Did FDA file Doehler's calcium sulfate color additive petition in 2026?

Yes. FDA published a Federal Register filing notice on September 25, 2026, logging Doehler GmbH’s color additive petition for calcium sulfate under Docket No. FDA-2026-C-10597 and 21 CFR 73. The notice reflects an early procedural step, not an approval or commercialization clearance.
