α-Arbutin is a chemical substance. Alpha- arbutin, similar to arbutin, can inhibit the production and deposition of melanin and remove freckles and freckles. The results showed that-arbutin could inhibit the activity of tyrosinase at relatively low concentration, and its inhibitory effect on tyrosinase was better than that of arbutin. Alpha-arbutin can be used as a whitening agent in cosmetics.
The whitening mechanism of α-arbutin directly inhibits tyrosinase activity, thereby reducing melanin production, rather than by inhibiting cell growth or tyrosinase gene expression. Because α-arbutin is a more efficient and safer whitening active substance, many cosmetic companies at home and abroad have used α-arbutin instead of β-arbutin as whitening additive.
The difference between α-arbutin and β-arbutin:
The optical rotation of α-arbutin is about + 180 degrees, while that of β-arbutin is about-60 degrees.Compared with β-arbutin, α-arbutin is more soluble in water and resistant to high temperature, has good photostability, no cytotoxicity in safe dose, and the inhibitory effect of melanin is 10-15 times stronger than that of β-arbutin. α-arbutin can be used in the day time.
α-arbutin is generally used in high-grade whitening cosmetics.
