摘要： Coating remover compositions comprising an alkylene carbonate, hydrogen peroxide, water, a first alcohol, a second alcohol, and, optionally, pine oil that exhibit low toxicity. Further, a method of removing a coating from a surface. The method involves contacting a composition comprising an alkylene carbonate, hydrogen peroxide, water, a first alcohol, a second alcohol, and optionally, pine oil to a coated surface, and allowing the composition to contact the coated surface for a period of time, and under conditions effective to cause blistering of the coating. The compositions and method of the present invention are particularly suited for use with varnishes.
