Abstract
A powder compact material in the form of a stick for cosmetic purposes is made up of powder-like base materials and if necessary additions of binders, lubricants and materials increasing adhesion compacted or bonded together as a body which keeps its form. For stopping the end or outer face of the stick-like body becoming clogged with moisture and sebum on use (so that clean powder compact material would have to be uncovered by cutting, this wasting the material) the compact stick contains as part of the present invention, a particle material, whose particles are harder than the particles of the base materials. The hardness of the particle material may preferably be equal to at least 4.0 on the Mohs' hardness scale. A particle size of 10 to 50 microns and an outer face of the particles which as far as possible is jagged or otherwise rough is responsible for useful effects. Particle materials which may be used are more specially pumice powder, quartz flour, aluminum oxide (corundum) metal carbides, metals and the like, and mixtures thereof. The level of the particle material is more specifically 20 to 40% of the overall weight of the compact material.
