Description

  The present invention relates to a hair cosmetic used as a hair conditioner such as hair wax or hair cream, or as a base for the same.

  Hair styling agents are used for the purpose of preparing and maintaining hair in a desired shape, and there are various forms such as a spray type, a lotion type, a gel type, and a foam type. Conventionally, a film forming agent and a solid oil have been widely used in order to impart hair styling properties to hair. The film-forming agent forms a film on the hair and fixes the hair. Various hair-fixing polymers having anionic, nonionic, amphoteric and cationic properties are used as a set agent. It is produced by using a material dissolved in a solvent such as water or lower alcohol as a skeleton, and further adding a thickener and optionally a propellant or the like (see, for example, Patent Documents 1 and 2). However, hair styling using such a hair fixing polymer as a set agent has the effect of fixing the hairs together to hold the set, and is excellent in set holding power, but is applied to the hair. In the process up to the drying finish, there was a stickiness, and it was not smooth. Further, after drying, there was a drawback that the hair was stiff and lacked re-styling.

  On the other hand, solid oils such as waxes and waxes have the advantage that re-hairdressing is easy, although hair retention is inferior compared to the case of using a film-forming agent because the hair is fixed by its adhesiveness. . However, when blended with a large amount of solid oil components to increase the hair-styling retention power, there is a problem that not only is the solid oil-specific wrinkle easy to occur, but there is also a sticky feeling and the usability as a product that is difficult to stretch (e.g. (See Patent Documents 3, 4, and 5). In addition, some hair cosmetics contain liquid oil to improve usability and improve usability. However, there are problems such as poor hair holding ability, swells and splashes, and hair is hard to bundle. It was.

  In order to solve such a problem, an attempt has been made to reduce the sticky feeling peculiar to oil while maintaining the hair holding power. For example, hair cosmetics (for example, see Patent Document 6) combined with an oil such as silicone and a polymer compound, oil-in-water hair containing a solid or semi-solid wax at normal temperature, and hydrocarbon oil and / or ester oil Cosmetics (see, for example, Patent Document 7), hair creams containing waxes and silicone oil (for example, see Patent Document 8), and the like have been proposed.

JP 2003-171235 A Japanese Patent No. 4074607 JP 2001-213742 A JP 2007-297300 A JP 2009-13125 A Japanese Patent No. 2722221 Japanese Patent No. 36004337 JP 2002-370937 A

  However, even these attempts are not sufficient to satisfy both functionalities such as hair holding ability and setability, and usability such that there is no stickiness and ease of stretching, and it is not yet satisfactory. Furthermore, since the oil component is used in a high blending amount, there have been problems of storage stability such as rough dough, reduced viscosity and liquefaction due to temperature changes during product storage.

  Therefore, the present invention achieves a finish without stickiness while having high hair retention and excellent hair setting property, and is excellent in usability such as non-stickiness, good stretch and good storage stability. The issue is to provide a fee.

  In view of such circumstances, the present inventors have conducted intensive studies, and as a result, a film-forming agent selected from vinylpyrrolidone / vinyl acetate copolymer and N-vinylpyrrolidone / (meth) acrylamide / vinylimidazole copolymer, By combining waxes, solid or pasty hydrocarbons at normal temperature, higher fatty acid salts, and water, it achieves a finish without stickiness while having high hair retention and excellent hair setting properties, The present invention has been completed by finding that a hair cosmetic composition that is excellent in usability such as being non-sticky and has good stretchability and excellent storage stability can be obtained.

  That is, the present invention comprises (A) one or more film forming agents selected from (A) vinyl pyrrolidone / vinyl acetate copolymer and N-vinyl pyrrolidone / (meth) acrylamide / vinyl imidazole copolymer, and (B) solid at room temperature. The present invention provides a hair cosmetic characterized by containing waxes, (C) hydrocarbons that are solid or pasty at normal temperature, (D) higher fatty acid salts, and (E) water.
