DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic which gives a natural luster to the hair without causing a feeling of creaking.

[0002]

2. Description of the Related Art In order to impart gloss to hair, oil agents such as higher alcohols and liquid oils, and high molecular weight silicones have been applied to hair.

[0003]

However, the above oil agent is
There are drawbacks such as a glaring and unnatural feeling and a sticky hair feel. In addition, the above-mentioned silicone can give gloss to hair, but the feeling is slippery and the natural feeling is impaired,
In addition, there is a drawback that the coating is peeled off by a physical treatment such as brushing and the like, and the appearance is impaired.

Therefore, the present inventors have previously proposed a hair cosmetic using a dialkylene glycol monoalkyl ether as a hair cosmetic that gives a natural gloss to hair (Japanese Patent Application No. 3-334785). In this hair cosmetic composition, improvement in squeaky feeling when the hair is soaked has been desired.

[0005] Accordingly, an object of the present invention is to provide a hair cosmetic that gives natural shine without causing squeaky feeling to hair.

[0006]

According to the present invention, there are provided (a) a polyalkylene glycol monoalkyl ether represented by the following general formula (I) of the following [formula 2] (same as [formula 1]) and (b) ultraviolet light. The above object has been achieved by providing a hair cosmetic containing an absorbent.
