Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair styling composition, and more particularly to a hair styling composition which suppresses dryness and has good hair slipperiness.

[0002]

2. Description of the Related Art In general, when styling a hairstyle, a hair dryer is used to blow the hair so that the damp hair and the dry hair can be forced. At this time, the moisture of the hair is excessively volatilized by the heat of the dryer, which gives a feeling of damage such as dryness, and actually causes split ends and broken hair. Therefore, a hair styling composition containing an oil, silicone or the like is used for the purpose of suppressing a feeling of damage such as dryness and further protecting the hair and improving the touch. A hair styling composition containing such an ingredient is used. Has not yet been fully effective.

The alkylene oxide containing ethylene oxide which is subjected to addition polymerization with an organic compound having two active hydrogen groups is ethylene oxide alone or an alkylene oxide containing ethylene oxide. Alkylene oxides other than ethylene oxide have 3 to 30 carbon atoms, and for example, propylene oxide, butylene oxide, styrene oxide, α-olefin epoxide or glycidyl ethers can be used.

Here, the content of the alkylene oxide having 3 to 30 carbon atoms is arbitrary, but the content of ethylene oxide is preferably 70 to 100% by weight based on the total alkylene oxide.
