DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition which imparts a non-sticky, supple feel and luster to hair and has re-shaping properties.

[0002]

2. Description of the Related Art Conventionally, oils such as silicone oils, ester oils, and hydrocarbon oils have been used in hair cosmetics by solubilizing, emulsifying, and dissolving them for the purpose of giving the hair a supple feel and excellent combability. Have been. In particular, silicone oil is excellent in non-stickiness and has been widely used in recent years. However, with oils represented by silicone oil, the ability to set hair is poor and insufficient.

[0003] In addition, high molecular compounds having various film-forming properties are used in hair styling cosmetics for the purpose of setting hair. However, although the polymer compound is excellent in setting properties, once the film is broken, the hairstyle remains broken,
It does not have re-styling properties. In addition, there is a drawback that it is stiff and sticky during drying and under high humidity.

[0004]

DISCLOSURE OF THE INVENTION In view of such circumstances, the present inventors have provided hair with a non-sticky, supple feel and luster,
As a result of diligent studies aimed at providing a hair cosmetic having re-styling properties, the following general formula (1)

DESCRIPTION OF THE PREFERRED EMBODIMENTS The silicone-modified polymer used in the present invention is a reaction product of an amino group-containing polysiloxane represented by the above formula (1) and an anion group-containing polymer.

The anion group-containing polymer used in the production of the silicone-modified polymer is not particularly limited as long as the polymer contains an anion group. For example, a polymethyl vinyl ether / maleic acid half ester copolymer, vinyl acetate / Crotonic acid copolymer, alkyl acrylate / alkyl methacrylate copolymer, dimethylhydantoin-formaldehyde acrylate resin, vinyl acetate / crotonic acid / vinyl neodecanoate copolymer, t-
Butyl acrylate / ethyl acrylate / methacrylic acid copolymer, alkyl acrylate / alkyl methacrylate / diacetone acrylamide / methacrylic acid copolymer,
Vinyl pyrrolidone / vinyl acetate / vinyl propionate copolymer, vinyl acetate / crotonic acid / vinyl pyrrolidone copolymer, vinyl pyrrolidone / acrylate copolymer, acrylate / acrylamide copolymer,
Examples include anionic polymers such as vinyl acetate / butyl maleate / isobornyl acrylate copolymer, and amphoteric polymers such as octyl acrylamide / hydroxypropyl acrylate / butylaminoethyl methacrylate copolymer. Group-containing polymers are desirable.

In the silicone-modified polymer used in the present invention, 20 to 5,000 parts by mass of an anion group-containing polymer is reacted with 100 parts by mass of an amino group-containing polysiloxane. If the amount of the anion group-containing polymer is less than 20 parts by mass with respect to 100 parts by mass of the amino group-containing siloxane, the setting property becomes insufficient, which is undesirable.
If the amount is more than 00 parts by mass, gloss, flexibility and the like become insufficient, which is not desirable.

The reaction product of the amino group-containing polysiloxane and the anion group-containing polymer is an alkaline substance such as 2-amino-2-methylpropanol, 2-amino-
It is desirable to neutralize with 2-methyl-1,3-propanediol or triisopropanolamine, diisopropanolamine, triethanolamine, potassium hydroxide, sodium hydroxide or the like before use. Further, it may be neutralized during the production of the present composition. In that case, the neutralization rate is 60 ~
It is preferable to neutralize to 150%. The silicone-modified polymer of the present invention can be easily synthesized by the method described in JP-A-4-43804. It is also commercially available from Nippon Unicar under the trade name of Silicon FZ-3148.

The compounding amount is 0.05 to 1
5 mass% is preferable, and 0.1 to 10 mass% is more preferable. If the amount is less than 0.05% by mass, the non-stickiness and the setting property tend to be insufficient. Further, when the amount is more than 15% by mass, the washing-off during hair washing tends to be poor.

The structure of the nonionic surfactant used in the present invention is not particularly limited as long as it has an HLB of less than 15, and examples thereof include glycerin fatty acid ester, polyglycerin fatty acid ester, propylene glycol fatty acid ester, and pentaerythritol fatty acid ester. , Polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbite fatty acid ester, polyoxyethylene glyceryl fatty acid ester, polyethylene glycol fatty acid ester, polyoxyalkylene alkyl ether,

The amount of the nonionic surfactant having an HLB of less than 15 is preferably 0.03 to 10% by mass.
0.1-5 mass% is more preferable. When the amount is less than 0.03% by mass, it is difficult to stably mix the oil agent.
If it exceeds 10% by mass, stickiness tends to be felt. Further, it is difficult to stably blend an oil agent with a nonionic surfactant having an HLB of 15 or more. More preferably, the nonionic surfactant has an HLB of 8 or more.

The oils used in the present invention include natural oils such as soybean oil, jojoba oil, avocado oil, almond oil, olive oil, cocoa butter, sesame oil, persic oil, castor oil, coconut oil, mink oil, beef tallow, lard, etc. Fats and oils, hardened oils and fats obtained by hydrogenating these natural fats and oils, carnauba wax, whale wax, candelilla wax, beeswax, lanolin, and other waxes, liquid paraffin, vaseline, paraffin, microcrystalline wax, ceresin, squalane , Pristane and other hydrocarbons, higher fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid, linoleic acid, linolenic acid, lanolinic acid, isostearic acid, cetyl octanoate, myristyl lactate, lactic acid Cetyl, isopropyl myristate,

Silicones such as fluorine-modified silicone, cyclic silicone, alkyl-modified silicone, and fluorine-modified silicone are exemplified.

The amount of the oil agent is preferably from 0.1 to 20% by mass, more preferably from 0.5 to 10% by mass. If the compounding amount of the oil agent is less than 0.1% by mass, it may lack flexibility and may have poor re-shaping properties. 20% by mass
It is not preferable that the amount is more than 0.1% because stickiness is felt. The above oil agents can be used alone or in combination of two or more.

The hair cosmetic composition of the present invention may contain, in addition to the above essential components, a lower alcohol, a thickener, a propellant, water, a preservative, a chelating agent, an antioxidant, as long as the effects of the present invention are not impaired.
