experiment example 1
[0054] Experimental example 1 Evaluation of mite removal effect
[0055] Conducted in accordance with NY / T1151.2-2006 "Indoor efficacy test methods and evaluation of insecticides for pesticide registration and sanitation Part 2: Mites and repellents" and GB / T 24253-2009 "Evaluation of anti-mite performance of textiles" The mite removal effect test was carried out, and the results are shown in Table 2.
[0056] Table 2
[0057] sample Example 1 Example 2 Example 3 Comparative example 1 Comparative example 2 Mite repellent rate 99.75% 99.64% 99.71% 93.32% 82.21%
[0058] The results in Table 2 show that the facial cleanser of the present invention has a very significant mite removal effect. Moreover, the effect is better than that of the comparative example, indicating that the combination of the mite-removing traditional Chinese medicine composition and the acne-removing traditional Chinese medicine composition has a synergistic and synergisti...
experiment example 2
[0059]Experimental Example 2 Oil Control Efficacy Evaluation Experiment
[0060] 1. Test principle
[0061] The oil content of the skin was tested with a sebumeter SM815. It is based on the principle of photometers. After a special 0.1mm thick matting tape absorbs the oil on the human skin, it will become a translucent tape. Its light transmission will change, and the more oil it absorbs , the greater the amount of light transmitted, so that the content of skin oil can be measured.
[0062] 2. Test equipment:
[0063] SebumeterSM815 (German Courage+Khazaha company)
[0064] 3. Test samples
[0065] The facial cleanser prepared in Examples 1-3.
[0066] 4. Test method
[0067] 30 subjects with oily scalp. Subjects sat quietly in a laboratory with a temperature of 22±3°C and a relative humidity of 50±5% for 30 minutes, and tested the skin oil content of the left and right foreheads with an oil tester SebumeterSM815, recorded as the data of D0, and distributed the samples ...
experiment example 3
[0075] Experimental Example 3 Moisturizing Effect Evaluation
[0076] 1. Sample preparation and instruments
[0077] Prepare the facial cleanser samples prepared in Examples 1-3 respectively, and carry out the following experiments.
[0078] The experimental instrument is a skin moisture content Corneometer test probe manufactured by German Courage+Khazaka Company (Germany CK Company).
[0079] 2. Experimental principle
[0080] The higher the skin moisture level, the higher the skin water content, and the lower the TEWL value of skin water loss.
[0081] 3. Test method of skin moisture content
[0082] In this experiment, the water content test used the Method - capacitance method.
[0083] Select 100 people with dry skin, aged between 20 and 45, half male and half male. Before the test, the subjects were required to wash their facial skin and sit quietly for 30 minutes in a constant temperature and humidity room with a temperature of 22±1°C and a humidity of 50±5% 2 h...
