Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a moisturizing, hydrating and whitening emulsion and a preparation method thereof.

Background

Healthy and fair skin is a focus of attention of most Asian women, Chinese women advocate the whitening effect of 'skin like snow and skin like grease', and in recent years, the demand of whitening cosmetics is increased along with the improvement of the life quality of people. There are many methods for whitening, such as:

(1) preventing melanin synthesis

Tyrosinase, dopachrome tautomerase and 5, 6-dihydroxyindole-2-carboxylic acid oxidase are the most important biological enzymes in the process of melanin formation, wherein the tyrosinase is the rate-limiting enzyme in the process, the tyrosinase mainly catalyzes the hydroxylation of monophenol to generate a dihydroxy compound and the oxidation of catechol to generate catechol, the two reactions have oxygen radicals to participate, and the activity of the tyrosinase can be damaged by removing the oxygen radicals;

(2) preventing melanin transfer

Azelaic acid, nicotinamide (VB)₃) The skin whitening agent can inhibit the transfer of melanin granules from melanocytes to keratinocytes, thereby having the skin whitening effect;

(3) accelerating melanin metabolism

The vitamin E, the vitamin C and the derivatives thereof can reduce the oxidized melanin particles into white reduced melanin particles, so that the whitening effect is achieved;

(4) oxidation resistant whitening

After being irradiated by ultraviolet rays, active oxygen is generated, so that a phospholipid membrane is damaged, skin tissues are damaged, problems of erythema, pigmentation and the like are caused, pressure is brought to the skin, and more melanin is generated. Anti-oxidation (Anti-Oxidant) is short for Anti-oxidation free radical, a complete set of Anti-oxidation system is arranged in a body, under normal physiological conditions, the body can continuously generate free radicals and continuously remove the free radicals while being subjected to oxidative metabolism, the free radicals and the free radicals are removed in a relatively dynamic balance state in the body, the generation of free radical scavengers of the body is reduced due to aging, unreasonable diet, pressure and the like, excessive free radicals can have harmful effects on the body, the excessive free radicals can attack unsaturated fatty acids in a biomembrane lipid bilayer to cause lipid peroxidation, the structure and function of a biomembrane are changed to cause cell necrosis, the functions of tissues and organs are influenced and aged, the free radicals attack protein to cause the protein to lose functions to cause pathological changes, and if the free radicals occur in collagen tissues, the skin can lose elasticity, free radicals attack DNA, which can cause cutting of DNA strands or base change, cause genetic errors to cause canceration, and reasonable dietary nutrition supplement and exogenous antioxidant nutrient intake can prevent damage of free radicals to cells, delay aging and prevent related diseases.

Superoxide dismutase (SOD) is an important component of an antioxidant enzyme system in a biological system, is widely distributed in microorganisms, plants and animals, can efficiently eliminate free radicals in the body, can cause cell damage and pigmentation due to redundant free radicals in the body, has the effects of accumulating free radicals and clearing obstacles on human body aging, and can whiten skin and delay aging by supplementing exogenous SOD.

Water is the basis of the human body, and the water content in the human body varies according to different development stages. The water content in the fetus is about 90%, the water content in the infant is 80%, the water content in young and old people is 70%, the water content in the middle-aged and old people is 60% or even 50%, and the aging process of people is also the water loss process. The water is a special-effect and cheap cosmetic agent for protecting the skin to be clean, moist and delicate, when the moisture on the surface layer of the skin of a human body is 12-15%, the skin is smooth and elastic, and once the skin lacks the moisture, the skin can be peeled, wrinkles are grown, and the pigmentation is accelerated.

Glabridin is a flavonoid substance, and is known as 'whitening gold' due to its strong whitening effect. The composition is gradually concerned in the beauty industry as the most expensive and safe freckle-removing whitening component in the world. The glabridin can remove a part of tyrosinase from a catalytic ring for melanin synthesis mainly by competitively inhibiting the activity of the tyrosinase, and prevent the combination of a substrate and the tyrosinase, thereby inhibiting the synthesis of the melanin.

Nicotinamide, also known as Nicotinamide (NAA), vitamin B₃Vitamin PP is widely applied to clinical treatment for preventing pellagra, glossitis, stomatitis and dermatitis. It can inhibit the formation of melanin granules, also can inhibit the melanin granules from ascending to cuticle to effectively inhibit the transfer of melanin to cuticle, and when some melanin inevitably reaches the surface skin, the nicotinamide can promote the melanocyte to drop by accelerating the renewal speed of skin cells.

The glucose in L-ascorbic acid-glucoside is linked to the C2 hydroxyl group of vitamin C, and the C2 hydroxyl group is the site of activity of natural vitamin C and the site of decay of vitamin C. Glucose protects vitamin C from high temperatures, acids and bases, metal ions and other mechanical cracking. Compared with common vitamin C, the L-ascorbic acid-glucoside has better solubility and is more stable. It has effects in improving skin color, inhibiting melanin formation, resisting ultraviolet injury, promoting collagen synthesis, and resisting aging.

More than 85% of coconut oil is saturated fatty acid ester, and can reduce water loss through epidermis, moisturize skin, increase skin surface lipid, and soften and moisten skin.

Palmitoyl pentapeptide-3 can penetrate the dermis to increase collagen, and reverse the process of skin aging through the reconstruction from inside to outside. Stimulating the proliferation of collagen, elastic fiber and hyaluronic acid, increasing the water content and water locking degree of skin, increasing the thickness of skin and reducing fine wrinkles.

Ceramide is a phospholipid with ceramide as a skeleton, mainly comprising ceramide phosphorylcholine and ceramide phosphorylethanolamine, is a main component of cell membranes, 40-50% of sebum in the horny layer is composed of ceramide, and the ceramide is a main part of intercellular matrix and plays an important role in keeping the moisture balance of the horny layer. Ceramides have a strong ability to associate with water molecules, and maintain skin moisture by forming a network structure in the stratum corneum.

The small molecular hyaluronic acid has the characteristics of rapid penetration and absorption, can rapidly synthesize the hyaluronic acid of the skin through the action of skin fiber cells, increases the content of endogenous hyaluronic acid, and makes the skin moist and smooth.

Vitamin E is a fat-soluble vitamin, the hydrolysate is tocopherol which is the most main antioxidant, and the vitamin E can effectively resist free radicals, inhibit the generation of lipid peroxide, remove chloasma, inhibit the activity of tyrosinase and reduce the generation of melanin.
