• Description: Retinyl acetate (retinol acetate, vitamin A acetate) is a natural form of vitamin A. It is the acetate ester of retinol. It consists of yellow crystals which are greasy or sticky. It has a mild, characteristic odor. It has potential antineoplastic and chemo-preventive activities. It can be used to fortify food with vitamin A. As vitamin A acetate can induce cell differentiation and inhibit cell proliferation, it is used in skin-conditioning agent.
• Uses: vitamin precursor Essential micronutrient Retinyl acetate has been used: a control diet to study its effect at different developmental periods in fish larvae to study its inhibitory effects on Mycobacterium avium?subspecies?paratuberculosis?(MAP) strains as an internal standard in high performance liquid chromatography (HPLC) to quantify vitamin A in fortified milk
