Fat-soluble glabridin compound whitening agent and application thereof

Abstract

The invention discloses a fat-soluble glabridin compound whitening agent and application of the agent in cosmetics. The compound whitening agent is prepared from the following active ingredients in byweight percent: 30-50 percent of glycyrrhiza glabra extract, 10-30 percent of tetrahydroxychalcone, 10-30 percent of ubiquinone and 10-30 percent of an endothelin antagonist. The compound whitening agent has main whitening action mechanisms of inhibiting the activity of tyrosinase, inhibiting the activity of DOPA chrome tautomerase and obstructing indole-5,6-quinone polymerization, so that melanogenesis can be obstructed, differentiation of melanophores can be reduced, and the aims of whitening skin, lightening spots and improving dark skin color can be achieved. The compound whitening agenthas a simple and practical formula and a good whitening and spot-lightening effect, is environmentally friendly and safe since natural products are adopted, is mild and nonirritant in use, and can overcome the defect in an existing whitening agent.

Description

technical field [0001] The invention relates to a cosmetic formulation, in particular to a fat-soluble glabridin compound whitening agent and an application thereof. Background technique [0002] The uneven distribution and accumulation of melanocytes on the surface of the skin can lead to dull skin and dark spots. The main pathway leading to the formation of melanin is that tyrosinase converts tyrosine into dopa, which is further oxidized into dopaquinone, and finally forms melanin. Over the years, the cosmetics industry has been constantly seeking technological breakthroughs and is committed to developing safe and efficient whitening ingredients. [0003] Currently common whitening mechanisms and raw materials include: inhibiting tyrosinase activity, such as glutathione and glabridin; complexing copper ions to prevent DHI polymerization, such as phytic acid, kojic acid and their derivatives; reducing melanin, such as VC and its derivatives; accelerate the degradation of ...
