Definitions

  • the present invention concerns an aerosol insecticide composition which is particularly suitable for use on aircraft.
  • Many countries have quarantine regulations which require incoming or outgoing aircraft to be treated with an aerosol insecticide. This is to prevent the spread of unwanted insects or of human, veterinary and agricultural vector-born diseases around the world, and into countries like Australia where such diseases can do great harm.
  • Suitable aerosols which are allowed to be used for aircraft disinsection have been recommended by a World Health Organization (WHO) committee.
  • Suitable aerosols include the active ingredients of resmethrin, bioresmethrin, phenothrin and permethrin. These are dispensed from a pressurised container by means of the inclusion of an aerosol propellant.
  • These propellants have traditionally been chlorofluorocarbons (CFCs).
  • Commonly used propellants are 1:1 mixtures of dichlorodifluoromethane (Freon 11), and trichlorofluoromethane (Freon 12).
  • AQIS Australian Quarantine and Inspection Service
  • the present invention therefore provides an aerosol insecticidal composition suitable for use on aircraft, which comprises a dispensing container having aerosol dispensing means, and containing an insecticidal active ingredient, optionally a solvent for the active ingredient, and a propellant gas at a sufficient pressure to dispense the active ingredient from the dispensing means as an aerosol, characterised in that the solvent (if present) is chosen from any one or more of an alcohol, water, or a hydrocarbon such as kerosene, and the propellant is chosen from any one or more of CF-CH j F, DME, C0 2 , or NO,.
  • the solvent if present
  • the propellant is chosen from any one or more of CF-CH j F, DME, C0 2 , or NO,.
  • One preferred embodiment of the invention concerns the aerosol insecticidal composition
  • the solvent if used
  • the propellant is CF-CH.XF-
  • the preferred CF-CH 2 F propellant is HFC 134a (1,1,1,2-tetra-fluoroethane) .
  • the propellant maybe a mixture of DME and either CO- or 0 2 - Otherwise a solvent such as an alcohol and/or water may be used with C0 2 as the propellant. As a further alternative the solvent can be a mixture of alcohol and water together with DME and C0 2 as the propellant.
  • propellants such as CO, or N0 2 can be used in conjunction with CF,CH 2 F.
  • the insecticidal composition should meet WHO standards. These standards can be obtained from WHO Weekly Epide . Rec. (7) 1985 pp.45-47 entitled, "Recommendations on the disinsecting of aircraft". In summary, these recommendations require that the dispenser should discharge the formulation as an aerosol at the rate of 1.0 ⁇ 0.2g per second, and the aerosol produced must comply with various physical requirements; for example, not more than 20% by weight of the aerosol should consist of droplets of a diameter greater than 30 micron and not more than 1% by weight of the aerosol should consist of droplets of a diameter greater than 50 micron.
  • the insecticidal activity of the aerosol produced from its dispenser cannot be inferior to that of the standard reference aerosol having the following formulation: trichlorofluoromethane 42.5% pyrethrum extract (25% pyrethrins) 1.6%
  • the formulation should cause no residual risk to the aircraft structure or operating equipment, and for there to be no risk of fire. Therefore a very low flammability, and a suitable inertness of the composition is highly desirable.
  • the insecticide used should not be dangerous to humans.
  • the insecticide will normally be in a standard dispensing container of the type already used for aircraft. As well as disinsecting the aircraft cabin, the baggage and cargo holds should also be treated. This is often done by the pilot releasing the insecticide in a one-shot container, by remote control, on landing, or before taking off, whereby the insecticide is spread throughout the cargo hold of the aircraft.
  • the insecticide may be released in the passenger cabin either manually by airline stewards spraying the insecticide, or by remote control into the air conditioning system in the aircraft cabin.
  • Suitable insecticides include resmethrin, bioresmethrin, d-phenothrin and/or permethrin (25:75 cis/trans ratio).
  • a suitable mixture of insecticides is permethrin (25:75) in an amount of 2% by weight and d-phenothrin (20:80), also in an amount of 2% by weight. Otherwise each of the preferred insecticides; permethrin (25:75), or d-phenothrin (20:80), may be used alone. These insecticides are available from Roussel Uclaf, for example.
  • the remainder of the contents of the dispensing container will comprise mostly propellant, but may also contain an amount of solvent to dissolve the insecticide, and allow it to be easily dispensed as an aerosol.
  • the presence of a solvent also assists to ensure that all the active ingredient is dispensed from the container into the aircraft, ana to assist the insecticidal activity of the active ingredients.
  • the formulation for cargo holds will normally contain 4% of the two preferred active ingredients, and 8% of solvent.
  • the formulation for use in the passenger compartment will normally containa single active ingredient in an amount of 2%, and 10% of solvent.
  • HCF 134a as the propellant gas with a paraffinic hydrocarbon such as kerosene (“Exxsol”), isoparaffins (“Isopar”) or normal paraffins (“Norpar”) as a solvent; a preferred such solvent being "Exxsol D80” or one selected from Isopar, white spirit and the like.
  • a paraffinic hydrocarbon such as kerosene (“Exxsol”), isoparaffins (“Isopar”) or normal paraffins (“Norpar)
  • solvents are available form Exxon Chemicals, for example.
  • the solvent should be present in an amount of less than about 12% (by weight), ideally about 8% to 10%. If 4% by weight of the composition is active insecticidal ingredients, then the 134a propellant can be present in an amount of about 88% by weight.
  • the container is then pressurised, to a pressure of about 100 psi.
  • the minimum pressure in the can should be at least 60 psi, at normal pressures.
  • the dispensing container is preferably an aluminium monoblock can.
  • the dispensing means can be a one-shot type, whereby on activation the complete contents of the can are expelled. Alternatively, the dispensing means can allow a limited amount of the aerosol to be expelled at a time. A combination of one shot and controllable dispensing is also allowed in accordance with the invention.
  • the can may be lined, if desired, with a lining to prevent corrosion, and leakage.
  • the ingredients may be added to the container in any appropriate order, in accordance with usual practice in producing aerosol products. Any suitable size may be used, but a can of a suitable dimension to be usable in existing release mechanisms that are installed on aircraft is preferred. Cans of 75g and 150g (filled) are suitable, for instance.
  • ingredients may be added to the formulation, in small quantities, if desired.
  • Such ingredients include corrosion inhibitors, pH buffers, perfume, and so on. Suitable such ingredients chosen from the prior art may be used in this instance.
  • the aerosol composition contains 4% active ingredient, an amount of paraffinic hydrocarbon solvent for the active ingredient(s) , such as deodorised kerosene, in an amount of up to about 8% by weight, and as a propellant gas, 134a, (1,1,1,2-tetra-fluoroethane) .
  • the composition may contain 2% of a single active ingredient and 10% of solvent.
  • 134a is a propellant which does not have the environmental dangers previously known for CFCs, and is therefore advantageously used for dispensing aerosols in aircraft.
  • the present invention concerns aerosol compositions for use other than in aircraft, but which advantageously share the same requirements with aerosols used in aircraft.
  • such aerosols can be used in the home as one-shot aerosols for dispensing insecticide throughout a room, when the human inhabitants are not present.
  • the aerosol composition with 134a as the propellant may be used with methoprene as the active insecticidal ingredient, as a one-shot process for treating homes or rooms for dust-mites.
  • personal insecticidal compositions for spraying directly on human skin can utilize the compositions of the present invention.
  • the invention also involves a method of de-insecting aircraft which comprises spraying the cargo holds and/or passenger compartments with an aerosol insecticidal composition referred to above immediately before departure and/or before arrival of said aircraft at an airport.
  • Example la An aerosol formulation is prepared comprising 2% d-phenothrin and 2% permethrin. An amount of 34% DME is added to the formulation, as well as 2% of a corrosion inhibitor. To the container is added water so that the 450 ml can is approximately 40% full of liquid. C0 2 is added to increase the pressure to approximately 100 psi.
  • Example lb The same formulation described in example la is prepared, but instead 20% by weight of DME is added.
  • Example lc 2% each of two different pyrethroid insecticides selected from resmethrin, bioresmethrin, d-phenothrin and permethrin (cis/trans ratio 25/75) are added to a 150 ml monoblock can.
  • a sufficient amount of a mixture of methylated spirits and water is added until the volume comprises about 40% of the can.
  • C0 2 is charged into the container to a pressure of at least 60 psi, and preferably 100 psi.
  • Example 2 An aerosol formulation is prepared comprising 2% by weight of d-phenothrin (trade name “Sumithrin”) and 2% permethrin (25/75 cis/trans ratio). The active ingredients are dissolved in a solvent consisting of deodorised kerosene (trade name “EXXSOL D80"). The solvent constitutes about 8% by weight of the formulation. The dispensing container is then charged with propellant comprising CF 3 CH 2 F (134a) to a pressure of about 80 psi. If desired, a corrosion lining can be incorporated in the dispensing container, to assist with preventing leaks. This aerosol is ideal for use in cargo and baggage holds of aircraft.
  • Example 3 An aerosol formulation is prepared comprising 2% by weight of permethrin (25:75 cis/tra ⁇ s ratio). The active ingredient is dissolved in a solvent consisting of isoparaffins "Isopar”. The solvent constitutes about 10% by weight of the formulation. The dispensing container is then charged with propellant comprising CF 3 CH 2 F (134a) to a pressure of about 80 psi. If desired, a corrosion lining can be incorporated in the dispensing container, to assist with preventing leaks. This formualtion is ideal for spraying in passenger cabins of aircraft.
  • Example 4 Further aerosol formulations were prepared in a similar manner to that described in Example 3, but as the active pesticidal ingredients were used the following: amount (by weight) 2% 2% 2% 2% 2%
  • Example 5 A preferred composition according to the invention was tested using the following procedure. Trials were conducted on domestic legs of a British Airways B747-400s aircraft on a return flight between Sydney and Brisbane. Ten rust red flour beetles (Tribolium castaneum) were placed in plastic cups in which the base had been removed and replaced with insect secure mesh. The cups were placed in wire retainers at various positions in the forward and afterward (aft) holds. Since the cups were open at the top and had a mesh base, air movement past the beetles was relatively unimpeded. Insects were also held in sealed cups inside plastic bags to ensure that extraneous factors were not the cause of the observed insect reaction (controls).
  • Tribolium castaneum Tribolium castaneum
  • the cages were installed before the cargo was loaded and retrieved after the flight which had a duration of about 75 minutes. An attempt was made to maintain the same cage on both flights but loading constraints limited the extent to which this was possible. The cage positions in the forward and afterwards holds on the flights were distributed evenly.
  • the residual insecticide effect of the formulation is an important component in the overall effectiveness of the formulation as it forms an insecticidal active surface to which insects, which were not immobilised by the initial spray, would be exposed during the flight.
  • the currently used formulation discharges at a rate of 4 g/s and it is preferred that the HCF 134a formulation should be discharged at a similar rate.
