Expert Verdict

Contains fluoride - oral ingestion should be avoided; derived from talc (potential asbestos-related concerns in source material must be addressed); skin irritation possible in sensitive individuals. Produced by heating talc with potassium silicofluoride at high temperature; the reaction transforms the mineral structure to create a fine bulking powder; integrates properties of its constituent elements (Mg, K, Si, F) into a single functional compound
