Abstract

Abstract A cleaner for cleaning from hands and the like difficultly removable objectionable material such as modern catalyzed auto paint, fast drying printers ink and the like characterized by a multi-component composition that includes at twenty-five percent by weight and no more than sixty percent by weight of dibasic ester consisting essentially of an admixture of dimethyl succinate, dimethyl glutarate and dimethyl adipate; at least five percent by weight and no more than twenty-five percent by weight of dipropylene glycol methyl ether; at least five percent by weight and no more than twenty-five percent by weight of oderless mineral spirits; at least four percent and no more than nine percent by weight of triethanolamine; at leat five percent and no more than fifteen percent by weight of octylphenoxypolyethoxyethanol in which there are seven to eight moles ethylene oxide per mole of octyl phenol; at least one percent and no more than three percent by weight of nonyl phenol ethoxylate having about four moles of ethylene oxide per mole of nonyl phenol; and at least eight and no more than eighteen percent by weight of tall oil fatty acid.
