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, and more particularly to a hair cosmetic composition which has good spreadability and slipperiness on application, and has an efficient setting property. The present invention relates to a hair cosmetic composition which imparts gloss and gloss for a long time and does not give a sticky feeling.

[0002]

2. Description of the Related Art High molecular compounds have been used in the past for imparting settability to hair cosmetics, and such high molecular compounds have various ionic properties, for example, cationic compounds. There are polymer compounds such as anionic. In particular, cationic polymers are often used mainly in conditioning cosmetics for the purpose of improving the spread during application and the finished feel. However, there is a disadvantage that a strong setting property cannot be obtained while giving a good feeling. Therefore, when it is desired to give the hair cosmetic a high setting property, an anionic polymer compound or a zwitterionic polymer compound is usually used. However, such a type of polymer compound has a drawback in that although it has a high settability, it does not spread or slip during application and impairs the feeling of use. In order to improve these drawbacks, even if an attempt is made to obtain a high settability by blending a cationic polymer compound having good elongation and slipperiness at a high concentration, not only the effect is not sufficient, but also the viscosity of the undiluted solution increases and cosmetic There are problems such as changing the appearance of the material and generating a malodor derived from the polymer. Moreover, a cationic polymer compound or other cationic substance or an oil component is blended in a formulation composed of an anionic polymer compound or a zwitterionic polymer compound having a high settling property for the purpose of improving spread and slippage. However, there is a problem that a reaction occurs due to a difference in ionicity, precipitation occurs, the polymer compound is plasticized and stickiness occurs between application and drying, and the setting property of the core is deteriorated. Furthermore, when a small amount of a cationic polymer compound is added to prevent these problems, there is a problem that the effect of elongation and slippage cannot be obtained.

Silicone derivatives and polyhydric alcohols have hitherto been used to give hair cosmetics a moist feeling and gloss, but hair cosmetics containing a silicone derivative give moist feelings and gloss. However, it does not last long. Blending with polyhydric alcohol lasts for a long time, but gives a very unpleasant sticky feeling. Even if the setting polymer is used, the hair is glossed, but there is a drawback that a stiff feeling derived from the setting polymer is generated. That is, there has been no hair cosmetic which gives a moist feeling and gloss for a long time without giving a sticky feeling to the hair. Based on such a situation, various hair cosmetics have been studied for improvement, and one of them is the study of compounding a copolymer of vinylpyrrolidone and dialkylaminoalkylmethacrylate. Regarding the blending of this copolymer with a cosmetic for hair, JP-A-54-8730, JP-A-63-130517 and JP-A-63-1.
It is disclosed in Japanese Patent No. 30518. However, the hair setting and conditioning compositions disclosed in JP-A-54-8730 have excellent styling properties and conditioning properties, but have a poor effect of sustaining moisturizing feeling and gloss, and JP-A-63-130517 and The hair styling composition disclosed in JP-A-63-130518 improves the settability under high humidity and improves the combability, but on the other hand, it does not provide a moist feeling and a long-lasting gloss, and gives a sticky feeling. give. In any case, it is not a hair cosmetic that gives the hair a moist feeling and gloss for a long time without giving the hair a sticky feeling.

[0004]

In view of such circumstances, the present inventors have conducted earnest studies to obtain a hair cosmetic composition which has a high setting effect and is excellent in spreading and sliding during application. As a result, surprisingly, by blending the above copolymer and at least one compound selected from a cationic surfactant and a silicone oil, the setting efficiency is not impaired, and the composition is applied to the hair when applied to the hair. It has been found that a hair cosmetic composition which is smooth and has good sliding properties can be obtained.

Surprisingly, by blending the copolymer and at least one or more silicone derivatives selected from dimethyl silicone gum, organic silicone resin and modified silicone, without giving a sticky feeling to hair, A hair cosmetic having a long-lasting moisturizing feel and gloss is obtained, and further, at least one selected from quaternary ammonium salt type cationic surfactants, silicone oils, polyhydric alcohols and polyhydric alcohol derivatives. It has been found that, when combined, a hair cosmetic composition having a more moisturizing feel and a long-lasting luster can be obtained.
