Description

  The present invention relates to an additive for improving the emulsion stability of a specific emulsion composition, a cosmetic composition containing the additive, and a method for improving the emulsion stability of the cosmetic composition.

Cosmetic compositions with an aqueous phase as a continuous phase are used in a wide range of applications as cosmetics because of their familiarity with the skin and excellent usability. There is a problem that emulsification tends to become unstable. In particular, low-viscosity cosmetics such as emulsions and lotions are prone to problems such as emulsification breaking over time and separation of the oil phase and aqueous phase, and emulsion floating and sedimentation (creaming).
Therefore, a method of stabilizing by adding a water-soluble polymer in the aqueous phase and increasing the viscosity has been studied. Among these, (patent document 1)-(patent document 3) are mentioned as examination which uses a xanthan gum.

  (Patent Document 1) includes 0.5 to 2.0% by weight of xanthan gum as an A component and one or two selected from polyhydric alcohol-containing plant extracts extracted with a polyhydric alcohol or polyhydric alcohol as a B component. The emulsification type skin external preparation characterized by containing the above and content of B component with respect to A component is 3 times weight or more is disclosed.

  (Patent Document 2) discloses a cosmetic 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) includes 0.7 to 1.5% by weight of xanthan gum as the A component, one or more oily components that are liquid at room temperature as the B component, and a semisolid oily component that is semisolid at room temperature as the C component. 1 type or 2 types or more and 1 type or 2 types or more of solid oily components which are solid at normal temperature as D component, and the content of all oily components B to D with respect to A component is 7 times weight or more, An oil-in-water emulsified cosmetic is disclosed.

  Moreover, as an examination using carrageenan, (patent document 4) is mentioned, Addition for cosmetics 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, each method has a certain effect on stabilization such as emulsification, but the feeling of use will be different depending on the content at which the effect is obtained, and stickiness will come out particularly when xanthan gum is used. Therefore, there was a problem that the usage was limited. Therefore, it is required to obtain a cosmetic that is stable in emulsification while suppressing the amount of water-soluble polymer such as xanthan gum used.

  On the other hand, polyhydric alcohols such as butylene glycol and propylene glycol are widely used because they have an effect as a moisturizing agent and preservative. Polyhydric alcohols have an effect of stabilizing the emulsified state to some extent, but the effect is insufficient, and an effect that suppresses the amount of water-soluble polymer used cannot be expected.

  Therefore, an object of the present invention is to provide an additive for stabilizing the emulsion composition for a long period of time, to provide a cosmetic composition that is stable for a long period of time, and to improve the emulsion stability of the cosmetic composition. It is to provide a way to do.

As a result of various studies to solve the above-mentioned problems, the present inventors coexisted a specific amount of polyhydric alcohol and a β-1,3-1,6-glucan in an amount significantly lower than the amount conventionally used. It was found that an excellent emulsification stabilizing effect can be obtained when it is used.
This is a surprising result for β-1,3-1,6-glucan that has been used for the purpose of improving the moisturizing action and the feeling of use.

  When the emulsification stability improver of the emulsion composition of the present invention is used, the emulsion stability of the emulsion composition can be greatly increased over a long period of time. Moreover, when the said emulsion composition is cosmetics, it does not produce a change in a usability | use_condition.

FIG. 1 shows the condition of emulsification stability depending on the content of 1,3-butylene glycol (in the figure, 1,3-butylene glycol is described as “BG”, the same shall apply hereinafter) under the condition that an emulsification stability improver is not included. It was investigated how it changes. In the “preparation of cosmetic composition” described in the examples, the emulsification stability improver is fixed at 0% by mass, and 1,3-butylene glycol is 0% by mass, 5% by mass, or 10% by mass. The emulsion was prepared by the same method and composition as the cosmetic composition described in the examples, and the emulsion stability was evaluated. FIG. 2 shows how the emulsification stability changes depending on the content of the emulsification stability improver only under the condition of containing 0.2% by mass of glycerin as the polyhydric alcohol. In “Preparation of cosmetic composition” described in Examples, 1,3-butylene glycol was fixed to 0% by mass, and the emulsion stability improver was β-1,3-1,6-glucan, 0% by mass. , 0.001% by mass, and 0.01% by mass, and were prepared by the same method and composition as the cosmetic composition described in the examples, and the emulsion stability was evaluated. As can be seen from this result, in the emulsion composition containing polyhydric alcohol at less than 0.5%, the effect of the emulsion stability improver of the present invention is not sufficient. FIG. 3 shows the effect of the emulsification stability improver with the content of 1,3-butylene glycol fixed at 5% by mass. In “Preparation of cosmetic composition” described in Examples, 1,3-butylene glycol is fixed at 5% by mass, and the emulsion stability improver is β-1,3-1,6-glucan, 0% by mass. , 0.001% by mass, and 0.01% by mass, and were prepared by the same method and composition as the cosmetic compositions described in the examples, and the emulsion stability was evaluated. FIG. 4 shows the effect of the emulsification stability improver with the content of 1,3-butylene glycol fixed at 10% by mass. In “Preparation of cosmetic composition” described in Examples, 1,3-butylene glycol is fixed at 10% by mass, and the emulsion stability improver is 0% by mass as β-1,3-1,6-glucan. , 0.001% by mass, and 0.01% by mass, and were prepared by the same method and composition as the cosmetic composition described in the examples, and the emulsion stability was evaluated.

The emulsification stability improver (hereinafter sometimes simply referred to as “emulsification stability improver”) of the emulsified composition of the present invention comprises 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, with 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. In addition, as β-1,3-1,6-glucan used in the present invention, those having a bond such as β-1,4-glycoside bond in part can also be used. The content of glucoside bonds other than bonds and β-1,6-glycoside bonds must be 10 mol% or less with respect to the total of β-1,3-glycoside bonds and β-1,6-glycoside bonds.

  Any β-1,3-1,6-glucan can be used as the β-1,3-1,6-glucan in the emulsion stability improver of the present invention, but the solubility is good. For this reason, β-1,3-1,6-glucan represented by the following general formula (1) is preferable:

  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 preferably a number that makes the mass average molecular weight of β-1,3-1,6-glucan represented by the general formula (1) 3000 to 5,000,000. ~ 1 million is more preferable, and 10,000 to 500,000 is most preferable. In the present invention, the mass average molecular weight of β-1,3-1,6-glucan is a pullulan conversion when gel permeation chromatography (also referred to as GPC) analysis is performed using water as a solvent. It refers to the weight average molecular weight. The “mass average molecular weight” may 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, using several kinds of pullulans with known molecular weights (concentration is arbitrary), a calibration curve (with x-axis holding time, (y-axis is molecular weight). Next, it is common to measure a sample (concentration is arbitrary) and calculate the relative molecular weight (molecular weight in terms of pullulan) from the retention time using the calibration curve.

  However, because pullulan and β-1,3-1,6-glucan have different molecular sizes due to structural differences even with the same molecular weight (the same number of glucose units), gel shake chromatography, which is a molecular sieve, can only obtain relative values. However, it is possible to calculate the intrinsic molecular weight approximated to the absolute value by correcting. Examples of the correction include a method of measuring the concentration of the specimen and 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 in which the concentration of β-1,3-1,6-glucan is measured by the phenol sulfuric acid method is accurately measured, and an aqueous solution with a known concentration is prepared as a specimen. Then, the molecular weight is calculated from the values measured by the differential pressure viscosity detector, the suggestive refraction detector, and the light scattering detector.

  In the general formula (1), the ratio of b to a is preferably 0.2 to 1 and more preferably 0.5 to 0.95 in that the effect of the present invention is more clearly exhibited. More preferred is 0.6 to 0.9. The unit with the repetition number a and the unit with the repetition number b may be combined in a random manner or in a block shape.

  Β-1,3-1,6-glucan represented by the general formula (1) is a known method, for example, algae such as yeast, lactic acid bacteria, natto bacteria, acetic acid bacteria, koji molds, chlorella and spirulina, filamentous fungi, etc. In particular, β-1,3-1,6-glucan having a high moisturizing effect on the skin can be extracted from black yeast (Aureobasidiumu pullulans). In addition, β-1,3-1,6-glucan having better water solubility can be obtained from the black yeast culture solution, so that it can be particularly preferably used in the present invention, and the black of the deposit number FERM BP-8391. The yeast culture solution is more preferable because it contains β-1,3-1,6-glucan with a higher solid content purity (concentration in the solid content). The extraction method for β-1,3-1,6-glucan is not particularly limited, and may be a known method.

  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, vacuum drying, and the like. Heat drying, extraction with a solvent or supercritical fluid, precipitation recovery, freeze-thawing, and the like can be mentioned, and these can be combined as appropriate.

  The emulsification stability improver of the present invention preferably contains the β-1,3-1,6-glucan in an amount of 0.1% by mass or more based on the total amount of the emulsification stability improver, The content is preferably 0.5% by mass or more, and more preferably 0.7% by mass or more. If the content is lower than 0.1% by mass, the amount of the emulsion stability improver necessary for obtaining an effective effect may be excessive.

  The emulsification stability improver of the present invention can exhibit an effect when used in combination with a specific amount or more of a polyhydric alcohol, and is an emulsion composition in which the polyhydric alcohol is present at less than 0.5% by mass. Even if an improver is blended, the emulsion stabilization effect cannot be obtained.

  The reason why such an effect is obtained is not clear, but the emulsification stability improver forms a gentle network with the polyhydric alcohol to keep the emulsion in a stable state, particularly suppressing daily creaming. I believe that.

Evaluation criteria for emulsion stability:
The destabilization of emulsification with time progresses in the flow of floating (creaming) and aggregation of the uniformly dispersed emulsion, and subsequent coalescence. Along with destabilization, a transparent aqueous phase is produced in which the emulsion is separated or broken. In this evaluation, the amount of the transparent aqueous phase produced by separating or breaking the emulsion was defined as the “floating rate (ratio of the transparent aqueous phase)”, and was used as a measure of emulsion stability. . The lower the “floating ratio”, the better the emulsion stability.
