Need to Know Information

The U.S. Environmental Protection Agency (EPA) has issued a Data Call-In (DCI) for the active ingredient para-tertiary amylphenol (PTAP), a phenolic active ingredient found in some registered disinfectants. PTAP active ingredient manufacturers have chosen not to support the DCI, and as a result, PTAP disinfectant products will soon no longer be compliant and available on the market in the U.S.
