Patent number: 5543085Abstract: A polish-lacquer remover is provided that includes a volatile organic solvent, a thickening agent and an electrolyte. The most preferable combination is that of an acrylate/vinyl acetate cross polymer and 2-ethylhexyl alkyl ammonium methosulfate. Compositions of this invention are thickened but do not suffer from tacky or sticky residues upon solvent evaporation and have good lacquer removing efficacy.Type: GrantFiled: March 24, 1995Date of Patent: August 6, 1996Assignee: Chesebrough-Pond's USA Co., Division of Conopco, Inc.Inventor: Philip E. Miner

Patent number: 5538664Abstract: Hard surface detergent compositions comprise nonionic detergent surfactant; tripropylene glycol or short chain alkyl ether of tripropylene glycol as a hydrophobic cleaning solvent; and optional, but preferred suds control system comprising fatty acid and anionic sulfonated and/or sulfated detergent surfactant. The compositions are preferably in the form of aqueous liquids and preferably have monoethanolamine and/or beta-aminoalkanol present. The compositions clean vinyl no-wax flooring without rinsing and without substantial filming/streaking.Type: GrantFiled: December 29, 1993Date of Patent: July 23, 1996Assignee: The Procter & Gamble CompanyInventor: Daniel W. Michael

Patent number: 5534184Abstract: Disclosed are concentrated alkaline liquid detergent compositions suitable for dilution with hard or de-ionized water. The compositions can be stored before and after dilution for prolonged periods at temperatures ranging from about 40.degree. F. (4.degree. C.) to about 100.degree. F. (38.degree. C.) without precipitates forming. The compositions contain a maleic acid-olefin copolymer, a detergent surfactant, a solvent/buffer system comprising beta-aminoalkanol and/or monoethanolamine, and less than about 85% water. The copolymer acts as a crystallization inhibitor and is uniquely soluble in the concentrated liquid detergent compositions.Type: GrantFiled: October 19, 1994Date of Patent: July 9, 1996Assignee: The Procter & Gamble CompanyInventor: David C. Underwood
