Description

The present invention relates to a physical property stabilizer capable of stabilizing the physical properties of an aqueous cosmetic composition over time without causing a change in the feeling of use.

BACKGROUND ART Aqueous cosmetics having an aqueous phase as a continuous phase are widely used as cosmetics because they are well familiar to the skin and have excellent usability. On the other hand, there is a problem that the emulsification tends to become unstable because the continuous phase is the aqueous phase. In particular, low-viscosity cosmetics such as emulsions and lotions are prone to problems such that the emulsification breaks down over time and the oil phase and the aqueous phase are separated, and the dispersant and emulsion float or settle.

Therefore, a method of stabilizing by adding a water-soluble polymer to the aqueous phase and increasing the viscosity has been investigated. Among these, (Patent Document 1) to (Patent Document 3) are mentioned as a study of using xanthan gum.

In (Patent Document 1), one or two kinds selected from xanthan gum 0.5 to 2.0% by weight as an A component and polyhydric alcohol or a polyhydric alcohol-containing plant extract extracted with a polyhydric alcohol as a B component. Disclosed is an emulsified skin external preparation containing the above components and containing the component B in an amount of 3 times or more the weight of the component A.
(Patent Document 2) discloses a cosmetic composition containing xanthan gum represented by a specific structural formula and having an apparent weight average molecular weight of 16 million or more.
In (Patent Document 3), 0.7 to 1.5% by weight of xanthan gum as an A component, one or more oily components that are liquid at room temperature as a B component, and a semisolid oily component at room temperature as a C component. One or two or more kinds and one or more kinds of oily components which are solid at room temperature as the D component, and the content of all the oily components B to D with respect to the A component is 7 times or more by weight. There is disclosed an oil-in-water emulsion cosmetic composition.
Further, as a study of using carrageenan, (Patent Document 4) is cited, and a cosmetic additive characterized by using carrageenan fine powder having a maximum particle size of 40 μm or less and an average particle size of 15 μm or less as an active ingredient. Agents are disclosed.

However, the methods described in any of the documents have a certain effect on stabilization such as emulsification, but the feeling of use becomes different, and there is a problem that stickiness comes out particularly when xanthan gum is used. ..
On the other hand, synthetic polymers such as carboxyvinyl polymers are also used, but in addition to changing the feeling of use, in recent years, naturally derived components are often required, and their applications may be limited. ..
Further, if the cosmetic containing the above-mentioned thickener is stored under high temperature in a place where temperature control is not sufficient, the effect as the thickener is lost.
As described above, although there is a strong demand for a naturally-derived component that can stabilize the emulsification without changing the feeling of use and the texture, there is currently no suitable option.

Therefore, an object of the present invention is to provide a naturally-occurring physical property stabilizer capable of stabilizing the physical properties of an aqueous cosmetic composition with time without changing the feeling of use.

The inventors of the present invention have made various studies to solve the above-mentioned problems. As a result, by containing a small amount of β-1,3-1,6-glucan, the above-mentioned problems can be solved, especially under a high temperature condition of more than 40°C. However, it was found that the physical properties can be stabilized. This is noteworthy considering that many thickeners used in cosmetic applications rapidly lose their effect under high temperature conditions such as above 40°C.
That is, the present invention is a physical property stabilizer for aqueous cosmetics, which comprises β-1,3-1,6-glucan as an active ingredient.

According to the present invention, the physical properties of an aqueous cosmetic composition can be stabilized over time without causing a change in the feeling of use.

The physical property stabilizer for aqueous cosmetics of the present invention contains β-1,3-1,6-glucan as an active ingredient.
β-1,3-1,6-glucan is β-glucose in which glucose is linked by β-1,3-glycoside bond and β-1,6-glycoside bond, and (1) the main chain is β- 1,3-glycoside bond having a branch of β-1,6-glycoside bond, (2) main chain consisting of β-1,3-glycoside bond and β-1,6-glycoside bond Etc. are known. As the β-1,3-1,6-glucan used in the present invention, those partially having a bond such as β-1,4-glycoside bond can also be used, but β-1,3-glycoside The content of bonds and glucoside bonds other than β-1,6-glycoside bonds must be 10 mol% or less based on the total of β-1,3-glycoside bonds and β-1,6-glycoside bonds.

In the physical property stabilizer for aqueous cosmetics of the present invention, any β-1,3-1,6-glucan can be used as β-1,3-1,6-glucan, but the solubility is Β-1,3-1,6-glucan represented by the following general formula (1) is preferable because it is good:

In the general formula (1), a represents a number of at least 20 and b represents a number of at least 1. However, the total number of a and b is a number which makes the mass average molecular weight of the β-1,3-1,6-glucan represented by the general formula (1) 3,000 to 5,000,000. When the mass average molecular weight of β-1,3-1,6-glucan represented by the general formula (1) is less than 3000 or more than 5 million, the physical properties are stable without changing the feeling of use of the cosmetic. The effect, especially the emulsion stability may become insufficient. The mass average molecular weight of β-1,3-1,6-glucan represented by the general formula (1) is preferably 5,000 to 3,000,000, more preferably 7,000 to 1,000,000, and most preferably 10,000 to 500,000. In the present invention, the mass average molecular weight of β-1,3-1,6-glucan is the pullulan conversion in the case of performing gel permeation chromatography (also referred to as GPC) analysis using water as a solvent. The mass average molecular weight. In addition, "mass average molecular weight" may be called "weight average molecular weight."

The method for measuring the mass average molecular weight is not particularly limited, as an example, using several types of pullulan known molecular weight (concentration is arbitrary), calibration curve by the differential refraction detector (holding time x axis, Create a molecular weight on the y-axis. Next, it is common to measure the sample (the concentration is arbitrary) and calculate the relative molecular weight (molecular weight in terms of pullulan) from the retention time using the above calibration curve.
However, due to the difference in structure between pullulan and β-1,3-1,6-glucan, the molecular size is different even with the same molecular weight (the same number of glucose units), so only relative values can be obtained by gel shaking chromatography, which is a molecular sieve. However, it is possible to calculate the intrinsic molecular weight that is close to the absolute value by making a correction. Examples of the correction include a method of measuring the concentration of the sample and a method of measuring and calculating three points of differential pressure viscosity, differential refraction and light scattering. Specifically, first, the apparatus constant k is obtained using a pullulan standard solution whose concentration, viscosity, and refractive index are known.

Next, the drug substance whose β-1,3-1,6-glucan concentration was measured by the phenol-sulfuric acid method was precisely measured to prepare an aqueous solution of known concentration, which was used as a sample. Then, the molecular weight is calculated from the values measured by the differential pressure viscosity detector, the suggested refraction detector, and the light scattering detector.

In the general formula (1), the ratio of b to a is preferably 0.2 to 1, more preferably 0.5 to 0.95, and 0.6 to 0.9. Is most preferred. The unit having the number of repeats a and the unit having the number of repeats b may be bonded randomly or in a block.

The β-1,3-1,6-glucan represented by the general formula (1) can be obtained by a known method, for example, yeast, lactic acid bacterium, natto bacterium, acetic acid bacterium, koji mold, algae such as chlorella and spirulina, filamentous fungi, etc. It can be obtained by extraction from the cell wall or the product of. Among them, β-1,3-1,6-glucan having a high moisturizing effect on the skin can be extracted from black yeast (Aureobasidium u pullulans). There is no particular limitation on the method for extracting β-1,3-1,6-glucan, and a known method may be used.

Further, when the extracted β-1,3-1,6-glucan is concentrated, it is not particularly limited as long as it is a method for removing water or pulverizing. For example, spray drying, freeze drying, reduced pressure drying, heat drying, precipitation collection with a solvent, and the like can be mentioned, and these can be appropriately combined.

The physical property stabilizer for aqueous cosmetics of the present invention preferably contains the β-1,3-1,6-glucan as a solid content of 0.1% by mass or more based on the total amount of the physical property stabilizer. The content is preferably 0.5% by mass or more, and more preferably 0.7% by mass or more. If it is less than 0.1% by mass, the amount of the physical property stabilizer for aqueous cosmetics necessary for obtaining an effective effect may be too large.

In the physical property stabilizer for aqueous cosmetics of the present invention, when the β-1,3-1,6-glucan is in the form of an aqueous solution, the concentration of the β-1,3-1,6-glucan is 2% by mass. In the above case, the solution is not completely dissolved and precipitation is likely to occur.

Among these polyhydric alcohols, propylene glycol, dipropylene glycol, 1,3-butanediol, and glycerin are preferable because of excellent dispersion stability of β-1,3-1,6-glucan, and 1,3- Butanediol is more preferred.

When the polyhydric alcohol is contained in an amount of 50 to 90% by mass as described above, the content of water in the physical property stabilizer of the present invention is preferably 5 to 27% by mass. When the content of water is less than 5% by mass, the dispersion stability of β-1,3-1,6-glucan may decrease, and when it is more than 27% by mass, β-1,3 The content of 3-1 and 6-glucan becomes relatively small, and even if fluidity is observed immediately after blending, it may become gelled with time and the fluidity may decrease.

Since the physical property stabilizer of the present invention has a large effect of stabilizing the emulsification even in an aqueous solution having a low viscosity, it can be particularly suitably used as an “emulsion stabilizer”.
Further, the physical property stabilizer of the present invention has a large effect of suppressing sedimentation and stabilizing dispersion when it contains a fine particle component such as titanium oxide or zinc oxide which is not soluble in water even if it is a low-viscosity aqueous liquid. Therefore, it can be particularly preferably used as a “dispersion stabilizer”.
