However, in the technique using a cationic polymer, if a large amount of blending is desired to exhibit smoothness or flexibility, the adsorption of hair by the cationic polymer may be rough. Further, in the technique using a polyfluorene oxide derivative, there is a case where the polyoxonium derivative itself is not easily dissolved in the case of handling problems in the case of general oil production. Further, in the technique of using an acrylic polymer having a structure similar to a living body, there is a case where the hair is excellent in repairing or the like, but the effect is not sufficient.

The ingredients that contribute to the effects of persistence are reviewed. In reviewing various components, it is considered that by using an oily component, the skin or hair can be covered with the polymer to improve the sustainability of the effect. As a result of intensive review by the inventors of the present invention, it was found that a specific fatty acid dextrin enhances the persistence. Further, it has been newly discovered that the present invention can be attained by reducing the stickiness of the fatty acid dextrin by making the oil-in-water emulsified composition containing the above. Further, it has been found that when the present invention is used as a cosmetic for hair, it is particularly useful to use a cationic surfactant for emulsification. Further, it has been found that by containing an amino acid and an amino acid derivative, the durability can be further remarkably improved in all the effects of the smoothness, non-stickiness, and moisturizing feeling which are the effects of the present invention.
