Talc & Major Regulatory Frameworks — REACH, RoHS, FDA
1 EU REACH (Registration, Evaluation, Authorisation & Restriction of Chemicals)
| Item | Status for Talc |
|---|---|
| Substance ID | EC No. 238‑877‑9 — Hydrated magnesium silicate. |
| Tonnage band | ≥1 t yr⁻¹ importer/manufacturer must have a registration dossier. |
| Current classification | Not classified as hazardous (Annex VI), provided asbestos <0.1 %. |
| Key dossier elements | Section 4.5 inhalation toxicity, nano-form annex; CSR required >10 t yr⁻¹. |
| Updates 2023‑25 | ECHA draft revision adds mandatory nano‑particle size distribution data (Annex VI 2.4). |
| Practical impact | EU customers ask for REACH Registration Number on SDS and for confirmation “no substances of very high concern (SVHC) present”. |
2 EU RoHS (Restriction of Hazardous Substances)
RoHS targets electrical & electronic equipment, not minerals per se. Talc is affected only when used as plastic filler in housings, cables, FR masterbatch.
| Controlled element | Limit (homogeneous material) | Relevance to talc |
|---|---|---|
| Pb, Hg, Cd, Cr⁶⁺, PBB, PBDE, DEHP, BBP, DBP, DIBP | 0.01–0.1 % (w/w) | Ensure trace metals in talc < ten‑ppm range; provide heavy‑metal screen on COA to OEMs. |
Key point: The polymer compounder holds legal responsibility, but talc supplier provides heavy‑metal statement → keeps supply chain RoHS compliant.
3 US FDA (Food, Drug & Cosmetic Act)
a) Food‑contact (Indirect additive)
-
CFR 21 § 175.300 (Resinous & polymeric coatings) and § 177.1655 (Polyolefin articles). Talc may be used as filler in accordance with good manufacturing practice.
-
Heavy metals: Pb < 10 ppm, As < 3 ppm, Hg < 1 ppm (FDA Guidance 2022). Industry supplies COA + heavy‑metal panel.
b) Cosmetic talc
-
No positive list, but product must be safe; FDA conducts CTFA Method J4‑1 asbestos screening. Practical market requirement: <0.01 % asbestos (TEM).
-
2024 draft rule proposes mandatory asbestos test & batch records; final rule expected 2026.
c) OTC & Pharma (excipient)
-
USP‑NF Monograph “Talc”:
-
Acid‑insoluble matter ≤ 16 mg g⁻¹;
-
Microbial limits < 100 CFU g⁻¹;
-
Asbestos absent (TEM).
-
4 Supplier action checklist
-
Maintain REACH registration dossier (update nano annex by Oct 2025).
-
Provide RoHS heavy‑metal statement with every pigment‑containing grade.
-
Issue FDA‑style COA (Pb, As, Hg, Cd) for any food‑contact or cosmetic shipment.
-
Keep TEM asbestos certificate on file for all cosmetic/pharma talc, cross‑reference batch on invoice.
