Abstract
Although improvements in formulations of cutting and grinding fluids have been made, occupational dermatitis can still be a problem. Oil acne and folliculitis are the most common cutaneous problems of those who work with insoluble oils. Bacteria in lubricating coolants may contribute to breakdown of the coolant but are unrelated to outbreaks of folliculitis. The chief problem which results from exposure to soluble oils and synthetic coolants is eczematous contact dermatitis, a disease of multiple causation. These two important skin diseases as well as several minor ones associated with exposure to lubricating coolants can be prevented by measures designed to minimize contact and to improve personal hygiene.
