Retinyl acetate (retinol acetate, vitamin A acetate) is a natural form of vitamin A which is the acetate ester of retinol. It has potential antineoplastic and chemopreventive activities.[2][3]
In the United States, retinyl acetate is classified generally recognized as safe (GRAS) in the amounts used to fortify foods with vitamin A.[4][5]
