US EPA List of Inerts. This substance is on List 3.

Note: US EPA allows so-called "Inert" ingredients to be commonly mixed with the "active" pesticidal ingredient to create a formulated pesticide product. According to EPA, "The term `inert' is not intended to imply nontoxicity; the ingredient may or may not be chemically active." "Inert" ingredients include solvents, emulsifiers, spreaders, and other substances mixed into pesticide products to increase the effectiveness of the active ingredients, make the product easier to apply, or to allow several active ingredients to mix in one solution. Both US EPA and California Department of Pesticide Regulation require pesticide manufacturers to identify inert ingredients in their products but do not disclose this information to the general public because the pesticide industry considers product formulations trade secrets, protected by law and by the US EPA. The US EPA category of Inerts (as of September 2003):

List 1 - Of Toxicological Concern
List 2 - Potentially Toxic / High Priority for Testing
List 3 - Of Unknown Toxicity
List 4A - Generally Regarded as Safe
List 4B - EPA states it has Sufficient Information to Reasonably Conclude that the Current Use Pattern in Pesticide Products will not Adversely Affect Public Health or the Environment
List 4 (all)
The complete list of Inerts as listed by EPA in 2001 - (several inerts have been removed since this date).
