Problems solved by technology

[0004] However, mineral oil is difficult for the skin to absorb, and it is difficult for polyols to have an ideal moisturizing effect in a dry environment
Moreover, these mineral oils and high-concentration polyols are difficult to be absorbed by the skin and stay on the skin surface for a l

[0070] Example 4

[0071] Human skin moisture content test of different ages in dehumidified environment

[0072] Fifteen female test volunteers aged 20-35 were selected, 5 of them were 20-25 years old, numbered 1-5, as the first age group, 5 subjects were 25-30 years old, numbered 6-10, as the first age group Subjects in the second age group; 5 subjects aged 30-35, numbered 11-15, as subjects in the third age group. Two symmetrical areas of the face are selected as the test areas of the control group and the test group respectively, and tested in a dehumidified environment [temperature 20°C, humidity 50%], and the test item is a moisture content test. The test group used the water-locking moisturizing cream prepared in Example 1, and the control group used the ordinary moisturizing cream prepared in Comparative Example 1. The two were subjected to the same test under the same conditions. The moisture content test is within the planned time interval, and the test period is 8 hour...

Example Embodiment

[0080] Example 1 (EG) and Comparative Example 1 (CG) the test results of the increase in moisture content in Table 2 and Figure 2A-2C Shown:

[0081] Table 2 Growth rate of skin moisture content

[0082]

[0083]

[0084] Based on the above test data, the following test results are obtained:

[0085] 1. Due to the difference in skin age, overall, the older group has a more obvious drop in skin moisture content in a longer time interval, and the control group is more obvious than the test group.

[0086] 2. In all age groups, the test group still has a better moisture content in the skin over a longer time interval, while the control group is significantly lower than the test group under the same conditions.

[0087] In addition, according to the above test method, the water-locking moisturizing cream prepared in Example 2 and the ordinary moisturizing lotion prepared in Comparative Example 2 were used as tests and controls, and the water-locking moisturizing gel prepared in Example 3 ...

[0092] Example 5

[0093] Determination of the moisturizing effect of different active ingredient combinations on the skin:

[0094] Five subjects in the second age group 25-30 years old in Example 4 were selected, numbered 1-5, and five arm regions were selected as Example 1, Comparative Example 4, Comparative Example 5, Comparative Example 6, and Comparative Example 1. The test areas of scale 7 are numbered A, B, C, D, and E respectively. Test in a dehumidified environment [temperature 20°C, humidity 50%], and the test item is moisture content test. Do the same test under the same conditions. The moisture content test is within the planned time interval, and the test period is 8 hours.

[0095] The skin moisture content test method is the same as in Example 4. The test results of the moisture content growth rate are shown in Table 4 and image 3 Shown:

[0096] Table 4 Changes in the growth rate of skin moisture content using compositions containing different active ingredients ...

Abstract

The invention belongs to the field of cosmetics, and relates to a moisture locking and moisturizing composition, in particular to a three-dimensional moisture locking and moisturizing composition with the mousse texture. The composition is prepared from a polymer absorbent material for moisture releasing, a film forming polymer for moisture retention and ceramide for deep repairing and moisturizing. The composition forms a three-dimensional moisture locking and moisturizing system and can moisturize the skin for a long time; in addition, the composition has the mousse-like texture, and when the composition is used, the unique skin sensation is achieved, and the skin can be smoothened instantly.

Description

technical field [0001] The invention belongs to the field of cosmetics, and relates to a mousse-like composition, more specifically, to a composition with a three-dimensional water-locking and moisturizing system. Background technique [0002] Human skin is composed of epidermis, dermis and subcutaneous fat tissue, and each layer contains water. The skin is directly exposed to the atmospheric environment, which can expel moisture from the body to the atmosphere and absorb moisture from the outside. The water content of the outermost stratum corneum of the skin should generally not be less than 10%. The skin with a water content of 10-20% is soft, smooth and elastic. If it is less than 10%, the stratum corneum of the skin is too dry, and even scales or cracks appear. . Dry skin is prone to premature aging, and the appearance of scales or cracks in the skin will cause the skin to lose its barrier function, causing bacteria and viruses to easily enter the human body through t...
