  By the way, some users may ask hair cosmetics for functions and effects other than those required to have a refreshing feeling and good elongation during use, as well as excellent cosmetic aroma, appearance and stability. is there. As an example of the effect, after using a spray, there are cases where the finger's finger, hair, and gloss are good, and a proposal of a spray that can realize these is desired. Moreover, since it can expect reduction of the influence on the hair by an ultraviolet-ray if it is the spray which accommodated the hair cosmetics which mix | blended the raw material which has the property to absorb an ultraviolet-ray, such a spray is also desired.

  SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a spray that contains a hair cosmetic containing a raw material having an ultraviolet absorption property, and that has good texture, smoothness and glossiness.

  As a result of studying hair cosmetics for spraying that have a high volatility and a low amount of volatile cyclic silicone with a low surface tension, the present inventors have determined that a specific raw material having the property of absorbing ultraviolet B waves is used as a hair cosmetic. When blended into the hair, the smoothness of the hair is improved, and if a specific material having the property of absorbing ultraviolet A waves is further blended, the hair gloss is improved while suppressing the deterioration of the hair mass, The present invention has been completed.

  That is, the spray according to the present invention accommodated a hair cosmetic containing 2- (4-diethylamino-2-hydroxybenzoyl) benzoic acid hexyl ester, paramethoxycinnamate 2-ethylhexyl, and volatile cyclic silicone. It is characterized by that.
