What it is
A naturally occurring silicate or magnesium mineral used primarily to prevent powders from clumping together.
How it is used in food
Used as an anti-caking and release agent to stop sticky candies from clumping.
Commonly found in- Chewing gum
- Spices
- Grated cheese
- Wine clarification
Health and safety
The talc itself is inert and not absorbed. The real issue is geological: talc and asbestos form in the same rock, so contamination is the hazard, not the mineral. Food-grade talc must be certified asbestos-free, and the serious findings attached to talc concern inhaled powder, not the small amounts eaten.
Permitted with a specification requiring freedom from asbestos. The distinction between inhalation and ingestion is central to reading any headline about talc.

Identification on labels
- E-number
- E553b
How it is made
Mined naturally from the earth or produced industrially from mineral sources.
- Mining — Mined from natural deposits and finely milled into a food-grade powder.
Worth knowing
It is the softest known mineral on the Mohs hardness scale.
Conclusion
Food-grade talc is a limited concern that is safe to eat in confectionery. Because the mineral itself is inert and unabsorbed, health risks apply to inhaled powders rather than swallowed food. Food-grade talc is strictly required by EFSA to be certified asbestos-free, ensuring sticky candies remain safe.
