Vitamin A acetate, chemical name as retinol acetate, is the earliest vitamin being discovered. There are two types of Vitamin A: one is retinol which is the initial form of VA, it only exists in animals; another one is carotene.
Retinol can be composited by β-carotene coming from plants. Inside the body, under the catalysis of β-carotene-15 and 15′-double oxygenase, β-carotene is transformed into ratinal which is returned to retinol by the performance of ratinal reductase. Thus β-carotene is also called as vitamin precursor.

Vitamin A acetate (retinol acetate) is the earliest discovered form of vitamin A. In the body, it plays an essential role in visual health, bone development, and maintaining skin and mucosal integrity.
The product comes as a pale yellow free-flowing powder with an assay standard of ≥500,000 IU/g (tested by HPLC), meeting international USP and EP pharmacopeia criteria.
It is easily dispersible in cold water at 15°C to form a homogeneous, stable emulsion, making it ideal for a wide range of formulations.
It helps regulate epidermal keratinization, supports anti-aging and anti-wrinkle action, protects mucous membranes, reduces excess sebum, improves skin elasticity, and supports eyesight health.
We provide 1kg packaging (double plastic bag + aluminum foil bag inside a box) as well as bulk packaging of 10kg, 25kg, or larger quantities packed in sturdy drums or cartons.
Orders under 25kg are shipped door-to-door via express couriers (EMS, DHL, UPS, FedEx) within 3-7 days. Orders over 100kg can be shipped by Air (3-7 days to airport) or by Sea (10-35 days to port).
