Kieselguhr is more widely known as Diatomaceous earth. It is a naturally occuring, soft, chalk-like sedimentary rock that can easily be crumbled into a white powder. It is used as a filtration aid, a mild abrasive, a mechanical insecticide, an absorbent for liquids, cat litter, and a component of dynamite. Since it is also heat-resistant, it can also be used as a thermal insulator.
I'm not sure about the formula, but it is a form of silica and consists of fossilized remains of diatoms, a type of hard-shelled algae.
Follow the link below to find out more about its uses.

Light-coloured, porous, and friable sedimentary rock composed of the frustrules (silicate cell walls) of diatoms. It is used in industrial filtration applications; as a filler or extender in paper, paint, brick, tile, ceramics, linoleum, plastic, soap, detergent, and other products; in insulation for boilers, blast furnaces, and other high-temperature devices; as a sound insulator; and as a carrier for herbicides and fungicides. The oldest and best-known commercial use is as a very mild abrasive in metal polishes and toothpaste. Large deposits occur in California, Nevada, Washington, and Oregon; other sources are Denmark, France, Russia, and Algeria..
