Embodiment 1

[0142] Embodiment 1, a kind of preparation method of the whitening essence with synergistic whitening effect, carry out the following steps successively:

[0143] 1) Weigh 84.6g of deionized water, 0.1g of sodium hyaluronate, 0.1g of xanthan gum, and 0.1g of sodium sulfite, and mix them evenly until no agglomeration occurs.

[0144] 2) Add 1 g of nicotinamide to the product obtained in step 1), stir (400±50 rpm) until the nicotinamide is completely dissolved, and heat it to 80±5° C. to obtain an aqueous phase.

[0145] 3), weigh 1g of glyceryl stearate, 1g of PEG-100 stearate, 2g of dioctyl carbonate, 0.2g of phenylethyl resorcinol, 0.4g of undecylenoyl phenylalanine, and mix Evenly, heat to 80±5°C, stir (300±50rpm) until the solid is completely dissolved in dioctyl carbonate to obtain an oil phase;

[0146] Note: Except for dioctyl carbonate which is liquid, the rest of the ingredients are solid.

[0147] 4) Add the oil phase obtained in step 3) to the water phase obtained ...

Embodiment 2

[0151] Embodiment 2, every 100g whitening essence is made up of the formula of following weight:

[0152] Sodium hyaluronate 0.1g, xanthan gum 0.1g, sodium sulfite 0.1g, nicotinamide 2g, glyceryl stearate 1g, PEG-100 stearate 1g, dioctyl carbonate 2g, phenylethyl resorcinol 0.4g, 0.8g undecylenoyl phenylalanine, 0.5g 1,2-hexanediol, 0.5g p-hydroxyacetophenone, 10g ascorbic acid, 1g hydroxyethylpiperazineethanesulfonic acid, 6g triethanolamine , the balance is deionized water (about 74.5g);

[0153] The preparation method is identical to Example 1.

[0154] The prepared whitening essence is a light yellow solution with the smell of characteristic raw material---ascorbic acid. pH value is 4.8-5.2, heat-resistant (40±1°C, 12 weeks) returns to room temperature with only a slight deepening of the color, cold resistance (-16±1°C, 12 weeks) returns to room temperature with only a slight deepening of the color, viscosity It is 2000-2500cp.

Abstract

The invention discloses a whitening 5D compound with a synergistic whitening effect. The whitening 5D compound is prepared from the following components in parts by weight: 0.5-2 parts of nicotinamide; 0.15-0.40 part of phenylethyl resorcinol; 0.35-0.8 part of undecylenoyl phenylalanine; 4.5-10 parts of ascorbic acid; and 0.45-1 part of hydroxyethyl piperazine ethanesulfonic acid. The invention further provides a whitening cosmetic prepared from the whitening 5D compound with the synergistic whitening effect and a corresponding preparation method of the whitening cosmetic. The whitening effect of the product is enhanced through the combined action of multiple mechanisms, and meanwhile, no obvious irritation is caused to the skin.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a multi-mechanism and multi-active component whitening 5D complex with synergistic whitening effects. Background technique [0002] Whitening and lightening is one of the important demands of the current cosmetics consumer groups, especially the oriental beauty lovers. At present, people have a relatively full understanding of the problem of skin color. The depth of skin color mainly depends on the melanin secreted by melanocytes. Melanocytes are one of the important constituent cells of the skin. They have dendritic protrusions, and the melanin formed in the cells is transported to the stratum corneum cells through the dendritic protrusions. It forms an epidermal unit with keratinocytes at a ratio of 1:36, and exists in the basal layer of the epidermis. Melanocytes form skin color by synthesizing melanin, and can absorb ultraviolet rays to protect the body from ul...
