What it is + why it's regulated

Methyloxirane, also known as propylene oxide, is a chemical used mainly to make other substances like plastics, antifreeze, and some industrial cleaners. It is a colorless, flammable liquid with a faint sweet smell. The European Chemicals Agency (ECHA) lists it on the REACH Candidate List of Substances of Very High Concern (SVHC) because it is classified as a carcinogen (can cause cancer) and a mutagen (can cause genetic damage). This means it may pose serious risks to human health and the environment. It is regulated to limit exposure in workplaces and consumer products, and companies must inform customers if it is present above certain levels.
