How to reduce your exposure when touching NMP?

N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. Even though impure samples might seem yellow, it is a colorless liquid. With water and the majority of typical organic solvents, it is miscible. In order to utilize it as a solvent in the petrochemical, polymer, and battery sectors, it must be nonvolatile and have the capacity to dissolve a wide range of compounds.

When NMP is tested on pregnant animals, the growing fetus is harmed. Both male and female test animals' reproductive systems are poisoned by it. NMP's effects on reproduction have not been investigated in humans.

We should consider NMP to be a possible threat to human reproduction based on the animal studies. The eyes, skin, nose, and throat get irritated with excessive NMP exposure.It can also have an impact on the brain or central nervous system, creating symptoms of intoxication comparable to those brought on by consuming alcohol. NMP absorbs quickly via the skin. It is frequently used to substitute for hazardous chemicals like methylene chloride and other chlorinated solvents.

How NMP enters your body?

NMP enters your body when it comes into contact with your skin and when you breathe in its vapors or spray droplets. The quantity of NMP that enters your body determines the likelihood of adverse health consequences. This mostly depends on how much (or what concentration) of NMP is inhaled by you, how much of it affects your skin, and how long you are exposed to it for.

How NMP can affect your health?

NMP's toxicity to humans has not been thoroughly investigated. Not human usage of NMP, but rather animal experimentation, accounts for the majority of the knowledge. Chemical impacts on human health are frequently assessed using animal testing.

Reproductive system

In a number of studies, pregnant animals exposed to NMP experienced delayed growth in their progeny. Additionally, NMP prolonged the gestation period for female rats and decreased male rats' fertility. There hasn't been any research on how NMP affects human fertility.

Nervous system

As with other organic solvents, NMP can have an impact on your brain. Breathing excessively for a brief length of time results in symptoms similar to being intoxicated, such as headache, nausea, dizziness, clumsiness, and sleepiness.The symptoms of shortterm exposure usually clear up within hours after exposure stops.

Over months or years, repeated, regular overexposure to NMP and other solvents can have long-lasting, perhaps irreversible effects on the neurological system. Fatigue, lack of sleep, poor coordination, problems focusing, loss of short-term memory, and personality changes including sadness, anxiety, and irritability are some of the symptoms of these long-term impacts.

Eyes,nose,throat and skin

NMP irritates the throat, nose, and eyes. Through your skin, it is immediately absorbed into your body. NMP can result in dermatitis (dry, rough, red, or cracked skin) by dissolving the natural protective oils in your skin.

How to reduce your exposure?

Employing ventilation and other controls, as well as work practices to reduce your exposure to dangerous chemicals like NMP, employers are required by law to offer a safe and healthy workplace.Here are some ways employers and employees can work together to reduce exposures.

Using less

Use as little as possible of solvent-containing products. Keep containers closed between uses.


Verify that there is enough ventilation. The best ventilation is "local exhaust ventilation". Fume hoods ought to be utilized in labs. The next best method for introducing fresh air into the workspace is through general ventilation utilizing a fan-powered system or a heating, ventilation, and air conditioning system. Typically, relying just on open doors and windows won't supply enough fresh air.

Skin protection

When utilizing items that contain NMP, put on protective utility gloves. Less robust gloves consisting of natural rubber, nitrile, or polyethylene will not withstand NMP. Alternate gloves often. If NMP can come into contact with your skin in places other than your hands, use chemical protective equipment such as aprons, sleeves, boots, and head and face protection. After every use, properly clean the equipment.
