Verwenden

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.

Allgemeine Beschreibung

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.

Sicherheitsprofil

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.

l?uterung methode

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.]
