Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair setting composition, and more particularly, to a hair setting composition such as a hair setting composition, a styling composition, and a hairdressing composition, which has both excellent set holding power and good feel. About things.

[0002]

2. Description of the Related Art Hair setting agents which have been widely used in the past are obtained by dissolving a film-forming polymer compound in water, a lower alcohol or a mixed solvent thereof. The polymer compound blended here has the effect of fixing the hairs together and holding the set, but the ones that have been used conventionally have stickiness in the process of applying to the hair and drying it. It wasn't smooth. In order to solve such disadvantages, attempts have been made to improve the feel in use by adding oils and fats for cosmetics, surfactants, and the like to the polymer compound. However, a hair setting agent having both sufficiently satisfactory set holding power and use feeling has not yet been obtained.

[0003] In recent years, a hair treatment agent containing an amphoteric polymer compound and a cationic polymer (Japanese Patent Publication No. 2-44446).
And Japanese Patent Publication No. 3-14805) and a hair treatment agent comprising an amphoteric polymer compound and an anionic polymer (Japanese Patent Publication No. 3-21524). However, these treating agents are not satisfactory in terms of non-stickiness and smoothness from application to drying and also have a feeling of finished hair which is unsatisfactory.

[0004] Therefore, the fixing force between the hairs is sufficient,
It is desired to develop a hair setting agent composition in which a formed film is rich in elasticity, does not rub, has excellent style holding power, and is non-greasy, smooth, and easy to give in the process from application to drying. Was.

[0005]

Under such circumstances, the present inventors have conducted intensive studies and as a result, have found that the following components (A) and (B) are used in combination, and a specific pH range is obtained by using an inorganic acid. The present inventors have found that a hair setting composition having both excellent set holding power and good feel can be obtained, and the present invention has been completed.

That is, the present invention provides the following component (A):
(B) and (C), and the pH of the whole composition is 5 to 5.
9 is a hair setting agent composition.

(A) A copolymer having a vinyl alcohol unit and a vinylamine unit represented by the following structural formula (1).

[0008]

(Wherein, m is a number such that 0 to 5 mol%, n is a number such that 50 to 99 mol%, and x is 0 to 3 mol%.
The number which becomes 0 mol%, and y is a number which becomes 1 to 50 mol%. However, the respective structural units are arranged in an arbitrary order. )

(B) One or more ester oils selected from diester oils, triester oils, tetraester oils, full ester oils and sesquiester oils which are liquid at room temperature. (C) an inorganic acid or an organic acid.

Hereinafter, the configuration of the present invention will be described in detail. The vinyl alcohol / vinylamine copolymer of the component (A) used in the present invention can be produced by the following production steps. (A) A vinyl acetate monomer and an N-vinylformamide monomer are continuously supplied into a reaction vessel. (B) Copolymerizing vinyl acetate and N-vinylformamide to form poly (vinyl acetate) -co-poly (N-vinylformamide) [PVAc / PNVF] in the reaction mixture. (C) The reaction mixture containing PVAc / PNVF is continuously taken out of the reaction vessel. (D) Hydrolysis of the acetate function of PVAc / PNVF in a medium of methanol to form a vinyl alcohol copolymer as a gel swollen with methanol and methyl acetate. (E) grinding the gel to obtain a particulate copolymer product, optionally rinsing with methanol. (F) hydrolyzing the copolymer particles with an acid or a base in the form of a slurry in a mixture of isopropyl alcohol and water;
Obtain VOH / PVAm particles. And optionally but preferably further: (g) washing the particulate PVOH / PVAm with methanol to remove soluble salts and by-products, and removing solvent from the copolymer product, especially by vacuum or thermal stripping. Is removed.

Through the above-mentioned production steps, a modified polyvinyl alcohol composition comprising a copolymer of vinyl alcohol having the above general formula (1), vinyl acetate and / or vinyl formamide as optional components, and vinylamine is provided. You.

Details of the method for producing such a vinyl alcohol / vinyl amine copolymer are described in, for example, Japanese Patent Publication No. 6-517.
No. 41 publication.

The blending amount of the vinyl alcohol / vinylamine copolymer used in the present invention is sufficient for good feeling such as set holding power and non-stickiness, which are the objects of the present invention, and the amount of flaking (polymer film) As a result of examining the range in which no peeling or powdering occurs, the content is preferably 0.1 to 10.0% by weight, more preferably 0.5 to 5.0%, based on the total amount of the hair setting composition. % By weight. If the amount of the vinyl alcohol / vinylamine copolymer is less than 0.1% by weight, it is difficult to obtain the effects of the present invention. If the amount exceeds 10.0% by weight, flaking tends to occur.

Next, the ester oil which is liquid at room temperature of the component (B) used in the present invention will be described. Examples of the ester oil which is liquid at room temperature used in the present invention are as follows. As diester oil, di-2 succinic acid
-Ethylhexyl, neopentyl glycol di-2-ethylhexanoate, neopentyl glycol dicaprate, di-2-heptylundecyl adipate, diisostearyl malate, polyglyceryl diisostearate, polyglyceryl triisostearate and the like.

Examples of the sesquiester oil include sorbitan sesquioleate. Particularly preferred among these ester oils are:
It is a diester oil, and di-2-ethylhexyl succinate is particularly preferred.

The amount of the ester oil which is liquid at normal temperature in the present invention is sufficient for the object of the present invention, such as set holding power and non-stickiness, and the range in which oiliness and weight do not occur is examined. As a result, based on the total amount of the hair setting composition, it is preferably 0.1 to 10.0% by weight, more preferably 0.5 to 8.0% by weight.

Next, the inorganic acid of the component (C) used in the present invention will be described. The inorganic acid used in the present invention is p
It is used as an H adjuster, such as hydrochloric acid, phosphoric acid, lactic acid, citric acid, and nitric acid. One or more of these are arbitrarily selected so that the pH of the entire composition is 5 to 9. Adjusted.
