Description
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a makeup removing composition.
Background
With the development of society and the improvement of living standard, the pursuit of beauty is more and more emphasized, and along with this, the frequency of using color cosmetics such as lipstick, foundation make-up, etc. is also more and more increased. Because of the product characteristics, if the product is not cleaned in time after being used, the oil or pigment particles coated on the skin can block pores, and further skin problems can be caused. Therefore, more and more attention is paid to makeup removing products with higher makeup removing capability.
The technical scheme adopted by the makeup removing product is that components such as a surfactant, grease, an additive, a solvent and the like are combined, so that products such as a makeup removing solution, a multi-layer makeup removing solution, a makeup removing rod, a makeup removing wet tissue, a makeup removing gel and the like are developed, and the makeup removing product is greatly convenient for customers to use while providing good makeup removing capability. The components of the cosmetic are analyzed, and the cosmetic for removing the cosmetics mainly comprises grease and a surfactant, wherein the grease provides the capability of dissolving oil and pigment in the cosmetics, and the surfactant provides the effect of removing the grease. Further analysis shows that the composition of the oil phase has an influence on the makeup removing capability and even the skin feel: for example, vegetable oils have poor pigment-dissolving ability and good affinity with skin, which leads to easy residue on skin; synthetic oils and fats such as isononyl isononanoate, cetyl ethylhexanoate and the like have solved the problem of oil residues on the skin, but their pigment-dissolving ability is still somewhat unsatisfactory. Therefore, when the makeup remover composition has an unreasonable oil phase composition and ratio, the pigment cannot be well dissolved, and residue is caused, so that a consumer feels greasy after using the makeup remover composition, and new skin problems may be caused by the oil residue.
Therefore, starting from the oil phase composition, a new oil component which has better dissolving capacity for makeup and can be matched with other oil phase components and synergized and has better washing capacity is searched and applied to the makeup removing composition, so that a rich makeup removing product with better makeup removing capacity is provided, and the oil-based makeup removing composition has potential application value.
Disclosure of Invention
In order to solve the technical problems, the invention provides a makeup removing composition. The invention applies the sarcosine ester with a specific structure to the makeup removing products, and can obtain different types of makeup removing products with better makeup removing capability.
In order to achieve the purpose, the invention adopts the technical scheme that:
the makeup removing composition is characterized by comprising the following components:
a. a sarcosinate having the structure:
wherein R1 is C9-17 straight chain or branched chain alkyl, and R2 is C2-C5 straight chain or branched chain alkyl;
b. a surfactant.
The oil and the surfactant in the makeup removing composition are key components in the formula, and the sarcosine ester conforming to the structure has surprising makeup removing capability and better makeup removing capability than the grease commonly used in the existing makeup removing products, such as caprylic/capric triglyceride, macadamia nut oil, isononyl isononanoate, hexadecyl ethyl hexanoate, isopropyl palmitate and the like. Meanwhile, the sarcosine ester and the common grease have better compounding capability, and the makeup removing effect of the common grease, such as caprylic acid/capric acid triglyceride, is improved. Further, the sarcosine ester can be compounded with non-polar grease, such as alkane and the like, and the obtained composition can show better makeup removing capability.
Sarcosine esters have a good makeup removing ability, which is related to their own structure. On one hand, the longer alkyl chain on the R1 side in the structure of the cosmetic has better non-polar characteristic, and according to the similar compatibility theory, the cosmetic can be well inserted into oil of the color cosmetics, so that pigments and grease in the color cosmetics are dissolved and dispersed, the color cosmetics fixed on the surface of skin are loose, and the aim of easy washing is achieved. The short alkyl chain in the R2 group on the other side ensures that the oil has good spreadability and can be easily spread on the surface of skin. On the other hand, compared with other oil phase components, the structure of the sarcosine ester contains an amide group, so that the sarcosine ester has special polarity characteristics; when the surfactant exists, the ester can be better dissolved by the surfactant, and further brings away the substances which are difficult to dissolve in the color cosmetics. The esters have potential advantages in removing color cosmetics under the combined action of the two aspects.

In order to evaluate the makeup removing capability of the makeup removing composition and compare the makeup removing capability with that of different compositions, so as to illustrate the advantages and the technical effects of the composition, the quantitative evaluation method of the makeup removing capability is adopted in the invention, in brief, makeup color is coated on simulated skin (BioSkin Plate), then makeup removing experiments are carried out by using the composition to be evaluated, photos of sample areas before and after makeup removing are shot by a camera, lab values of the evaluation areas in the photos are extracted by software Matlab, and the color difference change percentage of the sample areas before and after makeup removing is calculated, namely the makeup removing index of the composition is defined.
The color makeup is smeared on the skin and forms color difference with the skin, and the conventional evaluation of makeup removing capability depends on the observation of naked eyes, so that the size and the difference of the makeup removing capability of the product cannot be quantitatively described. According to the color difference change, searching the related color theory and calculation method to find the color mode CIE L * a * b * It is well matched that, by definition, each color has a fixed coordinate point (L) in three-dimensional color space * ,a * ,b * ) Wherein L is * Represents lightness, a * Representing red green, b * Indicating yellow blue. The spatial distance (Δ E) of any two points can quantitatively express the change of color, and further corresponds to the amount of color makeup applied or removed. Meanwhile, in order to more conveniently process and calculate the value of the sample, a simulated skin (BioSkin Plate) is adopted, and the experiment can be rapidly carried out under the condition of ensuring the similarity with the human skin.
For the makeup removal method, the L of the skin before and after applying the makeup can be firstly tested * a * b * Value, calculating the spatial distance (Δ E) between the two Before makeup removal ) Quantifying the smear amount of the indicated sample by using the spatial variation; then, the sample area is subjected to makeup removal treatment, and L is recorded * a * b * Value, and calculating the change in color space distance (Δ E) from the pre-makeup removal After makeup removal ). And then calculating the proportion of the makeup removing product to the makeup removing product before makeup removing to obtain a quantified numerical value of the makeup removing index, so as to better evaluate the makeup removing capability of the product.
The key of the method is to accurately obtain the L of the sample area * a * b * To this end, a method of processing an image with software Matlab by taking a picture with a digital camera is used. In order to ensure the accuracy of data, sample shooting is carried out in a light box, and errors are reduced to the maximum extent through fixing light brightness, sample positions, shooting positions and camera parameters, so that the accuracy of the data is ensured.
The procedure for evaluating the makeup removing ability of the makeup removing composition was:
(1) Drawing a specific area on a simulated skin (BioSkin Plate), and taking a picture in a standard light box by using a camera before color cosmetics are not coated;
(2) Uniformly coating color makeup on the drawn specific area; after drying for a period of time, taking a picture in a standard light box by using a camera;
(3) Weighing the makeup removing composition to be evaluated on makeup removing cotton, repeatedly wiping the makeup removing cotton for a fixed number of times in a test area, and shooting a photo in a standard light box again;
(4) L of shot picture test area before and after makeup removal is extracted by software matlab * a * b * A value;
(5) According to L * a * b * And (4) calculating the color change of the test area before and after makeup removal to obtain the makeup removal index of the makeup removal composition.
In the following examples, the specific test method for the makeup removing ability of the makeup removing composition was:
the instrument equipment comprises:

3. Camera setting: a Nikon D80 digital camera, fixed aperture, ISO, focal length and shooting position;
4. data extraction: extracting L of a test area by utilizing srgb2lab function in software Matlab * a * b * The value is obtained.
And (3) testing:
1. shooting the blank skin in a light box, and recording as 'blank';
2. selecting a 2cm × 3cm area on simulated Skin (Bio Skin Panel), uniformly applying lipstick and mascara respectively, air-drying for 90min, and shooting with a light box, wherein the area is marked as front, as shown in the left picture of an example figure 1;
3. 0.5g of make-up removing composition is weighed on a make-up removing cotton, a 100g weight object (instead of being pressed by a finger) is placed on the make-up removing cotton, the sample area is repeatedly wiped five times, the sample area is dried for 10min, and a light box is used for shooting, which is recorded as 'after', as the right picture of the example figure 1.
4. L of sample area pictures before and after makeup removal is extracted by utilizing Matlab software * a * b * And then calculating the makeup removing capacity of the sample on makeup according to the following formula, wherein the makeup removing capacity is the makeup removing index:
wherein "front" represents the numerical value of the sample area before makeup removal;
"Back" represents the numerical value of the sample area after makeup removal;
"empty" represents the value of the skin area before the color cosmetic is applied.
The larger the makeup removal index value, the stronger the makeup removal ability of the sample.
All data are the average of three replicates.
The invention concretely implements the makeup removing composition containing the sarcosine ester, in particular to the sarcosine ester of which R1 is C11-15 alkyl and R2 is C2-3 alkyl, and evaluates the makeup removing capability of the composition. On the whole, the makeup removing capability of the sarcosine ester in the composition is better than that of common polar monoester or triglyceride, and the sarcosine ester has better compounding capability with polar grease and improves the makeup removing effect. If the sarcosine ester is compounded with nonpolar oil, especially alkane, the makeup removing capability is better. For brevity and convenience, the following description will be given using isopropyl lauroyl sarcosinate as an example. The specific structural formula of the sarcosinate is as follows:
using the trade name Evertouch by Sino Lion corporation TM Isopropyl lauroyl sarcosinate sold by LPS-100.
Example 1, comparative examples 1 to 5
Example 1 a makeup remover composition containing sarcosinate was prepared, the composition of which is shown in table 1. The form is a double-layer makeup remover (example 1), namely the sample can be divided into an oil layer and an oil layer under normal conditions and can be directly shaken up when in use.
For comparison, makeup removing compositions (comparative examples 1 to 5) were prepared using conventional polar oils including caprylic/capric triglyceride, isononyl isononanoate, cetyl ethylhexanoate, isopropyl palmitate, jojoba oil, respectively, in the same mass percentage composition as in example 1, except that the polar oils were used instead of isopropyl lauroyl sarcosinate in the compositions. Specific arrangement ratios are shown in table 1, for example.
The makeup removal indexes of example 1 and comparative examples 1 to 5 were measured by the test methods as described above, and the results are shown in table 1.
TABLE 1 cleansing compositions containing isopropyl lauroyl sarcosinate and conventional polar fats and oils and cleansing compositions having cleansing power thereof
Makeup removal capability test data
* Represents p<0.05, statistically representing a difference, ** represents p<0.01, statistically representing significant differences
Test results show that the isopropyl lauroyl sarcosinate has remarkable advantages in the makeup removing capability of lipstick under the conditions of unchanged combination and proportion of other components in the formula and the same oil phase proportion, the makeup removing index is obviously higher than that of other oils, and the makeup removing capability is remarkably different from that of jojoba seed oil and caprylic/capric triglyceride. The makeup removing ability of the mascara is higher than that of other kinds of oils, in addition to being lower than that of isopropyl palmitate (comparative example 4, no statistical difference). The experimental results fully indicate that isopropyl lauroyl sarcosinate has better makeup removing capability than the conventional polar grease.
Examples 2 to 3
The oil phase components were kept constant in total content, the ratio of isopropyl lauroyl sarcosinate to caprylic/capric triglyceride was adjusted, and the makeup removing compositions (shown in table 2) were prepared separately in the same mass percentage as in example 1, and the makeup removing index of each makeup removing composition was determined.
TABLE 2 make-up removing composition comprising isopropyl lauroyl sarcosinate in combination with caprylic/capric triglyceride and make-up removing composition having make-up removing ability thereof
Makeup removal capability test data
** Represents p<0.01, statistically representing significant differences
From the data, the small amount of caprylic/capric triglyceride compounded with isopropyl lauroyl sarcosinate can obviously improve the makeup removal index of lipstick and mascara (example 2 and comparative example 5); as the formulation ratio increased (example 3), the lipstick makeup removal index continued to increase, while the makeup removal index continued to increase for mascara had little effect. Test results show that the isopropyl lauroyl sarcosinate and the polar grease have good compounding capability, and the makeup removing capability of the polar grease can be improved.
Examples 4 to 6, comparative example 6
In the makeup removing product, besides polar grease, there is a class of nonpolar grease, so the makeup removing composition is prepared by taking alkane and silicone oil as representatives, controlling the total content of oil phase components to be unchanged, compounding isopropyl lauroyl sarcosinate and different types of nonpolar grease according to the proportion of 1. And the makeup removal index of each makeup removal composition is determined by using the makeup removal test method.
TABLE 3 make-up removing composition comprising isopropyl lauroyl sarcosinate in combination with different nonpolar oils and make-up removing composition having makeup removing ability
Makeup removal capability test data
* Represents p<0.05, statistically representing a difference, ** represents p<0.01, statistically representing significant differences
From the data, the combination effect of the nonpolar oil (examples 4, 5 and 6) and the isopropyl lauroyl sarcosinate is better, and the makeup removing capability of the isopropyl lauroyl sarcosinate on mascara can be particularly obviously improved. The nonpolar alkane can also improve the makeup removing capability of isopropyl lauroyl sarcosinate on lipstick, but the makeup removing effect of isopropyl lauroyl sarcosinate can be basically achieved after the nonpolar siloxane (example 6) is compounded, and the improvement efficiency on lipstick is not particularly obvious. Therefore, the test result shows that the isopropyl lauroyl sarcosinate has better compounding capability with the nonpolar oil.
Examples 7 to 10
The results show that the makeup removing capability of the composition of the isopropyl lauroyl sarcosinate is improved by compounding the alkane and the isopropyl lauroyl sarcosinate, but the influence of the alkane proportion on the performance of the composition still needs to be considered, so that the total content of the oil phase components is kept unchanged, and the influence of the composition and the content of the oil phase of the alkane and the isopropyl lauroyl sarcosinate on the makeup removing capability of the makeup removing composition is researched. Here, isohexadecane and isopropyl lauroyl sarcosinate were selected and compounded at different ratios to prepare makeup remover compositions of examples 7 to 10 (Table 4), and the makeup remover indices of the respective makeup remover compositions were measured.
TABLE 4 make-up removing composition containing isopropyl lauroyl sarcosinate and isohexadecane combination and make-up removing capability thereof
Makeup removal capability test data
From the data, keeping the total content of the oil phase components constant, the makeup removal index of the makeup removing composition on the mascara and the lipstick shows a trend of increasing first and then decreasing with the increase of the isohexadecane ratio: when the proportion of isohexadecane in the oil phase reaches 90% (example 7), the overall cleansing performance index of the composition is now reduced. One important reason is that when the alkane is increased, the non-polarity of the system is increased, so that the non-polar substances in the color cosmetics can be better dissolved; when the alkane proportion is higher, the polarity of the system is weakened, so that the solvent capacity of polar components in the composition and the color makeup is reduced, and the makeup removing capacity of the system is reduced. The experimental result shows that although the nonpolar alkane and the isopropyl lauroyl sarcosine have better compounding capability, a proper proportion exists between the nonpolar alkane and the isopropyl lauroyl sarcosine, namely the alkane accounts for 30 to 50 percent of the optimal proportion of the oil phase.
Other embodied makeup removing compositions of sarcosinate have similar performance characteristics. The above examples fully illustrate that structurally defined sarcosinates, represented by isopropyl lauroyl sarcosinate, have the following characteristics: the makeup removing capability is superior to that of the common polar grease; can be compounded with common polar grease and improve the makeup removal performance; can be compounded with non-polar grease, and can improve the makeup removing capability of the sarcosine ester.
Examples 11 to 13
Preparing different types of makeup removing compositions, wherein in example 11, the makeup removing composition is a double-layer makeup removing liquid which is normally placed under oil-water layering and is shaken up when in use; example 12 a makeup remover composition with a uniform and stable system, i.e. a bicontinuous makeup remover, was prepared by controlling the ratio of alcohol, surfactant, water, and oil; example 13 cleansing oil, a makeup removing product, is an anhydrous system. The specific formulation ratios are shown in table 5, for example, and are compared to the makeup removal indices of commercially available makeup removal products.
TABLE 5 three types of makeup removing compositions and makeup removing ability thereof
Makeup removal capability test data
* Represents p<0.05, statistically representing differences, ** represents p<0.01, statistically representing significant differences
The test results show that the makeup removal indexes of the different types of makeup removal compositions of examples 11-13 are better than those of market samples, which indicates that the compositions applied according to the invention have better makeup removal capability and can provide better makeup removal products for consumers.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalent changes made to the above embodiment according to the technical spirit of the present invention still belong to the protection scope of the technical solution of the present invention.
