For the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1 to 7, the appearance of the samples was observed, wherein the samples in example 3 and comparative examples 3 to 6 exhibited smoother texture, the samples in comparative example 1 had more bubbles, and the surfaces were not easily leveled after filling. Comparative example 2 was stratified, and it was confirmed that the raw material 8 (polyacrylate-13, polyisobutylene, and polysorbate-20) alone, which has thickening properties, did not provide sufficient suspending power to the pearl powder at the addition amounts shown in table 1. Comparative example 4 compared to comparative example 3, after the addition of polyacrylate-13, polyisobutylene and polysorbate-20, the product had increased viscosity, a smooth appearance, and a slightly reduced flowability during filling, but was still easier to fill. Compared with the comparative example 1, after the polyacrylate-13, the polyisobutylene and the polysorbate-20 are added, the phenomenon that the bubbles in the material body are more is reduced, the viscosity of the material body is increased, the overall fluidity is stronger, and the filling is easier, because the surface tension of the material body is reduced due to the addition of the polyacrylate-13, the polyisobutylene and the polysorbate-20, a certain defoaming effect is achieved. Through comparative analysis, after primary appearance observation, the examples 3 and the comparative examples 3 to 6 have better appearance and are suitable for product production. Comparative example 7 compared with example 3, the body contained agglomerates, had an uneven surface, high fluidity, easy filling, but a rough appearance.

Experiment 1 viscosity test

The aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1 to 7 were measured by NDJ-8S digital viscometer of Shanghai Square instrument, Inc., and the results are shown in Table 2.

TABLE 2

As can be seen from Table 2, the viscosity of comparative example 2 is approximately 0, and comparing comparative example 4 with comparative example 3, comparative example 6 with comparative example 5, and example 3 with comparative example 1, it can be seen that the viscosity of the product can be increased by adding polyacrylate-13, polyisobutylene, and polysorbate-20, mainly due to the fact that polyisobutylene is contained in polyacrylate-13, polyisobutylene, and polysorbate-20, and the acrylate polymer, wherein polyisobutylene has a large resistance to free molecular movement due to its high molecular weight, which increases the viscosity of the product, and the acrylate polymer increases the viscosity of the solution through chain entanglement thickening. Dissolved in water, the viscosity of example 3, comparative example 1, comparative example 7 was relatively low. The viscosity can reflect the texture of the product when the product is smeared on the surface of the skin to a certain extent, and if the viscosity is too high, the product is sticky in the smearing process. From the viscosity results, example 3, comparative example 1, and comparative example 7 should have a lighter, thinner, moist skin feel.

Experiment 2 product stability test

This experiment performed stability tests on the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1 to 7, and the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1 to 7 were respectively placed in a transparent plastic bottle and placed in an oven at 45 ℃ for 1 week to observe the conditions of the samples. As can be seen from fig. 1, the addition of different thickeners has a greater effect on the stability of the product, wherein example 3, comparative example 1, comparative example 3, comparative example 4, comparative example 7 have better stability, but the possibility of delamination is greater over time due to the agglomerates contained in comparative example 7, while comparative examples 2, 5, 6 all show delamination after 1 week of standing, wherein comparative example 2 delaminates after preparation. Comparative examples 5 and 6 were delaminated after being left for 1 week, and comparative example 5 was more remarkably delaminated since polyacrylate-13, polyisobutylene and polysorbate-20 were not added, whereby it was found that the thickening efficiency of hydroxyethylcellulose was inferior to that of xanthan gum and carbomer, and the addition of small amounts of polyacrylate-13, polyisobutylene and polysorbate-20 could improve the suspending ability of the product for pearl powder to some extent.

Combining the viscosity test result of experiment 1, the addition of polyacrylate-13, polyisobutylene and polysorbate-20 can increase the viscosity of the product, and the increase of the viscosity can prevent the free movement of the pearl particles to a certain extent, so as to reduce the sedimentation between the particles. As can be seen from the stability results, example 3, comparative example 1, comparative example 3, and comparative example 4 have relatively good stability and commercial conversion value.

Experiment 3 Water resistance test

The aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1 to 7 were respectively applied to the surface of the covering power test card paper with a brush and naturally washed with water to conduct a waterproof performance test. The application before rinsing is shown in figure 2 and after rinsing is shown in figure 3. As can be seen from fig. 2 and 3, the waterproof performance of comparative examples 3 and 4 is poor under the condition of using the same film forming agent, and is not substantially retained after being washed with water, because the main thickener in comparative examples 3 and 4 is xanthan gum, which is presumed to have an effect on the film forming of the styrene/acrylate copolymer due to the cation in the molecule, thereby affecting the waterproof performance of the product. And in example 3, comparative examples 1,2, 5, 6 and 7, the waterproof effect is very good, and the waterproof paint still retains a good form after being washed by water, and has a good commercial application value.

Example 3 is most commercially worthy of popularization, combining product appearance, flow, tack, stability and water resistance tests. The skin of the embodiment 3 has a relatively moist skin feel, and is not easy to agglomerate when being smeared on the surface of the skin; the product has good self-leveling property, is convenient to fill, and has certain effect of reducing surface tension after polyacrylate-13, polyisobutylene and polysorbate-20 are added, so that a large amount of bubbles are not generated after filling in example 3. Compared with comparative examples 3-6, the carbomer is selected as the thickening agent in example 3, and the stable thickening and suspending effects can be achieved by using a smaller adding amount. It performed better in the high temperature stability test than hydroxyethyl cellulose thickener. The main reason is that the carbomer can better realize the joint thickening of a continuous winding thickening mechanism and an association thickening mechanism under the system condition, and through the extension of a branched chain, hydrogen bonds are formed with water molecules in a solution, so that the free movement of pearlescent particles is reduced, and the sedimentation effect is inhibited. In addition, the example 3 has better waterproof performance, and when the polyurethane 35 and the styrene/acrylate copolymer compound film forming agent are used, compared with xanthan gum which is a thickening system, the structure of carbomer and the film forming agent are better compatible without influencing the film forming capability, so that the aqueous liquid eye shadow prepared in the example 3 has the best effect.

Experiment 4 human skin feel test

The evaluation method comprises the following steps:

50 trial volunteers of products are recruited, the age interval is 20-40, five dimensions of the aqueous liquid eye shadow samples prepared in the example 3 and the comparative examples 1-7 are respectively used and tested, the samples are randomly divided into 5 groups, 10 volunteers in each group, one dimension of the aqueous liquid eye shadow samples prepared in the example 3 and the comparative examples 1-7 is tested and scored, the scoring range is 0-5, and finally, the average score of each dimension is counted. Since volunteers do not have a uniform concept of how bad the sample is in one dimension, the scoring results are only relative scores generated for the comparisons between the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1-7, and are not absolutely bad.

Grade scoring criteria:

0 minute: a difference; 1 minute: slightly worse; and 2, dividing: common; and 3, dividing: slightly better; and 4, dividing: the method is good; and 5, dividing: very good.

Evaluation method 1: in the viscometric test before use, 10 volunteers selected a uniform rubber-tipped dropper to suck 0.1ml of sample to the center of the back of the left hand, and took a food to dip the sample three times with the right hand, and after the test, the viscosity degree of the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1-7 was subjectively scored.

Evaluation method 2: and (3) viscosity test of the samples after use, wherein 10 volunteers dip 0.1g of the samples into the inner side of the left arm 2cm away from the wrist by using a uniform liquid eye shadow brush, and smear the samples up and down by using the eye shadow brush for three times, wait for five minutes, smear the test samples up and down by using the index finger of the right hand for three times, and subjectively score the viscosity degree of the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1-7 after the test is finished.

Evaluation method 3: sample cosmetic retention test, 10 volunteers dip 0.05g of sample by using a uniform liquid eye shadow brush head, uniformly coat the sample on an upper eyelid, try the sample once a day with 8 hours of makeup each time, and subjectively score the cosmetic retention of the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1-7 after two weeks.

Evaluation method 4: and (3) sample smearing test, wherein 10 volunteers select a uniform rubber dropper to suck 0.1ml of sample to drip in the center of the back of the left hand, smear the sample in a mode of drawing circles clockwise by the index finger of the right hand, feel whether the sample is easy to smear, and after the test is finished, subjectively score the viscosity degree of the aqueous liquid eye shadow samples prepared in the example 3 and the comparative examples 1-7.

Evaluation method 5: the sample skin adhesion test, wherein 0.05g of sample is dipped by a uniform liquid eye shadow brush head and uniformly coated on an upper eyelid of 10 volunteers, the eyes are moved after film formation to realize the adhesion degree of the sample on the skin, after the test is finished, subjective scoring is carried out on the viscosity degrees of the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1-7, and the results are shown in table 3.

Table 3: average score of indexes of example 3 and comparative examples 1 to 7

Example 3 had a light, thin, moist skin feel with a weak sticky feel before and after use. The coating property in the makeup process is good, and the skin-sticking property after film forming is excellent. There was almost no makeup removal during the 8 hour test.

Comparative example 1 had a weak sticky feel before and after use, and more had a light, thin and moist skin feel. The coating property in the process of applying to eyes is good, and the skin sticking property after film forming is obvious. Almost no makeup removal occurs after 8 hours of makeup testing. However, as is clear from the results of the above experiment 1, the surface of the material body of comparative example 1 was not easily leveled after filling, since many bubbles were present in the material body.

Comparative example 2 had almost no sticky feeling, and was poor in spreadability and skin-sticking property, and the pearlescent toner was not uniformly distributed with the flow of water. When the eye shadow is made up, the eye shadow is stranded by gravity, and the makeup durability is poor.

Comparative example 3 had strong stickiness before and after use, poor skin-adhesion, pearl particles overflowing after film formation, and strong discomfort after application, mainly manifested by heavy eyelid stickiness, significant skin pull when eyes are opened and closed, and poor makeup-holding property. But the spreadability on the eyes was good.

Comparative example 4 the surface was relatively flat after film formation, dry without stickiness, and no noticeable foreign body sensation on touch. The spreadability and the skin-sticking property were good when applying to the eye, but the makeup-sustaining property was poor, and makeup was almost completely removed on the eyelid after 8 hours of makeup-wearing test.

Comparative example 5 has good stickiness before and after use, the eyelids are comfortable after makeup without foreign body sensation, and almost no makeup removal phenomenon is caused after 8 hours of makeup test, but the smearing property is poor, the accumulation of pearl toner is easy to generate, and the color is not uniform during makeup.

Comparative example 6 has a heavy sticky feeling before and after use, a strong sticky feeling after makeup, and a heavy feeling. The smearing property is generally sensed in the process of putting on eyes, and the skin-sticking property is generally sensed after film forming. But no significant makeup removal was observed in the 8-hour makeup test.

Comparative example 7 had no sticky feeling before and after use and a moist skin feeling, but the film formation was too slow and it was easy to rub the mud. The formulation may have incompatibility problems and agglomerates may appear in the paste.

In summary, in the aqueous liquid eye shadow samples prepared in example 3 and comparative examples 1 to 7, example 3 is superior to comparative examples 1 to 7 in various data and indexes, which shows that the aqueous liquid eye shadow product provided by the present invention has light texture, thin and moist texture, comfortable makeup, and durable waterproof effect.
