Description

The present invention relates to a hair rinse composition, and more particularly to softening the hair, smoothing the surface of the hair, improving combing properties and imparting gloss, as well as to letting the hair pass even in a dry environment. It is related with the hair rinse composition excellent in the effect which hold | suppresses and the unit of hair lasts for a long time.

Hair rinse compositions having a so-called rinse effect that imparts smoothness and luster to hair and improves combing are generally sold under the names of hair rinses, hair treatments, hair packs, and the like. These hair rinse compositions are usually blended with a cationic surfactant, which is known to give the above-mentioned rinse effect when adsorbed on the hair. Furthermore, for the purpose of improving the feeling after use such as smoothness, gloss and moist feeling, for example, oils such as higher alcohol, glycerin fatty acid ester, higher fatty acid, liquid paraffin and ester oil are added. Various feels are adjusted by adjustment. However, it cannot be said that these have sufficient effects to suppress the flexibility, smoothness and roughness of the hair, and it is known that the stimulation to the hair and scalp is not sufficiently reduced. Therefore, development of various components and their blending have been attempted.

In recent years, it has been found that amidoamine compounds impart smoothness and flexibility to hair, and hair cosmetics containing amidoamine compounds or salts thereof have been proposed. For example, amidoamine compounds and N-long chain acyl basic amino acids have been proposed. By combining a lower alkyl ester salt and a higher alcohol, a composition (for example, see Patent Document 1) imparted with a smooth feeling, moist feeling, and flexibility, or a combination of an amidoamine compound and a specific glycol, a smooth feel Hair cosmetics that impart flexibility (for example, see Patent Document 2) have been proposed. In addition, a hair cosmetic that contains a specific amidoamine and an aliphatic alcohol and imparts a smooth feeling and a moist feeling has been proposed (see, for example, Patent Document 3). All of these techniques have been improved as hair rinsing compositions, but only the surface properties of the hair are modified, and the hair moisturizing properties are reduced the next day after washing. Has a problem that it feels uncomfortable due to the dryness and cannot be set well, especially in the low humidity environment of winter, such as the occurrence of rustling and the effect of smoothness and moist feeling do not last It was not satisfactory.
