Furthermore, the composition of the present invention suppresses squeaking sensation and provides a moist / fresh feeling, and therefore provides an excellent feel when applied to the skin. Furthermore, in the composition of the present invention, precipitation of crystals of dipotassium glycyrrhizinate is also suppressed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The present invention will now be described. The composition of the present invention contains (A) dipotassium glycyrrhizinate and (B) a polyhydric alcohol.

[0009] (A) Dipotassium glycyrrhizinate may be an artificially synthesized product or may be obtained from a natural product such as a plant. Dipotassium glycyrrhizinate may also be provided in the form of a plant extract containing the same.

[0010] Dipotassium glycyrrhizinate may be a commercially available product, or may be extracted from, for example, a plant of the genus Glycyrrhiza of the family Leguminosae. The species include Spanish licorice (G. glabra), Ural licorice (G. uralensis), Examples include G. inflata.

[0011] The method of extracting dipotassium glycyrrhizinate from a plant of the genus Glycyrrhiza of the family Leguminosae is not particularly limited, and may be a conventional extraction method, that is, a 1-20-fold amount of water or a lower alcohol such as ethanol is added to the plant body or a processed product thereof as a solvent, and the mixture is stirred as required, and immersed for several days at room temperature or for several hours at a temperature near the boiling point, and insoluble matter is removed by filtration or the like, and then the solvent is removed by distillation under reduced pressure or the like as required, and the mixture may be purified and fractionated by column chromatography or the like, and used. A preferable example of a plant part for preparing a plant extract is, for example, an underground stem.

[0012] In the composition of the present invention, the content of component (A) is 0.2 to 1.0% by mass based on the entire composition. Within this range, stickiness is unlikely to occur, and excellent usability such as a squeaky feeling, a moist feeling, and a fresh feeling is easily obtained, and crystal precipitation is also suppressed. If the content of component (A) is less than 0.2% by mass, the desired effect is difficult to obtain, and if it exceeds 1.0% by mass, the desired effect is not obtained or the freedom of formulation of the composition is impaired. In addition, the content of component (A) may be 0.2% by mass or more, 0.3% by mass or more, or 0.5% by mass or more based on the entire composition, and may be 1.0% by mass or less, 0.8% by mass or less, or 0.7% by mass or less, or a combination thereof that is not contradictory. In addition, the content of component (A) may be 0.2 to 1.0% by mass, 0.3 to 0.8% by mass, or 0.5 to 0.7% by mass based on the entire composition.

There are no particular limitations on these polyhydric alcohols, so long as they are normally contained in cosmetic compositions, and commercially available products can be used.

[0014] In the composition of the present invention, the total content of component (B) is not particularly limited, and may be, for example, 0.01 mass% or more, 0.05 mass% or more, or 0.1 mass% or more, and 20 mass% or less, 15 mass% or less, or 10 mass% or less, or a compatible combination thereof, based on the entire composition. Also, the content of component (B) may be 0.01 to 20 mass%, 0.05 to 15 mass%, or 0.1 to 10 mass% based on the entire composition. By using the component (A) in this range, the cosmetic composition will feel less sticky after application, and will also be more likely to provide a more excellent feel when used, such as no squeaky or dry feeling, and will also be more likely to provide formulation stability.

[0015] In the composition of the present invention, the mass ratio of the contents of component (A) and component (B) is not particularly limited, but from the viewpoints of usability, formulation stability, and the like, it is, for example, preferably 1:75 to 20:1, and more preferably 1:50 to 10:1.

A water-in-oil emulsion type composition was prepared according to the formulation shown in Table 3 by a conventional method.

[0049] The obtained compositions were evaluated for the following items, and the results are shown in Table 1.

[0050] (Crystallization) Each composition was placed in a glass standard bottle and left to stand in a thermostatic chamber set at 0° C. for one month, after which a specialist evaluator visually evaluated the composition on the following four-point scale. ◎: No crystal precipitation is observed ○: Very little crystallization is observed △: A small amount of crystals was observed. ×: Crystal precipitation is observed

[0051] (Sticky feeling) An appropriate amount of the cosmetic product was applied to the skin, and a specialist evaluator scored the stickiness of the skin one minute after application according to the following criteria. 5 points: No sticky feeling 4 points: Almost no stickiness 3 points: Feels slightly sticky 2 points: Sticky feeling 1 point: Very sticky The average scores of the 10 evaluators were assigned to the following ratings. ◎: More than 4 points: Very good ○: More than 3 points and 4 points or less: Good △: More than 2 points, 3 points or less: slightly poor × : 2 points or less : Defective

[0052] (creaking sensation) An appropriate amount of the cosmetic was applied to the skin, and the feeling of squeaking on the skin during application was scored by a specialist evaluator according to the following criteria. 5 points: No creaking sensation 4 points: Almost no creaking sensation 3 points: Slight creaking sensation 2 points: Creaking sensation 1 point: Very squeaky The average scores of the 10 evaluators were assigned to the following ratings. ◎: More than 4 points: Very good ○: More than 3 points and 4 points or less: Good △: More than 2 points, 3 points or less: slightly poor × : 2 points or less : Defective

[0053] (Moisturizing / freshness) An appropriate amount of the cosmetic product was applied to the skin, and expert evaluators scored the skin's moisturizing / moisturizing feeling one minute after application according to the following criteria. 5 points: Very moist / feels fresh 4 points: Moist / feels fresh 3 points: Slightly moist / feels fresh 2 points: Almost no moist feeling 1 point: Not moist / refreshing The average scores of the 10 evaluators were assigned to the following ratings. ◎: More than 4 points: Very good ○: More than 3 points and 4 points or less: Good △: More than 2 points, 3 points or less: slightly poor × : 2 points or less : Defective

[0060] The compositions of the examples containing components (A) and (B) are less likely to become sticky. Furthermore, it was found that the product had an excellent feel when used, such as a lack of squeaking sensation and a moist / fresh feeling, and also had excellent formulation stability, with crystal precipitation being suppressed. [Industrial Applicability]

[0061] The composition of the present invention can be preferably applied to external preparations for the skin, such as cosmetics, cosmetics including quasi-drugs, and medicines.
