This notice applies only to existing registrants of certain, currently registered pesticide disinfectant products containing the specified active agreements listed in the PR 98-10 amended notice.

This PR notice only applies to products found on EPA’s List N: Disinfectants for Use Against SARS-CoV-2.

This amendment allows for the temporary procurement of eight specified active ingredients from any source, as long as the unregistered source is chemically similarly to the current source, without prior approval by the US EPA of an amendment to the registrant’s pesticide registration.

The eight specified active ingredients are as follows:

Chemical Name CAS Number
Citric acid 77-92-9
Ethyl alcohol 64-17-5
Glycolic acid 79-14-1
Hydrogen peroxide 7722-84-1
Hypochloric acid 7647-01-0
Hypochlorous acid 7790-92-3
L- Lactic acid 79-33-4
Sodium hypochlorite 7681-52-9

The registrant must notify the EPA using the CDX portal of its intent to use one or more alternate, unregistered sources of active ingredient by completing the application. Once submitted, the registrant must email with their CDX tracking number. Once the EPA receives the notification, the registrant may distribute or sell the product modified according to this temporary amendment.

The US EPA will continue to assess the situation and will provide a notification seven days in advance of termination of this temporary amendment by posting such notice at After this termination, the registrants must revert back to sources identified in the registered products approved confidential statement of formula (CSF); otherwise in order for the registrants to continue using the alternate source, the registrant would need, as per EPA’s existing prescribed requirements, to amend their confidential statement of formulation (CSF).

This action became effective on March 30 without the usual public comment period due to the critical need for availability of effective disinfectant products and the wide availability of the specified eight commodity chemicals.

If this notice affects you, please carefully read PR 98-10 for full details of all requirements.
