Description

The present invention has a high detergency for makeup, particularly liquid foundation, mascara, oil-based gel eyeliner, and other makeup products that have high detergency, and can quickly remove makeup from the skin, and can be washed away cleanly. It is a viscous cleansing cosmetic with an ass structure. Further, the present invention relates to a technique for increasing viscosity while maintaining a bicontinuous structure that is easy to use without spilling from the hand or dripping when applied to the skin.

In makeup cleansing, it is desired to apply makeup cleansing to the skin, quickly remove makeup from the skin, and reduce the burden on the skin during use.

In order to solve these problems, there is a cleansing oil that can be washed away. This contains 50% or more of liquid oil and further contains a hydrophilic surfactant. When washing away with water, the hydrophilic surfactant imparts washability so that it can be washed out after emulsifying the oil component mixed with makeup or dirt.

However, cleansing oil containing a large amount of oil feels oily and uncomfortable when used. Moreover, since the emulsion which arises when the oil component mixed with makeup and dirt is washed away with water is easy to be gelled, it gives a slimy feeling on the skin. Further, since cleansing oil is generally a low-viscosity liquid, it spills from the hand during application or drops on the applied face, and thus has a problem that it is difficult to apply and poor in usability.

In order to eliminate the oiliness of cleansing oil, an isotropic one-phase (bi-continuous structure) cleaning composition that balances oily components and water-soluble solvents has also been proposed. (Patent Document 1), it is said that both oily and aqueous stains can be removed. However, in these detergent compositions, although the oiliness is reduced, the viscosity of the preparation is low and the problem of dripping seen in cleansing oil is not solved. In addition, since lauryl group or tetradecyl group and an ester or ether of a hydrophilic substance, lauryl alcohol, or lauric acid are blended, there is a problem of safety and usability such as pain when in contact with eyes.
In general, the bicontinuous structure requires that the blending components of surfactant, oil component, and water be delicately balanced, and the preferred blending ratio is not wide. / O, O / W, highly viscous gel, and the like. Each cleansing cosmetic is unsatisfactory compared to the bicontinuous structure. When actually developing a formulation, first create a simple phase diagram with the surfactant, oil, and purified water to be used, and then consider the effect of the blended raw materials, assuming that the bicontinuous structure is stable. However, it is often a delicate development.

In view of this, there has been proposed a method of increasing the viscosity at a specific component ratio while maintaining an isotropic one-liquid phase (bicontinuous structure). In Patent Document 2, a cleansing cosmetic containing a silicone oil component and a volatile hydrocarbon oil component in a specific ratio and further containing a divalent glycol, polyoxyethylene glyceryl isostearate and water is 100 to 500 mPa.s. The viscosity of s is realized. However, in order to actually prevent the sagging, 500 mPa · s. It is thought that there are many cases where it cannot be said that the viscosity is sufficiently increased at s. Although it depends on the use conditions, it is generally 1000 mPa.s. About s seems necessary. The viscosity range of the thickening composition is 100 to 500 mPa.s. It must be said that versatility is low because it is narrow as s.

In general, compositions that are low viscosity liquids are often inconvenient because they spill out of their hands during use or flow without being held in the place where they are applied. Therefore, by thickening, it is assumed that it can be adapted to various containers and usage scenes, but the composition of the bicontinuous structure was thickened with carboxyvinyl polymer, which is a general thickener. In this case, the balance is lost and the emulsion becomes O / W type emulsification, so that the bicontinuous structure cannot be maintained. In addition, when it is thickened with xanthan gum or a cellulose-based thickener widely used as a thickener, it sticks to the skin and the wash-out property is remarkably lowered.

On the other hand, there are gel cleansing gels and cream-type cleansing creams that are difficult to dripping and easy to apply. Cleansing gel is an oil thickener dispersed with an acrylic thickener, water-soluble polysaccharide, agar, cellulose thickener or the like. By such a method, a method for preventing dripping from the hand and face during application and facilitating the application is proposed. (Patent Documents 3 and 4)

However, cleansing gels using such polymer thickeners are difficult to obtain a high cleansing effect because oils that exhibit a cleansing effect cannot directly contact oily dirt such as makeup. In addition, there is a problem that it is uncomfortable due to the sliminess on the skin when rinsed with water.

About cleansing cream, it is made to become viscous by making it into an O / W type emulsified state to prevent dripping from the hands and face at the time of application. Therefore, in order for oily dirt such as makeup to dissolve in the oil having a cleansing effect, the oil must be released by breaking the emulsification by a method such as evaporation of water in the composition after coating, It took time to get used to it, and it was difficult to quickly remove makeup. In addition, since the viscosity is high, there is a problem that it is difficult to remove dirt on pores and skin grooves on the skin.

In addition, as a detergent composition having an excellent effect of removing horn plugs and having a good skin feel after washing, the component (A) nonionic surfactant, (B) oil agent, and (C) a carbon number of 2 or more and 6 or less. And a compound having 1 or 2 hydroxyl groups, (E) a water-soluble polymer containing component (D) (meth) acrylic acid as a constituent unit of monomer in the composition of water, or acryloylmethyltaurate / vinylpyrrolidone copolymer There is a cleaning composition of an O / W emulsion obtained by combining the coalescence. The characteristic of this detergent composition is that it changes in the order of three areas: O / W type emulsion area, isotropic one-liquid phase (bicontinuous structure) area, and oil phase area as moisture decreases. is there. By washing with these three phases, the effect of floating and dissolving the square plug, which is a hard solid stain formed in the pores, is excellent, and the effect of removing the square plug is enhanced. However, immediately after application of this composition, the outer layer is water-based, so it takes time until the makeup and oily dirt become familiar, and it is still impossible to quickly remove the makeup.

In this way, although various types of cleansing cosmetics have been proposed in the past, cleansing cosmetics that can be applied to the skin without sagging, quickly remove the makeup from the skin, and can be washed cleanly have not yet been obtained. The development was desired.

JP 2004-217640 A JP 2010-001231 A JP-A-62-135406 JP-A-9-110638 JP 2011-12252 A

The present invention has been made in view of the above-mentioned problems of the prior art, and removes makeup from the skin promptly, and does not fall off from the hand or sag on the face during application, and is easy to apply to the skin. It is an object of the present invention to provide a cleansing cosmetic having a bicontinuous structure that can be refreshed by being washed away.

As a result of intensive studies by the present inventors, a water-soluble polymer and water containing volatile silicone oil, divalent glycol, polyoxyethylene glyceryl isostearate and alkyl-modified (meth) acrylic acid as constituent units of monomers. It has been found that a composition containing can be thickened while maintaining a bicontinuous structure. That is, the present inventors have found that the cleansing cosmetic of the present invention can solve all of the above problems, and have completed the present invention.
Further, it can be mixed with a propellant and used as an aerosol type cleansing cosmetic. By taking these forms, it is possible to make cleansing cosmetics with better foam quality while maintaining the bicontinuous structure when used, or those sprayed into a transparent gel shape over time It becomes possible to make various aerosol products by changing to foam or spraying in the form of mist.
The bicontinuous structure here is a state in which both the aqueous phase and the oil phase are solubilized. Both of these are solubilized, and each of the aqueous phase and the oil phase becomes a continuous phase, and the optically isotropic transparent or translucent isotropic one-liquid phase is called a bicontinuous structure. The detergent composition having a bicontinuous structure in which both the water phase and the oil phase are solubilized has high wettability, the oil component and the water component are familiar with the skin, and the agent reaches the fine parts. Thereby, it is possible to cause the cleaning component to act deeper in the pores after the surface layer is removed. As a result, it is possible to obtain a high cleaning performance and a clean wash.

That is, the present invention
(1) volatile silicone oil,
(2) monovalent or divalent alcohols having 6 or less carbon atoms,
(3) Branched fatty acid polyoxyethylene glyceryl (4) Water-soluble polymer (5) water containing alkyl-modified (meth) acrylic acid as a monomer unit
A cleansing cosmetic characterized by having a bicontinuous structure.

The cleansing cosmetic composition according to the present invention is easy to apply to the skin without sagging from the hand during use or sagging on the face. Moreover, it can be refreshed by washing it clean. In addition, the cleansing cosmetic of the present invention has a bicontinuous structure and thus has a high detergency, and since the appearance is transparent or translucent, the makeup-removing effect can be emphasized. In addition, it is excellent in terms of function and safety, such as being hard to see due to its viscosity.

The volatile silicone oil used in the cleansing cosmetic according to the present invention can be appropriately selected from those conventionally used in cosmetics and the like.

Examples of the volatile silicone oil include hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, etc., which are low molecular siloxane chain silicone oils (chain polysiloxane or chain methylsiloxane). Similarly, hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, etc., which are low molecular weight siloxane cyclic silicone oils (cyclic polysiloxane or cyclic methylpolysiloxane). In addition, caprylyl methicone of an alkyl-modified silicone in which a linear alkyl group is added to Si at the central position of a linear trimer (trisiloxane) may be used.
Examples of commercially available products are SH245 (decamethylcyclopentasiloxane), DC246 (dodecamethylcyclohexasiloxane), FZ-3196, and SS-3408 (caprylylmethicone) manufactured by Toray Dow Corning. There are KF-96A-1cs (octamethyltrisiloxane), KF-96A-1.5cs (decamethyltetrasiloxane), KF995 (decamethylcyclopentasiloxane), etc. manufactured by Shin-Etsu Chemical Co., Ltd.

Although not limited, decamethylcyclopentasiloxane and octamethylcyclotetrasiloxane are particularly preferred from the viewpoint of make-up cleansing power among silicone oils.
In the present invention, one kind of volatile silicone oil as described above may be used, or two or more kinds may be used.

The compounding quantity of the volatile silicone oil in the cleansing cosmetic of this invention is 1-20 mass%, Preferably it is 2-10 mass%. When the blending amount is less than 1% by mass, the make-up cleansing power is not sufficient. When the blending amount exceeds 20% by mass, the oily feeling becomes strong and unpleasant when blending, and the rinse-off feeling is not good. .

The monovalent or divalent alcohol having 6 or less carbon atoms in the cleansing cosmetic according to the present invention is not particularly limited. For example, ethanol, isopropyl alcohol, 1,3-butylene glycol, 1,2-pentylene glycol 1, 4-butylene glycol, 2,3-butylene glycol, dipropylene glycol, ethylene glycol and the like.

The monovalent or divalent alcohol having 6 or less carbon atoms in the present invention is considered to play a role of adjusting the viscosity of the composition, imparting mildness to the skin after washing, and stabilizing the composition. .
The blending amount of monovalent or divalent alcohol having 6 or less carbon atoms in the cleansing cosmetic of the present invention is 1 to 20% by mass, preferably 5 to 15% by mass. When the blending amount is less than 1% by mass, the viscosity becomes low and the moisture retention after washing becomes low. If it exceeds 20% by mass, the stability of the composition tends to deteriorate.

The branched fatty acid polyoxyethylene glyceryl used in the cleansing cosmetic according to the present invention is represented by the following structural formula.

Formula 1

As the branched fatty acid group of the branched fatty acid polyoxyethylene glyceryl in the present invention, for example, a 2-ethylhexanoic acid residue, an isopalmitic acid residue, an isostearic acid residue and the like can be preferably exemplified. The acid polyoxyethylene glyceryl is particularly preferable, and at least one of R1, R2, and R3 in the above structural formula is an isostearyl group.

Further, among polyoxyethylene glyceryl isostearates, monoesters are particularly preferable, those having an average degree of polymerization of ethylene oxide in one molecule of 6 to 20, and more preferably 7 to 10. In this case, the HLB value is generally 8 or more. When these are selected, make-up cleansing power and ease of washing are further improved.

Specific examples include polyoxyethylene (8) glyceryl monoisostearate, polyoxyethylene (10) glyceryl monoisostearate, polyoxyethylene (20) glyceryl monoisostearate, and the like. Examples of commercially available products include EMALEX GWIS-108, GWIS-110, GWIS-120 (manufactured by Nippon Emulsion Co., Ltd.), UNIOX GM-81S, GM-10IS, GM-20IS (manufactured by NOF Corporation), Neugen GIS-108. (Daiichi Kogyo Seiyaku Co., Ltd.).
However, it goes without saying that not only the polyisoethylene glyceryl monoisostearate but also polyoxyethylene (20) glyceryl triisostearate can be used. As a commercial item, Neugen GIS-320 (made by Daiichi Kogyo Seiyaku Co., Ltd.) etc. are mentioned.

The blending amount of polyoxyethylene glyceryl isostearate in the cleansing cosmetic of the present invention is 5 to 40% by mass, preferably 10 to 35% by mass. If the blending amount is less than 5% by mass, rinsing at the time of rinsing or make-up cleansing effect is deteriorated, and if it exceeds 40% by mass, irritation to the skin and eyes may be felt.

The water-soluble polymer containing alkyl-modified (meth) acrylic acid as a monomer unit used in the present invention is synthesized using (meth) acrylic acid as a monomer, for example, acrylic acid / alkyl methacrylate copolymer. A cross-linked copolymer of acrylic acid and alkyl (C10-30) methacrylate, and commercially available products such as PEMULEN
TR-1, PEMULEN TR-2, Carbopol ETD2020 (manufactured by Lubrizol) and the like.
The water-soluble polymer containing (meth) acrylic acid that has undergone alkyl modification of component (4) as a constituent unit of the monomer is adjusted to an appropriate viscosity by blending 0.01 to 1% by mass as a pure component in the entire composition. be able to. At that time, it is preferable to neutralize all or part of the units of (meth) acrylic acid using an alkali agent. The alkali agent to be neutralized is not particularly limited as long as it is an alkali agent that can be usually added to cosmetics. For example, potassium hydroxide, sodium hydroxide, aminomethylpropanol, triethanolamine, L-arginine, guanidine carbonate, etc. Can be used. The alkali agents can be used alone or in combination of two or more, and it is preferable to adjust the pH of the system to 5 to 9, particularly 6 to 7.

The water-soluble polymer containing (meth) acrylic acid subjected to the alkyl modification of the present invention as a constituent unit of a monomer can be expected to have a high thickening effect with a small amount. The cleansing cosmetics characterized by having the bicontinuous structure of the present application can obtain a viscosity of 200 mPa · s to 50 Pa · s by the above thickening effect, and can ensure a sufficient viscosity at the time of use. became.
Moreover, due to its poor salt tolerance, it maintains a sufficient viscosity in the state of the product, but when used it becomes smoother when mixed with oily dirt such as make-up, and when it is washed away. It has the merit of being easy to wash off with less sticking to the skin.

The cleansing cosmetic of the present invention contains 15 to 85 mass%, preferably 30 to 70 mass% of water (the component (5)) in addition to the components (1) to (4). When the blending amount of water is less than 15%, it is difficult to obtain a refreshing feel at the time of use and a fresh feeling at the time of application. If the blending amount exceeds 85% by mass, the makeup cleansing power is lowered.

The propellant when the cleansing cosmetic of the present invention is used as an aerosol cosmetic is not particularly limited as long as it is a propellant that can be used for an aerosol of a cosmetic. For example, hydrocarbons such as liquefied petroleum gas (LPG) mainly composed of propane, n-butane, i-butane, etc., ethers such as dimethyl ether, methyl ethyl ether, diethyl ether, carbon dioxide gas, nitrogen gas, oxygen gas Compressed gas such as These propellants may be used alone or in admixture of two or more, and the blending amount thereof varies depending on the state when jetted, but with respect to 30% by mass to 95% by mass of the cosmetic stock solution, The propellant is 70% by mass to 5% by mass. The mixing ratio of the propellant is more preferably 6 to 12% by mass for foaming and 40 to 60% for mist.

In addition to the components (1) to (5) that are essential components, a surfactant may be added to the cleansing cosmetic according to the present invention as long as the effects of the present invention are not impaired. The type of the surfactant used in the present invention is not particularly limited, and can be appropriately selected from an anionic surfactant, a cationic surfactant, an amphoteric surfactant, and a nonionic surfactant.

In the cleansing cosmetic according to the present invention, in addition to the components (1) to (5) that are essential components, other oil agents may be blended within a range not impairing the effects of the present invention. Common makeup cosmetics, such as foundations, lipsticks and mascaras, often contain silicone oils and hydrocarbon oils, and in order to cleanse such makeups, these oily ingredients are used well. It is important to be able to remove these makeups, especially when volatile hydrocarbon oils such as isododecane are added. In addition, volatile components are useful because they provide a refreshing feeling after washing.

Furthermore, in addition to the surfactant, components usually used in cosmetics and pharmaceuticals can be blended within a range that does not impair the effects of the present invention.
Examples of components that can be blended include humectants, powder components, liquid fats and oils, solid fats and oils, waxes, hydrocarbon oils, higher fatty acids, higher alcohols, synthetic ester oils, natural water-soluble polymers, and semi-synthetic water-soluble polymers. , Synthetic water-soluble polymer, thickener, UV absorber, sequestering agent, lower alcohol, polyhydric alcohol, monosaccharide, oligosaccharide, polysaccharide, amino acid, organic amine, polymer emulsion, pH adjuster, oxidation Inhibitors, antioxidant assistants, antiseptics, anti-inflammatory agents, whitening agents, various extracts, activators, blood circulation promoters, antiseborrheic agents, anti-inflammatory agents and the like.

Further, in the present invention, the cleansing cosmetic has an isotropic one-component phase having a bicontinuous structure means that observation of appearance, observation with an optical polarization microscope, dispersion test of aqueous and oil-based pigments, creation of phase diagrams It can be confirmed by measurement of self-diffusion coefficient by NMR, measurement of electric conductivity, fluorescence probe method using a fluorescent dye, observation of an electron microscope (TEM, SEM, etc.) by a frozen cleaving replica method, and the like.

Since the appearance of the bicontinuous structure is transparent, it is possible to distinguish the isotropic one-liquid phase having the bicontinuous structure from other solutions by determining the appearance. It is also possible to confirm that the polarizing plates of the two polarizing plates are isotropic because there is no light transmission when a sample placed in a transparent container is placed between them with the polarization directions orthogonal to each other. . Furthermore, when observing with an optical polarizing microscope, it is confirmed that the polarizing plate is isotropic because there is no light transmission when the angle of the polarizing plate is 90 degrees.

The dispersion test of aqueous and oily pigments is an amphiphilic liquid bicontinuous mixture that mixes with both water and oil by observing that each of the aqueous and oily pigments is dropped into a sample and rapidly infiltrated. The properties of the microemulsion structure can be confirmed and can be distinguished from the liquid crystal phase, D phase or solubilized phase.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto. In addition, unless otherwise indicated, the compounding quantity in this specification shall represent the mass%.
Cleansing cosmetics having the compositions described in the following Examples 1 to 15 (Table 1) and Comparative Examples 1 to 6 (Table 2) were prepared in a conventional manner. Appearance and infiltration of oil-soluble pigments, infiltration of water-soluble pigments To determine whether it is a bicontinuous structure, gel, or O / W emulsification. Thereafter, the viscosity, ease of application of each cleansing cosmetic, make-up cleansing power, ease of washing, pH and stability were evaluated. An evaluation result is combined with Tables 1-2, and is shown.

Each item was evaluated according to the following evaluation criteria.
<Appearance turbidity test>
The determination was made by visual observation in a quartz cell having a thickness of 1 cm. A black and white striped paper with a width of 5 mm was placed on the opposite side of the quartz cell, and a determination was made according to how much it could be distinguished.
Transparent: Black and white stripes can be clearly identified through the quartz cell.
Cloudiness: Black and white stripes cannot be distinguished at all.
Translucent: A striped pattern can be confirmed to some extent.

<Dispersion test of aqueous and oily pigments>
A liquid prepared by dissolving 0.1 g of tetrachlorotetrabromofluorescein used as an oil-soluble dye in 99.9 g of octyldodecanol was prepared as a staining solution. When the sample was spread in a circle of about 100 yen on a plastic plate, a staining solution was dropped to confirm whether infiltration was observed.
A 0.1% aqueous solution was prepared using brilliant blue FCF as the water-soluble dye, and confirmation was performed in the same manner as described above.
The confirmation of the bicontinuous structure was confirmed by the results of both the confirmation of transparency by the appearance turbidity test and the dispersion test of aqueous and oily pigments.
The bi-continuous structure is judged to be BC (bi-continuous structure) when the appearance is transparent or translucent and both oil-soluble and water-soluble dyes are infiltrated, and the appearance is cloudy. G (gel) when both oil-soluble pigment and water-soluble pigment are infiltrated, O / W (when only water-soluble pigment is infiltrated with white appearance and no oil-soluble pigment infiltration) O / W emulsification).

<Viscosity>
About the viscosity of the cleansing cosmetic of each Example and a comparative example, the viscosity value when it measured using the Brookfield type | mold viscosity meter was entered.

<Ease of application>
It was confirmed that it did not sag when applied to the face.

<Familiarity with makeup when cleansing>
After applying when removing the makeup, it was spread and blended into the makeup. At this time, it was mixed with the makeup within 30 seconds, and the blending was marked with ○, and the blending with the makeup was marked with ×.

<Make-up cleansing power>
About the make cleansing power of each Example and a comparative example, the actual use test was implemented by 10 expert panelists. As a makeup to be dropped, a commercially available liquid foundation that is not easily dropped was used. The evaluation criteria are as follows, and the evaluation points were averaged.
5 points: It has fallen enough.
4 points: Fallen.
3 points: Normal.
2 points: not fallen 1 point: not fallen

<Ease of washing>
The makeup was washed using the cleansing cosmetics of each Example and Comparative Example, and a refreshing feeling after rinsing with water was subjected to an actual use test by 10 professional panelists. The evaluation criteria are as follows, and the evaluation points were averaged.
5 points: A refreshing feeling can be obtained immediately 4 points: A refreshing feeling can be obtained a little earlier 3 points: Normal 2 points: It takes a little time to get a refreshing feeling 1 point: A refreshing feeling cannot be obtained

<PH>
Measurement was performed using a pH meter.

<Stability>
A product that was stored at 50 ° C. for 1 month and had no change in properties was judged to be stable.

As shown in Table 1 above, the composition having a bicontinuous structure of the present invention was excellent in ease of application and cleansing power, and was easy to wash away. Moreover, the viscosity can be easily adjusted by changing the blending amount of the water-soluble polymer containing alkyl-modified (meth) acrylic acid as a constituent unit of the monomer. Also in the example, about 300 mPa.s. s to about 45 Pa.s. It has a viscosity of up to s. That is, it is a highly versatile technique that can provide a bulk corresponding to various containers from a pump container that requires a relatively low-viscosity bulk to a tube container in which a relatively high-viscosity bulk is suitable.

As shown in Table 2 above, Comparative Example 1 had a bicontinuous structure, so cleansing power and washing were good, but because of its low viscosity, it fell off from the place where it was applied and was poor in usability. Comparative Example 2 was a composition having a good viscosity for use, but because it was an O / W emulsion, it did not blend well with oily stains such as makeup, and it took time until the stains floated. In the case of Comparative Examples 3 and 4, Comparative Example 3 was thickened with a carboxyvinyl polymer which is the same acrylic acid thickener. In Comparative Example 4, the volatile silicone oil component is changed to non-volatile dimethicone 20CS. The composition of Comparative Example 3.4 was not a bicontinuous structure but an O / W emulsion. Moreover, it is stabilized by O / W emulsification, and is very unsuitable as a cleansing composition because it is very unfit for oily soils such as makeup. Moreover, thermal stability was weak and it separated at 50 degreeC for a short time.
In the case of Comparative Examples 5 and 6, in Comparative Example 5, glycerin, which is a trivalent alcohol, is used. Comparative Example 6 is a three-component gel containing no surfactant, surfactant, polyhydric alcohol, and water. These compositions of Comparative Examples 5 and 6 had high cleansing power and good washing off. However, in the example having a transparent bicontinuous structure, it was well understood that the dirt was familiar and the dirt floated off the skin, but the comparative example was cloudy and was difficult to understand. When actually used, the degree of satisfaction was low compared to the examples.

Using Examples 1 to 3 in Table 1, aerosol type and pump former type cleansing cosmetics were prepared, and the results of evaluation according to the above criteria are shown in Table 3.
