IIã??Basic introduction of alpha arbutin:
Alpha arbutin is similar to beta arbutin in that it inhibits the production and deposition of melanin and can remove freckles and discoloration, such as beauty. The results showed that alpha arbutin could inhibit the activity of tyrosinase at lower concentration, and its inhibition of tyrosinase was better than that of beta arbutin.
Alpha arbutin is the differential phase isomer arbutin, in recent years found that it is better than arbutin has strong inhibition of tyrosinase, can prevent the formation of melanin, and thus reduce the skin pigment deposition, remove spots and freckles, and on the melanin cell does not produce toxic, stimulating and allergenic effects, as well as the effect of sterilization, anti-inflammatory, thus caused wide attention of the cosmetics market. Alpha arbutin can inhibit the activity of tyrosinase at very low concentration. Although the inhibition mechanism is different from arbutin, its intensity is nearly 10 times that of arbutin, and the cell growth is not affected at high concentration. Since 2002, the European and American markets have promoted alpha arbutin as a safe and effective skin brightening active agent to the high-end cosmetics market, and it is the most ideal skin whitening and freckling active agent in the 21st century.
IIIã??Efficacy of alpha arbutin:
1.It can protect the skin from free radicals;
2.It can anti-aging, anti-uv, whitening skin;
3.It can inhibit the tyrosinase activity and inhibit the formation of melanin;
4.It is a very safe external skin preparation, non-toxic, non-irritating and non-smelly;
5.It can remove pigmentation and is very popular in Japan and Asian countries.
IVã??Application of alpha arbutin:
1.It can be used in the medical field, such as anti-inflammatory drugs, antibacterial agents;
2.It can be used in cosmetic fields, such as skin whitening and sunburn treatment.
3.It can be used to treat allergic skin inflammation.

Melatonin is a hormone produced in the brain by the pineal gland from the amino acid tryptophan. The synthesis and release of melatonin are stimulated by darkness and suppressed by light, suggesting the involvement of melatonin in circadian rhythm and regulation of diverse body functions. Levels of melatonin in the blood are highest prior to bedtime. Synthetic melatonin supplements have been used for a variety of medical conditions, most notably for disorders related to sleep. Melatonin possesses antioxidant activity, and many of its proposed therapeutic or preventive uses are based on this property. New drugs that block the effects of melatonin are in development, such as BMS-214778 or luzindole, and may have uses in various disorders. Function: Improve sleep; Anti-aging; Adjust immunity function; Anti-cancer etc. Test Items Specification Results Appearance White or pale-white crystalline powder White crystalline powder Clarity and degree of opalescence of liquids 1%ethanol and chloroform Solution Conforms Particle size 100-120mesh 200mesh Identification Positive Positive Loss on drying 0.10% MAX 0.05% Sulphated ash 0.1% MAX 0.005% Heavy metal 20 PPM MAX 7PPM Melting point 117-120 degree 118.5 degree Relationed substances Single impurity 1.00% max 0.50%max 0.37% 0.12% Single impurity 0.10% 0.06% Assay (TLC) 98.00%-102.00% 99.50% Assay (HPLC) 98.00%-102.00% 99.35%.
