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.   Specifications of Vitamin A Acetate Test/Observation Specifications Result Assay  Content HPLC 97%-102% 99.12% Appearance Fine Powder Complies Identification IR.UV Complies Odor Characteristic Complies Mesh 100% pass 100 mesh Complies Residue on ignition MAX 0.1% Complies Loss on drying % MAX 0.5% 0.39% Ash % MAX.1.0% 0.52% Heavy metals PPM MAX.0.002% Complies Limit of Isotretinoin MAX5.0% 3.9% Organic Volatile Impurities Meet The Requirements Complies Microbiology Total Plate Count Yeast & Mold E.Coli Salmonella   <1000cfu/g <100cfu/g Negative Negative   82cfu/g Negative Complies Complies  Conclusion Conform with specification Function of Vitamin A Acetate  1.Vitamin A acetate can effectively prevent obesity, keep women slim figure.2.Vitamin A acetate is used to promote bone growth, help teeth growth, regeneration.3.Vitamin A acetate can adjust the skin and cuticle metabolic effect, can be anti-aging, and to wrinkles.4.Vitamin A can help protect skin, mucous membrane from bacteria violations, healthy skin, prevent skin cancer.5.Vitamin A acetate also can prevent nyctalopia, eyesight decline, the treatment of various eye disease, make the woman good eyes.6.Vitamin A acetate can reduce sebaceous overflow and make the skin elasticity, and at the same time, desalination spot, smooth skin
