Embodiment 1

[0026] Example 1 Experimental method and whitening function evaluation

[0027] 1. Sample preparation

[0028] The herbal medicinal materials were dried overnight in an oven, crushed and sieved through a 40-mesh sieve, added with distilled water, and extracted 3 times by traditional steaming, 2 hours each time. Combine the extracts, let stand and filter. The filtrate was concentrated under reduced pressure and placed. In addition to precipitation, the supernatant was eluted with D101 macroporous resin, and the 70% ethanol eluate was collected, concentrated under reduced pressure and dried, and dried to obtain an extract. The extract composition was made into a sample solution with a concentration of 1%, and the following experiments were carried out.

[0029] 2. Determination of inhibition of tyrosinase activity

[0030] Add samples according to the table below, without adding tyrosinase, and use 1% arbutin as a group of samples for comparison. Put the solution in a water...

[0058] Embodiment 3 whitening cream

[0059] Table 3 provides the whitening cream formula containing the plant extract composition, and the dosage of each substance is represented by mass fraction.

[0060] Table 4

[0061]

[0062]Preparation: Mix polydimethylsiloxane, isopropyl palmitate, glyceryl caprylate, monoglyceride, stearic acid, white oil, methylparaben and propylparaben in the formula table , heated to 80°C, melted and stirred evenly, and used as the oil phase; mixed 1,3-butanediol, carboCA, sodium hyaluronate, trehalose, and deionized water in the formula table, heated to 85°C, and stirred Dissolve evenly, as the water phase. Add the oil phase and water phase to the emulsification pot, stir evenly, emulsify and homogenize for 3 minutes, stir and cool to 50°C, add aminomethyl propanol, emulsify and homogenize for 1 minute, add essence and whitening complex liquid, Stir evenly, cool to 38°C, it becomes whitening cream.

Abstract

The invention discloses a whitening plant extract combination and an application of the whitening plant extract combination in cosmetics. The plant combination is prepared by mixing a cortex mori extract, a liquorice extract, a peony extract, a kapok extract, an angelica sinensis extract and a cortex moutan extract. The plant combination can be applied to a whitening formula and has the functions of inhibiting the activity of monophenyl oxidase, clearing radicals and whitening the skin.

Description

technical field [0001] The invention relates to a whitening plant extract composition and its application in cosmetics, belonging to the application field of natural products. Background technique [0002] Tyrosinase widely exists in microorganisms, animals, plants and human body, and is the key enzyme of melanin synthesis in organisms. It is also closely related to human aging, dark spots and color spots. Tyrosinase is a key enzyme in melanin synthesis, and its abnormal overexpression can lead to pigmentation diseases in humans. Therefore, tyrosinase inhibitors can treat the current common pigmentation. Such as freckles, chloasma, age spots, dull complexion, sallow and other bad skin. At present, most of the tyrosine inhibitors added to whitening cosmetics on the market are chemical compounds with obvious toxic and side effects. Therefore, it is of great significance to develop a safe natural plant whitening agent without any toxic and side effects in the development of ...
