Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition capable of preventing hair from becoming reddish and dry due to ultraviolet rays and imparting a proper moisturizing feeling to the hair.

[0002]

2. Description of the Related Art It has been conventionally said that ultraviolet rays cause problems such as reddening of hair and dullness. To prevent these, use hair spray, mousse, etc. without rinsing. A technique of blending a product with an ultraviolet absorber is known.

An ultraviolet absorber is added to a type of product such as rinse and treatment which is used by rinsing and rinsing,
If such a problem can be prevented, there is a possibility that the hair will be widely used regardless of hair length, hair quality, and hairstyle. However, in such a type of formulation to be used by rinsing, even if an ultraviolet absorber is blended, it may be rinsed off or unevenly adhered to hair, so that the effect is not exhibited. The current situation. Further, it has not been possible to obtain a sufficiently satisfactory hair cosmetic composition in which redness due to ultraviolet rays can be prevented but dryness is not improved.

[0004]

As described above, according to the prior art, when the rinse and the treatment are used regardless of the length, the hair quality and the hairstyle of the hair, the hair is prevented from being reddened by the ultraviolet rays and the roughness of the hair is prevented. The effect was insufficient, and a satisfactory result was not obtained.

In view of the above situation, the present invention prevents the reddishness and dryness caused by ultraviolet rays from spreading to the whole hair and adhering to the hair without being rinsed off, even if it is a type of formulation to be used after rinsing. It is an object to provide a hair cosmetic composition capable of imparting a moist feeling.

[0006]

In order to achieve the above object, the present invention provides (A) an ultraviolet absorber, (B) an alcohol or a condensate thereof having a total carbon number of 9 or more and an acid. A cosmetic for hair comprising the ester of (1), (C) water-soluble polymer, and (D) cationic surfactant and / or mono-N-long chain acyl basic amino acid lower alkyl ester salt To do.

[0007] In such a hair cosmetic composition, it is possible to obtain a hair cosmetic composition in which the effect of preventing reddening and dryness of the hair is further enhanced by combining and combining UV absorbents having different absorption regions. .
