This is a crude oil derived from the distillation of petroleum to produce gasoline. Colorless and odorless, mineral oil
is used in baby lotions, cold creams, and ointments. On a more-benign scale, mineral oil has been linked to a number of skin problems, including clogged pores and acne. Untreated and mildly treated mineral oils, however, are also listed as known carcinogens in the National Toxicology Program's
2011 Report on Carcinogens
. Inhalation, skin contact, and ingestion should be avoided.
