Abstract
Abstract A composition employed to sorb oleophilic material from a surface, especially a composition to preferentially sorb an oleophilic substance from a hydrophilic substance, e.g., comprising a foraminous substrate impregnated with a drying oil; a method of removing an oleophilic material from a surface which comprises contacting the same with a composition comprising a foraminous substrate, said substrate impregnated with a drying oil; a method of removing an oleophilic liquid from a hydrophilic liquid which comprises contacting a mixture thereof with a foraminous substrate impregnated with a drying oil.
