Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a solid cosmetic containing fatty acid soap, kappa carrageenan and / or iota carrageenan, gellan gum, water-swellable clay mineral and water, and more particularly, to an excellent refreshing feeling when applied. The present invention relates to a solid cosmetic composition that transfers well to the skin and the like, does not cause deformation during use, has good spread and spread on the skin and the like, and has excellent stability over time.

[0002]

2. Description of the Related Art Conventionally, solid cosmetics are cosmetic preparations widely used in foundations, white powders, teak colors, eye shadows, etc., because of their portability and ease of use. Such solid cosmetics include a powder solid type in which powder and an oil component are mixed and compression-molded, an oily solid type in which oil is solidified with wax or the like, an oil solidified with wax or fatty acid soap, and a water-inner phase. And a water-based solid type obtained by solidifying water with a fatty acid soap or a water-swellable clay mineral. Among these various solid cosmetics, the type having a high water content and excellent refreshing feeling is an aqueous solid type.

[0003]

However, water-based solid type cosmetics in which water is hardened only with a fatty acid soap are difficult to control the hardness, and the so-called skin transfer in which the cosmetics adhere well to the skin is difficult. Not good. Also,
A water-based solid cosmetic in which water is solidified by using a fatty acid soap and a water-swellable clay mineral in combination may sometimes change in hardness over time, and it has been difficult to secure stability over time. Furthermore, the water-based solid type cosmetic in which water is solidified by using carrageenan as a water-soluble polymer in a fatty acid soap and a water-swellable clay mineral in combination has improved the skin transfer to some extent, but the stability over time is satisfactory. There was no standard. For this reason, it is excellent in refreshing feeling at the time of application, transfers well to the skin and the like, does not cause swelling when used, has good spread and spread on the skin and the like, and has excellent stability over time, and is an aqueous solid type solid cosmetic. The development of a fee was desired.

[0004]

Under such circumstances, the present inventors have conducted intensive studies, and as a result, in the aqueous solid type cosmetic, fatty acid soap, kappa carrageenan and / or iota carrageenan, gellan gum, water swelling. The present inventors have found that a solid cosmetic containing a clayey mineral and water solves the above-mentioned problems, and have completed the present invention.

That is, the present invention provides the following components (a) to
(E); (a) a fatty acid soap; (b) kappa carrageenan and / or iota carrageenan; (c) gellan gum; (d) a water-swellable clay mineral; It is. Further, the solid cosmetic, which contains 30 to 95% by mass of the component (e), and further contains the component (a)
1 to 20% by mass, a total of 0.5 to 5% by mass of the component (b) and the component (c), and 0.05 to 5% of the component (d), respectively. The present invention provides a solid cosmetic. Any one of the solid cosmetics described above, wherein the pH at 20 ° C. is 9 or less, and further comprising a powder other than the component (d) as the component (f). The present invention provides any of the above solid cosmetics, which further comprises an oily component as the component (g).

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The solid in the solid cosmetic of the present invention usually means a solid that is solidified in a temperature range (0 ° C to 50 ° C) in which the cosmetic is used.

The fatty acid soap of the component (a) used in the present invention may be a fatty acid soap which has been neutralized in advance, or may contain a fatty acid neutralized with an alkali in the production process. Examples of the fatty acid used for such component (a) include lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, 12-hydroxystearic acid, and the like, and one or more of these can be used. . Among these, in order to maintain the hardness of the solid cosmetic, it is preferable to select a fatty acid having a melting point of 50 ° C. or more, such as myristic acid, palmitic acid, stearic acid, behenic acid, or 12-hydroxystearic acid. Examples of the alkali to the fatty acid used in the component (a) include sodium hydroxide and potassium hydroxide. The neutralization amount is determined by the equivalent amount of the fatty acid. However, if the neutralization amount is such that a partially unneutralized fatty acid is present rather than completely neutralized, the increase in pH is suppressed. It is also preferable from the viewpoint of suppressing skin irritation.

[0008] The content of the component (a) in the solid cosmetic composition of the present invention is preferably 1 to 20% by mass (hereinafter simply abbreviated as "%") as fatty acid soap, and particularly preferably 1 to 10%. When used in this range, the hardness of the solid cosmetic can be maintained, and the affinity with the components (b) to (d) is good, so that a solid cosmetic having better stability over time can be obtained.

The carrageenan of the component (b) used in the present invention is a straight-chain galactan in which α (1 → 3) bonds and β (1 → 4) bonds are alternately repeated. β (1
→ 4) The bound galactose unit is partially or entirely present as 3,6-anhydro-D-galactose and sulfate. There are three types of carrageenan, kappa, iota and lambda, depending on their composition.
Kappa carrageenan is composed of α (1 → 3) -D-galactose-4-sulfate and β (1 → 4) -3,6-anhydro-D-galactose, and iota carrageenan has a structure similar to kappa carrageenan. But
All β (1 → 4) -3,6-anhydro-D-galactose is characterized by the presence of a 2-sulfate ester group. Lambda carrageenan is kappa,
It differs in structure from iota and consists of α (1 → 3) -D-galactose-2-sulfate and β (1 → 4) -D-galactose-2,6-disulfate. Iota carrageenan, a kappa with 3,6 glucosidic bonds, forms a thermoreversible gel, which is also affected by the presence of metal salts. Both kappa and iota types have high gel strength and are suitable for maintaining moldability and hardness. Lambda carrageenan having no 3,6 glucosidic bond is not preferred as the component (a) in the solid cosmetic of the present invention since it does not gel regardless of the presence of salts. Such a component (b) is commercially available as a kappa type product, GENUG.

It is a linear high molecular polysaccharide comprising four molecules of sugars of 4-linked glucuronic acid, 1-4-linked glucose and 1-4-linked rhamnose, and has one carboxyl group residue per one structural unit. Have. Native gellan gum contains one to one of the 1-3 linked glucose residues of gellan gum.
One residue of a glyceryl group and one half of an acetyl group are bonded per structural unit on average. In the state dissolved in water, both gellan gum and native gellan gum exist in a random coil shape, but gellan gum takes a double helix structure by cooling from the hydrated state,
Forms a strong gel. In addition, the double helix associates with the addition of the cations, forming a stronger and friable gel. When native gellan gum is cooled from the hydrated state, it takes a double helix structure and forms a gel, but since the acetyl group inhibits the association between the double helix,
It does not form a friable gel like gellan gum but forms a soft gel. As such a component (c), KELCOGEL AFT, K
