Description

Ascorbyl Tetraisopalmitate is a highly stable, oil-soluble derivative of Vitamin C (L-ascorbic acid), where the hydroxyl groups are esterified with isopalmitic acid. This chemical modification is critical for its exceptional stability and lipid compatibility, making it a powerful antioxidant for oil-based formulations. It is primarily sought after by manufacturers in the cosmetics, personal care, and nutraceutical industries seeking to enhance product shelf life and deliver antioxidant benefits in non-aqueous systems. Its efficacy and stability make it a key functional ingredient for advanced skincare and wellness products.

Application

• Cosmetic & Skincare Formulations: As a primary antioxidant in serums, facial oils, moisturizers, and anti-aging products to protect against oxidative stress and support collagen synthesis.
• Sun Care Products: Incorporated into sunscreens and after-sun lotions to provide antioxidant protection against UV-induced free radicals.
• Hair Care Products: Used in hair oils, serums, and treatments to protect hair from environmental damage and improve scalp health.
• Nutraceuticals & Dietary Supplements: As an oil-soluble Vitamin C source in softgel capsules and lipid-based supplement blends.
• Color Cosmetics: Added to foundations, lipsticks, and other pigmented products to prevent rancidity and color fading.
• Pharmaceutical Topicals: Used in ointments and medicated creams for its antioxidant properties and potential skin-healing benefits.
