  • Stripping floor finishes using composition that thickens following dilution with water
    Patent number: 7588645
    Abstract: Floor finishes can be stripped using a substantially nonchlorinated concentrate comprising a floor finish dissolver and an at least partially water-unactivated water thickener. The concentrate is diluted with water at an intended use location to activate the water thickener and noticeably increase within sixty minutes or less the viscosity of the resulting mixture, then applied to a hardened floor finish atop a floor and allowed to soften or dissolve the floor finish so that the finish may be removed from the floor.

  • Water-based pest bait compositions having water-sensitive insecticides and methods of making and use thereof
    Publication number: 20040057977
    Abstract: Compositions, methods-of-preparing, and methods-of-use of a water-based rapid acting insecticidal bait containing a stabilized water-sensitive insecticide as an active ingredient are described. Also described is a storage stable composition containing the water-sensitive insecticide and an insecticide stabilizer, such as boric acid or a nanoparticle. The composition can be easily applied into cracks, crevices, voids, or other pest harborage areas to rapidly kill insect pests, particularly cockroaches.
