Abstract:

To provide a skin cosmetic imparting the skin with clear feeling, trimming skin texture and making the poil foramens in the skin inconspicuous by formulating disintegrable porous spherical silica.

This skin cosmetic is obtained by formulating a cosmetic base with the porous spherical silica in the form of powder having a mean size (on a volume basis) of 3.0-20 μm, maximum size of ≤50 μm and pore volume of 1.5-3.0 cm3/g. The silica has also the following property: when the dynamic viscoelasticity in its pasty form is measured and then the correlation of log (storage modulus) vs. log (shearing stress) is determined, the minimum value of dlog (storage modulus)/dlog (shearing stress) is ≥-10.
