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 imparts excellent water retention ability and supple feel to hair.

[0002]

2. Description of the Related Art Conventionally, hair cosmetics have been required to have the functions of improving the water retention of hair, imparting a supple feel, and maintaining them. Therefore, moisturizers such as glycerin and pyrrolidone carboxylate are required. , Lanolin, liquid lanolin, oil hydrates such as cholesterol fatty acid ester, hydrolyzed proteins, amino acids and the like are blended. However, glycerin and the like have high hygroscopicity but low water retention, and have little effect of improving the water retention of hair.Moreover, hydrating oils such as lanolin have tackiness per se and have a supple feel. It is not preferable in giving. In addition, hydrolyzed proteins, water-retaining amino acids and the like are solid substances and give a rough feel, and it is difficult to say that they are supple. Therefore, there is a demand for the development of a hair cosmetic composition which has excellent water retention properties on the hair and is preferable in terms of feel.

[0003]

Means for Solving the Problems As a result of earnest studies by the present inventor on a hair cosmetic composition that imparts excellent water retention and feel to hair, (A) cholesterol fatty acid ester, dihydrocholesterol fatty acid ester, lanolin, lanolin alcohol , And one or more oils selected from the group of liquid lanolin and (B) proline in a hair cosmetic composition, synergistically improving the water-retaining ability of the hair and further imparting a supple feel to the hair. The present invention has been completed and the present invention has been completed.

The component (A) used in the present invention can be used in combination with one or more selected from the group consisting of cholesterol fatty acid ester, dihydrocholesterol fatty acid ester, lanolin, lanolin alcohol, and liquid lanolin. That is, the cholesterol fatty acid ester and the dihydrocholesterol fatty acid ester are cholesterol or an ester of dihydrocholesterol and a linear or branched fatty acid having 8 to 22 carbon atoms or a mixture thereof, and for example, cholesteryl oleate (YOFCO LC-CO; manufactured by Yoshikawa Oil & Oil Co., Ltd.). ), Lanolin fatty acid cholesteryl (YOFCO CLE-NH; made by Yoshikawa Oil), cholesteryl nonanoate (YOFCO LC-C)
N; made by Yoshikawa Oil Co., Ltd., dihydrocholesteryl isostearate (YOFCO LC-DIS; made by Yoshikawa Oil Co., Ltd.), cholesterine hydroxystearate (Saracos HS; made by Nisshin Oil Co., Ltd.) and the like. In addition, component (B), proline, is a known neutral amino acid.

In the present invention, the total amount of these components (A) and (B) is 1 to 30% by weight, preferably 5 to 2%.
When the total content is less than 1% by weight, the water-retaining ability is not sufficiently imparted to the hair, and when it exceeds 30% by weight, a supple feel is not obtained and a sticky or stiff feeling is not obtained. The feeling is so strong that a good feeling cannot be obtained.

The mixing ratio (weight ratio) of component (A): component (B) is 10: 1 to 1:10, preferably 7: 3 to 3: 7. (A) (B) Within this blending ratio range, the water retention is improved as compared with the case of (A) or (B) alone, and the hair is given a supple feel. But,
Even if (A) and (B) are used together, if the ratio is out of the above range, the combined effect does not appear.

The form of the hair cosmetic composition of the present invention is not particularly limited, and may be a form such as an emulsion, a blowing agent, a hair rinse, a hair treatment, a hair mousse or a hair essence. Further, other compounding ingredients are not particularly limited, and those which are usually compounded in this kind of cosmetics can be used. Further, if necessary, the hair cosmetic composition of the present invention can be appropriately blended with known components within a range that does not impair the performance thereof, and examples thereof include oil components such as dimethylpolysiloxane, triglyceride, ester oils and waxes. Coloring agents, fragrances, pH adjusting agents such as phosphoric acid and citric acid, pyrrolidonecarboxylic acid salts, moisturizing agents such as lactic acid, water,
Examples thereof include solvents such as ethanol, antistatic agents such as cationic surfactants, and ultraviolet absorbers.

EXAMPLES Next, the present invention will be described in more detail with reference to examples. In addition, the compounding amount in the examples and comparative examples means% by weight. Needless to say, the present invention is not limited to these examples.

The evaluation was carried out by the following method. 1. Evaluation Method (1) Water Retention of Hair A bundle of hair (100 hairs, length 10 cm) was used in Examples 1 to 1.
7 and each of the test samples of Comparative Examples 1 to 5 are immersed for 30 minutes, and the weight (W) after standing for 24 hours under the conditions of 20 ° C. and relative humidity of 44% is measured. Then, it is dried at 55 ° C. for 3 hours and the weight (W2) is measured. Weight of hair bundle (100 hairs, length 10 cm) (W0)
After being measured, the sample is immersed in water and dried at 55 ° C. for 3 hours, and the weight (W1) is measured. Calculate the change in water retention rate (%) of the hair using the following formula: 30%
With the above, the water retention capacity can be satisfied.

[Equation 1]

(2) Suppleness of Hair Each test sample was subjected to a usage test by 10 professional panelists (female) and evaluated by sensory evaluation according to the following criteria. 4 points: Gives a fairly supple feel. 3 points: Gives a slightly supple feel. 2 points: No change. 1 point: Gives a slightly sticky, rough or stiff feel. 0 points: Gives a considerably sticky, rough or stiff feel. The average value of these 10 persons was set as the suppleness of the hair and ranked as follows. 2.7-4.0 points: ○ 1.4-2.6 points: △ 0-1.3 points: ×

(3) Comprehensive Evaluation ◎: Water retention of hair is 30% or more, and suppleness of hair is ○ ◯: Water retention of hair is 30% or more, and suppleness of hair is Δ ×: Water retention of hair Is less than 30%, and the suppleness of the hair is x. The results are shown in Table 1.
