Description

  The present invention relates to cosmetics, in particular, a detergent composition, and in particular, to an improvement in cleaning effect and an improvement in use feeling.

  Conventionally, cleansing cosmetics and makeup-removing cosmetics intended to remove skin and hair stains and makeup cosmetics have been formulated with an oil component to dissolve and disperse dirt and makeup. There are O / W and W / O emulsified types that are emulsified, oil types in which several kinds of oils are mixed, and the like. Recently, there is also an aqueous type in which a large amount of a surfactant having a moderate HLB is blended without oil.

  However, in the case of O / W emulsified makeup remover cosmetics, it can be used with wet hands, and a fresh feeling of use can be obtained. On the other hand, since it is difficult to contain a large amount of oil, there is a problem that the detergency is weak. there were. In the case of W / O emulsification type or oil type make-up removal, there are few problems with familiarity and removal with makeup, but there are significant problems in use feeling such as leaving the oily after tissue off or face washing. Further, in the case of the aqueous type, there is a problem that the washing power is not sufficient although there is no oiliness and a refreshing feeling can be obtained.

In order to solve the above-mentioned problem of make-up removal, in recent years, a specific nonionic surfactant, a low-viscosity oil, a water-soluble solvent and water are used in combination, whereby the aqueous phase and the oil phase become a continuous phase. A cleansing composition having such a bicontinuous structure has been developed (see, for example, Patent Documents 1 and 2). However, since the composition has the above-mentioned continuous phase, it has a very high detergency. However, since the composition is a low-viscosity liquid, problems such as sagging during make-up removal occur.
In addition, a gel-type cleansing composition containing a hydrophilic nonionic active agent, an anionic surfactant, a water-soluble compound having a hydroxyl group, liquid oil, and water in a specific blending amount has been developed (for example, Patent Documents). 3). However, since the above composition contains a large amount of oil, there are problems such as an oil film feeling and a sticky feeling after washing or after washing, and a refreshing feeling during use is not sufficient.

  In addition, it contains a nonionic surfactant, a water-soluble substance having a hydroxyl group, silicone oil, and water in order to improve the familiarity with make-up removal, and has a liquid crystal phase and / or an isotropic surfactant continuous phase. Cosmetics have been developed (see, for example, Patent Document 4). However, although the above-mentioned cosmetics are relatively less oily on the skin during massage and after washing off, the cleansing action is not sufficient, and it is easy to adapt to the spread and dirt on the skin. Is not satisfactory. Moreover, the compatibility with water was poor, and the above composition and dirt were not easily removed due to water.

In addition, it is preferable that the compounding quantity of an oil-based component is the range of 20-80 mass% with respect to the composition whole quantity, More preferably, it is 40-80 mass%. If the blending amount of the oil component is less than 20% by mass, a sufficient cleaning effect may not be obtained, and the spread during use may not be good, and if it exceeds 90% by mass, the stability may be lacking. In particular, the oil content (B ₁ ) taken into the micelles in the discontinuous micelle cubic liquid crystal phase is more preferably 5 to 30% by mass in terms of detergency and ease of spreading.

  The blending amount of (C) water used in the present invention is not particularly limited, but depending on the types and blending amounts of (A) and (B) used when producing cosmetics, It is necessary to adjust the blending amount as appropriate so that the continuous micelle cubic liquid crystal is formed.

Further, when the component (D) is added to the continuous phase comprising the aqueous component (C), the refraction of the discontinuous micelle cubic liquid crystal phase (ie, the outer phase) in which the cubic crystals of spherical micelles are formed in the continuous phase. The rate increases, and the difference in refractive index from the oil phase (B ₂ ) composed of the oil component (B) decreases.

In the cosmetic of the present invention, it is necessary that the external phase of the emulsified composition is a discontinuous micelle cubic liquid crystal phase.
That is, the association state formed by the mixture of surfactant / oil component / water is roughly divided into microemulsions and liquid crystals. Further, when excessive water or oil is added thereto, a water-in-oil emulsion composition or an oil-in-water emulsion composition may be formed.

In addition, as a microemulsion,
[1] Micelle aqueous solution (L ₁ )
[2] Reverse micelle oil solution (L ₂ )
[3] Bicontinuous microemulsion (L ₃ )
Are well known.
Since the aqueous micelle solution has a low surfactant and oil concentration, it is inferior in its cleaning effect. Further, the reverse micelle oil solution has a low viscosity and is slightly inferior in washing with water due to its high lipophilicity. The bicontinuous microemulsion has a continuous structure of water and oil, and thus has a very high detergency and washability. However, since the bicontinuous microemulsion is a low-viscosity liquid, it causes problems such as dripping when making off.

  Emulsified compositions are very common, and many cosmetics and the like are classified into this, but most of them are white turbid as represented by creams and emulsions. Oil-in-water emulsion compositions have a large amount of oil content. In many cases, it is difficult to formulate, and when used as a cleaning agent, the cleaning power is weak. On the other hand, when used as a cleaning agent, a water-in-oil emulsified composition is difficult to wash away and cannot provide a refreshing feeling.

The liquid crystal structure is [I] micelle cubic (discontinuous cubic) liquid crystal phase (I ₁ ).
[II] Hexagonal liquid crystal phase (H ₁ )
[III] Bicontinuous cubic liquid crystal (V ₁ )
[IV] Lamella liquid crystal phase (L _α )
[V] Bi-continuous cubic liquid crystal (V ₂ )
[VI] Reversed hexagonal liquid crystal phase (H ₂ )
[VII] Reversed micelle cubic (discontinuous cubic) liquid crystal phase (I ₂ )
Are well known.
Of these, the lamellar liquid crystal phase (L _α ) often has a high surfactant concentration, and irritation to the skin is observed. The reverse hexagonal liquid crystal phase and the reverse micelle cubic liquid crystal phase have high lipophilicity and therefore lack washing properties. Further, the hexagonal liquid crystal phase (H ₁ ) does not spread well during use.

In order to obtain a make-up cleansing base that has excellent washability with water and does not easily drip off during make-up removal and has good spread during use, the present inventors have developed a discontinuous cubic (micelle cubic) liquid crystal phase. Pay attention.
Since the discontinuous micelle cubic liquid crystal has high viscoelasticity due to its structure, it is possible to hold the oil as emulsion particle droplets by adding an oil having a concentration higher than the limit concentration that can be taken into the micelle cubic liquid crystal structure. That is, an oil-in-water emulsion composition in a cubic liquid crystal can be obtained. This discontinuous micelle cubic liquid crystal is used as an outer phase, and when considering using a cubic liquid crystal oil-in-water emulsified composition in which an additional oil component (B ₂ ) is held as emulsified particles in the inner phase as a cleaning composition, In order to increase the force, it is necessary to contain a large amount of oil. However, since there is a limit to the oil (B ₂ ) that can be stably held as emulsified particles, in order to obtain an emulsified composition containing a larger amount of oil, a large amount of oil (B ₁₎ is also present in the cubic liquid crystal structure that is the outer phase. ) Is desirable. That is, in order to increase the total oil content B (= B ₁ + B ₂ ), it is important to increase not only B ₂ but also B ₁ .
In the discontinuous cubic liquid crystal phase, one of the hydrophobic and hydrophilic regions in the liquid crystal structure has a continuous structure, while the other region has a spherically closed structure. It is what. The micelle cubic liquid crystal phase (I ₁ ) is a discontinuous cubic whose hydrophilic region has a continuous structure, but the hydrophobic region has a closed spherical structure. That is, the surfactant molecules form an aggregate in which the hydrophobic region is inward and the hydrophilic region is outward, and this aggregate is further regularly arranged in three dimensions to form a liquid crystal structure. It is what. However, it has been conventionally considered that this discontinuous micelle cubic liquid crystal is difficult to contain a high concentration of oil.

Therefore, the present inventors have arranged a disconti in which a cubic structure is formed by micelles of alkylethylene oxide type surfactants of medium HLB to slightly high HLB (medium polarity to slightly hydrophilic) in a water (aqueous component) continuous phase. A micellar cubic liquid-crystal-in-oil (O / I ₁ ) type emulsion composition was developed, in which a numerous cubic liquid crystal phase (I ₁ ) was formed, and the liquid crystal phase was an outer phase and an oil content was retained as an inner phase.
FIG. 1 is a diagram showing a discontinuous micelle cubic liquid crystal structure and an oil phase in the micelle cubic liquid crystal. As shown in FIG. 1, in the composition of the present invention, the oil (oil component) is contained in the individual micelles (B ₁ ) and the emulsion particles (B ₂ ) dispersed in the liquid crystal. There are two types. In the present invention, conditions for increasing the solubilization amount of these oil components are specified, and a high detergency and an improved feeling in use are realized.

The micellar cubic liquid crystal middle oil (O / I ₁ ) type emulsion composition formed by the cosmetic of the present invention is preferably formed through an I ₁ phase composition. For example, when the component (B) is gradually added when the components (A) to (C) described above are mixed, I ₁ is formed first, and when the component (B) is further added, excess ( The component B) is dispersed in the liquid crystal and becomes O / I ₁ .
Subsequently, a method for determining the discontinuous micelle cubic liquid crystal phase will be described below.

Sample preparation (1) A surfactant, ion-exchanged water and oil are weighed into a sample tube and stirred with a strong shearing force.
(2) If the sample of (1) is not sufficiently stirred, raise the temperature to around 70 ° C. and stir. After returning to room temperature, the mixture is stirred again.
(3) Centrifugation for a sufficient period of time to remove bubbles.
(4) Whether the obtained sample is a discontinuous micellar cubic liquid crystal phase is determined by “appearance judgment”, “polarization microscope observation and X-ray structural analysis”, “preparation of phase equilibrium diagram”, “electric conduction” Degree measurement "," Measurement of self-diffusion coefficient by NMR "," Electron microscopic observation of replica prepared using freeze fracture method ", and the like. It may be determined by any method.

Determination by appearance In the determination by appearance, the discontinuous micellar cubic liquid crystal phase (I ₁ ) is a transparent to translucent one-phase region and is optically isotropic. Determination of optical anisotropy can be made by holding the sample while combining two polarizing plates with a phase difference of 90 degrees and confirming that there is light transmission.
The micelle cubic liquid crystal oil-in-oil (O / I ₁ ) type emulsion composition is usually opaque, but can be adjusted to a transparency close to the I ₁ phase by adding a polyhydric alcohol and / or sugar.
In such a case, I ₁ and O / I ₁ can be discriminated from the inter-cubic micelle distance d obtained by X-ray structural analysis (SAXS). That is, when changing the oil concentration in the system, the region d values change is I _1, the region does not change is determined to be O / I _1.

Polarization microscope observation and X-ray structure analysis According to the polarization microscope observation and X-ray structure analysis, when an anisotropic band-like pattern is observed and a scattering peak corresponding to the layer interval appears, it is considered to be a lamellar liquid crystal phase. Further, when an anisotropic streak pattern is observed and a sharp scattering peak appears in the hexagonal rod-like micelle interval period, it is considered to be a hexagonal liquid crystal phase. When it is a dark field by polarization microscope observation and a spot with cubic symmetry appears, it is considered as a cubic liquid crystal phase.

Creating a phase equilibrium diagram In creating a phase equilibrium diagram, when creating a three-component phase equilibrium diagram composed of water / oil component / surfactant, the concentration range that the discontinuous micelle cubic liquid crystal phase produces is Although it can be identified by having a feature such as a region adjacent to the hexagonal liquid crystal phase, this feature varies depending on the system (component) to be constructed.

Electrical conductivity measurement In electrical conductivity measurement, liquid crystal phase has characteristic electrical properties due to the fluidity of each phase, continuity of structure, and anisotropy, so conductivity measurement under appropriate conditions It is possible to obtain information about the phase by performing. High electrical conductivity can be confirmed in a water-continuous liquid crystal structure (this applies to discontinuous micelle cubic liquid crystal phases). Therefore, for example, it is possible to discriminate from a bicontinuous cubic liquid crystal phase whose electrical conductivity is about そ の.

Measurement of self-diffusion coefficient by NMR Self-diffusion coefficient measurement by NMR is described by Lindman et al. Colloid Interface Sci. 1981, 83, 569 and the like.

Electron Microscopic Observation of Replicas Prepared Using the Freeze Fracture Method According to the electron microscopic observation of the phase sample prepared using the freeze fracture method, it is possible to obtain an image of a discontinuous micelle cubic liquid crystal phase. According to this image, the hexagonal liquid crystal phase, the lamellar liquid crystal phase, and the aggregate image obtained in other phases can be easily distinguished. This method is described in the literature Colloid polym. Sci. 1994, 272, 604.

  From these, the mass ratio of the component (A) alkylethylene oxide surfactant and the component (C) moisture of the present composition is 20:80 to 70:30, contains an appropriate amount of oil, and is optically isotropic. When a highly transparent viscoelastic body is formed, it can be confirmed that it is a discontinuous micelle cubic liquid crystal phase by using the various methods described above.

Moreover, the cosmetic according to the present invention can be widely used for various applications as a detergent composition, skin care cosmetic, hair cosmetic, and makeup cosmetic. Furthermore, as a cleaning composition, it can be widely used for various uses conventionally applied. For example, shampoo, body cleansing agent, facial cleanser, wet tissue (for washing), wet tissue (for face washing), makeup remover (for mascara, eye shadow, foundation) and the like can be mentioned. Examples of skin care cosmetics include massage creams, massage gels, body creams, body gels, and packs.

Production method: (A) POE (10) Isostearyl ether and component (C) water are mixed and dissolved by heating to about 70 ° C., and then the oily component of component (B) is gradually added while stirring. Stir and mix. Then, the external appearance of the prepared composition is confirmed.

In the example shown in Table 1 and FIG. 2, when the ratio of (A) alkylethylene oxide type surfactant and (C) moisture is in the X region, adding an oil component (18-32%) will The continuous micelle cubic liquid crystal phase (I ₁ ) region is reached. That is, in the case of the component structure of FIG. 2, it is understood that the range of POE (10) isostearyl ether: water = 28: 72 to 38:62 is the X region.
Incidentally, the addition of this oily component reaches I ₁ region (A) and component (C) weight ratio of (ie, X region) will vary depending on the configuration of the surfactants and other ingredients used. As a result of further investigation by the present inventors, the mass ratio (A) :( C) was 20:80 to 70:30, preferably 20:80 to 45:55.

From the results shown in Table 1, the cosmetic of Example 1 containing a surfactant having an HLB of 11 and containing 50% by mass of oil has a discontinuous cubic liquid crystal phase as an outer phase, and is not easily washed off. It was found that it was highly effective and could be washed away and had high stability. However, in Comparative Example 1 in which the outer phase is a hexagonal liquid crystal phase, the spread during use was not good, and there was a problem in stability. In Comparative Example 2 in which the outer phase is a lamellar liquid crystal phase, the surfactant content was high, skin irritation was slightly observed, the spread during use was not good, and the stability was low.
Next, the present inventors examined the relationship of the optimal HLB of (A) alkylethylene oxide type surfactant.

Manufacturing method: After mixing various (A) alkylethylene oxide type surfactants and component (C) water and heating to about 70 ° C. to dissolve, gradually add the oil component of component (B) while stirring. Stir and mix. Then, the external appearance of the adjusted composition is confirmed.

From the results of Table 2, the cosmetics of Production Examples 1-1 to 1-4 containing an alkylethylene oxide surfactant having an HLB of 8 to 13 and isododecane of 50% by mass have a discontinuous cubic liquid crystal phase as the outer phase. The micelle cubic liquid crystal oil-in-oil (O / I ₁ ) type emulsified composition was found to be an excellent cosmetic that hardly drips off, has a high cleaning effect, and can be washed away. In particular, in Production Examples 1-1 to 1-3 using a surfactant having an HLB of 8 to 10, an oil content of 5 to 30% by mass can be retained inside the micelle (B1), and the HLB is 13 alkylethylene oxide. As compared with the case of Production Example 1-4 using a type surfactant, a marked improvement in cleaning effect was observed.
On the other hand, in Production Example 1-5 containing a surfactant having an HLB of 14, an emulsion whose outer phase is a discontinuous micelle cubic liquid crystal phase is obtained, but the amount of oil (B1) that can be retained in the micelle is small. Therefore, the spread was not good and some problems were observed in the stability over time. In Production Example 1-6 containing a surfactant having an HLB of 5, a discontinuous micelle cubic liquid crystal phase is not formed, and sufficient cleaning effect, usability, ease of washing, and stability cannot be obtained. It was.
Therefore, in the present invention, the HLB of the (A) alkylethylene oxide surfactant is 8 to 13, more preferably 8 to 10.
Next, the present inventors examined the blending amount of the oil component (B) that can be blended in the cosmetic of the present invention.

Production method: (A) Alkylethylene oxide surfactant and component (C) water are mixed and dissolved by heating to about 70 ° C., and then the oily component of component (B) is gradually added while stirring. Stirring and mixing were performed to obtain a micellar cubic liquid crystal oil-in-oil (O / I ₁ ) type emulsion composition in which the outer phase is a discontinuous cubic liquid crystal phase.

As shown in Table 3, the cosmetics of Production Examples 2-2 to 2-5 containing 40% by mass or more of oil are less likely to sag, have a high cleaning effect, and can be washed away. Had.
Therefore, in the present invention, the total amount of oil contained in the cosmetic is 20 to 80% by mass, preferably 40 to 80% by mass.

Next, the present inventors evaluated the compositions of Example 2 which is a cosmetic according to the present invention, Comparative Example 3 which is a conventional water-based cleansing gel make-up remover, and Comparative Example 4 which is a conventional cleansing oil, together with its evaluation. It shows in Table 4 and FIG.

  From the above Table 4 and FIG. 3, it was clarified that the cosmetic of the present invention has an extremely high makeup removing effect as compared with the conventional water-based cleansing gel makeup remover (Comparative Example 2). Moreover, it became clear that the cosmetics of this invention were excellent in the rinse-off property, while having the washing | cleaning effect comparable as the conventional cleansing oil (comparative example 4).

Furthermore, the following examination was performed about the blending of (D) polyhydric alcohol.
Each production example (make-up removal) according to the formulation shown in Table 5 below was subjected to an actual use test and evaluated according to the above evaluation criteria and the following evaluation criteria (base transparency). The results are shown in Table 5.
<Transparency of composition>
The visible light transmittance (optical path length 0.5 cm) at a wavelength of 600 nm was measured with a spectrophotometer (Hitachi U3510), and the transparency of the composition of each production example was evaluated according to the following criteria.
A: The transmittance is 80% or more.
B: The transmittance is 60% or more and less than 80%.
C: The transmittance is 30% or more and less than 60%.
D: The transmittance is 10% or more and less than 30%.
E: The transmittance is less than 10%.

Production method: Component (A), Component (C), and Component (D) are mixed and dissolved by heating to about 70 ° C., then component (B) is gradually added with stirring, and stirred and mixed. A micellar cubic liquid-crystal oil-in-oil (O / I ₁ ) type emulsion composition having an external phase as a discontinuous cubic liquid crystal phase was obtained.

As shown in Table 5, as the glycerin, which is a polyhydric alcohol, is added to the composition, the transparency of the composition increases. In Production Example 3-1, which does not contain a polyhydric alcohol, The appearance was transparent gel in Production Examples 3-5 and 3-6.
Further, in Production Examples 3-3 to 3-6 in which the ratio of polyhydric alcohol to water was 20% or more, the ease of spreading was improved as compared with other examples.
From the above, in the present invention, by adding a polyhydric alcohol as the component (D), the appearance (transparency) of the composition can be changed while maintaining the cleaning effect and the feeling of use. Moreover, although the external appearance can be changed sufficiently by setting the blending amount of the polyhydric alcohol to (C) :( D) = 90: 10 to 60:40, in particular, (C) :( D ) = 80: 20 to 50:50, a more pleasing cosmetic can be obtained.

Subsequently, an actual use test was conducted for each of the production examples (make-up removal) according to the formulation shown in Table 6 below, and each was evaluated according to the above evaluation criteria. The results are shown in Table 6.
Production method: Component (A), Component (C), and Component (D) are mixed and dissolved by heating to about 70 ° C., then component (B) is gradually added with stirring, and stirred and mixed. A micellar cubic liquid-crystal oil-in-oil (O / I ₁ ) type emulsion composition having an external phase as a discontinuous cubic liquid crystal phase was obtained.

As shown in Table 6, regardless of the type, the transparency of the composition containing the polyhydric alcohol increased and became a transparent to translucent gel. Moreover, the improvement of the ease of spreading by addition was recognized in all the examples which mix | blended the polyhydric alcohol. On the other hand, in Production Example 4-1, in which a monohydric alcohol (ethanol) was blended, the change in transparency was hardly observed with the same amount of addition and the feel in use was not changed as compared with the other production examples.
From the above, in the present invention, polyhydric alcohols, particularly 1,3-butylene glycol, dipropylene glycol, glycerin, polyethylene glycol, and sorbitol can be suitably blended.
