EPA issued Data Call-Ins to companies that manufacture or import any of the following nine chemicals currently used as inert ingredients in pesticide products: Acetone, isophorone, di-sec-octyl phthalate, toluene, methyl ethyl ketone, butyl benzyl phthalate, dibutyl phthalate, diethyl phthalate, and dimethyl phthalate. The Data Call-Ins required recipients to submit specific screening data on hormonal effects under EPA’s Endocrine Disruptor Screening Program.

Companies have agreed to submit the screening data rights for two of the inert ingredients: acetone and isophorone. No companies are submitting data for the remaining seven inert ingredients. Consequently, EPA plans to issue new test orders for acetone and isophorone. EPA will not require testing for the other seven chemicals, and will no longer approve their use as inert ingredients in pesticide products. Any comments on these actions must be received by EPA on or before May 14, 2012.
