Description

Natural brightening essence and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to natural transparent essence and a preparation method thereof.

Background

The skin is the largest and most easily seen organ of the body and is also the natural barrier of the human body. It can not only reflect the health level of human body, but also reflect the concrete embodiment of "external beauty" of human body. "it is everyone who likes beauty", people have a continuous pursuit for beautifying their own cosmetics since ancient times. Conventional cosmetics are mainly used for skin care, skin cleansing and improvement of skin softness by virtue of their nutritional ingredients and moisture retention ingredients. With the change of living environment and the improvement of living standard of people, the skin care product with special effects such as whitening, anti-wrinkle and dark eye circle removal becomes a hot spot of personal care product industry. And the whitening products are more popular with consumers.

The basal layer cells of the human epidermis contain 4-5% of pigment cells, wherein melanin is a key factor determining the skin color and is also a main reason causing the skin color change. Two different types of melanin also have an effect on the color of the skin. Eumelanin is black or brown in color and is synthesized by tyrosinase. Pheomelanin is orange and is synthesized from tyrosine and cysteine.

The main means of whitening is to inhibit the generation of melanin and interfere the formation and transfer process of melanin. Within melanocytes, including the selective destruction of melanocytes and inhibition of tyrosinase activity; outside of the melanocyte includes interference with transfer of melanosomes, increased degradation of melanin in the keratin cell, and the like. Some substituted phenolic compounds such as hydroxyanisole, hydroquinone, resorcinol, arbutin and the like show specific toxicity to melanocytes; the mercury salt and some protein denaturants have an inhibitory effect on tyrosinase; ascorbic acid has reducing effect, and can prevent dopa generated by tyrosine under tyrosinase catalysis from being oxidized into dopaquinone.

There are many whitening products on the market at present. But the safety and effectiveness of each product are not uniform. Some whitening products have quick response, such as 'a whitening mask', and actually various prohibited components such as dexamethasone, beclomethasone, mercury, hydroquinone and the like are added in most of the products, so that health of consumers is endangered after the products are used. Some approved whitening agents, such as niacinamide, salicylic acid, vitamin C, kojic acid, etc., also cause irritation to the skin. Meanwhile, many products have insufficient moisturizing function, moistening function, maintenance function and whitening function.

At present, the whitening, moisturizing and moisturizing effects of the product are more obvious, and the reason for melanin formation must be comprehensively considered. Therefore, the whitening product with multiple functions, stability and safety is selected to play the role of synergistic whitening, and the whitening product has important significance.

Examples of the experiments

And (4) testing the moisture retention degree: the test principle is as follows: the water content of the horny layer of the human skin is tested by a capacitance method by using a human skin tester. The moisturizing ability of the product was evaluated by measuring the change in the water content of the stratum corneum of the skin before and after the use of the product in example 5 by volunteers.

Experimental example: the product obtained in example 5; control group: certain small bulb whitening essence is sold in the market. The lower jaw part is used as a blank control group, and the blank control group is not coated with any skin care product.

The test method comprises the following steps: selecting 30 volunteers, cleaning face with the same facial cleanser between 20-35 years of age, and smearing the experimental example and the control group products on two sides of the cheek respectively, wherein the smearing amount is kept consistent. The moisture content of the volunteers before and after use is tested by a human skin tester, and the moisture retention performance of the product is evaluated by taking the average value.

As can be seen from the above table, the product prepared in example 5 can significantly increase the moisture content of the skin, and has long moisturizing time and low moisture loss rate.

Cosmetic safety testing:
