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

[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.

The content of component (B) may be 0.01 to 10% by mass, 0.025 to 5% by mass, or 0.05 to 1% by mass, based on the total 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.

[0016] 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 1:25 to 40:1, and more preferably 1:5 to 20:1.
