Vitamin A Acetate CAS# 127-47-9 Retinyl Acetate阅读更多
Retinyl acetate (Vitamin A Acetate) is a yellow prismatic crystal, a lipid compound, and its chemical stability is better than vitamin A. This product or its palmitate is often used clinically dissolved in vegetable oil, and is hydrolyzed by enzymes in the body to obtain vitamin A. The vitamin A recorded in the Chinese Pharmacopoeia is actually vitamin A acetate.
There are two types of vitamin A alcohol: vitamin A1 alcohol, which is retinol, and vitamin A2 alcohol, which is dehydroretinol. Vitamin A alcohol usually refers to vitamin A1 alcohol. The biological potency of vitamin A2 alcohol is 30-40% of that of vitamin A1 alcohol. Its structure is similar to vitamin A1 alcohol, except that it has one more double bond at the C-3 and C-4 positions of the cyclohexene ring.

Vitamin A Palmitate CAS# 79-81-2阅读更多
Vitamin A ester derivatives mainly refer to its alkyl acid esters, such as vitamin A acetate, vitamin A palmitate, etc. Due to the instability of vitamin A, commercial vitamin A is available in the form of its ester. However, vitamin A acetate easily absorbs water and gets damp, while vitamin A palmitate is more stable than vitamin A acetate.
Vitamin A, commonly known as retinol, is an unsaturated monohydric alcohol with an ester ring. It is a yellow flaky crystal or crystalline powder. It is a fat-soluble vitamin. It is insoluble in water and glycerol, and soluble in alcohol, ether, hydrocarbon, Most organic solvents such as halogenated hydrocarbons. Retinol palmitate is an ester of retinol combined with palmitic acid, a saturated fatty acid that is the main component of palm oil. Retinyl palmitate is easily absorbed by the skin and then converted into retinol. It is a yellow or yellow-red solid or oily substance.
