Embodiment 1

[0026] A composition for skin whitening, containing: persimmon leaf extract 9%, ginkgo leaf extract 5%, lotus flower extract 9%, saffron flower extract 5%, pomegranate fruit 9% extract, 9% dogwood fruit extract, 9% licorice flavonoids, 4% nicotinamide, 2% ascorbyl glucoside, appropriate amount of potassium hydroxide, appropriate amount of citric acid, 5% deionized water, 0.2% imidazolidinyl urea, Methylparaben 0.2%, propylparaben 0.1%, and the rest is propylene glycol.

[0027] The preparation process is as follows: dissolve ascorbyl glucoside in deionized water, add potassium hydroxide to adjust the pH value to 6.5~6.8, and set aside; heat propylene glycol to about 70°C, add methylparaben and propylparaben, Stir well; when the solution drops to about 40°C, add persimmon leaf extract, ginkgo leaf extract, lotus flower extract, saffron flower extract, dogwood fruit extract, pomegranate fruit extract, licorice flavonoids, nicotinamide, Stir evenly; add imidazolidinyl urea, stir...

Embodiment 2

[0030] A composition for skin whitening, containing: 7% of persimmon leaf extract, 6% of ginkgo leaf extract, 7% of lotus flower extract, 6% of saffron flower extract, pomegranate fruit 8% extract, 8% dogwood fruit extract, 9% licorice flavonoids, 5% nicotinamide, 2.5% ascorbyl glucoside, appropriate amount of potassium hydroxide, appropriate amount of citric acid, 6.25% deionized water, 0.2% imidazolidinyl urea, Methylparaben 0.2%, propylparaben 0.1%, and the rest is propylene glycol.

[0031] The preparation process is the same as in Example 1.

Embodiment 3

[0033] A composition for skin whitening, comprising: persimmon leaf extract 9%, ginkgo leaf extract 7%, lotus flower extract 5%, saffron flower extract 7%, pomegranate fruit 7% extract, 7% dogwood fruit extract, 6% licorice flavonoids, 5% nicotinamide, 2.5% ascorbyl glucoside, appropriate amount of potassium hydroxide, appropriate amount of citric acid, 6.25% deionized water, 0.2% imidazolidinyl urea, Methylparaben 0.2%, propylparaben 0.1%, and the rest is propylene glycol.

[0034] The preparation process is the same as in Example 1.

Abstract

The invention discloses a composition for whitening skin, which comprises whitening functional components including persimmon leaf extractive, ginkgo leaf extractive, lotus extractive, crocus sativus flower extractivea pomegranate fruit extractive, dogwood fruit extractive, licoflavone, nicotinamide and ascorbyl glucoside. According to the invention, the whitening functional components can act before generating melanin, in the process of generating melanin, and after generating melanin; the purpose of whitening skin is achieved in multiple aspects of inhibiting gene expression of related rate-limiting enzyme synthesized by melanin, inhibiting enzymatic activity of the related rate-limiting enzyme synthesized by melanin, eliminating oxygen free radicals, reducing generated melanin, limiting melanin to transfer towards horn cells and the like; therefore, the composition for whitening skin disclosed by the invention is safe and effective.

Description

technical field [0001] The invention belongs to the field of cosmetics and relates to a composition for skin whitening. Background technique [0002] Fair skin has always been the goal pursued by oriental women, and it is a symbol of beauty. The color of the skin is closely related to the content of melanin in the skin, so the core of whitening the skin is to reduce the content of melanin in the skin to a lower level. [0003] The main process of melanin synthesis is as follows: Under the action of tyrosinase, tyrosine in the human body is first catalyzed and oxidized into dopa and dopaquinone, and dopaquinone then becomes dopachrome. Dopachrome can produce melanin in two ways. The first way is that dopachrome spontaneously decarboxylates and polymerizes into 5,6-dihydroxyindole, which is oxidized to 5,6-dihydroxyindolequinone, and then forms melanin; the second pathway is that dopachrome generates 5,6-dihydroxyindole-2-carboxylic acid under the action of dopachrome tautom...
