Mineral oil can be found in most pharmacies marketed as a laxative. It's a common oil to use for cutting boards and other applications in proximity to food.
Right, another instance of where the mineral product is to be much preferred over the so-called natural one is with turpentine.
Mineral turpentine is to be much preferred over the natural one because the latter contains organic wood terpenes many if which are toxic and proven carcinogens - after all it stands to reason that they're dangerous, as trees have evolved to produce them to fend off or poison insects that attack them.
I find it somewhat distressing to see so many carpenters and woodworkers using terpenes-laced turpentine because they believe 'natural' is better.
