Patent number: 5705472Abstract: An aqueous cleaning composition having a pH of about 6 to about 8 and comprising a solution of the following ingredients: water, an organic solvent and an imidazoline-based cationic surfactant, each present in an amount effective to dissolve adherent soils from a substrate; and a nonionic surfactant in an amount sufficient to maintain said cationic surfactant in solution; and also a weak organic acid in an amount sufficient to impart to the composition said pH; wherein said composition is substantially free of any material which has an ozone-depletion factor of greater than about 0.15 and wherein said composition is substantially free of any material which would tend to form a solid with any of the ingredients comprising the composition, and its use to clean metallic and non-metallic surfaces.Type: GrantFiled: July 18, 1995Date of Patent: January 6, 1998Assignee: Petroferm Inc.Inventors: Michael E. Hayes, Elizabeth A. Bivins, Jacquelyn B. Coleman

Patent number: 5705470Abstract: A substantially homogeneous sprayable cleaning gel composition which is substantially free of suspended encapsulated particles exhibits extended dwell time when sprayed on to a surface as compared to a low viscosity spray cleaner. The extended dwell time and anti-static properties of the sprayable cleaning gel composition give rise to several benefits and advantages. The sprayable cleaning gel composition housed in a spray applicator is usable to clean surfaces at any angle. A preferred method of cleaning surfaces is also described.Type: GrantFiled: December 15, 1995Date of Patent: January 6, 1998Assignees: Edward F. Topa, Theodore P. Faris, Peter D. KeefeInventor: Theodore P. Faris
