Field of the Invention The present invention relates to a set-holding hair cosmetic, and more particularly, to a hair having a smooth feel, excellent combability, a supple finish, a soft touch and the like. The present invention relates to a set-holding hair cosmetic which imparts excellent gloss and excellent gloss.

[0002]

2. Description of the Related Art Conventionally, as a hair cosmetic such as a set lotion or a hair spray for keeping a hairstyle in a fixed shape for a long time, various compositions mainly comprising a film-forming resin for holding the hair have been used. Proposed. Especially,

[0003] However, the set-holding hair cosmetics according to the above-mentioned patent application are excellent in various properties, but cannot be said to have sufficient gloss and gloss, which have been particularly required by recent fashion. . For this reason, there is a demand for a set-holding hair cosmetic that can impart sufficient gloss and luster.

[0004]

SUMMARY OF THE INVENTION The present invention overcomes the above-mentioned drawbacks of the prior art, namely, a smooth feel to hair, excellent combability, a supple finish,
It is an object of the present invention to provide a set-holding hair cosmetic that imparts a soft touch and good set holding properties and has excellent storage stability as well as sufficient gloss and luster.

[0005]

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, by introducing a phenyl group-containing group into a specific amino group or ammonium group-containing polysiloxane, very good results have been obtained. The present inventors have found that the above results have been obtained and that the stability has been significantly improved, and further studies have been made to complete the present invention.

That is, the present invention is characterized in that it contains a composite polymer obtained by reacting a polysiloxane having at least one amino group or ammonium group and at least one phenyl group-containing group with an anionic polymer. The present invention relates to a set-holding hair cosmetic.

The present invention also provides the following formula: Wherein R ¹ is independently of each other C ¹ -C 18
Represents an alkyl group, a hydroxyl group, an alkoxy group having 1 to 5 carbon atoms or a trimethylsiloxy group, and Q ¹ represents the following formula: -R ³ X ｛R ³ represents a direct bond or an alkylene group having 2 to 6 carbon atoms. And X is of the formula:-(NR

Are independently of each other hydrogen or C 1 -C 4
R ⁵ represents an alkylene group having 2 to 6 carbon atoms, R ⁶ represents an alkyl group having 1 to 4 carbon atoms, and A ⁻ represents Cl ⁻ , Br ⁻ , I ⁻ or CO 2.
O ^- to represent, and e represents a group represented by 0 represents an to groups selected from the group consisting of an integer of 6)},
Q ² represents a phenyl group-containing group, R ² independently of one another, has the same meaning as defined for R ¹ , Q ¹ or Q ² above, and x, y and z are each an integer of 0 or more. And 0 ≦ x + y + z ≦ 2000, provided that when y = 0, at least one of R ² is Q ¹ and z
And in the case of = 0, at least one of R ² is Q ² ], and a composite polymer obtained by reacting a polysiloxane represented by the formula (I) with an anionic polymer. About charges.

[0008] In any of the set-holding hair cosmetics of the present invention, it is preferable that the composite polymer is neutralized with an alkaline compound so as to have a neutralization ratio of 60 to 150%.

The radical R ¹ in the above formula has 1 to 1 carbon atoms.
8 alkyl groups such as methyl group, ethyl group, propyl group, butyl group, octyl group, dodecyl group and the like, preferably methyl group or ethyl group, particularly preferably methyl group, or trimethylsiloxy group [- OSi
(CH ₃ ) ₃ ]. Further, the groups R ¹ in the molecule may be the same or different.

The group Q ¹ in the above formula is -R ³ X as described above.
And specific examples include the following groups:

The group Q ² in the above formula is a phenyl group-containing group, for example, the following formula: —R ³ A (where R ³ has the same meaning as defined above, ie, a direct bond or the number of carbon atoms. 2 to 6 alkylene groups, especially an ethylene group, and A is a group represented by an unsubstituted or alkyl group, particularly a phenyl group substituted by a methyl group; , -Ph), a tolyl group [-Ph (CH ₃ )], a xylyl group [-Ph (C

May be at the o, m- or p-position relative to the bond or free bond to ³ ;
It may be at the m- or p-position and may have any further substituents, even if it has more substituents. The groups R ² in the above formula independently represent the same meaning as defined for any of R ¹ , Q ¹ or Q ² above, but a part or all of which is a hydroxyl group or an alkoxy group. A set-holding hair cosmetic using siloxane has better set-holding properties, but may have slightly poor storage stability.

X, y and z in the above formula are integers in the above range. When the ratio is out of this range, the composite polymer which is a reaction product with the anionic polymer is liable to gel, making it difficult to prepare a stable set-holding hair cosmetic, and imparting gloss and luster to the hair. The characteristics deteriorate.

The anionic polymer used in the present invention includes polyvinyl pyrrolidone, polyvinyl pyrrolidone vinyl acetate copolymer, copolymer of polymethyl vinyl ether and ethyl and butyl monoester of maleic acid, carboxylated polyvinyl acetate copolymer, vinyl acetate And crotonic acid, a copolymer of an alkyl acrylate and an alkyl methacrylate, a dimethylhydantoinformaldehyde resin, and the like, and a carboxyl group-containing polymer is particularly desirable.

Next, a method for producing a composite polymer used in the set-holding hair cosmetic of the present invention will be schematically described. First, 20 to 5000 parts by weight of the anionic polymer is reacted with 100 parts by weight of the polysiloxane. If the amount of the polysiloxane is less than the above range, the setting property may be insufficient, and if the amount of the polysiloxane is more than the above range, the gloss and the flexibility may be insufficient. Next, the reaction product (composite polymer)
May be neutralized with an alkaline compound so as to have a neutralization ratio of 60 to 150%, whereby the storage stability can be further improved. If the neutralization ratio is less than 60%, the water solubility of the product (composite polymer) may be insufficient, and if it exceeds 150%, the hair set retention by the product (composite polymer) may be insufficient. In some cases, the tackiness may decrease and the tackiness may increase, which is not preferred. The alkaline compound used for neutralization is not particularly limited, but 2-amino-2-methylpropanol, 2-amino-2-methyl-1,3-propanediol or triisopropanolamine can be used.

The set-holding hair cosmetic composition of the present invention comprises the above-mentioned composite polymer as a main component, and uses a lower alcohol or a mixture of water and a lower alcohol as a carrier to form a spray, a mist or the like. It can be a hair cosmetic in a liquid or foamy (mousse) form.

The set-holding hair cosmetic of the present invention may contain additives which are added to ordinary hair cosmetics to such an extent that the effects of the present invention are not impaired. For example, the following additives outside the range of the above-mentioned polysiloxane of the present invention may be blended in appropriate amounts: silicone compounds of various shapes (eg, oil, resin, gum, rubber, powder, etc.) (eg, dimethylpolysiloxane, dimethylmethyl) Phenylpolysiloxane, dimethyldiphenylpolysiloxane, amino-modified dimethylpolysiloxane, epoxy-modified dimethylpolysiloxane, polyether-modified dimethylpolysiloxane, polycaprolactone dimethylpolysiloxane, α
