Dunaliella Salina Powder/Beta-Carotene CAS 7235-40-7

Beta-carotene is an orange fat-soluble compound (soluble in acetone, chloroform, petroleum ether, benzene and vegetable oils, insoluble in water, propylene glycol, glycerol, methanol and ethanol).



Beta-carotene is a carotenoid. Beta-carotenecan help clear free radicals, which can reduce lipid peroxidation. Beta-Carotene contains various essential nutrients which is essential for our bodies. Not only does it contain over 60% complete protein, but also contain many other important vitamins and minerals, such as B complex vitamins, vitamin E, carotenoids, iron, manganese, zinc, essential fatty acids such as gamma linolenic acid (which is only found in breast milk). There are three production methods to extract beta-carotene from natural products: plant extraction, salina extraction and fermentation, among which salina extraction and fermentation are the main preparation methods in China. β-carotene is widely used as natural pigment and nutrient fortifier.


  1. Protects skin from aging and clear free radicals;
  2. Supports skin cell metabolism, which helps prevention of skin diseases such as skin dandruff, keratinization, hard squamous epidermal cells, and xeroderma of keratinous hematoma;
  3. Protect eyes from strong light and ultraviolet radiation damage, and helps prevention of night blindness, dry eye, corneal ulcers and keratomalacia;
  4. As natural colorant.
