Description

Retinyl acetate (CAS 127-47-9 ), also known as retinol acetate and vitamin A alcohol acetate, is the acetic acid ester form of vitamin A used as a nutritional supplement and active ingredient across pharmaceutical, food, and cosmetic manufacturing. Its esterified structure offers improved stability over free retinol, making it a preferred sourcing choice for formulators requiring consistent potency through processing and shelf life. In dietary supplements and fortified foods, it delivers measurable vitamin A activity. It is used to standardize nutrient content in capsules, tablets, and fortified staples such as flour, milk, and infant formula. Pharmaceutical manufacturers incorporate it into vitamin A deficiency treatments and multivitamin preparations where precise dosing is critical. Regulatory compliance is ensured through adherence to USP and BP standards. In personal care, it functions as an active in anti-aging creams, serums, and moisturizers targeting skin renewal and moisture retention. Food producers also use it to restore vitamin A levels lost during processing in margarine and cooking oils. Retinyl acetate is supplied as a crystalline powder, oily liquid, or in stabilized beadlet form for dry blending applications. Standard grades include food-grade specifications, with potency typically expressed in International Units (IU) per gram. Beadlet formulations with varying IU concentrations are commonly available to support direct compression or powder mixing. Contact us for supply of Retinyl acetate Request Quote
