Zinc Pyrithione (Formerly Known as Omadine Salts) Preliminary Risk Assessment; Notice of Availability

Résumé

This notice announces the availability of EPA's preliminary risk assessment, and related documents for the antimicrobial pesticide zinc pyrithione (also referred to as zinc omadine), and opens a public comment period on these documents. The Agency has changed the reregistration case name for this chemical from "omadine salts" to "zinc pyrithione" to accurately reflect the sole active ingredient in this case. Previously, the omadine salts case contained two active ingredients (zinc omadine and tert-butylamine 2-pyridinethiol-1-oxide). The rationale for changing the case name is that: Omadine is a registered trade name and the Agency prefers not to use trade names as titles of documents; the plural "salts" in the case name indicates multiple actives but there is only one chemical being considered (i.e., zinc pyrithione); harmonize the case name with the sole active ingredient; and the second chemical previously listed in this case (i.e., tert-butylamine 2-pyridinethiol-1-oxide; PC code 088005) has no active registered products and is no longer a registered active ingredient. The public also is encouraged to suggest risk management ideas or proposals to address the risks identified. E
