preparation example Construction

[0069] The preparation method of the whitening cream containing pearl peptide provided by the present invention is: heating water, glycerin, ammonium acryloyldimethyltaurate / VP copolymer to 70-75°C to dissolve, as the water phase, polyglycerol-3 formazan Glucose distearate, squalane, synthetic jojoba oil, and cetearyl alcohol are heated to 70-75°C to dissolve and used as the oil phase; add the oil phase to the water phase, stir continuously, and dissolve completely , lower the temperature to 45°C, add phenoxyethanol and stir to dissolve, then lower the temperature to 40°C, add pearl peptide and stir to dissolve, then add the rest of the whitening agents one by one, stir evenly, the temperature drops to 35°C and discharge to obtain whitening cream.

[0070] The preparation method of pearl peptide provided by the invention is:

[0071] (1) Decalcification: Pearl powder is weighed, slowly add lactic acid solution according to the ratio of 1g pearl powder (nano-grade pearl powder)...

Embodiment 1- Embodiment 6

[0078] The formula of the whitening cream containing pearl peptide in embodiment 1-embodiment 6 is as shown in table 1.

[0079] The formula of the whitening cream in table 1 embodiment 1-6

[0080]

[0081] Carry out whitening effect verification to the whitening cream prepared in embodiment 1-6:

[0082] 1. Test principle (refer to the test method of cosmetic whitening and freckle removal efficacy of Zhejiang Health Products and Cosmetics Industry Association):

[0083] Changes in skin color can be measured using a skin complexion measuring instrument. The currently widely used measurement method for quantifying skin color is to quantify skin color by the three primary color stimulus values ​​(L*, a*, b*) stipulated by the International Commission on Illumination (CIE). This method is more accurate in quantification and can reflect skin color. Spatial multidimensional variation makes the quantification of skin color more reliable. The test indicators are skin melanin c...

Abstract

The invention discloses a whitening cream containing pearl peptides. The whitening cream comprises, by mass, 52-84 % of water, 1-9% of a humectants, 0.1-0.8 % of a thickening agent, 1-5% of an emulsifier, 2-5% of a skin conditioner, 3-9% of an emollient, 0.1-1 % of a preservative, 2-5% of pearl peptides, 1-3% of oriental cherry extract, 1-2% of Prunus zippeliana extract, 0.2-1 % of undecylenoyl phenylalanine, 1-2% of Griffonia Seed extract, 1-2 % of ergothioneine, 1-2% of Saccharomyces cerevisiae extract and 1-2% of kojic acid dipalmitate. A good synergistic effect is achieved, so that a goodwhitening effect is achieved; and the whitening component in the whitening cream is mainly prepared by compounding the pearl peptides with various plant extracts, so that the irritation to the skin isreduced while the whitening effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, in particular to a whitening cream containing pearl peptide. Background technique [0002] In recent years, with the improvement of people's aesthetic level of skin appearance, whitening cosmetics have been favored by more and more oriental women. Whitening products currently on the market are mainly divided into two categories: 1. Physical whitening products. These products physically disperse white or light-colored fillers in them, and evenly cover the skin surface during use. Due to the refraction and reflection of light, Can achieve the effect of temporarily changing the skin tone. 2. Chemical whitening products, by adding various whitening active ingredients, such as accelerating epidermal renewal, peeling off the melanin that has formed in the stratum corneum; inhibiting the migration of black bodies from melanocytes to keratinocytes. Inhibit the formation of melanin by inhibiting the a...
