Industrial solvents are chemicals that dissolve other substances without chemically changing them. They are widely used to remove solids, grease, and other materials. Solvents can be organic, containing carbon, or non-organic. Common industrial solvents include alcohols, chlorinated hydrocarbons, and hydrocarbons. They are used in applications like pharmaceuticals, cosmetics, agrochemicals, paints, cleaners, and inks. Proper ventilation and protective equipment are important when working with solvents due to their toxicity.
