    Abstract: The invention provides porous particles having a mean particle diameter of as small as 75μm or below; composite porous particles obtained by incorporating an active ingredient into the above porous particles; processes for the production of both; and cosmetics containing the same. The invention relates to porous particles which are made mainly of a polyethylene resin having a degree of crystallization of 70% or above and have a mean particle diameter of 75μm or below; composite porous particles obtained by incorporating an active ingredient into the above porous particles; cosmetics containing the porous particles or the composite porous particles; and a process for the production of the porous particles which comprises mixing a polyethylene resin having a degree of crystallization of 70% or above with a low-molecular compound having a melting point lower than the softening (or melting) point of the polyethylene resin at a temperature equal to or higher than the softening (melting) point of the polyethylene resin, spraying the obtained mixture into a gas phase or a solvent at such a temperature that the mixture exhibits a viscosity of 600mPa s or below, and removing the low-molecular compound from the resulting particles.

    Abstract: A process for producing non-crystalline cellulose with excellent productivity, wherein a cellulosic raw material in which the components thereof excluding water have a cellulose content of 20 mass% or higher and the cellulose has a cellulose I crystallinity, shown by the following calculation formula (1), of higher than 33% and which has a water content of 1.8 mass% or lower is treated with a pulverizer to reduce the cellulose I crystallinity thereof to 33% or lower. Cellulose I crystallinity (%) = [(I22.6-I18.5)/I22.6]×100 (1) [I22.6 indicates the X-ray diffraction intensity of the lattice plane (002) (diffraction angle 2? = 22.6º) and I18.5 indicates the X-ray diffraction intensity of the amorphous part (diffraction angle 2? = 18.5º).]
