Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition which does not make the hair sticky but continuously gives the hair an excellent moist feeling and luster.

[0002]

2. Description of the Related Art Heretofore, silicone derivatives, polyhydric alcohols, and set resins have been widely used in order to give hair a moist feeling and gloss. However, the addition of a silicone derivative gives the hair a moist feeling and luster, but the effect is temporary and not lasting. Further, when a polyhydric alcohol is added, the effect continues, but an unpleasant sticky feeling is given. With the set resin, gloss was obtained, but no moist feeling was obtained, and there was a problem in that the set resin caused a tingling sensation and impaired usability.

[0003]

In view of such circumstances, the present inventors provide hair with a long lasting moisturizing feeling and luster, and have excellent feeling of use without stickiness after application. It is to provide cosmetics.

[0004]

[Means for Solving the Problems] The inventors of the present invention have made extensive studies to solve the above problems, and have found that a copolymer of vinylpyrrolidone and a dialkylaminoalkyl methacrylate, a phospholipid, a protein, and a protein degradation product. The present invention has been completed by discovering that by combining one or more selected from protein derivatives, it is possible to provide a long-lasting glossy and moisturizing feeling to the hair, and to obtain a non-greasy hair cosmetic composition. Came to do.

The copolymer of vinylpyrrolidone and dialkylaminoalkylmethacrylate used in the present invention can be produced by copolymerizing vinylpyrrolidone and dialkylaminoalkylmethacrylate according to a conventional method, and its polymerized form is a random copolymer. It may be any of polymerization, block copolymerization and the like. Examples of the dialkylaminoalkyl methacrylate include those having two carbon atoms of 1 to 4 carbon atoms, preferably 1 to 2 carbon atoms. For example, dimethylaminomethyl methacrylate, dimeethylaminopropyl methacrylate, or dimethylaminoethyl methacrylate can be used. The molecular weight of the copolymer is 50,000 or more, preferably 1
It is desirable that the molecular weight is at least 0,000, and if the molecular weight is less than 50,000, moist feeling and luster persistence cannot be obtained, and it is not suitable for use. The copolymer contains 0.01 to 100 parts by weight of the total amount of cosmetics.
20% by weight, preferably 0.1 to 10% by weight. If the blending amount is less than 0.01% by weight, the moist feeling and the gloss effect are not sustained, and if it exceeds 20% by weight, the hair becomes sticky, which is not preferable.

The phospholipids used in the present invention are soybean phospholipids and hydrogenated products thereof, egg yolk phospholipids and hydrogenated products thereof, phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, sphingomyelin and diaroyl. Examples include phosphatidylcholine and dipalmitoylphosphatidylcholine. Further, the protein, protein hydrolyzate and protein derivative are proteins and their hydrolyzates and derivatives which are usually obtained from the natural world, and examples thereof include collagen, collagen hydrolyzate, cation hydrolyzed collagen, coconut oil fatty acid hydrolyzed collagen and keratin. , Keratin hydrolyzate, cationized hydrolyzed keratin, elastin, elastin hydrolyzate, casein, gelatin, soybean protein, wheat protein, silk protein, egg white and the like. Among these, egg yolk phospholipids, collagen and keratin are particularly preferable.

These phospholipids, proteins, protein degradation products and protein derivatives may be used alone or in combination of two or more,
It can be blended in an amount of 0.001 to 3.0% by weight, and particularly preferably 0.05 to 1.0% by weight, based on the total amount of the cosmetic. If the blending amount of these is less than 0.001% by weight, no moist feeling and persistence of luster are observed, and even if the blending amount exceeds 3.0% by weight, further improvement in effect is not observed. .

The hair cosmetic composition of the present invention is produced by mixing and stirring the desired components by a conventional method, and used in the form of emulsion, foamy hair styling agent, hair gel, hair spray, shampoo, hair treatment, hair color and the like. can do. Other components are not particularly limited, and alcohols, neutralizing agents, pH adjusters, fragrances and the like can be appropriately blended.

EXAMPLES Next, the present invention will be described in more detail with reference to Examples and Comparative Examples. In the following examples and comparative examples, [%] means% by weight. Needless to say, the present invention is not limited to these examples. The examples and comparative examples in Table 1 were prepared, and the moist feeling, luster persistence and stickiness were evaluated by the methods described below. The evaluation method is shown.

[Evaluation method] (1) Persistence of moist feeling About 2 g of a sample is applied to a hair bundle of about 10 g, and the moist feeling after standing for 8 hours at room temperature is applied according to the following criteria.
