    Inventors: Timothy J. Taylor, Alan F. Richter
  • Patent number: 5728667
    Abstract: Germicidal light-duty dishwashing detergent composition in either a gel, liquid, or semi-liquid form, which consists essentially of:0.5-2.75 parts quaternary ammonium germicidal compound0.5-40 parts by weight of an anionic alkyl ether carboxylate surfactant of formula:R--O--(C.sub.2 H.sub.4 O).sub.x --CH.sub.2 --COO.sup.- M.sup.+where x is 4 to 11, R is a C.sub.9-18 alkyl, M is counterion;10-40 parts by weight of an nonionic surfactant;0.01-30 parts by weight of an of a suds boosting agent; water;0-40 parts by weight of one or more additives, wherein the ratio of the quarternary ammonium germicidal agent to the anionic alkyl ether carboxylate surfactant is 1:1-4, and, the compositions exhibit a pH in the range of 5-10.The compositions are excellent dishwashing detergents particularly suited for manual dishwashing operations, and further provide good cleaning with an effective sanitizing effect.

  • Patent number: 5728672
    Abstract: A pine oil cleaning concentrate composition comprising as essential constituents: pine oil, a nonionic surfactant with a cloud point of 20.degree. C. or less, a solubilizing agent and, water, feature reduced levels of volatile organic contents, including reduced amounts of pine oil, yet provides good blooming characteristics upon mixing of the concentrate composition with a further amount of water to produce a cleaning composition therefrom. The pine oil cleaning compositions may further include conventional additives, including germicidal agents, viscosity modification agents, fragrances (natural or synthetically produced), foaming agents, further surfactants, and coloring agents.

  • Patent number: 5629280
    Abstract: A pine oil type cleaning concentrate composition comprising as essential constituents: pine oil, one or more pine oil solubilizing agents, cationic surfactant, anionic surfactant, a surfactant compatibilizing agent, and water. Compositions according to the invention feature reduced levels of volatile organic contents, including reduced amounts of pine oil, yet provide good blooming characteristics upon mixing of the concentrate composition with a further amount of water to produce a cleaning composition therefrom. The pine oil cleaning compositions may further include conventional additives, including germicidal agents, viscosity modification agents, fragrances (natural or synthetically produced), foaming agents, detersive agent, co-surfactants, and coloring agents.
