Description

A kind of skin cleansing composition and its preparation method and application

technical field

The invention belongs to the technical field of cosmetics, and in particular relates to a skin cleansing composition and a preparation method and application thereof.

Background technique

According to the definition of the "Regulations on the Supervision and Administration of Cosmetics" that will come into effect on January 1, 2021, cosmetics refer to the application of rubbing, spraying or other similar methods to the surface of the human body such as skin, hair, nails, lips, etc. to clean, protect, Daily chemical industry products for the purpose of beautification and modification. my country's cosmetics classification principles are mainly classified according to product functions and parts of use. According to the product function, it is divided into cleaning cosmetics, nursing cosmetics, beauty, and modification cosmetics. According to the part of use, it is divided into cosmetics for skin, cosmetics for hair, cosmetics for nails, cosmetics for lips. Among them, the purpose of cleansing cosmetics is to remove the dirt on the skin, keep the skin fresh, and help maintain the normal physiological state of the skin. And cleansing products are a large category of cosmetics, accounting for more than 10% of the cosmetics market. At present, there are many kinds of cleansing products in the domestic market, and cleansing products are increasingly valued by consumers and manufacturers. People have higher and higher requirements for cleansing products, and the development of cleansing product formulas has become more and more important.

The current common cleansing products include cleansing cream, cleansing milk, cleansing gel (cleansing gel), cleansing foam (cleansing mousse) and so on. The facial cleanser is thick in texture, rich in foam and strong in cleaning power. It also has the effect of removing makeup and can effectively remove isolation and sunscreen products. It is suitable for oily to combination insensitive skin; the facial cleanser has rich foam, more moisture, and is gentler Moisturizing, generally does not irritate the skin; cleansing gel (cleansing gel) is more refreshing and milder than cleansing cream and cleanser, suitable for sensitive and dry skin; cleansing foam (cleansing mousse) because of the advancement of packaging design The rich foam can be directly squeezed out of the pump, the formula is simple, no thickening, low concentration of surface active, mild, refreshing and no residue, suitable for various skin types and seasons. As consumers become more and more critical about the appearance of cleansing products, the market demand for diversified formulations of cleansing products is also increasing.

The formula of cleansing products is mainly composed of water, surfactants, thickeners, moisturizing agents, preservatives, fragrances and other ingredients. At present, the cleansing products on the market can be roughly divided into soap-based and amino acid-based cleansing according to the main surface activity. Soap-based cleansers usually have rich foam, easy rinsing, fresh skin, and strong cleaning power; the disadvantage is that the soap base is alkaline, the degreasing power is too strong, the skin is easy to dry after washing, which is irritating to the skin, and the saponification process during the production process. If the stirring speed and temperature requirements are high, it is difficult to ensure batch stability. Amino acid type cleanser is safe and mild, with moderate cleaning power and smooth skin feel; the disadvantage is that the foam is usually not rich enough, and the fake slippery feeling after washing makes consumers feel that they have not washed clean, and it is difficult to thicken and easily dissolve water. Viscosity was significantly reduced. How to match the formula of a cleansing product to ensure that the product viscosity is stable in the life cycle while taking into account the rich foam, moderate cleaning power, easy rinsing, and low irritation, is another problem that cleansing products need to solve.

Effect Example 5 Transdermal Water Loss Test

Trans Epidermal Water Loss (TEWL), also known as transdermal water loss, indicates the degree of water loss in the dermis through the epidermis through evaporation. The lower the TEWL value, the less water lost percutaneously, and the better the barrier function of the stratum corneum; conversely, the worse the barrier function is. Volunteers using the product were tested using a transdermal water loss tester (Tewameter TM3000).

90 valid volunteers were randomly selected, including 45 male and female, aged between 18 and 45 (except pregnant and lactating women), with no skin problems at the test site within the past month, and no history of systemic diseases. No history of severe allergies to skin care products. Before the test, volunteers were asked to wipe their arms with clean water, sit still for 30 minutes under a constant temperature and humidity environment (temperature: 25±1°C, relative humidity: 40±5%), and keep relaxed. A 4×4cm test area was marked on the inside of the volunteer’s arm at a distance of 5cm from the base of the palm. The same arm can mark multiple areas at the same time (with an interval of 1cm). The test examples and comparative examples are randomly distributed on the left and right arms. The marked area cannot be marked during the test. Apply drugs or cosmetics that are not related to the experiment. For 4 consecutive weeks (each volunteer has 9 test areas, each person uses one sample per area fixedly, once a day), use the same amount (2g) of samples in the marked area of the volunteers, and rub the same number of circles. , rinse and dry naturally. Use Tewameter TM3000 to test and record the transdermal water loss values (TEWEL- _W0 , TEWEL-W1, TEWEL-W2, TEWEL-WEL-W0, TEWEL- _W1 , TEWEL- _W2 , TEWEL- _W4 ), and calculate the change value after 4 weeks ΔTEWEL=(TEWEL- _W4 )-(TEWEL- _W0 ) The test results (the average value of the obtained experimental data) are shown in Table 12: with the increase of the test time, The higher the transepidermal water loss of the volunteers, it shows that different types of cleansing products will damage the skin barrier; it can be seen from ΔTEWEL that the cleansing gels of Examples 1 to 6 of the present invention have a weaker damage to the skin barrier than the skin barrier. The soap-based cleanser of Example 1 and the pearly cleanser of Comparative Example 3 are close to the amino acid cleanser of Comparative Example 2, indicating that the mildness of the cleansing gels of Examples 1 to 6 is close to that of the amino acid cleanser.
