A common purple pigment is now too dangerous for most uses in the US
What happened
US environmental regulators are proposing to ban most uses of a common purple pigment, C.I. Pigment Violet 29 (PV29). This means companies can no longer use PV29 in many products, and workers will be protected from exposure.
Why it matters
For decades, companies could use chemicals like PV29 without fully proving their safety. This proposed rule means that once a chemical is found to pose an "unreasonable risk," the US environmental regulators must act to eliminate that risk. It shifts the burden from proving harm after the fact to preventing it upfront, forcing manufacturers to find safer alternatives or implement strict controls.
The signal
Watch for the final rule and its effective date, then observe how quickly manufacturers reformulate products or implement new safety measures for PV29.
