Description

Mud film and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a mud membrane and a preparation method thereof.

Background

According to the traditional mud film, a large amount of polymer thickener is added to realize the thickening of the mud film, the mud film is not easy to push away when being smeared due to the addition of a large amount of powder materials such as bentonite and mud, and the skin has strong tightness after being cleaned due to the absorption of a large amount of grease and water on the skin in the process of drying the mud film. In order to reduce the tight feeling, the mud film is more moist by increasing the addition amount of grease, but the mud film is not easy to clean after being dried, and more surfactants are needed to be added for easy cleaning, so that the mud film has the risk of over-cleaning, can easily damage the skin barrier, and is not suitable for being used for multiple times. The surfactant has certain irritation, so that the mildness of the mud film is influenced.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art described above. Therefore, the mud film and the preparation method thereof are provided, and the mud film has the advantages of moistening, tightness and easiness in smearing.

Irritation evaluation test

47 volunteers were searched, and the ages and sexes of the volunteers were randomly determined to meet the standards of the cosmetic hygiene code (2007 edition). The volunteers respectively use the samples prepared in examples 1-30 and comparative examples 1-17, apply 3-5g of the sample on the facial skin, wash the skin after 10-20 minutes, and observe whether there is a reaction or a delayed reaction during and 30 minutes after the application. Each volunteer was tried 3 times in a week. Whether the sample causes the irritant reaction and the reaction degree is judged according to the identification standard in the table 3, statistical analysis is carried out after recording, and the detection result is shown in the table 4.

TABLE 3 identification standards

Table 4 evaluation test results of skin irritation

As can be seen from Table 4, the results of the skin irritation evaluation tests of the mud films prepared in examples 1-19 of the present invention are negative, which indicates that the mud films of the present invention are mild, non-irritating and have practical application value. Examples 23-26 all scored 1, had a slight tingling sensation and were suspicious, with examples 24-26 having no soothing or anti-sensitivity ingredients added, respectively, and example 23 was due to surfactant replacement. Therefore, the mud film of the present invention, preferably, may be supplemented with certain soothing and anti-allergic ingredients as necessary. The preferred amino acid surfactant is sodium stearoyl glutamate.

The use feedback of the volunteers using up examples 20-30 and comparative examples 1-17 was collected, and the 28 volunteers were arranged to re-use the samples prepared in the examples for the discriminatory comparison in examples 20-30 and comparative examples 1-17, respectively, such as the volunteer using up example 20, the sample prepared in example 7 and the use feedback were re-used correspondingly, and the use feedback was collected, the volunteer using up comparative example 1, the sample prepared in example 1 and the use feedback were re-used. 28 volunteers were ranked in order, i.e., 1-11 volunteers corresponding to samples prepared using the examples for comparison in examples 20-30, respectively, and 12-28 volunteers corresponding to samples prepared using the examples for comparison in comparative examples 1-17, respectively.

The major dimensions of collecting feedback include: spreadability, moisturization, comfort, cleaning effectiveness, and overall satisfaction. Wherein, in a scoring mode, 1-10 points, the higher the score is, the more the sample is loved by the volunteer, and the better the performance is: such as easy smearing, good moisture retention and moistening, easy cleaning and strong cleaning force; overall satisfaction was the average score of the scores of the other dimensions as shown in table 5.

TABLE 5 sensory evaluation test results

As can be seen from Table 5, the comparative results were analyzed: volunteers # 1-2 felt that the differences between examples 20, 21 and example 7 were not very significant because small changes in ARLACEL 165 or Edenor C18-65 MY did not affect much the mud film of the present invention. The 3-4 volunteers felt that example 22 and 23 had inferior cleaning effect compared to example 8 because no sodium stearoyl glutamate was added to example 22, while the cleaning power and comfort were reduced by replacing example 23 with sodium lauroyl sarcosinate, so the preferred amino acid surfactant of the present invention was sodium stearoyl glutamate. The 5-8 volunteers compared with examples 24-27, 9 or 11 showed slightly poor overall satisfaction with examples 24-27, but were not very obvious because the soothing components, anti-allergy agents, and skin conditioning agents did not have much effect on the skin feel and cleansing aspects of the inventive mud film, and the comfort level was slightly poor, so the mud film of the present invention was added with the skin care ingredients at the corresponding levels. Example 19 and examples 28-30 were used by volunteers 9-11, where volunteers 9 felt example 28 slightly less clean because of the lack of bamboo charcoal in the samples; the volunteer No. 10 felt that the feeling of use in example 29 was slightly worse because lactobionic acid was not added to the sample, and felt that the skin was smoother and more delicate after use in example 19 because lactobionic acid had some exfoliating effect; volunteers 11 felt that example 30 had slightly less oil control because no witch hazel water was added.

The volunteers of Nos. 12 to 15 used comparative examples 1 to 4 and example 1, and the reduction of hectorite, magnesium aluminum silicate and sea sludge in comparative examples 2 to 4 also had a great effect on the mud film of the present invention because 10% of kaolin was reduced in comparative example 1 and the balance was supplemented with water, so that the feeling of use of the mud film was greatly impaired. The volunteers No. 16-17 felt that the samples of comparative examples 5-6 were easily cracked due to the influence of the change in the total content of the polyhydric alcohol in the mud film of the present invention on the formulation, because the moisturizing effect of glycerin was the best, butylene glycol was relatively refreshing, and the skin feel difference was the greatest when replaced with water; the experience of No. 27-28 volunteers is also poor because the total content of glycerol or polyalcohol in the sample is too high, so that the sample is greasy and is not easy to clean; therefore, the total content of the polyol and the ratio of glycerin to water in the present invention have a great influence on the sludge film produced in the present invention. The overall rating of 18-25 volunteers on comparative examples 7-14 did not exceed 7 points, only 26 volunteers on comparative example 15 scored 7.8, since there was minimal change in comparative example 15, only about 3% of the sea silt increased and the corresponding kaolin content was reduced; in the comparative example 7, the content of kaolin is increased to 30%, and the contents of the mud matrixes related to the invention are adjusted within a certain range in the comparative examples 8 to 15, but the scores of volunteers are lower, so that the contents and proportions of kaolin, hectorite, magnesium aluminum silicate and sea sludge are optimized in the invention.

Oil control effect test

According to T/ZHCA 002-2018, namely a cosmetic oil control effect testing method, the skin fat amount on the surface of the skin is measured by measuring the transparency of the oil absorption adhesive tape after absorbing sebum.

Before testing, the testee cleans the tested part with an alkaline soap-based cleaning product, and the tested part is washed clean with clear water and then is sucked dry with absorbent paper. Within 3min, the skin surface sebum amount of the sample application region and the control region were measured, respectively, 3 times at different positions in each region, and the measurement results were expressed as an average value of 3 measurements as an initial value. And measuring 3 times at different positions in the sample smearing area and the control area within the set measuring time respectively to obtain the skin surface sebum amount of each area, wherein the measuring result is represented by the average value of 3 times of measurement. Calculating the difference between the initial value and the measured value of the sample smearing area and the control area, and statistically analyzing the difference between the sample smearing area and the control area at different measuring time points. And if the difference is obvious, the sample has the oil control effect.

30 volunteers were divided into 6 groups. Each group tested the mud film samples prepared in examples 5, 6, 19, 28, and 30, respectively. The statistical test results show that the oil control effect is significantly 2 points, the effective effect is 1 point, the oil control effect is not 0 point, and the score is shown in table 6.

TABLE 6 oil control scoring results

As can be seen from Table 6: compared with examples 28 and 30, the mud films prepared in examples 5, 6 and 19 have obviously better oil control effect. Examples 28 and 30 had a certain oil control effect, probably because the formula contained kaolin, hectorite, etc., which had a certain adsorption capacity, and because example 28 did not contain bamboo charcoal and example 30 did not contain hamamelis water, the oil control effect was reduced. Comparing examples 5, 6 and 19 with each other, it can be seen that the oil control effect of example 5 is slightly inferior to that of examples 6 and 19, because 2% of hamamelis water is added in example 5, and the amount of the hamamelis water added in example 6 reaches 12%, the oil control effect is more obvious.

Cleaning effect test

30 volunteers were selected and used the mud films prepared in examples 1 to 19 and examples 22, 28 and 29 and comparative examples 1 to 4, 7, 10, 12 and 15, respectively (3 times per week, washing after 15 to 20min each application), and then the cleansing rate was counted after one week (the cleansing rate was calculated by the following method, oil absorption area was obtained by absorbing oil on the face with an oil absorbing paper, then the oil absorption area 1 was counted at 6 pm before the mask was used, then the oil absorption area 2 was counted at 6 pm after the mask was used for 3 months, the cleansing rate = (oil absorption area 1-oil absorption area 2)/oil absorption area 1 × 100%, and finally the mean cleansing rate was calculated for 3 times), and the statistical results are shown in table 7.

TABLE 7 cleaning test results

As can be seen from Table 7: the average cleaning rate of examples 1 to 19 reached more than 87%, whereas the cleaning rate of comparative examples 1 to 4 was reduced due to the reduced addition of kaolin, hectorite, magnesium aluminum silicate, and no sea sludge; in comparative examples 7, 10, 12, and 15, although kaolin, hectorite, magnesium aluminum silicate, and sea sludge were added in high amounts, the final cleaning rate was not so high because the ratio of "mud matrix content" to "water matrix content" of the mud film of the present invention was destroyed. Example 22 contained no sodium stearoyl glutamate, resulting in a reduced cleaning rate; example 28 does not contain bamboo charcoal, resulting in a reduced cleaning rate; example 29 contains no lactobionic acid and has a low effect on the stratum corneum of the skin, thus affecting the final cleaning effect.

Acne treatment efficacy test

As can be seen from the above experiments, quaternary ammonium salt-73 has no influence on the sensory evaluation of the mud film of the present invention, and because quaternary ammonium salt-73 has the acne removing effect, the acne removing test was performed on example 1 and examples 5, 6, 15 and 16 without adding quaternary ammonium salt-73.

The test method comprises the following steps: 20 volunteers (with pox on the left and right) were divided into 4 groups of 5 persons, each with the sample prepared in example 1 on the left face and the samples prepared in examples 5, 6, 15, 16 on the right face. The acne removing condition is observed after 1-2 times of use, and if the acne removing condition is effective after 1 time of use, the acne removing condition is not used for the 2 nd time. The number of effective acne-removing people was counted, and the results are shown in table 8.

Table 8 acne removal test results

As can be seen from table 8, in example 1, due to the addition of quaternary ammonium salt-73, all the volunteers with acne can achieve the acne removing effect after 1-2 times of use, while examples 5 and 15 do not exist, and in example 6, 3 volunteers also achieve the acne removing effect, possibly because 12% of witch hazel water is contained in example 16, the oil control effect is certain, and the acne removing effect can also be facilitated, and in example 16, because the content of dipotassium glycyrrhizinate is slightly higher, the dipotassium glycyrrhizinate has certain anti-allergy and anti-inflammatory effects, so that part of people can achieve the acne removing effect, but the effect difference is still obvious overall, namely, the quaternary ammonium salt-73 is added to the mud film disclosed by the invention, so that the mud film disclosed by the invention has the acne removing effect, and the quaternary ammonium salt-73 has certain application value.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous modifications and substitutions without departing from the spirit of the present invention and within the scope of the appended claims.
