Description

Retinyl palmitate (CAS 79-81-2 ) is the ester form of retinol combined with palmitic acid, offering a stabilized, oil-soluble source of Vitamin A for industrial use. It functions as a nutrient source, antioxidant, and skin-conditioning agent across cosmetic, food, and pharmaceutical manufacturing. In cosmetics and skincare, it is incorporated into moisturizers, serums, and anti-aging formulations where it supports skin renewal. It acts as a lipid-soluble antioxidant to protect product integrity and enhance the overall efficacy of topical applications. Food and beverage manufacturers use it to fortify products such as dairy alternatives, infant formula, and margarine to meet regulatory Vitamin A requirements. It is a critical component for ensuring nutritional compliance in large-scale food production. Pharmaceutical producers incorporate it into oral supplements, multivitamin preparations, and topical drug products as a bioavailable retinol source. It also serves nutritional premix manufacturers supplying fortified feed and food ingredient blends at industrial scale. Retinyl palmitate is supplied as an oily liquid, a dry powder, or in oil dispersion form depending on the target application. Standard grades include USP , BP , and food-grade specifications, with potency typically expressed in IU/g. Dry powder forms are available with carriers for easier handling in solid dosage and premix applications. These variations allow for seamless integration into diverse manufacturing processes while maintaining the stability and potency of the active ingredient.
