  • Tyrosinase activity inhibitor and external preparation for skin
    Patent number: 10632089
    Abstract: A tyrosinase activity inhibitor is prepared by combining (A) a metal (zinc, cobalt or iron) chelate compound of ?-lipoyl amino acid or its pharmaceutically acceptable salt with (B-1) a human manganese SOD or (B-2) an ascorbic acid compound such as ascorbic acid and ascorbyl glucoside. A ratio (R1) of the (B-1) component content to the (A) component content is preferably 0.001 to 1,500, when R1 is defined as R1=[Unit concentration of (B-1) component (unit/mL)/Concentration of (A) component (?g/mL)], and a ratio (R2) of the (A) component content to the (B-2) component content is preferably 0.0001 to 1,000, when R2 is defined as R2=[Concentration of (A) component (m/mL)/Concentration of (B-1) component (mg/mL)]. An external preparation for skin contains the (A) component and the (B-1) component or the (B-2) component as effective ingredients for inhibiting tyrosinase activity.
