I’ve had limited development problems myself but here is the quote from both the EPA and Fujifilm: “On March 8, 2021, the Environmental Protection Agency (EPA) finalized a rule regarding the chemical phenol, isopropylated phosphate (3:1) (PIP (3:1)) (CASRN 68937-41-7) under the Toxic Substances Control Act (TSCA), which prohibited the processing and distribution in commerce, including sales, of the chemical and products containing the chemical. EPA also issued an enforcement policy on the same day stating that it will not enforce the ban on processing and distribution until September 5, 2021.”
