Freckle-removing whitening cosmetic and preparation method thereof

Abstract

The invention relates to a freckle-removing whitening cosmetic and a preparation method thereof. The freckle-removing whitening cosmetic comprises the following raw materials in parts by weight: 1-3 parts of hydroxyethyl acrylate-sodium acryloyldimethyl taurate copolymer, 5-20 parts of moisturizer, 5-15 parts of licorice extract, 4-7 parts of hydrogenated polyisobutene, 1-2 parts of sodium azone phosphate, 0.5-1.5 parts of cetearyl alcohol, 3-8 parts of kojic acid and kojic acid palmitate glyceryl cocoate and the balance of deionized water. The preparation method comprises the following steps: heating the deionized water and the moisturizer; and adding the hydroxyethyl acrylate-sodium acryloyldimethyl taurate copolymer, the hydrogenated polyisobutene and cetearyl alcohol and the licorice extract. In the freckle-removing whitening cosmetic and the preparation method thereof provided by the invention, the tyrosinase and the generation of melanin can be effectively inhibited to prevent new pigmentation, the non-uniform distribution and accumulation of melanocytes on the skin surface are reduced, and the aims of freckle removal and whitening are achieved while guaranteeing safety and avoiding toxic and side effects.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a freckle-removing and whitening cosmetic and a preparation method thereof. Background technique [0002] There are many reasons for the formation of facial pigmentation and complex types, mainly including genetic factors, ultraviolet radiation, endocrine factors, living habits and other stimuli that increase the activity of free radicals. During the process of free radicals attacking and destroying cells, a large number of cells die And the metabolic disorder leads to the inability to metabolize the impurities in the cells, resulting in the deposition of melanin. The number of new cells is greatly reduced to form facial spots, and the new cells are an important factor for whitening the skin. According to reports, in the biosynthesis of melanin, the role of tyrosinase is very important: melanin bodies generate melanin under the action of tyrosinase, and when melanin is produced...

AI Technical Summary

Problems solved by technology

However, most of the freckle-removing and whitening cosmetics currently on the market add depigmentation agents or bleaching agents, and depigmentation agents usually have complex formulas and / or are toxic to a certain degree, and the addition of too much depigmentation agents will cause many people to produce symptoms such as allergies; Bleach will destroy the sebum membrane on the surface of the skin. If the skin is stimulated by factors such as ultraviolet radiation and endocrine disorders again, the melanocytes in the skin will release more melanin, which will cause more serious pigmentation.

Based on this, there is no generally accepted safe and effective freckle-removing and whitening cosmetic on the market; it is particularly important to develop healthy, safe and effective freckle-removing and whitening cosmetics.
