Description

The present invention relates to a quick-drying hair cosmetic that imparts quick-drying property to hair and is also excellent in smoothness and moist feeling after drying, and a method for imparting quick-drying property to hair using the same.

In daily hair care, care with hair cosmetics such as conditioners, conditioners, and treatments is necessary to improve the feel of hair after shampooing. However, it takes time to dry the hair after rinsing, which can be a daily stress. In addition to shortening the time required to dry hair quickly, it is also expected to reduce heat damage to hair and reduce swell due to dry drying. Therefore, there is an increasing need for hair cosmetics that can impart quick-drying properties to hair.

As a method for imparting quick-drying property to hair, a method using polyalkyleneimine, an anionic surfactant and a cationic polymer (see Patent Document 1), or a method using a cationic polymer having a high charge density (see Patent Document 2). ), Those for the purpose of imparting quick-drying property by adding a high amount of ethanol (see Patent Document 3) and the like are known. In this way, the technology for imparting quick-drying properties to hair is advancing day by day, but the conditioning effect diminishes if quick-drying properties are greatly requested, so it was not sufficient in terms of both quick-drying properties and conditioning effects. ..
