Other companies add MEK to adhesives, printing inks, paint removers, and special lubricating oils. Companies also use MEK to make other chemicals, including those used as drugs and cosmetics. Small amounts of MEK are used to sterilize surgical instruments, hypodermic needles, syringes, and dental instruments. It is also used to extract vegetable oil. Exposure to MEK can occur in the workplace or in the environment following releases to air, water, land, or groundwater.
Exposure can also occur when people use certain paints, paint removers, or adhesives.
Methyl ethyl ketone enters the body when breathed in with contaminated air or when consumed with contaminated food or water. It can also be absorbed through skin contact. It is not likely to remain in the body due to its breakdown and removal in expired air and in urine. Methyl ethyl ketone evaporates when exposed to air. It dissolves when mixed with water.
