Arbutin, originally derived from natural green plants, is a skin whitening active substance that combines the concepts of "green", "safe", and "efficient". Arbutin is an ideal whitening agent for whitening cosmetics, with two optical isomers: α The isomer with biological activity is a type of isomer. At room temperature, it is a white powder that is easily soluble in water, ethanol, and aqueous solutions of glycerol. It is added to many whitening and skincare products. It is named after its discovery from the leaves of the genus Ursa in the family Rhododendron. Later, it was found in the leaves of plants such as the Vaccinium in the family Rhododendron, the Pear tree in the family Rosaceae (Western pear, small mountain pear), and the Tiger Ear Grass in the family Tiger Ear Grass. After extraction, it is used as a medicinal and cosmetic additive.
Application:
Alpha-Arbutin is Arbutin introduces a glucose molecule into the molecule, which reduces the stimulation effect, and has the ability to
interfere with melanocytes and dilute the formed melanin. , has a very good curative effect.
Alpha-arbutin, similar to arbutin, can inhibit the production and deposition of melanin, and remove pigmentation and freckles.
Studies have shown that alpha-Arbutin can inhibit the activity of tyrosinase at a relatively low concentration, and its inhibitory effect
on tyrosinase is better than that of arbutin, but the price is slightly higher.
Alpha-Arbutin is recommended for whitening creams, lotions and masks.
