Zeolite is a porous natural novel material which is formed by silicon dioxide (third major trace element in human body) and aluminum oxide tetrahedron and is formed by volcanic lava erupting in nature, flowing into specific lake water or sea water and being deposited in billions of years and crust change. Because of its unique physical structure, it is unique in that its cellular microporous cell structure makes it one of the few negatively charged minerals in nature, in these negatively charged cellular "cages" also just because of the negative charge carried by zeolite, it has the function of attracting positively charged contaminants for exchange in its body, and the microporous structure in zeolite can be subjected to moisture separation and heat exchange by adsorption and adsorption desorption principles. When moisture in the air enters the microporous structure of the zeolite, the moisture is adsorbed due to good adsorptivity of the microporous structure, forming liquid water into the zeolite. Along with the rising of temperature, the moisture evaporates gradually, and at this moment heat is conducted out from zeolite to produce the effect that generates heat, this exothermic effect is more comfortable and the mildness is high, and zeolite still can suitably increase the makeup removing cream paste and push away and scribble the sense, and is more comfortable during the use, and then makes the makeup removing experience feel better.

Test example 1

Cleansing power test for make-up (foundation solution, waterproof lip gloss, and mascara):

the 90 volunteers were divided into 9 groups of 10 persons each, and the 9 groups of volunteers were respectively using the cleansing cream prepared in examples 1 to 6 and comparative examples 1 to 3, by the following method: all volunteers uniformly clean the left forearm and the right forearm on the curved side, after the water is gently sucked by using a paper towel, 3 areas with the area of 4cm x 4cm are marked as test areas, each area is at least 2cm apart, and the 3 test areas are respectively numbered as L1, L2, L3, R1, R2 and R3. After sitting still for 20min, image acquisition was performed on each test area using a microscope, and the initial L, a, b values of the skin were measured by a spectrocolorimeter.

Then, the microscope is used for image acquisition of each test area, and the spectroscopic colorimeter is used for measuring the L, a and b values of the skin after BB cream/lipstick are smeared.

The L1, L2, L3 and R1, R2, R3 areas were cleaned by dosing (1 mL) the cleaning products prepared using the examples (the cleansing gel and the cleansing cream were used in combination after 1:1 simultaneous extrusion) or the comparative examples. Then the water is washed clean, and the water is gently sucked by a paper towel. And sitting still for 30min, and carrying out image acquisition on each test area by using a microscope, wherein the spectrocolorimeter is used for measuring the L, a and b values of the skin after makeup removal and cleaning. L represents black whiteness, with higher values of L being biased towards white for skin and vice versa; a represents the redness and greenness, the greater the value of a, the more the skin is biased to red, and vice versa; b represents the degree of blue-yellow, a larger value of b represents a more yellow-like skin, and vice versa. The laboratory keeps constant temperature and humidity, the testing temperature is 23-24 ℃, and the relative humidity is 50-60%.

The cleaning force calculation method comprises the following steps: calculating skin color difference after BB cream/lipstick is smeared compared with the initial state, and marking as delta E (after smearing); the skin color difference after makeup removal and cleansing is denoted as Δe (after cleansing) compared to the initial state. The delta E can comprehensively reflect the three-dimensional change of the skin chromaticity, the larger the delta E value is, the more obvious the change of the skin color is, the smaller the delta E value is, the closer the skin color is, the cleaning force is calculated through the delta E, and the calculation formula is as follows:

△E＝SQRT(△L* ² +△a* ² +△b* ² )

cleaning force = (Δe (post-application) - Δe (post-cleaning)/Δe (post-application)) ×100%

The results are shown in table 1 (foundation lotion), table 2 (mascara) and table 3 (waterproof lip gloss):

TABLE 3 Table 3

From the data in tables 1,2 and 3, it can be seen that: the cleansing cream has very good cleansing capacity, and the cleansing capacity is influenced by the selection of the components of grease and emulsifying agent, and as can be seen from examples 1 and 2-4, the thickening of the oil phase can be increased by zeolite, the cleansing cream is difficult to dig and the spreading property of the cleansing cream is poor along with the increment of zeolite, so that the cleansing capacity of the cleansing cream is influenced; from examples 1, 5 and 6, the cleansing effect of the individual use of the sorbitol polyether-30 tetraoleate and the laureth-3 is inferior to that of the combination use of the sorbitol polyether-30 and the laureth-3, because the sorbitol polyether-30 tetraoleate is a macromolecular emulsifier, and the laureth-3 is a micromolecular emulsifier relative to the sorbitol polyether-30 tetraoleate, the combination use can enable the micromolecular emulsifier to fill the gaps of the macromolecular emulsifier, so that the micelle is more compact, and the integral emulsifying capacity is increased.

Test example 2

Sensory evaluation test

90 female volunteers aged between 30 and 35 years were selected as subjects, and randomized into 9 groups of 10 persons each. The testing method comprises the following steps: the products of examples 1 to 6 and comparative examples 1 to 3 were used by the subjects, respectively, 1 time per night and 15 days after the use, and the time required for heat generation, the amount of heat generation and the feeling of use of the makeup remover of examples 1 to 6 and comparative examples 1 to 3 were evaluated by the subjects after the use. Wherein, the time required for generating heat is the shortest time required for generating heat sensation, and the grade is divided into none, slower, normal, faster or very fast; the heat generation level is none, less, proper or excessive; the use experience is the score of the volunteer's overall satisfaction with the cleansing cream, which is divided into 5 points, 1 being the worst, 2 being the worse, 3 being the general, 4 being better, 5 being very good. The above data were counted and the average value was calculated, and the results are shown in table 3.

TABLE 3 Table 3

Group of	Time required for heat generation	Heat generation amount	Use feeling
				Example 1	Normal state	Proper amount of	5
Example 2	Normal state	Stronger (stronger)	4
				Example 3	Quick-acting toy	Strong strength	3
Example 4	Quick-acting toy	Too strong	2
				Examples5	Normal state	Stronger (stronger)	3
Example 6	Normal state	Stronger (stronger)	3
				Comparative example 1	Slower	Less quantity	3
Comparative example 2	Slower	Less quantity	3
				Comparative example 3	Without any means for	No heat sensation	1

From Table 3, the following can be seen:

(1) The time and the heat generation amount of the makeup remover are related to the addition or non-addition of the heat sensitive agent and the use amount of the heat sensitive agent, and when the heat sensitive agent in the example 1 is zeolite, the heat generation effect is moderate and the heat sensitive effect is mild compared with the heat sensitive agent in the example 1 and the comparative example 3; in examples 3 to 5, the heat sensation effect of the product is weak or strong because the zeolite proportion is too high or too low; in comparative example 3, no heat sensitive agent was added, so the cleansing cream did not have a heat generating effect;

(2) The use feeling of the product is related to various factors such as whether the heat sensitive agent is added, the type of the heat sensitive agent, the addition amount of the heat sensitive agent, the type and proportion of grease, the type and proportion of the emulsifying agent and the like, and the use feeling of the cleansing cream prepared in the embodiment 1 is more than 4 minutes, so that the effect of the product is better, and the cleansing cream is favored by users; compared with the traditional Chinese medicine, in the embodiment 5 and the embodiment 6, when the emulsifier is only one of the sorbitol polyether-30 tetraoleate and the laureth-3, the product is sticky, the emulsifying speed is low, the product is greasy after emulsification, and the comprehensive use experience is poor, because the molecular weight of the sorbitol polyether-30 tetraoleate is large, the skin feel of the cleansing cream becomes heavy when the adding amount is large, and the molecular weight of the laureth-3 is smaller than that of the sorbitol polyether-30 tetraoleate, but the self-emulsifying effect is poor, so that the overall experience is poor; as the amount of zeolite used in examples 2-4 increased from 30% to 50%, the difficulty in digging out the paste also increased; when the oil in the comparative examples 1 or 2 is only any one of ethylhexyl palmitate or caprylic/capric triglyceride oil, the product has poor use effect and thick skin feel when being smeared; in comparative example 3, no heat sensitive agent was added, the product did not generate heat, the absorption effect was poor, and the support of zeolite was not provided, and the wax-based unit was unstable.

Test example 3

Stability evaluation:

stability testing includes high temperature, low temperature, and cold and hot cycle testing. Namely, the makeup remover provided in examples 1 to 6 and comparative examples 1 to 3 were left at 45℃and 15℃for 3 months, respectively, and the appearance of the product was regularly observed for appearance abnormalities such as cloudiness and delamination, and after 3 cycles of cold and hot cycles at-18℃and 25℃the appearance of the product was observed for appearance abnormalities. The test results are shown in Table 4.

TABLE 4 Table 4

As can be seen from Table 4, the cleansing cream system of the present application has better stability and excellent high and low temperature stability, and the zeolite can increase the consistency of the oil phase and the stability of the cream to some extent.

Test example 4

Safety evaluation:

the specific method comprises the following steps: 40 women aged 18-35 years were selected, each subject was tested with the cleansing cream prepared in examples 1-6 and comparative examples 1-3, without allergy history. After cleaning the back of the subject, the plaque test with the sample is applied to the selected position of the back by using a non-irritating adhesive tape, and the plaque test is uniformly applied to the skin by slightly pressing the back with fingers after the plaque test is applied, and the time lasts for 48 hours. The spot paste part is kept dry in the 48h of the subject, so that the intense exercise, the scratching of the spot test part, the long-time sunlight irradiation and the like are avoided. After 48 hours, the tester is removed and marked, and after 30 minutes, the judgment is carried out under sufficient light after the isobaric mark disappears.

The skin adverse reaction grading criteria are shown in Table 5:

TABLE 5

The results are shown in Table 6:

TABLE 6

As can be seen from the data in table 6: except for examples 3 and 4, the subjects in each group had negative reactions, which indicated that the corresponding cleansing cream had no adverse reaction to the human body, and was high in safety, and when the amount of zeolite in examples 3 and 4 was too large, the amount of heat generated was large, discomfort was likely to occur, and as the amount of zeolite was increased, the thickness of the paste was also increased, and the overall smoldering sensation was increased.
