Description

  The present invention relates to a powder hairdressing agent.

  Emulsified compositions containing oils such as solid oil and liquid oil, typified by hair wax, are widely used as hair styling agents capable of re-shaping hair once prepared. However, since a large amount of oil is blended in the hair wax, there is a problem that the feeling of stickiness during hair styling and after hair styling stands out. In addition, there is a problem that after hair styling, the oily and unnatural texture becomes glaring.

  In the past, attempts have been made to blend various powders in order to reduce the stickiness caused by oil. Specifically, an oil preparation having a specific melting point, a hairdressing cosmetic containing spherical organic powder (see Patent Document 1), a liquid oil having a specific viscosity, a higher alcohol or a higher fatty acid, and a water-insoluble powder for cosmetics. An emulsified hair cosmetic containing a body, a surfactant, and water (see Patent Document 2), solid waxes and / or solid waxes, a specific sterol, a nonionic surfactant, and a solid powder A hair styling composition containing a body (see Patent Document 3) has been proposed.

  However, these trials can reduce the stickiness due to the oil to some extent, but there is a problem that the texture is inferior to the natural texture and becomes a greasy oily unnatural texture. Moreover, there exists a problem that it is inferior also to re-hair-setting.

  Also, attempts have been made to reduce the greasy oily unnatural texture by blending various powders, and to impart a natural texture and a matte texture. Specifically, it contains a hair styling (see Patent Document 4) containing fine particle nylon powder having a specific average particle size, an oil-swelling clay mineral, a liquid oil at 25 ° C., and a water-insoluble powder. Hair styling (see Patent Document 5) and the like have been proposed.

  However, these trials can give a natural texture and matte texture to some extent, but it is difficult to reduce the sticky feeling due to oil, resulting in inferior re-hairing properties.

  Thus, although the conventional hair wax has the effect which was excellent in the re-hairing property, there exists a problem that it is inferior to a sticky feeling and a natural texture. Therefore, it is a new dosage form that does not exist in the past and replaces an emulsified composition containing oil such as solid oil or liquid oil, represented by hair wax, etc. There has been a demand for the development of a hair styling agent that can impart a texture and also enables re-styling.
