Abstract
Environmentally safe, e.g. biodegradable, paint stripper compositions comprising 10-99 parts dimethyl esters of C4-C6 aliphatic dibasic acids, 0.1-40 parts polyvinyl butyral and 1-90 parts water. The compositions can be mixed, e.g. in high shear to provide stable emulsions which strip paint, e.g. varnish from wood. Certain embodiments of the invention also comprise water soluble organic solvents, water-miscible organic solvents, surfactants, emulsifiers, thickeners and/or pigments.
