Description

The present invention relates to a physical property stabilizer that can stabilize the physical properties of aqueous cosmetics over time without causing any change in the feeling of use.

BACKGROUND ART Aqueous cosmetics that have an aqueous phase as a continuous phase are used in a wide range of applications as cosmetics because they blend well with the skin and have an excellent feel when used. On the other hand, since the continuous phase is an aqueous phase, there is a problem that emulsification tends to become unstable. In particular, low-viscosity cosmetics such as emulsions and lotions tend to break down over time, causing problems such as oil and water phases separating, and dispersants and emulsions floating or settling.

Therefore, methods have been studied to stabilize the aqueous phase by incorporating a water-soluble polymer into the aqueous phase to increase its viscosity. Among these, studies on the use of xanthan gum include (Patent Document 1) to (Patent Document 3).

(Patent Document 1) includes 0.5 to 2.0% by weight of xanthan gum as the A component, and one or two types selected from polyhydric alcohols or polyhydric alcohol-containing plant extracts extracted with polyhydric alcohols as the B component. An emulsified skin preparation for external use is disclosed, which contains the above ingredients and is characterized in that the content of component B is three times or more by weight relative to component A.
(Patent Document 2) discloses a cosmetic material characterized by containing xanthan gum represented by a specific structural formula and having an apparent weight average molecular weight of 16 million or more.
(Patent Document 3) describes 0.7 to 1.5% by weight of xanthan gum as component A, one or more oily components that are liquid at room temperature as component B, and oily components that are semi-solid at room temperature as component C. It is characterized by containing one or more oily components that are solid at room temperature as component D and one or more oily components that are solid at room temperature, and the content of all oily components B to D relative to component A is 7 times or more by weight. An oil-in-water emulsion cosmetic is disclosed.
Further, studies on the use of carrageenan include (Patent Document 4), which is an additive for cosmetics characterized in that the active ingredient is carrageenan fine powder with a maximum particle size of 40 μm or less and an average particle size of 15 μm or less. Agents are disclosed.

However, although the methods described in both documents have a certain effect on stabilizing emulsification, etc., the feeling of use is different, and there is a problem that the method becomes sticky, especially when xanthan gum is used. .
On the other hand, synthetic polymers such as carboxyvinyl polymers are also used, but in addition to causing changes in the feel of use, in recent years there has been a growing demand for naturally derived ingredients, which may limit their applications. .
Furthermore, if a cosmetic containing the above-mentioned thickener is stored at a high temperature in a place where temperature control is insufficient, the effect as a thickener will be lost.
As described above, although there is a strong demand for naturally derived ingredients that can stabilize emulsification without changing the feel or texture of the product, there is currently no suitable option.

Japanese Patent Application Publication No. 11-79932 Japanese Patent Application Publication No. 11-236310 Japanese Patent Application Publication No. 2003-104828 Japanese Unexamined Patent Publication No. 7-101823

Therefore, an object of the present invention is to provide a naturally derived physical property stabilizer that can stabilize the physical properties of aqueous cosmetics over time without causing any change in the feeling of use.

The present inventors have conducted various studies to solve the above problems, and have found that the above problems can be solved by containing a small amount of β-1,3-1,6-glucan, especially under high temperature conditions exceeding 40°C. However, we found that the physical properties can be stabilized. This is noteworthy considering that many thickeners used in cosmetic applications rapidly lose their effectiveness at high temperatures above 40°C.
That is, the present invention is a physical stabilizer for aqueous cosmetics containing β-1,3-1,6-glucan as an active ingredient.

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

The physical 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 refers to β-glucose in which glucose is linked by β-1,3-glycosidic bonds and β-1,6-glycosidic bonds, and (1) the main chain is β- 1,3-glycosidic bonds with branches of β-1,6-glycosidic bonds; (2) those whose main chain consists of β-1,3-glycosidic bonds and β-1,6-glycosidic bonds; etc. are known. Note that as the β-1,3-1,6-glucan used in the present invention, those having a bond such as a β-1,4-glycosidic bond can be used in part, but β-1,3-glycoside The content of glycosidic bonds other than bonds and β-1,6-glycosidic bonds must be 10 mol% or less based on the total of β-1,3-glycosidic bonds and β-1,6-glycosidic bonds.

Any β-1,3-1,6-glucan can be used as the β-1,3-1,6-glucan in the physical property stabilizer for aqueous cosmetics of the present invention, but the solubility is Since it has good properties, β-1,3-1,6-glucan represented by the following general formula (1) is preferred:

In the above 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 that makes the mass average molecular weight of β-1,3-1,6-glucan represented by general formula (1) 3,000 to 5,000,000. When the mass average molecular weight of β-1,3-1,6-glucan represented by general formula (1) is less than 3000 or greater than 5 million, the physical properties of the cosmetic can be stabilized without changing the feeling of use. The effect of emulsion, especially emulsion stability, may be insufficient. The mass average molecular weight of β-1,3-1,6-glucan represented by 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 weight average molecular weight of β-1,3-1,6-glucan in terms of pullulan when analyzed by gel permeation chromatography (GPC) using water as a solvent. Mass average molecular weight. Note that "mass average molecular weight" may also be referred to as "weight average molecular weight."

The method for measuring the mass average molecular weight is not particularly limited, but as an example, several types of pullulan with known molecular weights (concentrations are arbitrary) are used, and a calibration curve (the x-axis is the retention time, Create a y-axis (molecular weight). Next, the sample (at any concentration) is measured, and the relative molecular weight (molecular weight in terms of pullulan) is generally calculated from the retention time using a calibration curve.
However, because pullulan and β-1,3-1,6-glucan have different structures, their molecular sizes are different even though they have the same molecular weight (same number of glucose units), so gel shaking chromatography, which uses a molecular sieve, can only yield relative values. By correcting it, it is possible to calculate an intrinsic molecular weight that approximates the absolute value. Examples of correction include a method of measuring the concentration of the specimen, measuring three points of differential pressure viscosity, differential refraction, and light scattering, and calculating. Specifically, first, the device constant k is determined using a pullulan standard solution whose concentration, viscosity, and refractive index are known.

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

In the above general formula (1), the ratio of b to a is preferably 0.2 to 1, more preferably 0.5 to 0.95, and more preferably 0.6 to 0.9. is most preferred. Note that the units with a repeat number a and the units with a repeat number b may be combined in a random manner or may be combined in a block shape.

β-1,3-1,6-glucan represented by the general formula (1) can be obtained by known methods such as yeast, lactic acid bacteria, natto bacteria, acetic acid bacteria, koji mold, algae such as chlorella and spirulina, filamentous fungi, etc. It can be obtained by extraction from the cell walls and products of. Among them, β-1,3-1,6-glucan, which has a high moisturizing effect on the skin, can be extracted from black yeast (Aureobasidium pullulans). There are no particular restrictions on the method for extracting β-1,3-1,6-glucan, and any known method may be used.

Furthermore, when concentrating the extracted β-1,3-1,6-glucan, there is no particular limitation as long as the method is for removing water or turning it into powder. For example, spray drying, freeze drying, reduced pressure drying, heat drying, precipitation recovery using a solvent, etc. can be used, and these methods can be appropriately combined.

The physical property stabilizer for aqueous cosmetics of the present invention preferably contains 0.1% by mass or more of the β-1,3-1,6-glucan as a solid content based on the total amount of the physical property stabilizer, The content is preferably 0.5% by mass or more, more preferably 0.7% by mass or more. If it is less than 0.1% by mass, the amount of physical stabilizer for aqueous cosmetics required to obtain an effective effect may become 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. If it is more than that, it will not be completely dissolved and precipitation will easily occur. In this case, by containing 50 to 90% by mass of polyhydric alcohol having 2 to 6 carbon atoms, it becomes easy to use as a physical property stabilizer.

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

When the polyhydric alcohol is contained in an amount of 50 to 90% by mass as described above, the water content in the physical property stabilizer of the present invention is preferably 5 to 27% by mass. When the water content 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, As the 3-1,6-glucan content becomes relatively low, even if fluidity is observed immediately after blending, it may become gel-like over time and fluidity may decrease.

The physical property stabilizer of the present invention has a strong effect of stabilizing emulsions even in low-viscosity aqueous liquids, and therefore can be particularly suitably used as an "emulsion stabilizer."
In addition, the physical property stabilizer of the present invention has a large effect of suppressing sedimentation and stabilizing dispersion when it contains particulate components that do not dissolve in water, such as titanium oxide or zinc oxide, even in a low-viscosity aqueous liquid. Therefore, it can be particularly suitably used as a "dispersion stabilizer".

This shall include those in which the amount is dispersed.

The proportion of the aqueous phase is preferably 50 to 100% by mass, more preferably 60 to 100% by mass, and most preferably 80 to 100% by mass, based on the aqueous cosmetic.

Note that the rotational speed when measuring with a rotational viscometer can be appropriately set between 1 and 100 rpm depending on the device and viscosity. For example, when using TV-20 (cone plate rotational viscometer) manufactured by Toki Sangyo Co., Ltd., measurement is performed at a rotational speed of 5 rpm at 20 to 600 mPa·s.

Aqueous cosmetics with a viscosity higher than 200 mPa・s are relatively unlikely to have unstable physical properties, and solutions other than the physical stabilizer for aqueous cosmetics of the present invention can also be selected. The superiority of the agent becomes smaller.
