DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composition for removing domestic shine which has an effect of removing shine generated from wool or wool / synthetic fiber mixed clothing.

[0002]

2. Description of the Related Art When wearing hair such as suits, uniforms, student clothes, sailor clothes, or hair / synthetic fiber mixed garment for a long period of time, a local area called "tekari" is applied to elbows, knees, hips, etc. There is often seen a phenomenon in which a characteristic gloss is generated and the appearance of clothing is significantly impaired. In addition, repeated ironing of the garment may cause scale on the surface.

[0003] The cause of shining is that, after prolonged wearing or ironing, the fine irregularities of the woven structure on the cloth surface become flat due to friction and compression, and the cuticle structure peculiar to wool fibers is worn out. Detachment and smoothing.
As a result, the intensity of specular reflection light (specular reflection light) of light on the clothing surface increases, and the clothing surface appears to shine. This phenomenon is more noticeable in dark colored clothing with low light reflectance.

As a means for preventing the occurrence of flashes, it is effective to some extent to apply a cloth and iron with steam when ironing, but it is difficult to sufficiently prevent the occurrence of flashes.

Further, Japanese Patent Application Laid-Open Nos. 64-61576 and 2-3079
No. 81, Japanese Patent Application Laid-Open No. Hei 3-82874 discloses a composition in which the hair or the bristles produced on the wool / synthetic fiber mixed clothing contains an amino-modified organopolysiloxane and / or a quaternary ammonium salt-modified organopolysiloxane. It can be prevented by treating with. Although this method has an effect of suppressing shining, a small amount of the treatment does not have a sufficient effect, and an excessively large amount of the treatment results in a remarkable dark color, and a domestic treatment may cause partial spots and unevenness.

DISCLOSURE OF THE INVENTION The present inventors can easily remove the shine generated from wool or wool / synthetic fiber mixed clothing at home, and wash the shine removal composition at home washing or dry cleaning. As a result of diligent studies to find a composition for removing the shine of clothing that can be removed by using, a dispersion containing specific solid fine particles and a surfactant was used to achieve this object. This led to the completion of the present invention.

That is, the present invention is characterized by comprising (a) solid fine particles having an average particle diameter of 1 nm to 2 μm and a refractive index in the range of 1.3 to 2.0, and (b) a dispersion containing a surfactant.
