Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a hair treatment composition, particularly a hair treatment composition whose conditioning effect lasts for a long period of time.

[Conventional technology]

For hair, shampoo, brushing, hair dryer,
Due to physical or chemical causes such as perm, hair color, etc.
It gets damaged, hardens, and becomes electrically charged.

In order to maintain beautiful and healthy hair, it is necessary to prevent damage and soften the hair.

Conventionally, various ingredients have been added to hair cosmetics such as rinses and treatments for this purpose.

[Problem to be solved by the invention]

However, hair treatment agents that use quaternary ammonium salts, which are commonly used as additives in rinses and treatments, have limited adsorption power because their adsorption to hair is based on the mere affinity with the quaternary ammonium salts. is insufficient. That is, although it is resistant to swimming or sweating, it is washed away when exposed to washing operations such as shampoo, and its adsorption power cannot be said to be sufficient.

Furthermore, when shampoos containing cationized polymers that are currently available on the market are used, the cation/anion complex mainly adheres to the hair surface, so that the conditioning effect cannot be sustained.

Furthermore, when this shampoo is used, rinsing may actually impair the conditioning effect.

Therefore, an object of the present invention is to provide a hair treatment composition that can impart a sufficient conditioning effect to hair and maintain eye and eye effects for a long period of time.

[Means for Solving the Problem] As a result of intensive studies to achieve the above object, the present inventors found that when hair is treated with 2-hensyloxyethanol,
It was found that the hair swelled sufficiently. It has also been found that when an anionic polymer is further coexisted, the polymer penetrates deeply into the hair and can provide a lasting conditioning effect to the hair.

The present invention has been made based on the above findings, and includes (8) 2.
- Provides a hair treatment composition characterized by containing a hensyloxyethanolic polymer.

Hereinafter, the hair treatment composition of the present invention will be explained in detail.

Component (8) of the hair treatment composition of the present invention, 2-benzyloxyethanol, is used to promote hair swelling, and is preferably included in the composition at 0.2%. It is blended in an amount of 5 to 50% by weight, more preferably 1 to 30% by weight. If the amount is less than this, no swelling promotion effect will be observed. Further, even if more than this is added, no increase in the effect can be expected.

Further, the anionic polymer which is the component (B) of the hair treatment composition of the present invention may be a natural one or a synthetic one.

Specific examples of natural anionic polymers include xanthan gum, carrageenan, alginic acid, lithium, pectin, farcelan, gum arabic, gum ghatti, gum karaya, gum tragacanth, and agar powder.

Also included are carboxymethylcellulose, which is obtained by carboxymethylating cellulose.

Examples of synthetic anionic polymers include polymers obtained by polymerizing acidic vinyl monomers or salts thereof. The above-mentioned acidic vinyl monomer is a compound having an acidic group such as a carboxyl group, a sulfonic acid group, a phosphoric acid group, and a polymerizable vinyl group in one molecule, such as acrylic acid, methacrylic acid, etc. , crotonic acid,
Unsaturated basic acids such as vinylbenzoic acid, 2-acrylamido-2-methylpropanesulfonic acid, styrenesulfonic acid, vinylsulfonic acid, methacrylsulfonic acid, methacrylsulfonic acid, 3-methacrylicpropanesulfonic acid, and itacon Examples include unsaturated dibasic acids such as maleic acid and fumaric acid, and monoesters thereof. In addition, examples of the salts include sodium salts, potassium salts, ammonium salts, and the like.

In this polymerization, in addition to the acidic vinyl monomer, other vinyl monomers that can be copolymerized with the acidic vinyl monomer can also be copolymerized as optional components, but the proportion of the other vinyl monomers is , it is necessary to suppress the amount to 60 mol% or less based on the total monomers. Other vinyl monomers are monovinyl compounds that can be polymerized by the radical polymerization initiation side, such as acrylic esters such as methyl acrylate and ethyl acrylate, and methacrylic acid such as methyl methacrylate and ethyl methacrylate. Esters, styrene, α-
Styrene compounds such as methylstyrene, acrylamide,
Examples include methacrylamide, vinyl ether, vinyl acetate, and the like.

These anionic polymers can be used alone or in combination, and are preferably present in the composition in an amount of 0.01 to
10% by weight, more preferably 0. It is blended in an amount of 1 to 5% by weight. If the amount is less than this, it will not be possible to impart a perceptible and lasting conditioning effect. Moreover, even if more than this is added, no increase in the effect is observed.

Moreover, the hair treatment composition of the present invention comprises (C) acid or (D).
) It is more preferable to add an alkali and adjust its PL to a specific region in order to sufficiently swell the hair and obtain a better effect. That is, adding an acid as component (C) In this case, it is preferable to adjust the pH of the composition to 2 to 4, and when adding the alkali component (D), adjust 21-1 of the composition to 8.5 to 11. If the pH of the composition is less than 2 or more than 11, hair may be damaged. Regarding the swelling of hair by acids or alkalis, the research report of Bhatt et al.
handraBhat et al., J.S.
oc, Cosmet, Chem,, 32°39
3-405 (1981)). In this research report, hydrochloric acid is used as the acid and sodium hydroxide is used as the alkali. However, since hair itself is an ion exchanger, in the present invention, an organic acid is used as the acid, and ammonia or organic Preferably, amines are used.

Specific examples of the above 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,
Examples include fumaric acid and mandelic acid. Although it is not an organic acid, it is also preferable to use phosphoric acid.

Specific examples of the organic amines include monoethanolamine, jetanolamine, (-jetanolamine, aminohydroxymethylpropanediol, 2-amino-2-methyl-1-propanediol, 2-amino-2
-methyl-1,3-propanediol and the like.

In addition, it is also preferable to use basic amino acids such as arginine.

These acids or alkalis can be used alone or in combination, and are preferably added in an amount of 0.3 to 50% by weight, more preferably 0.5% by weight, so that the pH of the composition falls within the above range. ~30% by weight is blended. If the amount is less than this, there will be no swelling effect due to the ion exchange ability of the hair, and no increase in the effect will be observed even if more is added.

In the hair treatment composition of the present invention, the remainder other than the above-mentioned components (A), (B), and (C) or (D) is usually water.

Further, it is preferable that the hair treatment composition of the present invention contains an organic acid salt such as thorium salt or potassium salt, or an ammonium salt of an organic acid to form a buffer system.
