Since you are already using mineral spirits, here's a couple of items from a mineral spirits MSDS:
Hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Slightly hazardous in case of skin contact (permeator). The substance is toxic to lungs, the nervous system. Repeated or prolonged exposure to the substance can produce target organs damage.
