no. 1 approach

[0038] The first embodiment of the present invention provides a whitening cosmetic additive, including: licorice extract and saffron extract. The whitening cosmetic additive of the invention can well inhibit the activity of tyrosinase, and has excellent whitening effect when used in cosmetics, especially in whitening essence stock solution.

[0039] Licorice extract is a medicinal ingredient extracted from licorice. Licorice extract generally contains: glycyrrhizin, glycyrrhizic acid, glycyrrhizin, licorice flavonoids, bistanol, formononetin, quercetin, etc. Licorice extract is a yellow to brown powder, which can scavenge oxygen free radicals, has anti-inflammatory effects, and also has anti-ultraviolet rays, improving rough, dehydrated and inflamed skin.

[0040] Although licorice extract can prevent the formation of melanin by inhibiting the activity of tyrosinase and dopachrome intermutase (TRP-2), hindering the polymerization of 5,6-dihydroxyindole (DH1), thereby Reach t...

no. 2 approach

[0046] The second embodiment of the present invention provides a whitening essence stock solution, including the whitening cosmetic additive of the first embodiment of the present invention. The whitening essence stock solution of the present invention can make water penetrate and flow naturally, and the absorption ability of the skin to nutrients can be improved, so that the skin can be supple and elastic. The present invention can inhibit the activity of tyrosinase by adding the whitening cosmetic additive of the present invention, and has excellent whitening effect.

[0047] In the present invention, based on the total mass of the whitening essence stock solution, the amount of the whitening cosmetic additive is 0.01-10%, preferably 0.1-5%, for example: the amount of the whitening cosmetic additive can be 0.5% %, 1%, 2%, 3%, 4%, 6%, 7%, 8%, 9%, etc. When the addition amount of the whitening cosmetic additive is between 0.01-10%, the melanin content in the skin after using ...

no. 3 approach

[0072] The third embodiment of the present invention provides a preparation method of the whitening essence stock solution of the second embodiment. The method includes the step of mixing the components of the whitening essence stock solution.

[0073] Specifically, the preparation method of the whitening essence stock solution comprises the following steps:

[0074] 1. Add water, some humectants, chelating agents, thickeners, and some preservatives into the emulsification pot, stir and heat to 75-85°C, homogenize for 1-5 minutes, keep stirring for 10-30 minutes and then cool;

[0075] 2. Cool to 40-50°C, add some moisturizing agents, skin conditioning agents, whitening cosmetic additives, soothing agents, pH regulators, bis-PEG-18 methyl ether dimethyl silane in the pre-dissolved moisturizing agent , solubilizer, optional antioxidant, remaining preservative and fragrance are stirred evenly;

[0076] 3. Cool to 30-40°C, discharge, and let stand for 12-48 hours;

[0077] 4. ...

Abstract

The invention provides a whitening cosmetic additive, whitening essence stoste and a preparation method of the whitening essence stoste. The whitening cosmetic additive comprises 0.1%-85% by mass of licorice extract and 15%-99.9% by mass of saffron extract. The whitening cosmetic additive has an excellent inhibiting effect on tyrosinase activity and has no side effects on a human body. Further, the whitening essence stoste adopts a mild formula and can effectively inhibit tyrosinase activity, thereby having the whitening function.

Description

technical field [0001] The invention relates to a whitening cosmetic additive, a whitening essence stock solution and a preparation method thereof, belonging to the field of cosmetics. Background technique [0002] Melanin is mainly produced by melanocytes in the basal layer of human skin epidermis, which can reduce the damage of ultraviolet rays to the skin. The content and distribution of melanin determine the color of the skin. However, the abnormal accumulation of melanin in the basal layer will cause hyperpigmentation and cause melasma, freckles, age spots, etc., affecting people's quality of life. With the deepening of research on melanin biosynthesis, researchers found that tyrosinase plays an important role in melanin biosynthesis. It is the main rate-limiting enzyme in the process of converting tyrosine and dopa to melanin. Its overexpression is the main cause of hyperpigmentation. Therefore, inhibiting the activity of tyrosinase can block the biosynthesis reacti...
