Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment composition for imparting hair / strain to hair.

[0002]

2. Description of the Related Art Among the worries about hair, there are not a few problems related to low elasticity of hair, such as lack of elasticity / strain and lack of volume. In order to satisfy the desires of those who have these concerns, many hair treatment agents have been used in the past, which contain a balm / strain-imparting agent and a conditioning agent. However, most of these are effective due to the adsorption of the agent on the hair surface, etc., and they are dropped during hair washing, and therefore must be constantly treated, which is a troublesome task. It was In addition, attempts have been made to penetrate the inside of the hair to exert the effect, but the penetrability into the hair is poor, the treatment takes a long time, and the effect is not sufficient.

[0003]

Under such circumstances, as a result of intensive studies by the present inventor, the treatment agent prepared by combining benzophenone sulfonic acids and an organic solvent was
The present invention has been completed by finding that short-time treatment improves the elasticity of hair, gives hair a firmness / strain, and this elasticity is retained for a long time.

Accordingly, the present invention provides a hair treatment composition containing the following components (A) and (B) (A) organic solvent (B) benzophenone sulfonic acids.

In the present invention, the organic solvent (A) is preferably a compound represented by the following formula (1), an N-alkylpyrrolidone represented by the following formula (2) or an alkylene carbonate having 1 to 4 carbon atoms. Can be mentioned.

N-lauryl pyrrolidone etc. are mentioned.

The organic solvent (A) may be used alone or in combination of two or more, and the blending amount thereof is 0.5 to 50.
% Weight (hereinafter, simply indicated by%), particularly 2 to 30% is preferable. If it is less than 0.5%, the effect is not sufficiently exerted, and if it exceeds 50%, the effect is not improved. Also,
The mixing ratio of water and the organic solvent depends on the water solubility of the solvent, but is preferably solvent: water = 20: 80 to 50:50.

In the present invention, examples of the benzophenone sulfonic acids (B) include those represented by the following general formula (3).

[0011]

[Chemical 3]

[In the formula, at least one of A ^{1 to} A ¹⁰ represents a sulfonic acid group or a salt thereof, and the other represent a hydrogen atom, a halogen atom,
Hydroxyl group, carboxyl group, lower alkyl group, lower alkenyl group, lower alkoxy group or acyl group]

Specific examples of the benzophenone sulfonic acids (B) include oxybenzone sulfonic acid, dihydroxydimethoxybenzophenone disulfonic acid, o-chlorobenzophenone sulfonic acid, p-chlorobenzophenone sulfonic acid, 4,4'-dichlorobenzophenone sulfonic acid, 2,4'-dichlorobenzophenone sulfonic acid, 2,4-dichlorobenzophenone sulfonic acid, 2-
Hydroxybenzophenonesulfonic acid, 4-hydroxybenzophenonesulfonic acid, 2-aminobenzophenonesulfonic acid, 4-aminobenzophenonesulfonic acid, 2
-Methylbenzophenonesulfonic acid, 4-methoxybenzophenonesulfonic acid, 4,4'-dimethylbenzophenonesulfonic acid, 4,4'-dimethoxybenzophenonesulfonic acid, 4-chloro-4'-hydroxybenzophenonesulfonic acid and their sodium salts, Examples thereof include potassium salt, lithium salt, calcium salt, ammonium salt, and organic quaternary ammonium salt.

Benzophenonesulfonic acid (B) is 1
One kind or two or more kinds can be used in combination, and the blending amount thereof is preferably 0.1 to 10%, particularly preferably 1 to 5%. 0.1
If it is less than 10%, the effect of hair treatment is not sufficient, and if it exceeds 10%, the effect corresponding to the increase cannot be obtained.

To the hair treatment composition of the present invention, an acid or an alkali is further added to adjust the pH to a specific range. This is because the hair is sufficiently swollen so that the benzophenonesulfonic acid can penetrate into the hair. Effective to promote. That is, the pH of the composition is adjusted to 2 to 5 when an acid is added, and the pH of the composition is adjusted when an alkali is added.
Is preferably adjusted to 8 to 11. If the pH of the composition is below 2 or above 11, hair may be damaged. Regarding the swelling of hair by acid or alkali, the research report by Bat et al. [G. Ramachandra Bhat et.
al. , J. Soc. Cosmet. Chem. , 32
f, 393-405 (1981)], and in this report, hydrochloric acid is used as an acid and sodium hydroxide is used as an alkali. However, since the hair itself is an ion exchanger, the acid is used as an acid in the present invention. Is preferably an organic acid or phosphoric acid, and the alkali is preferably ammonia or an organic amine.

The above-mentioned organic acids include citric acid, glycolic acid, succinic acid, tartaric acid, lactic acid, acetic acid, fumaric acid, malic acid, levulinic acid, butyric acid, valeric acid, oxalic acid, maleic acid, phthalic acid, mandelic acid. Etc. Examples of the organic amine include monoethanolamine, diethanolamine, triethanolamine, aminohydroxymethylpropanediol, 2-amino-2-methyl-1.
-Propanol, 2-amino-2-methyl-1,3-propanediol, and basic amino acids such as arginine.

These acids or alkalis can be used singly or in combination, and the amount of which the pH of the composition is in the above range is preferably 0.3 to 50% in the composition, more preferably 0. 5 to 30% is blended. If the blending amount is less than this, there is no swelling effect due to the ion-exchange ability of the hair, and further blending does not show any further increase in the effect.

In the hair treatment composition of the present invention, the balance of the components other than the above-mentioned organic solvent (A), benzophenonesulfonic acid (B) and acid or alkali is usually water. Also,
The hair treatment composition of the present invention preferably contains a sodium salt, potassium salt, ammonium salt or the like of an organic acid to form a buffer system.

Further, in the hair treatment composition of the present invention, a thickening agent such as hydroxyethyl cellulose, a surfactant, a perfume, a pearling agent, a dye, and the like, if necessary, within a range not impairing the effects of the present invention. You may mix | blend a ultraviolet absorber, an antioxidant, a preservative, etc. Further, in order to improve the feel of hair or skin, a cationic polymer such as cationized cellulose and a silicone derivative such as dimethylpolysiloxane or amino-modified silicone can be blended.

The hair treatment composition of the present invention can be used, for example, by applying it to hair for a certain period of time, preferably 5 to.
After leaving it for 30 minutes, it may be washed out. While standing, it may be heated to a suitable temperature, preferably 30 to 50 ° C. The hair to be applied may be dry or wet after washing.
