Registration: Registered as a pesticide (first registered October 20, 1948). 17 formulated products contain it.
Main registered crops: citrus, apple, peach, deciduous fruit trees, mulberry, persimmon and others (49 crop names in the registered uses)

Evaluations abroad

WHO acute toxicity class: Not listed in the WHO 2019 tables
Based on the toxicity of the undiluted active ingredient given once, mainly to rats by mouth (LD50 = the dose that kills half; the smaller, the stronger the acute toxicity). It is not an assessment of the safety of residues in food.
EU: Partly approved in the EU
In the EU, it is reviewed by CAS number. Of 11 paraffin oils, 4 are approved and 7 are not approved.
EU ADI: Paraffin oil/(CAS 64741-88-4)=Not Applicable / Paraffin oil/(CAS 64742-54-7)=Not Applicable; ARfD: Paraffin oil/(CAS 64741-88-4)=Not Applicable / Paraffin oil/(CAS 64742-54-7)=Not Applicable
