Traditional soap-based cleansing has strong degreasing capability, has great negative influence on acid-base environment and microecology of skin, and can cause certain irritation.
Amino acid cleansing is weakly acidic or neutral, mild and non-irritating, and has become the mainstream of the market, but the current amino acid cleansing still generally has some problems, such as weak cleaning ability.

It can be seen from Table 2 that there is a significant improvement in sebum secretion after cleansing using the facial cleanser products of the present application, and still a lower amount of sebum after 8 hours.
(4) Moisturizing effect
5 volunteers were randomly assigned to each facial cleanser product and tested for skin moisture over time after facial cleansingAnd calculating the difference before face cleaning, namely, the percutaneous moisture loss TEWL (g/m) 2 h) The calculated average is shown in table 3, and the larger the data, the more moisture the skin holds relative to the initial state, and the better the moisturizing performance. The test instrument was a CK Vapometer and the test area was the cheek.
TABLE 3 Table 3
It can be seen from table 3 that the facial cleanser product of the present application can achieve moisturizing effect for up to 8 hours.
From the test results, the amino acid cleaning product obtained by the application has the advantages of fine and rich foam, mildness, no stimulation, simple components and good oil control and moisture retention.
The preferred embodiments of the present application have been described in detail above, but the present application is not limited thereto. Within the scope of the technical idea of the application, a number of simple variants of the technical solution of the application are possible, including combinations of the individual technical features in any other suitable way, which simple variants and combinations should likewise be regarded as being disclosed by the application, all falling within the scope of protection of the application.
