Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to the odor of a fragrance and the persistence of the odor, and also to the elongation and slipperiness when applied to hair, and also to the hair having sufficient smoothness, moistness and luster, Furthermore, it relates to a hair conditioning composition capable of imparting a proper firmness and elasticity.

[0002]

2. Description of the Related Art Hair conditioning compositions such as rinses, conditioners and treatments have hitherto been used to improve the feel of hair after shampooing. These compositions are conventionally blended with various conditioning components, for example, cationic surfactants and amidoamines, but since the improvement of the feel of flexibility and the like is insufficient, higher alcohols are used. It is used in combination (for example, Japanese Patent Laid-Open Nos. 5-271035 and 5-271036). Further, in order to compensate for insufficient smoothness of dried hair, many hair cosmetics contain a silicone derivative (for example, JP-A-58-21610).

On the other hand, many hair conditioning agents contain a fragrance, and it is required that the odor of the hair be used and the odor be maintained after the hair is used. However, with the hair conditioning agent, the fragrance is less likely to remain on the hair because of the form of washing off, and it is difficult to maintain the odor after use. In addition, a fragrance with a high vapor pressure has a good odor when used, but since a component with a higher vapor pressure is less likely to remain on the hair, the odor balance will change over time after use, and It was even more difficult to maintain an attractive scent in a balanced manner.

[0004]

Therefore, the present invention is excellent in the odor of fragrance and the durability of the odor, the elongation and the slipperiness when applied to the hair, and the sufficient smoothness on the hair after drying, An object of the present invention is to provide a hair conditioning agent composition which can give a moist feeling and gloss, and can impart appropriate firmness and elasticity to facilitate styling, and also has a mild action on the skin. .

[0005]

Means for Solving the Problems The present inventor has found that when a specific amidamine compound, a higher alcohol and a silicone having a specific viscosity are used in combination with an aroma component having a vapor pressure of a certain level or more, the odor of a fragrance is generated during use. It has been found that a hair conditioning agent composition which can maintain an attractive scent on the hair after use in a well-balanced manner and is excellent in the feel during use and the conditioning effect on the hair can be obtained.
