Description

Cosmetic with freckle removing and whitening functions and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to a cosmetic with freckle removing and whitening functions and a preparation method thereof.

Background

With the development of modern society, the rhythm of life of people becomes fast, and the pressure of life is multiplied, and work and rest is irregular, and factor such as environment and diet, human health receives certain influence, and skin is the true picture of human health, is the barrier of human body. Due to the reduction of the activity of an antioxidant system of the body, the reduction of immunity, the exposure of human skin to ultraviolet radiation in the external environment for a long time, air pollution and the like, oxygen free radicals in the body are increased, tyrosinase is increased, the activity is increased, various problems often occur to the skin, and the skin is dry, dull and lusterless, generates color spots and pigmentation and needs to be repaired by cosmetics.

The formation of the stain was as follows: tyrosine in melanocyte tissue is gradually converted by intermediates such as dopa, dopaquinone, dopachrome and dihydroxyindole under the action of tyrosinase and the like, and the melanocyte tissue further transmits melanin to epidermal basal layer cells, generally enters stratum corneum along with the metabolism of cells and finally falls off along with keratinocyte; however, when melanin excessively synthesized remains in the skin and is not discharged to the outside of the skin, pigmentation occurs, which in turn causes stains and accelerates skin aging.

At present, spot-removing whitening products in the cosmetic market are full of line, but most of the products contain components such as a preservative, a bactericide, ethanol, cyclopentadimethicone, synthetic essence, spice and the like, and have excessive non-functional components, so that extra damage is brought to the skin; meanwhile, certain limitation exists in use, for example, cyclopentadimethicone in the product has certain irritation, and cosmetics such as essence with high cyclopentadimethicone content are not suitable for pregnant women, but cyclopentadimethicone is widely used in cosmetics and human body care products as a key component of a solvent, a softening agent and a thickening agent. In addition, the spot-removing whitening cosmetics have limited efficacy retention ability by themselves. Therefore, the development of cosmetics with speckle removing and whitening functions, which have no side effects on human bodies and have lasting effects, becomes a hot spot of research at home and abroad.

Meanwhile, the preparation process of cosmetics is also concerned, and in the commonly used high-speed shearing emulsification step, because the traditional emulsifying machine has poor emulsification effect on materials and does not have the function of multiple shearing when shearing the materials, the materials cannot be completely sheared, the crushed materials are not fine enough, so that the subsequent effect of blending with oil phase is poor, and the quality of the prepared finished product is not high; meanwhile, the traditional emulsifying machine cannot clean the emulsifying tank while shearing and crushing, so that the emulsifying tank is easy to pollute the produced finished product, and the quality of the finished product is poor; moreover, the traditional emulsifying machine does not have the function of preventing the discharge port from being blocked, so that manual dredging is often needed; the emulsified finished product is simple and crude in storage, so that the finished product is easily polluted, and the finished product is easily leaked due to external impact.
