Materials which are used for scouring are known as abrasives. Please see the related link.
Scouring powder is a cleaning agent that contains abrasive particles. It is typically used to scrub and remove tough stains, dirt, and grime from surfaces like sinks, countertops, and tubs. Scouring powders are effective at providing a deep clean but may scratch delicate surfaces.

Loose powder is really nice stuff to wear. It doesn't have the binders and fillers pressed powder does, so it's better for your skin. To convert loose powder into "compact powder," you can buy a compact made to hold loose powder. Bare Minerals sells one that's nice, and it will hold any loose powder, not just Bare Minerals' powder (which is called Mineral Veil).
