Description
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a moisturizing makeup removing composition and a preparation method and application thereof.
Background
In order to take account of both the freshness and the transparent appearance (formula stability), the selection range of the emulsifier is relatively narrow, and the makeup removing force of oily makeup (such as lipstick, eye shadow and the like) is generally weak, so that the situations of incomplete makeup removal and more residues are easy to occur. In addition, the makeup removing water system mainly comprises free water, and compared with systems such as makeup removing oil/cream and makeup removing milk, the environment with high water content is more beneficial to the growth and the propagation of microorganisms. Thus, cleansing water formulations generally require higher amounts of preservative added, but at the same time this also results in relatively higher irritation, especially eye irritation.
The moisturizers which can be added into the makeup removing water are usually polyhydric alcohols, polysaccharides, amino acids and the like, and generally have good moisture absorption capacity and good moisturizing effect in resident products. But the water-locking capacity of the components is general, and the components have strong water solubility, so that the components are easy to be washed in a large amount when being applied to rinsing products, thereby causing the limited moisturizing effect. If the moisture retention capacity of the makeup remover is insufficient, the skin is lack of water after long-term use, so that the skin is aged and lacks luster.
Therefore, the preparation of the makeup remover product which can remove the makeup comprehensively and has small skin irritation and certain moisturizing effect is of great significance.

The makeup removing composition disclosed by the invention is compounded by the sucrose laurate emulsifier and the cetostearyl alcohol polyether-20, so that the synergistic effect can be realized, and the makeup removing composition has a remarkable cleaning effect on oil-based makeup (such as lipstick, eye shadow, foundation make-up and the like) and water-based makeup. And the caprylyl hydroximic acid, the caprylyl glycol and the EDTA disodium are compounded according to a proper proportion for bacteriostasis, so that the makeup removing composition replaces the traditional preservative, has better mildness, can remove makeup comprehensively, has small irritation to skin and has a certain moisturizing effect.
The sucrose laurate emulsifier is a natural sucrose-derived nonionic emulsifier (e.g., RYOTO) TM SURAR ESTER L-1695), the hydrophilic and lipophilic ends of which have good skin-adhering properties, remain mild, safe and non-irritating to sensitive eyes; in the makeup removing process, the longer fatty chain can be better dissolved with oily substances in makeup, and the sucrose laurate has higher affinity with the skin and can be more quickly dispersed and permeated along the skin, so that the effect of high-efficiency makeup dissolving is achieved; after makeup removal and washing, a light and thin water-locking film can be formed on the surface of the skin, and the water loss in the skin is reduced. Ceteareth-20 is a non-ionic surfactant suitable for formulating oil-in-water type emulsifiers, such as
CE 200F is a mild nonionic O/W emulsifier, is completely soluble in water, has strong emulsifying power, and can enhance makeup removing effect and cleaning effect. The composition provided by the invention is prepared by compounding the sucrose laurate emulsifier and the ceteareth-20, can be used for completely removing oily color cosmetics and aqueous color cosmetics, has small skin irritation, can form a light and thin water-locking film on the surface of skin after being used, and has a certain moisturizing property.
As a preferred embodiment of the moisturizing cleansing composition, the moisturizing agent comprises 0.045-0.12% of octanediol, 0.045-0.12% of glycerin and 5-10% of 1,3-propylene glycol by weight of the moisturizing cleansing composition.
As a preferable embodiment of the moisturizing and cleansing composition, the chelating agent comprises disodium EDTA (0.03-0.1 wt%) and caprylhydroxamic acid (0.21-0.56 wt%) of the moisturizing and cleansing composition.
As a preferable embodiment of the moisturizing and makeup removing composition, the emulsifier comprises 1-3% of sucrose laurate and 0.5-2% of ceteareth-20 by mass of the moisturizing and makeup removing composition.
As a preferred embodiment of the moisturizing cleansing composition, the moisturizing cleansing composition further comprises a solvent accounting for 84.1-93.17% of the mass of the moisturizing cleansing composition.
The solvent is preferably water, and the makeup remover obtained by the moisturizing makeup remover composition and the water has excellent moisturizing makeup remover performance, good stability, no preservative and small irritation to skin.
As a preferred embodiment of the moisturizing cleansing composition, the mass ratio of the sucrose laurate to the ceteareth-20 is (1-3): (0.5-2).
Preferably, the sucrose laurate is under the trade name RYOTO TM SURAR ESTER L-1695; the ceteareth-20 is sold under the trade name
CE 200F。
Preferably, the moisturizing and cleansing composition comprises the following components in percentage by mass: 0.05% of disodium EDTA, 0.28% of caprylhydroxamic acid, 0.06% of caprylyl glycol, 0.06% of glycerin, 8% of 1, 3-propanediol, 2% of sucrose laurate, 1% of ceteareth-20, and the balance water.

The data in Table 3 show that the compositions of the present invention are safe and non-irritating, indicating that the compositions of the present invention employ the food grade emulsifier sucrose laurate (RYOTO) which is a source of natural sucrose having low irritation TM SUGAR ESTER L-1695), and is compounded with caprylyl hydroximic acid, caprylyl glycol and EDTA disodium according to a proper proportion for bacteriostasis, and replaces the traditional preservative for addition, so that the mildness of the composition can be further improved.
2. Makeup removal effect test
The same type of lipstick, eye shadow, eyeliner, mascara, and foundation were applied to the same area of artificial leather, respectively, and after standing for 5min, the test cotton ball was soaked with 1mL of the cleansing water samples of examples 1 to 3 and comparative examples 1 to 9, and the artificial leather coated with the color cosmetic product was wiped off (load 200 g, repeat 10 times), respectively. And recording the makeup removing condition of each makeup removing water sample to be detected on each product, and scoring (0-10 points), wherein the higher the score is, the stronger the makeup removing capability is.
120 female volunteers (age 25-45 years) were randomly selected and divided into 12 groups of 10 persons each, corresponding to the cleansing water samples of examples 1-3 and comparative examples 1-9, and subjected to the use test. The evaluators apply equal amount of samples on the arms respectively, and score the refreshing degree and the moistening degree in the application process of the samples (1-10 points, the higher the score is, the better the refreshing degree or the moistening degree is), and calculate the average value by summing up the scores of all the evaluators, and the result is shown in table 4.
TABLE 4 cleansing effect and skin feel test results of examples and comparative examples
The data in Table 4 show that the compositions of examples 1-3 of the present invention provide effective removal of lipstick, foundation, eye shadow, eyeliner, mascara, and provide good skin feel, freshness and moisturization. Shows that the invention adopts the emulsifier sucrose laurate (RYOTO) TM SURAR ESTER L-1695) and ceteareth-20 (
CE 200F) are combined according to a proper proportion to perform synergistic interaction, and the cleaning agent has excellent cleaning effect on different types of color cosmetics.
While the compositions of comparative examples 1 and 2, which contain only one emulsifier, are poor in makeup removal ability and skin feel. The emulsifier of comparative example 3 was glycerol triisostearate, which was poor in makeup removal effect. The comparative examples 4 and 5 adopt the glycerol triisostearate to be compounded with the emulsifier with single component, and the makeup removing effect is inferior to that of the examples, which shows that the emulsifier component has excellent synergistic effect and can have obvious makeup removing effect when being matched with the emulsifier component. In comparative example 6, the sucrose laurate emulsifier was not added, and the same amount of the preservative was added, so that the skin irritation was large and the makeup removing effect was poor. In comparative example 7, sucrose laurate was not completely dissolved and the makeup removing ability was insufficient. The lower ceteareth-20 content in comparative example 8 and the lower sucrose laurate content in comparative example 9 resulted in poor formulation between the two, resulting in reduced make-up removal and poor skin feel in comparative example 8 and comparative example 9. The composition disclosed by the invention can achieve a bacteriostatic effect by compounding the moisturizing component and the emulsifier without adding a preservative, and has an excellent makeup removing result.
3. Test of moisturizing Effect
Because water has high permittivity, the hydration degree of the skin surface layer, namely the water content of the stratum corneum can be measured by the permittivity, and therefore, the skin moisture detection is carried out by a CORNEOMETER-capacitance method. A skin moisture tester CM825 of German CK company is used for measuring the moisture content of skin, the measurement process of a skin moisture measurement value is greatly influenced by the ambient temperature and the ambient humidity, the ambient test condition is controlled to be 20 ℃ and 50% relative humidity, the moisture tester probe is vertically pressed on the surface of the skin to be tested during the test, the top of the probe is pressed back for a certain distance, a spring is arranged in the probe to ensure that the top of the probe keeps 0.16N of pressure and presses on the surface of the skin, and the skin moisture tester can test the skin moisture content under the normal room temperature condition (the temperature is 20 ℃ and the relative humidity is 40% -60%).
The specific detection method comprises the following steps: 140 healthy skin female volunteers aged 20-50 years were selected for testing, randomly divided into 14 groups of 10 persons each, using the products of examples 1-3 and comparative examples 1-9, negative control (purified water), and positive control (Bei Dema (BIODERMA) cleansing water), respectively. In the environment with the temperature of 20 +/-1 ℃ and the air humidity of about 50 percent, after the same simple cleaning and skin care, 14 groups respectively correspond to 14 test samples according to the proportion of 1mg/cm 2 The test specimen was applied to the inside of the arm. After the subject was rested in a constant environment for 30 minutes, the test site blank value was measured using a Corneometer, and 5 points were fixedly measured using the area in a certain order to obtain an average value thereof. Then a specially-assigned person is responsible for smearing the sample, timing is started, the change of the humidity measurement value is measured at each time according to the design of the experiment, and the change of the skin humidity measurement value within 8h of each combination ratio is tested and recorded by using a Corneometer CM 825.
Table 5 moisturizing effect test results of examples and comparative examples
The results in Table 5 show that the compositions of examples 1 to 3 of the present invention have a good moisturizing effect, which indicates that the combination of sucrose laurate emulsifier and ceteareth-20 emulsifier in the present invention can provide a good moisturizing effect by reducing the loss of moisture through skin, and avoid the phenomena of easy drying and tightening after makeup removal with common makeup remover water. The moisturizing effects of the compositions of comparative examples 1-9 are all inferior to those of examples 1-3, indicating that the compositions of the present invention have excellent synergistic effects and excellent moisturizing properties while ensuring sufficient cleansing power.
4. Appearance observation
Comparing the makeup remover of example 1 with that of comparative example 7: example 1 normal temperature 25 ℃, transparent and not layering; comparative example 7 was transparent at 25 ℃ at room temperature, but the upper layer was oily and the lower layer was water, and the layers were separated.
The side shows that the sucrose laurate emulsifier is easy to agglomerate in water at normal temperature and is difficult to dissolve, and the problem of difficult dissolution in water can be solved by a special solubilization process (mixing the sucrose laurate emulsifier with 1,3-propylene glycol and ceteareth-20 emulsifier and heating to 75-80 ℃).
