Talcum is versatile. It is used as a finely ground filler in the paper and cellulose industry, the paint and varnish industry as well as the rubber, plastics and ceramics industry. Talcum is also used as a powder base, as a lubricant (to improve the flow properties of powders). Talcum has a good absorption capacity for oils. However, it can only absorb very small amounts of water.

Talc is approved in the EU as a food additive with the number E 553b.
