Since common cationic emulsifiers are highly irritating, their use in skin care product formulas is very limited. However, in addition to emulsification, cationic emulsifiers also have many excellent characteristics. For example, cationic emulsifiers usually have the functional characteristics of waterproofing, anti-sand, long-term moisturizing, and soft, silky skin feel. How to overcome the shortcomings of cationic emulsifiers and give full play to their performance characteristics and apply them in skin care products is of great significance.

[0053] Testing: Patch tests were performed on Examples 1-3 and Comparative Examples 1-8. The testing method is as follows: a qualified patch tester was selected, and 0.02-0.025 g of the samples of Examples 1-3 and Comparative Examples 1-8 were applied to the patch tester using a closed patch test method. The test substances were removed after 24 hours, and the skin reactions were observed at 0.5, 24, and 48 hours after removal. The results were recorded according to the skin reaction grading standard in the "Technical Specification for Safety of Cosmetics" (2015 edition). The test results are shown in Table 1;

[0054] The stability test of Examples 1-3 and Comparative Examples 1-8 was performed as follows: the samples of Examples 1-3 and Comparative Examples 1-8 were placed at room temperature for 3 months, 50°C for 3 months, and -16°C for 3 months, and a high and low temperature cycle test was performed, in which the samples were placed in 50°C and -16°C environments, and each temperature was placed for one month and then cycled for 3 times;

[0055] The skin feel test was conducted on Examples 1-3 and Comparative Examples 1-8. The test method was as follows: 20 test subjects with healthy facial skin were selected, and the 20 test subjects tried the skin care creams of Examples 1-3 and Comparative Examples 1-8 one by one. Before the trial, the test subjects all went through the same skin care procedure. After the trial, the test subjects evaluated the use. The evaluation index included the use feeling (refreshing, greasy, soft). The test results are shown in Table 1;

[0056] Table 1.

[0057]

[0058]

[0059] The products of Example 1 and Comparative Example 1 were tested for their sand resistance. The test method was as follows: 0.3 g of the samples of Example 1 and Comparative Example 1 were evenly applied to the designated areas of the left and right forearms of the test subject. After 1 minute, 30 g of fine sand was sprinkled on the left and right forearms, and the test subjects clapped their hands three times. The sand residue on the left and right arms was recorded. The results are shown in Table 1. Figure 1 ;

[0060] The moisturizing performance of the products of Example 1 and Comparative Example 1 was tested. The testing method is as follows: Referring to the method of QB / T 4256-2011 "Guidelines for the Evaluation of Moisturizing Efficacy of Cosmetics", the moisturizing performance of the products of Example 1 and Comparative Example 1 was tested respectively. The subjects were followed up for 12 hours using a skin keratin moisture tester. The results are shown in Table 1. Figure 2 ;

[0061] Through the above tests, it can be seen that the samples prepared by Examples 1-3 of the present invention are safe and stable products, with a refreshing and soft skin feel, and have the characteristics of anti-sand and long-lasting moisturizing. However, in the sample of Comparative Example 1, no cationic emulsifier was used. When the same amount of oil was emulsified, although the product was safe and stable, the skin felt greasy; the samples of Comparative Examples 2, 3, 4, 6, and 7 verified the irreplaceability of each composition of the cationic emulsifier. Case 2 and Case 4 did not add the auxiliary emulsifiers glyceryl stearate and cetearyl alcohol, respectively. The results showed that the stability of the products could not pass the test; Comparative Example 3 increased the amount of distearyl dimethyl ammonium chloride on the basis of Comparative Example 2, and the product safety was not up to standard; Comparative Examples 6 and 7 used hydroxyethyl cellulose and xanthan gum to replace deacetylated chitosan, respectively, and the problems of greasy skin feel and unsatisfactory stability appeared respectively; Comparative Examples 5 and 8 reduced and increased the amount of deacetylated chitosan, respectively, but also had the problems of poor stability and sticky skin feel, respectively.
