Methanol has a half-life of around 18 days after volatilization into the air, when it reacts with airborne hydroxyl radicals. Rainfall is one way to extract methanol from the air. Methanol is anticipated to break down through biodegradation if it is discharged into water....

If your skin comes into touch with NMP in places other than your hands, wear protective clothes such as aprons, sleeves, boots, and head and face protection. After every usage, make sure the equipment is completely clean.

NMP shown minimal acute toxicity when exposed orally, topically, and through inhalation. NMP irritated the skin almost never, but it did cause mild ocular irritation.

Member of the class of pyrrolidine-2-ones, N-methylpyrrolidin-2-one is pyrrolidin-2-one in which a methyl group has been added in place of the hydrogen bonded to the nitrogen. It serves as a solvent that is polar and aprotic.

A common solvent, n-Methyl-2-pyrrolidone (NMP), has a faint amine-like smell and can evaporate or form an aerosol at room temperature. NMP has been shown to cause headaches and mild, momentary eye discomfort in humans.

A flexible water-miscible polar aprotic solvent is N-methyl-2-pyrrolidone (NMP). It is applied to both humans and animals as a medication solubilizer and penetration enhancer, however its bioactivity characteristics are still unknown.

The perfect substitute for NMP is TOU (2,5,7,10-Tetraoxaundecane). Surface tension is significantly lower than that of NMP, yet physical properties like boiling point, flash point, and viscosity are extremely similar. It is compatible with a broad variety of rubber and polymers and has excellent solvent power.

Even at 25 degrees Celsius, methanol spontaneously evaporates due to its extremely low vapor pressure of approximately 143 mmHg, while having a boiling point of 64.7 degrees Celsius.

On May 9, 2020, the restriction became operative. Because of its developmental toxicity and potential toxicity for reproduction, the European Chemicals Agency has classified NMP as a [Substance of Very High Concern."...
