Description

Skin cleaning composition and preparation method and application thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a skin cleaning composition as well as a preparation method and application thereof.

Background

According to the definition of "cosmetic supervision and management regulation" applied from 1/2021, cosmetics refer to daily chemical industry products applied to the surface of human body such as skin, hair, nails, lips, etc. by smearing, spraying or other similar methods for the purpose of cleaning, protecting, beautifying and decorating. The classification principle of cosmetics in China is mainly classified according to the functions and the use parts of the products. The products are classified according to their functions into cleaning cosmetics, nursing cosmetics, beautifying cosmetics and decorative cosmetics. They are classified into skin cosmetics, hair cosmetics, nail cosmetics, and lip cosmetics according to the site of use. Among them, the cleansing cosmetic is intended to remove dirt on the skin, to keep the skin fresh, and to contribute to the maintenance of the normal physiological state of the skin. The face cleaning product belongs to a major class of cosmetics and accounts for more than 10% of the cosmetic market. At present, the types of face cleaning products in domestic markets are various, the face cleaning products are increasingly paid attention by consumers and manufacturers, the requirements of people on the face cleaning products are higher and higher, and the development of the formula of the face cleaning products is more and more important.

Currently common facial cleansing products are facial cleansing cream, facial cleansing milk, facial cleansing gel (facial cleansing gel), facial cleansing bubbles (facial cleansing mousse), and the like. The cleansing cream has thicker texture, abundant foam and stronger cleaning power, has the function of makeup removal, can effectively remove isolation and sunscreen products and the like, and is suitable for the skin which is not sensitive to oiliness and mixing; the face cleanser has abundant foam, more water and milder and moist property, and generally does not stimulate the skin; the face-cleaning gel (face-cleaning gel) is more fresh and mild than face-cleaning cream and face-cleaning milk, and is suitable for sensitive and dry skin; the cleansing foam (cleansing mousse) allows abundant foam to be directly extruded from a pump port due to the progress of packaging design, has simple formula, no thickening, low surface active concentration, mildness, refreshing property and no residue, and is suitable for various skin types and seasons. With the increasingly stringent requirements of consumers on the appearance of the face cleansing product, the market demand for diversified formulations of the face cleansing product is also increasing.

The formula of the face cleaning product mainly comprises water, a surfactant, a thickening agent, a humectant, a preservative, essence and the like. Currently available facial cleansing products are roughly classified into soap-based type and amino acid type ones according to the difference in main activity. The soap-based cleansing facial mask is usually rich in foam, easy to wash, fresh and cool in skin feel and strong in cleansing force; the disadvantages are that the soap base is slightly alkaline, the degreasing force is too strong, the skin is easy to be dry and astringent after washing, the skin irritation is larger, the requirements on saponification technology such as stirring speed and temperature in the production process are higher, and the batch stability is difficult to ensure. The amino acid type cleansing is safe and mild, the cleansing power is moderate, and the skin feel is smooth; the disadvantages are that the foam is not rich enough, the consumer feels no clean after washing with false slip, the thickening is difficult, the water is easy to dissolve, and the viscosity of the material body is obviously reduced in the using process. How to match the formula of the face cleaning product ensures that the viscosity of the product is stable in the life cycle while considering rich foam, moderate cleaning power, easy washing and low irritation, and is another problem to be solved by the face cleaning product.

Effect example 5 percutaneous Water loss test

Trans Epidermal Water Loss (TEWL), also known as transdermal Water Loss, represents the degree of Water Loss from the dermis by evaporation through the epidermis, and is an important parameter describing the barrier function of the skin, which is closely related to the Water content of the stratum corneum of the skin. The lower the TEWL value, the less water is lost through the skin, the better the barrier function of the stratum corneum; conversely, the poorer the barrier function. The test was carried out on the volunteers using the product using a moisture percutaneous loss tester (Tewameter TM 3000).

Randomly selecting 90 effective volunteers, wherein 45 male and female patients are selected, the age is 18-45 years (except for pregnant and lactating women), the tested part has no skin problem in the next month, no history of system diseases and no history of severe allergy to skin care products. Before testing, volunteers were asked to wipe both arms with clear water, sit still for 30 minutes in a constant temperature and humidity environment (temperature: 25. + -. 1 ℃ C., relative humidity: 40. + -. 5%) and to remain relaxed. A4 x 4cm test area is marked on the inner side of the arm of a volunteer 5cm away from the base of the palm, a plurality of areas (interval of 1cm) can be marked on the same arm at the same time, test examples and comparative examples are randomly distributed on the left arm and the right arm, and the marked areas can not be coated with medicines or cosmetics irrelevant to the experiment during the test. The same amount (2g) of samples are respectively used in the marking areas of the volunteers for 4 continuous weeks (the testing area of each volunteer is 9, each area of each volunteer fixedly uses one sample, and each person uses the samples for 1 time every day), and the samples are rubbed for the same number of turns to be washed clean and naturally dried. Before use, at week 1,The transdermal water loss values of the test area were measured and recorded using a Tewameter TM3000 at week 2 and week 4, respectively (TEWEL-_W0、TEWEL-_W1、TEWEL-_W2、TEWEL-_W4) And the change value Δ tewell after 4 weeks of use was calculated (tewell-_W4)-(TEWEL-_W0) The test results (average of the experimental data obtained) are shown in table 12: the higher the transdermal water dispersion loss of the volunteers with the increase of the test time, which indicates that different types of facial cleansing products can damage the skin barrier; as can be seen from Delta TEWEL, the facial gels of examples 1-6 of the present invention have a weaker effect on the skin barrier than the soap-based facial cleanser of comparative example 1 and the pearlescent facial cleanser of comparative example 3, and are close to the amino acid facial cleanser of comparative example 2, indicating that the mildness of the facial gels of examples 1-6 is close to that of the amino acid facial cleanser.
