Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition, more specifically, it has excellent set-retaining properties, and can impart a good feel such as smoothness and flexibility to the hair after setting,
The present invention relates to a hair cosmetic that can prevent hair damage due to brushing or the like.

[0002]

2. Description of the Related Art Conventionally, various hair cosmetics such as set lotions, hair sprays, hair mists and hair foams have been used for the purpose of making hairstyles easier and making hairstyles last longer. Cosmetics have been produced by dissolving a polymer compound for fixing hair (hereinafter referred to as a hair setting polymer) in a suitable solvent such as water, a lower alcohol or a mixed solvent of water-lower alcohol. And, it is a hair lotion that uses the obtained solution as it is, and a hair mist that is used by atomizing the solution with a pump or the like is a liquefied gas suitable for the above solution as a propellant. What is mixed and used as an aerosol is a hair spray, and what is made into the form injected as a foam is a hair foam. Further, in recent years, along with the diversification and individualization of hairstyles, there has been a demand for hair-type cosmetics containing a large amount of a hair-setting polymer to harden the hair so that the hair can be set more firmly.

[0003]

In order to obtain a desired hair setting by adding a large amount of a hair setting polymer to a hair cosmetic composition, there are the following problems. That is, the hair-setting polymer is a film-forming resin, which gives a specific stickiness when applied to hair, and when used,
It will be very uncomfortable. Further, after forming the coating film, the feeling such as stiffness and roughness was deteriorated. Also, the oil agent used to improve the feel is
The setting power was reduced, and after drying, it became a discomfort and became uncomfortable. Therefore, it is desired to develop a hair cosmetic composition that has excellent setting power even when an oil agent is used to give an appropriate oil content to the hair, and that the hair feels good after setting and does not damage the hair. It was rare.

To address this problem, for example, an aerosol mousse containing a hair-setting polymer and a high-molecular-weight silicone substance, which has excellent settability and provides ease of combing, has been proposed (for example, JP-A-62-48615). ), A hair cosmetic containing a water-soluble polymer, glycerin and a polyoxyalkylene-modified organopolysiloxane has been proposed (for example, JP-A-1-163113). However, it is difficult to obtain the desired effects of the present invention with these hair cosmetics. For example, dimethylpolysiloxane has poor compatibility with hair-setting polymers and poor affinity with hair. For this reason, the sticky feeling after drying is great and strong setting force cannot be expected. In addition, phenyl-modified silicone is
Although it has a good affinity with hair-setting polymers, the polymer feels stiff to the touch and has little effect on preventing hair damage. Further, in the invention disclosed in JP-A-1-163113, since a large amount of glycerin is contained, the film covering hair is very soft and easily peeled off. For this reason, strong setting power cannot be obtained,
The effect of preventing hair damage cannot be expected.

[0005]

Under these circumstances, the inventors of the present invention have conducted extensive studies and as a result, as a result, an anionic polymer was used as a film-forming hair-setting polymer, and a specific polyether-modified silicone was further added. The present invention has been completed based on the finding that, in addition to good setting, a hair cosmetic having good compatibility with an oil agent and having excellent feel of the hair after setting and an effect of preventing damage can be obtained.

That is, the present invention provides (a) a hair-setting polymer comprising an anionic polymer, (b) the following (A), (B),
The present invention provides a hair cosmetic containing one or more polyoxyorganopolysiloxanes selected from (C), (D) and (E).

No. 07) is proposed. However, cationic polymers and nonionic polymers generally have high hygroscopicity under high humidity, resulting in a marked decrease in setting force. For this reason, it is difficult to obtain the intended effect even when combined with a polyether-modified silicone. Further, an amphoteric polymer is generally hard and brittle, so that when used as a styling agent, there is a problem that the set is easily broken. As described above, it is difficult to achieve the object of the present invention by any of the above-described conventionally known techniques.
