There are people that notice negative physical reactions from handling tool handles with dried boiled linseed oil on them. So it may be possible that the chemicals are being absorbed through the skin even when dry. There are other examples of chemicals that do this.
Why support companies making toxic chemicals that don't care about your health when there is a better way to do it which would also be food safe?
As for food grade mineral oil on food surfaces, I don't worry about a beeswax mineral oil treatment either on butcher block or wood bowls. It is in small quantities, and limited contact. If I found scientific info proving it was bad even in small amounts that would change. At least be aware of where it comes from.
