Description

  The present invention relates to a composition for hair, and more particularly to a composition for hair that is excellent in hair styling ability and hair styling sustainability, and has no stiff or sticky feeling.

  2. Description of the Related Art Conventionally, attempts have been made to add a polymer compound having a thickening / gelling action, such as carboxyvinyl polymer, to the hair composition in order to enhance hair styling power. For example, a gelled product of a crosslinked carboxyvinyl polymer, a transparent gel-like hair styling agent (see Patent Document 1) composed of a high molecular silicone compound and a dimethylpolysiloxane polyoxyalkylene copolymer, polyoxyethylene linear aliphatic ether, carboxy A foam hairdressing composition containing a vinyl polymer, ethyl alcohol and water (see Patent Document 2) has been proposed. However, these hair compositions improve hairdressing power to some extent by adding carboxyvinyl polymer, but satisfactory hairstyling power is not obtained.

  Attempts have also been made to use amphiphilic polymer compounds having thickening and gelling actions. For example, a hair cosmetic using a polyoxyethylene alkyl ether ester acrylic acid copolymer, powder and oil has been reported (see Patent Document 3). However, even with such a hair cosmetic, the hair styling power and the hair styling holding power are still not satisfactory.

For example, polyoxyethylene lauryl ether, polyoxyethylene cetyl ether, polyoxyethylene stearyl ether, polyoxy Polyoxyethylene alkyl ethers such as ethylene oleyl ether; polyethylene glycol fatty acid esters such as polyethylene glycol monooleate, polyethylene glycol monostearate, polyethylene glycol monolaurate; polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan monostearate, Oxidation of sorbitan fatty acid esters such as polyoxyethylene sorbitan monolaurate and polyoxyethylene sorbitan trioleate Guests can be exemplified alkylene condensate can polyoxyethylene hydrogenated castor oil, polyoxyethylene castor oil, polyoxyethylene lanolin, be mentioned mono lanolin polyoxyethylene sorbit and the like. Of these, polyoxyethylene alkyl ether is preferably used.

  (A) A component can be used individually by 1 type or in mixture of 2 or more types as appropriate. The content is not particularly limited as long as the effect of the present invention is exhibited, but it is preferably 0.1 to 20% by weight, more preferably 0.3 to 15% by weight in the composition. This is not preferable in any case because if the content is less than 0.1% by weight, the hair styling power is inferior, and if the content exceeds 20% by weight, a sticky feeling is imparted.

  The higher alcohol as the component (B) is not particularly limited as long as it is used as a raw material for cosmetics. For example, carbon such as lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, isostearyl alcohol, cetostearyl alcohol, oleyl alcohol, and behenyl alcohol. The higher alcohol of several 12-22 can be mentioned.

  (B) A component can be used individually by 1 type or in mixture of 2 or more types as appropriate. The content is not particularly limited as long as the effect of the present invention is exhibited, but it is preferably 0.1 to 20% by weight, more preferably 0.3 to 15% by weight in the composition. This is not preferable in any case because if the content is less than 0.1% by weight, the hair styling power is inferior, and if the content exceeds 20% by weight, a sticky feeling is imparted.
