Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oily cosmetic, and more specifically, it contains 12-hydroxystearic acid and an ester oil having a sterol skeleton in its structure, and has excellent transparency and usability ( The present invention relates to an oily cosmetic having good adhesiveness, spreadability, sustainability) and strength characteristics. still,
The oily cosmetic according to the present invention refers to an oily cosmetic containing substantially no water.

[0002]

2. Description of the Related Art Heretofore, transparent oily cosmetics have been widely known in the form of paste or liquid, and the solid ones are those containing resins (polymer substances) such as polyamide resin and ester gum. There were only a few (Japanese Patent Publication No. 45-41318 and Japanese Patent Publication No. 52-706).
No. 7, JP-B-63-119405). However, these cosmetics are not always satisfactory in terms of transparency and usability, particularly transparency.

Therefore, in recent years, transparent solid cosmetics using 12-hydroxystearic acid as a solidifying agent have been developed. A gel using 12-hydroxystearic acid has low tackiness, good extensibility and excellent adhesion to the skin, and has little hardness change over a wide temperature range.
The transparency is also good. As a transparent solid cosmetic using 12-hydroxystearic acid as a solidifying agent, there is disclosed in Japanese Patent Laid-Open No.
It is described in JP-A-3-119405, JP-A-2-264707, JP-A-4-91011 and the like. JP-A-63-119405 proposes a transparent solid cosmetic composition in which the polyhydric alcohol ester of rosin of 12-hydroxystearic acid and the polyhydric alcohol side chain fatty acid moiety contain an ester or a polyhydric alcohol unsaturated fatty acid ester. ing. JP-A-2-264707 proposes a transparent solid cosmetic composition comprising 12-hydroxystearic acid, heavy liquid paraffin, and a liquid oil component. Further, JP-A-4-91011 proposes a transparent cosmetic composition comprising a transparent liquid oil having a hydroxyl value of 120 or less and triglyceride. However, these transparent cosmetics are characterized by poor spread and stickiness during application, and easy makeup breakage. Further, in the case where the shape of a lipstick or the like is formed into a stick shape, if the stick strength is emphasized, the blending amount of 12-hydroxystearic acid is increased, so that the transparency is deteriorated. On the contrary, when the compounding amount of 12-hydroxystearic acid is small, transparency is obtained,
Sufficient strength was not obtained, and there were problems such as breaking, deformation and softening during use. Therefore, it is difficult to obtain a solid oily cosmetic which is transparent, has a good feeling in use, and has high strength.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION 12- used in the present invention
Hydroxystearic acid is a white or pale yellow waxy solid, and is generally obtained by reducing ricinoleic acid obtained from castor oil or the like.

The compounding amount of 12-hydroxystearic acid in the present invention is based on the mass of the product (hereinafter the same).
The content is preferably 2.0 to 40.0 mass%, more preferably 5.0 to 20.0 mass%. When the content of 12-hydroxystearic acid is less than 2.0% by mass, solidification is insufficient, and when it exceeds 40.0% by mass, the transparency decreases.

The ester oil having a sterol skeleton in its structure in the present invention means an ester obtained by esterifying sterol with an acid such as fatty acid or amino acid. These ester oils may be used alone or in combination of two or more.

Sterols are present in almost all organisms such as vertebrates, plants, yeasts, algae, etc. Cholesterol is an animal sacrificial sterol, which is a ceramide between keratinocytes,
It is known as an important component that forms a lamellar structure with fatty acids and has a barrier function of protecting against external agitation and suppressing evaporation of water from the inside. For plants,
There are β-sitosterol, campesterol, stigmasterol, brassicasterol, and the like, called plant sterol (phytosterol), which is a constituent component of the plasma membrane of plants, and has a role similar to that of cholesterol, which is a constituent component of cell membranes in animals. Is known to be responsible for.

Sterols generally have a high melting point. For example, cholesterol has a high melting point of about 149 ° C., and phytosterols have similar melting points. Therefore, sterol has low solubility in an oil agent, and crystals are likely to precipitate. Therefore, it is not preferable in terms of transparency.
Esterification of sterols lowers the melting point and improves solubility in oil agents. Therefore, when using an ester oil having a sterol skeleton in its structure,
-The amount of hydroxystearic acid can be increased, and excellent stick moldability can be added. Further, when used alone in 12-hydroxystearic acid, the transparency is maintained even if a considerable amount of an oil agent such as an α-olefin oligomer or squalane, whose transparency is significantly lowered, is blended. The usability of cosmetics can be significantly improved.

Specific examples of the sterol used in the present invention include phytosterol, campesterol, campestanol, 22-dehydrocampesterol, stigmasterol, stigmasteranol, 22-dihydrospinesterol, 22-dehydrostigmasteranol, 7-dehydrostigmasterol, sitosterol, cycloartenol, tilcarol, euphor, fucostol,
