Description

Tocopheryl Linoleate is a lipid-soluble ester formed from Vitamin E (tocopherol) and linoleic acid, a polyunsaturated fatty acid. This compound is valued for its enhanced stability and delivery properties compared to pure tocopherol, making it a powerful antioxidant and skin-conditioning agent. It is primarily sought after by manufacturers in the cosmetics, personal care, and nutraceutical industries for formulating high-performance anti-aging serums, moisturizers, and dietary supplements.

Application

• Cosmetic & Skincare Formulations: Acts as a primary antioxidant and emollient in anti-aging creams, serums, lotions, and sun care products to protect skin from oxidative stress.
• Hair Care Products: Used in conditioners, hair masks, and serums to improve hair shine, manageability, and provide scalp nourishment.
• Nutraceuticals & Dietary Supplements: Incorporated into softgel capsules and oil-based supplements for its Vitamin E activity and potential health benefits.
• Pharmaceutical Topicals: Serves as an excipient and active ingredient in ointments and creams designed for skin repair and protection.
• Functional Food Additives: Employed as a natural preservative and fortificant in oil-based food products to extend shelf life.
• Advanced Delivery Systems: Utilized in liposomal and nanoemulsion technologies for targeted nutrient delivery in cosmeceuticals.
