Arbutin refers to an active substance extracted from the leaves or fruits of the bearberry. Beta Arbutin Powder is a white and slightly yellowish powder at room temperature. It is easily soluble in water, methanol, ethanol, propylene glycol, and glycerin aqueous solutions. There is no precipitation after dissolution, and it is insoluble. It is a skin depigmentation component that integrates green plants, safety, reliability, and high-efficiency depigmentation in chloroform, ether, petroleum ether, etc.
It has the effect of brightening the skin, can quickly penetrate into the skin without affecting the skin cells, combine with tyrosine that causes melanin production, and can effectively block the activity of tyrosinase and the effect of melanin. Generate, accelerate the decomposition and elimination of melanin. In addition, arbutin can protect the skin from free radicals and has good hydrophilicity. Therefore, it is often added to commercially available whitening products, and is especially popular in Asian countries.
According to different structures, arbutin can be divided into α type and β type, both of which have the effect of inhibiting tyrosine enzymes to achieve whitening. The most used type is Beta Arbutin Powder, which has been studied in detail; and it is said that α type is added to β type. One-ninth concentration can inhibit the production of tyrosinase and achieve whitening effect, but detailed toxicological studies have not yet been seen. Many skin care products with alpha arbutin claim that it has a whitening effect that is ten times higher than that of traditional arbutin. However, the actual effect has not been confirmed by clear data and experimental reports, but the whitening effect is still positive.
