Patent number: 5545749Abstract: A quaternary ammonium compound solution comprising from about 50% to about 80% of a quaternary ammonium compound and from about 20% to about 50% of a solvent. The solvent being from about 25% to about 100% of alkylene glycol with the remainder being water. The method of making quaternary ammonium compounds comprises reacting methyl chloride and/or benzyl chloride and dialkylmethylamine and/or alkyldimethylamine in an alkylene glycol to completion and diluting the same with sufficient water to a solution in which the alkylene glycol is from about 25% to about 100% of the solvent component of the total solution and the quaternary ammonium compound is from about 50% weight to about 80% weight of the quaternary ammonium compound solution.Type: GrantFiled: October 5, 1994Date of Patent: August 13, 1996Assignee: Huntington Laboratories, Inc.Inventors: Kim R. Smith, Frederick M. Boyd, Samih S. Abouhalkah

Patent number: 5389685Abstract: The color-stability of disinfectant formulations comprising bacteriocidal quaternary amine compounds, a non-ionic surfactant, and water is enhanced significantly by adding color-stabilizing amounts of an alkali bicarbonate. An alkali bicarbonate can be used in lieu of the art-accepted EDTA/NaOH builder in quaternary amine-based disinfectant formulations to enhance color stability without sacrificing the bacteriocidal efficacy of the formulations.Type: GrantFiled: June 10, 1993Date of Patent: February 14, 1995Assignee: Huntington Laboratories, Inc.Inventors: Kim Smith, Fred Boyd

Patent number: 5385604Abstract: Floor polish compositions having good resistance to germicide solutions are described. They comprise styrenated acrylic resins in combination with a rosin ester resin, a wax and other floor finish functional ingredients. Optimum floor polish performance characteristics are obtained when the weight ratio of the rosin ester and wax is greater than one and when the weight ratio of the styrenated acrylic resin to the total weight of the rosin ester resin and wax components is between about 3:1 and about 7:1.Type: GrantFiled: December 20, 1993Date of Patent: January 31, 1995Assignee: Huntington Laboratories, Inc.Inventor: Neil T. Ainslie

Patent number: 4464398Abstract: An improved bactericide, fungicide and viricide comprising about three parts weight didecyl dimethyl ammonium chloride having the structural formula of: ##STR1## and about two parts weight of n-akyl (C14 50%, C12 40%, C16 10%) dimethyl ammonium chloride having the structural formula of: ##STR2## where R equals (C14 50%, C12 40%, C16 10%) In specific embodiments, the composition of the invention may include a non-ionic detergent, a detergent builder, diluents and/or other non-active ingredients. The method of the invention comprises bringing an inaminate article into contact with a solution of the improved germicidal composition of the invention in an appropriate use-dilution concentration. Totally surprising kills of bacteria, fungus and viruses when the improved germicidal composition is diluted with water, hard water, water in the presence of about 5% weight organic soil and hard water in the presence of 5% weight organic soil simultaneously.Type: GrantFiled: August 11, 1981Date of Patent: August 7, 1984Assignee: Huntington Laboratories, Inc.Inventors: Richard D. Sheets, Donald R. Huffman
