Description

  The present invention relates to an aerosol cosmetic that gives a soft and light unit to hair, retains the finished hairstyle, and can re-style the original hairstyle with a hand comb or brush even if the hairstyle collapses.

  Conventional hair sprays generally fix hair by spraying a large amount of set polymer. However, in this method, since the polymer fixes the hair in a bundle shape, dissatisfaction occurs such that the finished hair is stiff and hard. Another problem is that once the fixing point is broken with a hand comb or brush after hair styling, the hairstyle collapses and cannot be restored. As a hair spray having no wrinkles, a hair spray in which the glass transition temperature of a hair fixing polymer is adjusted using a plasticizer has been proposed (see Patent Document 1). However, this also has insufficient adhesiveness of the film formed on the hair surface and cannot be restyled.

On the other hand, styling agents such as hair wax hold the hair with the adhesive strength of the oil, so that the hair will have a natural finish without solidifying, but the adhesive strength with the oil is compared to the fixing strength of the polymer for the set. It is very weak and it is difficult to keep the hairstyle you want. In addition, styling by the adhesive strength of oil can restore the hairstyle with a hand comb or brush, but cannot maintain a soft and natural finish. In addition, hair cosmetics that contain an adhesive component that is a combination of a polymer compound and an oil agent, and that have a certain level of adhesive strength, can impart a natural unit without solidifying the hair and have excellent hairstyle retention. Although it has been proposed (see Patent Document 2), there is a problem that this product has poor re-styling properties due to insufficient tackiness, and the finished hair does not have a soft finish.
