Abstract

PROBLEM TO BE SOLVED: To obtain a hair treating composition capable of arranging hair style in a natural feeling and keeping the hair style for a long period of time without giving oily feeling, slippery feeling and sticky feeling to the hair. SOLUTION: This hair treating composition contains a polyvinyl alcohol denatured with a cationic group. Preferably, the denatured degree of the polyvinyl alcohol with the cationic group is >=0.2mol%. The hair treating composition using the polyvinyl alcohol denatured with the cationic group has high keeping power of hair setting without giving oily feeling, slippery feeling and sticky feeling to hair in contrast to a hair treating composition not denatured or denatured with the other compound. The hair treating composition using the polyvinyl alcohol denatured with the cationic group is hardly plasticized in a high humidity and has a high set keeping power in raining weather, furthermore exhibits no stiffness or flaking of hair, thus the hair can be set in a natural feeling. The hair treating composition can also be prepared as the forms of a hair foam, a hair splay, a hair set mist, a hair set gel, a curler lotion, a set lotion and a blow lotion, etc.

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 gathering a hairstyle with a natural texture and keeping it for a long time without feeling oily.

[0002]

2. Description of the Related Art Currently used hair styling agents are roughly classified into the following two types according to their functions. 1. A device for fixing hair to each other by fixing hair to each other to hold the hair style. In this case, a polymer that mainly forms a film having high film strength is used as a hair styling agent. 2. A hair style that does not stick hair to each other and creates a smooth and natural texture. In this case, the hair styling agent is mainly an adhesive resin such as polymer silicone, hydrocarbon oil, ester oil, silicone oil. Oil agents such as oil and fat compounds are used.

[0003]

Among these two types of hair styling agents, the former is superior in the set holding power, but the polymer film gives a hard feel and the hair is not bundled to form a hair. The problem is that it looks natural.

On the other hand, the latter is soft to the touch because the hair does not form a hard bundle and is natural in appearance. However, the set holding power is inferior, and a large amount of adhesive resin or oily agent is required in order to sufficiently gather hair. For this reason, when trying to put together the hair sufficiently, it is necessary to apply a large amount of a hair styling agent to the hair, and therefore, the oily feeling when touching the hair becomes strong, and further, the transfer is difficult. It causes problems such as sliminess and stickiness.

The present invention is intended to solve the problems of the prior art as described above, and allows the hairstyle to be smoothly and naturally textured without giving the hair an oily feel, a slimy feel, and a sticky feel. And it aims at providing the hair treatment composition which can hold | maintain it for a long time.

[0006]

Means for Solving the Problems The present inventors have found that a polyvinyl group modified with a cationic group gives a hairstyle a smooth and natural texture without giving the hair an oily feeling, a slimy feeling, or a sticky feeling. Can be put together,
Furthermore, they have found that the cohesion of hairstyles is maintained for a long time even under high humidity, and have completed the present invention.

[0007] That is, the present invention provides a hair treatment composition characterized by containing polyvinyl alcohol modified with a cationic group.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

The hair treatment composition of the present invention contains polyvinyl alcohol modified with a cationic group. Thereby, the set holding power of hair is greatly improved as compared with the case where polyvinyl alcohol which is not modified with an ionic group or polyvinyl alcohol which is modified with an anionic group or a zwitterionic group is contained. Therefore, even when the hair is set with high holding power, the hair does not feel oily, slimy or sticky.

The polyvinyl alcohol modified with this cationic group is difficult to plasticize under high humidity. Therefore, the holding power of the set under high humidity such as rain is also greatly improved.

Further, the polyvinyl alcohol modified with a cationic group does not make the hair stiff and does not cause flaking. Therefore, the hair treatment composition of the present invention makes it possible to form a natural texture set on the hair.

The polyvinyl alcohol modified with a cationic group used in the present invention can be obtained, for example, as a block polymer or a random polymer of polyvinyl alcohol and a monomer having a cationic group.

Examples of the monomer having a cationic group for forming such a polymer include the following acrylamide, methacrylamide, crotonylamide, acrylic acid, methacrylic acid, and crotonic acid. There may be mentioned each monomer of the system.

[Chemical 6] (In the formula, R ¹ , R ² and R ³ each represent methyl, ethyl or propyl. These may be the same or different. P is an integer of 1 to 5.)

Further, in this case, the degree of modification with the cationic group is preferably 0.2 mol% or more as a ratio of the unit having the cationic group to the total unit of the vinyl alcohol unit and the unit having the cationic group, It is more preferably 0.5 to 50 mol%, still more preferably 3 to 8 mol%. If the degree of modification is too low, a strong slimy feel and a sticky feel are generated immediately after application to the hair, which is not preferable. Further, if the degree of modification is too high, the cohesiveness of the hairstyle is reduced, which is not preferable.

The degree of saponification of the polyvinyl alcohol modified with a cationic group is usually preferably 50% or more, more preferably 75% or more. If the degree of saponification is too low, the pungent odor (odor of acetic acid) becomes strong, which is not preferable.

The degree of polymerization of polyvinyl alcohol modified with a cationic group is usually preferably 500 or more.
If the degree of polymerization is too low, the cohesiveness of the hairstyle under high humidity decreases, which is not preferable.

The hair treatment composition of the present invention may contain various components as required. For example, in order to further improve the cohesiveness of the hairstyle, a resin component such as polyethylene glycol or polymer silicone, an oil agent such as hydrocarbon, ester oil or silicone oil, or an oil / fat component may be contained. Further, for the purpose of solubilizing or emulsifying the hair treatment composition, a solvent, an anion, a cation,
It may contain a surfactant such as nonionic, and further, thickener, chelating agent, pearling agent, fragrance, dye,
Additives usually used in cosmetics such as an ultraviolet absorber, a foaming agent and a propellant may be appropriately contained.

There is no particular limitation on the manufacturing method and dosage form of the hair treatment composition of the present invention. For example, hair foam, hair spray, hair set mist, hair set gel, curler lotion, set lotion, blow lotion and the like can be used.
