Therefore, strenuous efforts have been made to reduce the content of the ortho isomers in commercial TCP if there is a risk of human exposure. However, researchers at the University of Washington found that non-ortho TCP isomers present in synthetic jet engine oils do inhibit certain enzymes.
Due to concerns about potential human exposure, significant efforts have been made to reduce the amount of ortho isomers in commercially available TCP. However, a study by researchers at the University of Washington found that certain non-ortho TCP isomers present in synthetic jet engine oils can hinder enzyme activity.
