Description

α-Tocopherollinoleate is a lipid-soluble ester derivative of Vitamin E (α-tocopherol) and linoleic acid. This compound is valued for its enhanced stability and bioavailability compared to its parent tocopherol, making it a highly effective antioxidant and skin-conditioning agent. It is primarily sought after by manufacturers in the cosmetics, personal care, nutraceutical, and pharmaceutical industries for formulating high-performance products.

Application

• Cosmetic & Skincare Formulations: Acts as a potent antioxidant and moisturizer in anti-aging serums, creams, lotions, and sun care products.
• Hair Care Products: Used in conditioners, hair masks, and serums to improve hair texture, provide shine, and protect against environmental damage.
• Nutraceuticals & Dietary Supplements: Serves as a source of Vitamin E in softgel capsules and liquid formulations for its antioxidant health benefits.
• Pharmaceutical Topicals: Incorporated into ointments and healing creams for its skin-repair and protective properties.
• Functional Food Additives: Utilized as a natural antioxidant to extend the shelf life of oil-based food products.
• Industrial Antioxidant: Protects sensitive materials in specialty lubricants and polymer applications from oxidative degradation.
