Description

Micelle composition and preparation method and application thereof

Technical Field

The invention belongs to the field of cosmetics, and relates to a micelle composition, and a preparation method and application thereof.

Background

With the improvement of living standard, the makeup is an indispensable step in daily life of modern women. And the cleaning after the makeup is the most critical step for skin care. Therefore, consumers are demanding more and more on facial cleansing products, which not only require a combination of quick cleansing, deep cleansing, makeup removal, skin care, etc., but also require mildness, no irritation, convenience of use, etc.

The facial cleaning products on the market at present can be divided into two types, namely makeup removing products and face cleaning products. First, the makeup removing product can be divided into four types of makeup removing oil, makeup removing cream and makeup removing liquid. Cleansing oil, cleansing cream and cleansing cream have strong cleansing capability but oily skin feel and poor experience. The cleansing water is popular with consumers due to the characteristics of fresh skin feel, convenient use, no need of water washing and the like, but the commercially available cleansing water has the defects of weak cleansing capability, eye irritation, dryness after use and the like, so that the further expansion of the cleansing water market is limited. Secondly, the face cleaning product can be divided into five types of face cleaning milk, face cleaning cream, face cleaning gel, face cleaning mousse and face cleaning powder. However, the face cleaning product is limited to the cleaning of dirt on the surface of the face, has poor effect on removing makeup on the face, is particularly not suitable for removing eye makeup, and is easy to stimulate eyes. Therefore, the development of a cleaning product which has the effects of cleaning and removing makeup, has rich and fine foam, is mild and non-irritating and has the skin-care effect has very important practical significance.

Micelles are one of colloidal dispersions, and belong to associative colloids. The particle size of the micelle is usually below 200nm, and belongs to a transition region from macro to micro of a substance. Due to the special structure of the micelle, the micelle has the following characteristics: small size effects, surface and interface effects, quantum size effects, and macroscopic quantum tunneling effects, and have many special properties not possessed by conventional substances. Therefore, compared with the traditional product, the cleansing product with good cleansing and makeup removing effects, rich and fine foam, rich foam and mild property is expected to be prepared.

Most of the micellar products on the market today are single effect micellar water, although mild and low irritative, but without foam. The mousse products on the market almost have simple facial cleaning effect and no makeup removing effect, and if the mousse products have obvious makeup removing effect in use, the mousse products need to use a surfactant with higher content, so that stimulation is easily caused, and the skin is easily damaged.

CN106726770A discloses a makeup removing micelle composition, a preparation method thereof and application thereof in makeup removing water, wherein the makeup removing micelle composition comprises the following components in percentage by mass: 0.1-20% of modified grease containing polyethylene glycol chain segments, 0.1-20% of nonionic surfactant, 0.1-10% of dipropylene glycol and the balance of water. The preparation method of the makeup removing micelle composition comprises the following steps: mixing polyethylene glycol modified grease, a nonionic surfactant and dipropylene glycol in a water medium according to a proportion to form a micelle composition; the makeup removing micelle composition forms a micelle solution with a certain particle size range, reduces the use amount of the modified grease, effectively removes makeup and simultaneously reduces the stimulation of the modified grease on skin due to permeation; the micelle composition can be used for preparing mild and non-irritant makeup remover, can be used for removing makeup on eye and lips, and has the advantages of good makeup removing effect, convenience in use, no need of water washing, and no dryness or tightness after use.

CN102791255A discloses a micelle composition comprising a hydrophobic compound and an amphiphilic block copolymer, wherein the amphiphilic block copolymer consists of a hydrophobic block a comprising at least one hydrophobic polymer unit X and a hydrophilic block B comprising at least one hydrophilic polymer unit Y, wherein the X blocks and the Y blocks alternate. The micelle composition can be used in the following applications: medical applications (such as cardiovascular therapy applications), veterinary applications, food processing applications, flame retardant applications, coatings, adhesives and cosmetic, textile/textile, industrial and artistic applications.

CN109260030A discloses a micelle composition, a preparation method and an application thereof, which comprises the following components in parts by weight: 20-60 parts of polyglycerol and/or polyethylene glycol surfactant, 20-60 parts of regulator and 0-60 parts of amphoteric surfactant, wherein the regulator comprises at least one of saccharide regulator, glucoside regulator and polyalcohol regulator. The micelle composition has mild components, no irritation to skin and good moisture retention. The functions of all components are fully exerted by utilizing the mutual influence among all the components and through reasonable control and scientific collocation of the adding amount of all the components. The cleaning and skin-care product can be applied to cleaning and skin-care products, and can relieve the problems of poor decontamination capability, skin irritation and low cost performance of the existing cleaning and skin-care products.

Therefore, how to develop a micelle composition which has two effects of makeup removal and cleaning, and also has the effects of mildness, low stimulation and rich and fine foam has important value for facial cleaning.

Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide a micelle composition, a preparation method and application thereof, and solves the problems of no foam, single effect and high irritation of the existing micelle composition.

In order to achieve the purpose, the invention adopts the following technical scheme:

in a first aspect, the present invention provides a micelle composition, which comprises the following components by mass: 0.1-15% of modified grease containing polyethylene glycol chain segment, 0.1-50% of surfactant, 0.1-10% of glycerol and the balance of water.

According to the micelle composition provided by the invention, the modified grease containing the polyethylene glycol chain segment, the surfactant and the glycerol are reasonably matched, so that the micelle has uniform particle size distribution, can generate fine foam appearance, has the functions of cleaning and makeup removing by virtue of a lower matching amount, reduces the stimulation caused by the surfactant, and has mild properties.

Preferably, the micelle composition comprises the following components in percentage by mass: 3-8% of modified grease containing polyethylene glycol chain segments, 32-40% of surfactant, 6-9% of glycerol and the balance of water.

The modified oil or fat containing a polyethylene glycol segment of the present invention may be, for example, 0.1% to 15% by mass, for example, 0.1%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14% or 15%.

Preferably, the modified grease containing the polyethylene glycol chain segment comprises PEG-75 shea butter glyceride.

The lipophilicity of the PEG-75 shea butter glyceride is far greater than that of the PEG-75 shea butter glyceride, the PEG-75 shea butter glyceride has certain capability of dissolving color cosmetics, meanwhile, the persistence of foam can be increased, the foam is more dense and fine, the permeability is weaker, and the stimulation to the skin can be reduced. Whereas if too much is used, the consistency of the product is increased, which affects the appearance of the product, and if less is used, the foam-sustaining ability is poor, so that the concentration range thereof needs to be selected specifically.

The modified grease containing the polyethylene glycol chain segment is not limited to the types, but can also be PEG-6 caprylic/capric glycerides, PEG-7 glyceryl cocoate, olive oil PEG-7 lipids and the like. However, these types of modified fats and oils are inferior in foaming effect.

The surfactant of the present invention may be 0.1% to 50% by mass, for example, 0.1%, 1%, 2%, 3%, 4%, 5%, 6%, 10%, 12%, 15%, 20%, 23%, 24%, 30%, 32%, 36%, 40%, 42%, 45%, or 50%.

Preferably, the surfactant comprises any one of PEG-8 glyceryl isostearate, sodium lauryl glucose carboxylate, sodium cocoyl methyl taurate, guar hydroxypropyltrimonium chloride, disodium lauryl sulfosuccinate, disodium cocomonoethanolamide sulfosuccinate, potassium monododecyl phosphate, cocamidopropyl betaine, lauramidopropyl hydroxysultaine, sodium lauryl amphoacetate, or a combination of at least two thereof.

In the present invention, there are many surfactants that can be selected, but different selection of surfactants or combinations thereof will have different effects on the performance of the micelle composition. For example, decyl glucoside, polyglycerin-10 laurate, polyglycerin-10 oleate, and the like are also possible.

Preferably, the surfactant is a combination of PEG-8 glyceryl isostearate, sodium lauryl glucarate and sodium cocoyl methyl taurate.

In the invention, three substances, namely PEG-8 glyceryl isostearate, sodium lauryl glucose carboxylate and sodium cocoyl methyl taurate have better hydrophilic and oleophilic effects, are mild in property and less in skin irritation, and can easily form micelles in a water base, and the micelle solution with a certain particle size range is formed by compounding the micelle solution with modified grease containing polyethylene glycol, so that the capability of dissolving color cosmetics by the modified grease can be enhanced, the using amount of the modified grease is reduced, and the irritation of the modified grease to the skin due to permeation is reduced.

The PEG-8 glyceryl isostearate, the sodium lauryl glucose carboxylate and the sodium cocoyl methyl taurate are matched for use, so that the effect is optimal, wherein the two salt substances of the sodium lauryl glucose carboxylate and the sodium cocoyl methyl taurate increase the density of the micelle composition, and the generated foam is more durable after being matched with the PEG-8 glyceryl isostearate. The absence of either or both of these three surfactants can degrade the performance of the micelle composition.

The glycerin of the present invention may be 0.1% to 10% by mass, for example, 0.1%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10%.

The glycerin has better intersolubility with water and oil, has little irritation to skin and has certain moisturizing effect. The addition of the glycerol is beneficial to the formation of system micelles, improves the stability of the micelle composition and has a gain effect on the skin care effect of the composition. Compared with dipropylene glycol, the foam stability of the micelle composition is more favorable.

As a preferred technical scheme, the micelle composition comprises the following components in percentage by mass: 5% of PEG-75 shea butter glyceride, 8% of PEG-8 glyceryl isostearate, 18% of sodium lauryl glucose carboxylate, 10% of sodium cocoyl methyl taurate, 8% of glycerin and the balance of water.

The micelle composition provided by the preferred technical scheme has the best performance.

In a second aspect, the present invention provides a method for preparing the micelle composition according to the first aspect, the method comprising: mixing modified grease containing polyethylene glycol chain segments, a surfactant, glycerol and water, heating, and cooling to obtain the micelle composition.

In the invention, through the process of heating and cooling, the PEG-75 shea butter glyceride which is originally solid can be fully mixed with the surfactant, the glycerol and the water, and the mixture is fully dispersed, so that the formed micelle foam has better effect. However, if the preparation is carried out only at normal temperature, a micelle composition which is uniformly mixed and has a good foaming effect cannot be obtained.

The preparation method of the micelle composition provided by the invention is energy-saving and simple, has stable process, and can be widely popularized and applied.

Preferably, the temperature is raised to 60 to 80 ℃, for example, 60 ℃, 62 ℃, 63 ℃, 65 ℃, 70 ℃, 72 ℃, 75 ℃, 78 ℃, 79 ℃ or 80 ℃, preferably 65 ℃.

Preferably, the temperature increase is performed in a stirred state.

Application example

The micelle composition provided in example 1 was prepared into 4 face-cleansing mousses, and the specific formulations and percentage (%) compositions are shown in table 1 below:

TABLE 1

Wherein the meanings of the appropriate amounts in table 1 are as follows: the content of the preservative and the flavoring agent can be properly adjusted by the person skilled in the art according to the actual situation; the balance is supplemented by water.

The preparation method of the face cleaning mousse comprises the following steps: (1) weighing water, EDTA disodium and PCA sodium in proportion, sequentially adding into a vacuum emulsifying pot, heating to 80 deg.C, stirring to completely mix and dissolve, keeping the temperature for 10min, and cooling.

(2) Heating the micelle composition to 65 ℃, and dissolving the micelle composition completely and transparently for later use.

(3) When the temperature of the system is reduced to 45 ℃, the cleaning micelle composition is added and stirred uniformly, and then the preservative and the aromatizer are added in sequence and stirred uniformly.

(4) And after detection, qualified stirring and discharging to obtain the 4 kinds of face cleaning mousses.

Further, a commercially available facial mousse of a certain well-known brand was used as a comparative example, and its components included water, glycerin, maltitol, propylene glycol, polyethylene glycol-150, sodium cocoyl glutamate, sodium lauroyl aspartate, lauryl hydroxysulfobetaine, polysorbate-60, disodium EDTA, dipotassium glycyrrhizinate, potassium hydroxide, methylparaben, phenoxyethanol.

The 4 cleansing mousses a, b, c and d in the application examples and the comparative examples are subjected to erythrocyte hemolysis test, cleaning effect evaluation and particle size detection, and the details are as follows:

experimental example 1

Haemolysis test of erythrocytes

The irritation of the test sample to the skin surface was evaluated based on the principle that lipids and proteins on the human skin surface are similar to the cell membrane of red blood cells. The test results were determined according to RBC experimental test method and grading standard of European Alternatives verification center (ECVAM), reference (ECVAM. ECVAM DB-ALM: INVITIONX Protoco, Red blood cells test system. INVITOX No.37 Ispra. Italy: ECVAM, 1994.). The results obtained are shown in table 2 and in fig. 1:

TABLE 2

It is known from the experimental data L/D in table 2 and fig. 1 that the irritation of the sample in which the micelle solution is formed by compounding the surfactant and the water-soluble modified oil by using the micelle technology is greatly reduced, and is close to or reaches the irritation level, and the irritation of the sample in which the non-surfactant and the water-soluble oil are not used for wrapping is more obvious. Comparing the hemolysis rates of the samples, samples a, b, and c to which the clean micelle composition was added showed no more than 0.5% of blood insolubility, while samples d and comparative examples showed no more than 0.01% of blood insolubility, and thus it can be judged that the irritation of samples a, b, and c to which the clean micelle composition was added was much lower than that of comparative examples and samples d.

Experimental example 2

20 female volunteers, aged 25-50 years, were used as study subjects for full face makeup with equal amounts of BB cream (W/O type), eye shadow, and eyeliner lipstick, and then the mousse was used in combination with makeup remover cotton using equal amounts of sample b and a commercially available face-cleaning mousse (surfactant system) with good evaluation. The sample b, a clear mousse for cleansing face, was used for the left face, a commercially available mousse for better evaluation for cleansing face, and skin feel after cleansing and makeup removal were evaluated for the right face. The results are shown in Table 3.

TABLE 3

From the results of this experiment, it was found that the sample b had a cleaner effect and a fresh skin feel after use as compared with the comparative example (a commercially good brand of cleansing mousse), while the comparative example (a commercially good brand of cleansing mousse) had a greasy skin feel after use, had a great irritation to the eyes, and had a part of the makeup staying after washing. When the volunteer uses the sample b to remove the eye color makeup, the eyes hardly feel the irritation. Therefore, the transparent mousse has good face cleaning and makeup removing effects and very fresh and cool use feeling, is mild and non-irritant, and can be used for cleaning faces and removing makeup.

Experimental example 3

Particle size measurement

The micellar composition provided in example 1, sample b and the facial mousse prepared in comparative example were particle size characterized using a HORIBA nanometer particle size analyzer SZ-100 using laser diffraction scattering particle size distribution determination. The results are shown in FIG. 2, FIG. 3 and FIG. 4.

From the figure, the micelle particle size of the micelle composition prepared by the method is 8-60 nm, most of the micelle particle size is distributed around 10nm, even if the micelle composition is added into a formula, the micelle particle size is not obviously changed, the clean micelle composition can be proved to be stably present in the system, meanwhile, the particle size distribution of a sample b added with the micelle composition is proved to be different from that of a comparative example (a certain well-known brand Jiemiu sold in the market), the particle size distribution of the sample b system is relatively single, and the particle size of the comparative example is relatively complex.

Tests of experimental examples 1-3 show that the facial mousse prepared from the micelle composition provided by the invention has lower irritation, more uniform particle size distribution and better skin feeling effect compared with the commercial products. And demonstrates that when the micelle composition does not contain PEG-75 shea butter glyceride, the performance of the micelle composition is reduced and the stimulation is improved.

Experimental example 4

The micelle compositions provided in examples 1 to 9 and comparative examples 1 to 6 were subjected to a foam effect test and a irritation test.

Wherein the irritation test was the same as in Experimental example 1, and the erythrocyte hemolysis test was used to measure the irritation of the micelle composition.

The method for testing the foam effect comprises the following steps: and (5) packing the material by using the same pressure pump, and comparing the foam quantity by using the same force and pressing times.

The specific test results are shown in table 4:

TABLE 4

As is clear from the results in Table 4, the absence of one or both of the surfactants in examples 5 to 7 worsens the foaming effect, and particularly, in the absence of both sodium salts, no foam is generated; comparative example 2 did not contain a surfactant and did not have a foaming effect.

In examples 8-9, the foaming effect was poor when micelle compositions were prepared by replacing PEG-75 shea butter glycerides and surfactants with other ingredients. The choice of surfactant has a greater effect on the foaming effect.

Comparative example 1 is also suspected of foaming when PEG-75 shea butter glycerides are not present; but fails to foam when the surfactant is not contained or is largely changed.

It can also be seen in comparative examples 3-5 that glycerol promotes foaming of the micelle composition; the varying levels of PEG-75 shea butter glycerides and surfactants results in a reduction in foaming.

The micelle composition provided in comparative example 6 has no effect of foaming, although it has low irritation.

The applicant states that the present invention is illustrated by the above examples of the micelle composition of the present invention and the preparation method and application thereof, but the present invention is not limited to the above process steps, i.e. it does not mean that the present invention must rely on the above process steps to be carried out. It will be apparent to those skilled in the art that any modification of the present invention, equivalent substitutions of selected materials and additions of auxiliary components, selection of specific modes and the like, which are within the scope and disclosure of the present invention, are contemplated by the present invention.
