α-Arbutin Introduction
α Arbutin, White crystal powder, easily soluble in water,methanol,ethanol,propylene glycol, glycerin without precipitates. Alpha Arbutin also known as 4-Hydroxyphenyl-alpha-D-glucopyranoside, is mainly used to bind to tyrosinase of melanocytes in the skin and inhibit tyrosinase activity. It’s a popular whitening agent in Japan and other asian countries. It mainly use in cream,essence,facial mask for whiten skin and frechles removal. And the ability of α-arbutin to inhibit this enzyme ( whitening effect) is 10 to 15 times than of β-arbutin.Mainly Specifications of Alpha Arbutin
①Alpha Arbutin crystal powder 98% HPLC ②Alpha Arbutin crystal 99.5% HPLC
Benefits of Alpha Arbutin
❶α Arbutin acts as a whitening agent to reduce melanin in the skin. ❷α Arbutin can tighten pores and skin,it can also promote cell growth and help skin wounds heal. ❸α Arbutin also regard as antiseptic and anti-inflammatory ingredients.Typical Specification Sheet of Alpha Arbutin 98%
