Definitions

  • My present invention is generally directed to an arthropodicidally-active composition-of-matter and to its method of manufacture.
  • My novel composition-of-matter is generally characterized as a stable foam matrix. Still more particularly, my novel arthropodicidally-active stable foam matrix is water-soluble.
  • arthropod which is generally understood by those skilled in the art of "pest” control as connoting any member of a large group of invertebrate animals with jointed legs and segmented bodies.
  • arthropod in its "generic" sense so as to include arachnids, crustaceans, insects and myriapods.
  • U.S. Pat. No. 3,816,610 to Lusby discloses a so-called "palatable", foamed rodent-control material.
  • a rodent-control material more particularly, is said to comprise a rodent control agent such as a rodenticide which, in turn, is interspersed throughout a so-called “plastic foam cellular” structure.
  • the foam cellular structure is produced by combining isocyanate with a mixture consisting of a polyol, a catalyst, a blowing agent, and a so-called “rodent- control” agent.
  • Lusby discloses that such ingredients, after being thus combined, react chemically and expand in volume up to fifty (50) or more times, via so-called “foaming action”.
  • Lusby further discloses that the result of such a volume expansion is the production of a low-density substance or mass (i.e., a "foam”), which is said to be able to fill up cavities and take their shape, wherein such a mass quickly becomes rigid.
  • a low-density substance or mass i.e., a "foam”
  • U.S. Pat. No. 3,524,911 to Leavitt discloses an insecticidal composition. More particularly, Leavitt discloses that the insecticidal composition, which is preferably utilized as an aerosol sprayable composition, comprises a so-called “substantially non-aqueous" mixture, which is said to include a toxic concentration of a vaporizable insecticide as well as a so-called “substantially inert” foam-forming carrier. After this insecticidal composition is dispensed from its aerosol spray container, the foam-forming carrier is said to form a so-called “stable” (i.e. a form-sustaining) foam. Leavitt further discloses that the insecticide is released from such a foam carrier in toxic concentrations at a controlled rate over a prolonged period of time.
  • U.S. Pat. No. 3,970,584 to Hart et al. discloses a personal-care foam-forming emulsion that is utilized to produce a rich, creamy, shiny foam having a so-called "fine” or "delicate bubble” structure.
  • Hart et al. teach that such a foam can be utilized to produce a variety of personal-care types of products.
  • Hart et al. specifically teach that such a rich, creamy, shiny foam can be utilized to produce an insect-repellent personal-care type of product.
  • Hart et al. further specifically teach that their personal- care type of foam products can have certain unique characteristics which, in turn, are said to be particularly desirable in the personal-care field.
  • Hart et al. point out that their foam product will have a so-called "fine” or “delicate” bubble structure, and that such a foam product will, as a result, possess desirable foam-density and foam-stiffness personal-care types of qualities.
  • German Pat. (“Offenlegungsschrift”) No. 25 38 470 discloses a method for producing a pesticidally-active composition-of-matter, characterized as an attractant in admixture with a toxicant, wherein the composition-of-matter is produced by a method whereby the attractant and toxicant are absorbed into a piece of plastic foam by so-called "electrostatic" forces.
  • U.S. Pat. No. 3,076,744 to Geary discloses a particular insecticidal bait composition, which is said to include a so- called “polymerized aminoplast” and an insect-edible attractant in admixture with an organic insecticide.
  • the attractant and the insecticide are said to be "molecularly occluded” within the polymerized aminoplast.
  • Geary further discloses that the polymerized aminoplast, containing the above-mentioned "occluded” ingredients, can be crushed to a fine-particle size and thereafter spread, for example, in insect-infested areas.
  • U.S. Pat. No. 3,791,983 to Maierson discloses certain sprayable and so-called “aerosolizable" web-forming compositions. Such compositions, in particular, are characterized as being self-supporting, three-dimensional webs of randomly-associated, joined monofilaments ranging in average diameter of from about 1 to 10 microns.
  • compositions of this sort are said to be utilizable for the purpose of encapsulating insecticidal ingredients. Insecticidal ingredients thus encapsulated can then be used to combat insects.
  • U.S. Pat. No. 4,286,020 to Hi el et al. also discloses a process for the encapsulation of certain insecticidal particles.
  • British Pat. No. 1,107,140 to Mitchell et al. discloses an insecticidally-active oil-in-water emulsion which, after being dispensed from an aerosol-type dispenser, preferably is so formulated as to produce a spray rather than a foam.
  • present-day consumers nevertheless continue to seek ever novel pesticidal compositions-of-matter for a variety of reasons. For example, easy clean-up or disposal of a variety of now- inactive pesticidal products is desirable.
  • Pesticidally- active compositions are of course known, in general, to possess a finite activity period. To facilitate clean-up of compositions rendered pesticidally-inactive due to the passage of time, it would be desirable that such a pesticidally-active composition be water-soluble.
  • novel pesticidally-active composition-of-matter is characterized as a stable foam matrix.
  • the foam matrix can so be formulated as to be substantially stable for hours or weeks (or even months) , as desired.
  • my novel composition-of-matter is water-soluble, a markedly desirable characteristic and/or quality (or feature) , which enables easy clean-up and/or disposal of the composition, after it is rendered inactive due to the passage of time.
