Abstract

The invention relates to a paradimethy-laminobenzaldehyde thiosemicarbazone as tyrosinase restrainer, in particular to the paradimethy-laminobenzaldehyde thiosemicarbazone applied in beauty cosmetics. The invention uses paradimethy-laminobenzaldehyde thiosemicarbazone with high-effect restrain function on the activity of tyrosinase as whitening agent to prepare beauty cosmetics, and provides a relative beauty cosmetics and a preparation. The invention uses paradimethy-laminobenzaldehyde thiosemicarbazone as whitening agent of de-crease beauty cosmetics solution which contains sea fish collagen peptide, paradimethy-laminobenzaldehyde thiosemicarbazone, alcohol, glycerin, methyl glycol, plant essence, conservative and water, that dissolves sea fish collagen peptide into water to obtain solution A, dissolves conservative and paradimethy-laminobenzaldehyde thiosemicarbazone into alcohol to obtain solution B, adds glycerin and methyl glycol into solution B to obtain solution C, mixes the solutions A and C, and adds water to form solution D, and adds plant essence into the solution D.

Description

technical field [0001] The invention relates to a p-dimethylaminobenzaldehyde thiosemicarbazone as a tyrosinase inhibitor, in particular to the application of p-dimethylaminobenzaldehyde thiosemicarbazone as a whitening agent in whitening cosmetics. Background technique [0002] Tyrosinase widely exists in organisms and is the key enzyme of melanin biosynthesis (Mayer AM, Harel E.Phenoloxidases and their significance in fruit and vegetables. Food Enzymology, Fox P F.Ed, Elsevier; London, 1998, 373-398) In living organisms, tyrosinase firstly hydroxylates tyrosine to generate L-DOPA, then oxidizes L-DOPA to generate dopaquinone, and dopaquinone undergoes a series of enzymatic and non-enzymatic reactions to form melanin . Therefore, tyrosinase is the rate-limiting enzyme of melanin synthesis, its activity is related to the amount of melanin synthesis, and the amount of melanin production can be regulated by regulating its activity (Friedman M.Food browning and its prevention:...
