the soap pellets prepared in examples 1-5 were subjected to the oxidation stability test, and the test methods and test results are shown below:
the test method comprises the following steps: the cured soap pellets obtained in examples 1 to 5 were divided into three equal portions, which were placed in paper boxes, the first portion was placed in an oven environment at a constant temperature of 45 ℃, the second portion was placed in an ambient temperature environment, and the third portion was placed in a refrigerator at 4 ℃ (the third portion was used as a standard sample for subsequent observation of color changes).
The color change of the sample is observed once a week in the early month, compared with the standard sample, and the smell is smelled. After one month, the observation was carried out for two weeks, and the color change and the odor change were observed in comparison with the standard sample until the end of the 100 th day.

The eco-friendly soaps prepared in examples 1 to 5 and comparative examples 1 to 3 were subjected to measurements of foamability, wet crack property, wet soap touch and water wettability of skin surface, and the test methods and test results are as follows:
the test method comprises the following steps:
(1) foaming test: the measurement was carried out according to the method for measuring the foaming power of GB7462, and the results are expressed in terms of the number of milliliters of foam formed when the flow of liquid was stopped for 5 min. (2) And (3) wet cracking property test: completely soaking the environment-friendly soap in water with the constant temperature of 30 ℃ for 2h, then draining, drying at the temperature of 30 ℃ for 16-24h, observing the crack condition of the environment-friendly soap, and grading, wherein 0 represents that the soap body has no crack, 5 represents that the crack of the soap body is serious, and the grade of 0-5 reflects the crack occurrence condition of the environment-friendly soap;
(3) wet soap gritty feel test: placing the environment-friendly soap in tap water at 26.7 +/-1 ℃, slightly rubbing the environment-friendly soap with a palm for about 1min, judging the smoothness and the roughness (whether obvious sandy sense exists) of the surface of the environment-friendly soap by touch, grading, wherein 0 represents that the soap body is smooth and has no sandy sense, 1-3 represents that the soap body has slight sandy sense, more than 4 represents that the soap body has more sandy sense and the hand feeling is rough, and the grade of 0-5 reflects the wet soap touch grade of the environment-friendly soap;

then, the cleansing was performed using the eco-friendly soaps of examples 1 to 5 and comparative examples 1 to 3, respectively, and the water and oil values of the skin 10min after cleansing were tested.
And (3) testing results:
according to the comparative analysis of the data, the surfactant in the environment-friendly soap in the comparative example 1 is only sodium dodecyl sulfate, so that the environment-friendly soap is low in foam height and poor in foamability, and the environment-friendly soap disclosed by the invention is prepared by compounding the sodium dodecyl sulfate and the coconut oil acid hydroxyethyl sodium sulfonate, so that the foaming power and the foam stability of the environment-friendly soap can be effectively improved, the foam is rich and fine, and the dirt-removing capacity of the environment-friendly soap can be promoted.

Comparative example 3 no moisturizing factor was used in the environment-friendly soap, the moisture value of the skin surface cleaned with the environment-friendly soap did not increase much, and the oil value was higher than that of other examples, which shows that by using the moisturizing factor of the present invention, moisture can be supplemented in time while the skin is fully cleaned with the environment-friendly soap, the phenomenon of water-deficient dry wrinkles after full cleaning (the phenomenon of slightly higher oil value due to the fact that skin is in water-deficient dry wrinkles and can automatically secrete oil to protect epidermal cells) is avoided, and the cleaning and moisturizing effects of the environment-friendly soap are improved.
