팔미틴산레티놀 C화학적 특성, 용도, 생산
화학적 성질
95.0-100.5% Absorbance @325 nm ≥0.85%용도
vitamin A palmitate is known as a skin “normalizer.” It acts as an antikeratinizing agent, helping the skin stay soft and plump, and improving its water-barrier properties. Because of its impact on the skin’s water-barrier properties, it is useful against dryness, heat, and pollution. It is also an anti-oxidant and is suggested for use in sunscreens. Clinical studies with vitamin A palmitate indicate a significant change in skin composition, with increases in collagen, DnA, skin thickness, and elasticity. Vitamin A palmitate’s stability is superior to retinol.일반 설명
Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to pharmacopeia primary standards.Retinyl palmitate belongs to a category of compounds called retinoids, which are chemically similar to vitamin A. It exhibits a beneficial effect on vision, skin and immune function, inhibits cell proliferation and prevents cancer. It is an important dietary as well as a therapeutic compound.
Safety Profile
Mildly toxic by ingestion. An experimental teratogen. Experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.Purification Methods
The palmitate is separated from retinol by column chromatography on water-deactivated alumina with hexane containing a very small percentage of acetone. It is also chromatographed on TLC silica gel G, using pet ether/isopropyl ether/acetic acid/water (180:20:2:5) or pet ether/acetonitrile/acetic acid/water (190:10:1:15) to develop the chromatogram. It is then recrystallised from propylene at low temperature (below -47o). [Beilstein 6 IV 4135.]팔미틴산레티놀 준비 용품 및 원자재
