care, and nutraceutical industries seeking advanced, stable active ingredients.

Application

• Cosmetic & Skincare Formulations: As a key active in anti-aging serums, creams, and lotions for its ability to inhibit melanin production and promote collagen synthesis.
• Skin Brightening & Whitening Products: Used in treatments targeting hyperpigmentation, age spots, and uneven skin tone.
• Pharmaceutical Topicals: Incorporated into dermatological preparations for wound healing and skin repair due to its antioxidant activity.
• Hair Care Products: Added to shampoos and conditioners to protect hair from oxidative stress and environmental damage.
• Functional Food & Nutraceuticals: As a stable source of Vitamin C activity in oil-based supplement delivery systems.
• Advanced Material Science: Potential use as an antioxidant stabilizer in polymers and sensitive organic compounds.
