Description

Fair, transparent and white facial cleanser and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to fair and bright facial cleanser and a preparation method thereof.

Background

In recent years, as the living standard and aesthetic standard of people are improved, more and more people seek and desire white and moist skin. Therefore, research and development of whitening cosmetics and skin whitening preparations having the effect of preventing color spots and pigmentation caused by solar rays and other causes are receiving increasing attention from cosmetic manufacturers and researchers in various countries, and the whitening cosmetics have become one of the main types of skin care cosmetics. The search for a whitening and freckle-removing preparation which is efficient and has no side effect or little side effect on human bodies becomes a research hotspot in the fields of pharmacy and cosmetics at present.

The whitening product has the main function of whitening the skin by inhibiting the activity of tyrosinase or blocking the oxidation pathway of the tyrosine to generate melanin so as to reduce the generation of the melanin. The skin whitening product is a substance which acts on the skin in the processes of melanin generation and metabolism, inhibits the generation of melanin and meets the specification, but the traditional skin whitening product usually adopts chemical substances, such as mercuric salt with whitening effect and hydroquinone with freckle removing effect. Although the compounds have the effect of quickly whitening skin, the compounds have toxic and side effects on skin, and can cause contact dermatitis or permanent decoloration after long-term use, and the compounds are forbidden in many countries. The currently required skin lightening agents should meet two criteria: firstly, the tyrosinase activity is inhibited at a high rate, and the generation of melanin can be obviously reduced; secondly, the safety is higher, and the skin of the human body is nontoxic and non-irritant. Arbutin, VitC derivatives and kojic acid are the whitening components which are commonly used in the whitening cosmetics at home and abroad at present. In order to develop cosmetics that meet the requirements of "returning to nature", particularly whitening products that are safe and free of side effects, some natural plant ingredients having a good whitening effect are currently being regarded by consumers more and more. The search for and development of natural plant skin whitening and freckle removing preparations which are efficient and have no side effects or small side effects on human bodies has become a more important subject in the field of cosmetics at present.

Chinese patent application CN105640841A discloses an anti-aging and freckle-removing mask liquid and a preparation method thereof, wherein the anti-aging and freckle-removing mask liquid comprises the following components: water, glycerin, propylene glycol, arbutin, sodium polyglutamate, cyclomethicone, dimethicone crosspolymer, 3-O-ethyl ascorbic acid, ammonium acryloyldimethyl taurate/VP copolymer, Agaricus campestris extract, Citrus sinensis flower extract, Iris communis extract, snow lotus herb extract, carbomer, triethanolamine, sodium hyaluronate, methylparaben, phenoxyethanol, and essence. The facial mask liquid has effects of moisturizing, removing color spots, and whitening skin.

Chinese patent application CN105832608A discloses an anti-aging whitening facial cleanser and a preparation method thereof, the anti-aging whitening facial cleanser is prepared by dahurian angelica root, pilose asiabell root, balsam pear, rose, white paeony root, peony, carrot, winged euonymus twig, himalayan teasel root, lotus root, coconut oleic acid monoethanolamide, triethanolamine, polysorbate, squalane, hyaluronic acid, hydroxypropyl methyl cellulose and glycerin monostearate, the dahurian angelica root, the pilose asiabell root, the balsam pear, rose, white paeony root, peony, carrot, winged euonymus twig, teasel root and lotus root are respectively cleaned, aired, crushed and mixed, the mixture is added into an ethanol-water solution for extraction, the extract liquid is concentrated and evaporated under a vacuum environment, then the hydroxypropyl methyl cellulose is added for stirring, the rest raw materials are sequentially added, the mixture is fully stirred and emulsified. The facial cleanser disclosed by the invention is high in safety and good in skin cleaning effect, has good effects of resisting oxidation and delaying skin aging, promotes facial circulation, improves and repairs damaged skin, enables the facial skin to be fresh and bright, and is whitening and dialyzing.

Whitening is also a care process from the inside out. Firstly, a set of whitening products suitable for the user needs to be selected, and because the whitening components are different, the user preferably uses products of the same brand and the same series theoretically, so that adverse reactions caused by the mutual conflict of different whitening components can be prevented. Aiming at the problems that the cleaning and whitening effects of the whitening facial cleanser on the market are not satisfactory and the skin problem cannot be fundamentally improved, the whitening facial cleanser in the market is necessary to be developed, and the whitening facial cleanser is natural, safe, good in cleaning, moisturizing and whitening effects.
