Structure:

:

Arbutin (beta-arbutin)is a natural double action whitening agent.

Arbutin (Beta Arbutin) is a new type of skin de-pigmentation and whitening agents, an extract of Bearberry plant which produced by a solid /liquid extraction, an environmentally friendly process .

Arbutin protect the skin against damage caused by free radicals, Arbutin is a skin whitening agent which is very popular in Japan and Asian countries for skin de-pigmentation, Arbutin inhibits the formation of melanin pigment by inhibiting Tyrosinase activity.

Arbutin is very safe skin agent for external use which does not have toxicity, stimulation, unpleasant odor or side effect such as Hydroqinone.The encapsulation of Arbutin constitute a delivery system to potentialize the effect in time. It is a way to incorporate the hydrophilic Arbutin in lipophilic media. Arbutin give three main properties; Whitening effects, anti- age effect and UVB/ UVC filter .

Arbutin in medical use:

Back in the 18th century, Arbutin was first used in medical areas as an anti-inflammatory and antibacterial agent. Arbutin was used particularly for cystitis, urethritis and pyelitis. These uses still until today where natural medicine uses only natural ingredients to treat any disease.

Usage:
Place one part of arbutin in 2-3 parts of deionized water. Heat to 55-60 degree C while stirring, keep for 10 minutes until the solution is clear. Pour the resulting solution into cosmetic preparation before emulsification, mix thoroughly. Then add emulsifier and follow usual procedures.

Rate of arbutin use: 3-7%

Recommendation on use of arbutin:
1. Arbuin is prone to hydrolysis under acidic condition. It shall be used at pH 7.0-7.1.
2. Antioxidant and decolorant are required in cosmetic preparations.
3. Add 0.8-1.0% of azone to enhance dermal absorption
