  • Patent number: 11187129
    Abstract: An exhaust gas purification including: a base of wall flow structure having inlet side cells wherein an end on the exhaust gas inflow side is open and outlet side cells wherein an end on the exhaust gas outflow side is open, and a porous partition wall that partitions the side cells; and first and second catalyst layers disposed in the interior of the porous partition wall so as to be in contact with the side cells, wherein either of the catalyst layers contains an oxidation catalyst but does not contain a reduction catalyst, and the other contains the reduction catalyst but does not contain the oxidation catalyst; and a ratio of the lengths of the catalyst layers differs between a surface of the porous partition wall on the side in contact with the inlet side cells and a surface on the side in contact with the outlet side cells.

  • Patent number: 10143636
    Abstract: A porous silica particle optimized as the scrubbing agent is used for a cleansing cosmetic. The porous silica particle has an average circularity of 0.1 to 0.5, a pore volume of 1.0 to 2.0 ml/g, a mode diameter of 50 to 600 ?m, and a ratio of the maximum particle diameter to the mode diameter of 3.0 or less. The porous silica particle moreover has a median size of 0.5 to 25 ?m and the maximum particle diameter of 1 to 100 ?m, after rubbing with a load of 1.0 to 1.4 KPa for 30 seconds. With the cleansing cosmetic containing this particle, the skin is rubbed by the frictional force generated by the friction with the skin at the rubbing. Therefore, the mild peeling effect for the stratum corneum is obtained and the damage of the skin and the micro damage on the stratum corneum can be prevented.

  • Patent number: 9889072
    Abstract: A porous silica particle with the small specific surface area and large pore volume, which is contained as the scrubbing agent in the cleansing cosmetics is provided. The porous silica particle has high collapsibility, and therefore the damage of the skin can be prevented. A porous silica particle according to the present invention has: an average circularity of 0.1 to 0.5; a pore volume of 0.1?Pv<1.0 ml/g; a specific surface area of 5 to 60 m2/cm3; a median size of 100 to 1000 ?m; a ratio of a maximum particle diameter to the median size, of 3.0 or less; and a median size of 5 to 40 ?m and a maximum particle diameter of 15 to 200 ?m, after rubbing for 30 seconds with a load of 1.0 to 1.4 KPa.

  • Patent number: 9808407
    Abstract: An object of the present invention is to provide a porous silica particle with the small specific surface area and the large pore volume, a method for producing the same, and a cosmetic containing the porous silica particle with such characteristics as the texture improver. The porous silica particle according to the present invention has a structure sparsely packed with silica microparticles. The mean particle diameter is 0.5 to 25 ?m, the specific surface area measured by the BET method is 5 to 60 m2/cm3, and the pore volume is 0.35 to 2.0 ml/g. In the pore size distribution of the porous silica particles (X axis: pore diameter, Y axis: value obtained by differentiating the pore volume by the pore diameter), the most frequent pore diameter (Dm) satisfies 100<Dm<4000 [nm].
