Definitions

  • the present invention relates to a method of dispersing airborne active components and, in particular, to fragrances and insect repellants dispersed from an aerosol spray device.
  • Dispersion of an active components from an aerosol spray device is not ideal as the active component generally only has an effect within the direction of the line of spray. This is due to the design requirements for an aerosol spray device which can deliver a spray over a reasonable distance.
  • the design of the spray head of conventional aerosol spray devices results in the emission of a spray with a small spread angle, that is to say, most of the spray travels at least initially along or close to a central spray line extending from the spray head.
  • the spray is to be delivered over a considerable spatial volume, including space which has a substantial lateral radiation having regard to its centerline, a large amount of aerosol spray must be delivered in order to ensure that the active component, such as a fragrance or insect repellant, reaches throughout the target space .
  • the active component such as a fragrance or insect repellant
  • a method of improving the dispersion of an airborne active component comprises directing into a space in which the active component is to be dispersed liquid droplets from a spray device containing a composition containing the active component, a unipolar charge being imparted to the said liquid droplets by double layer charging during the spraying of the liquid droplets from the spray device, the unipolar charge being at a level such that the said droplets have a charge to mass ratio of at least +/- 1 x 10 "4 C/kg.
  • the composition which is dispersed according to the method of the invention may be a fragrance composition or an insect repellant .
  • the fragrance composition which is dispersed according to the present invention contains at least one fragrance component .
  • fragrance components are diethylphthalate, orange terpenes (limonene) , styrallyl acetate ester, Cyclacet, methyl ionone ketone, vanillin, itsea Cybeba, 2-phenylethan- l-ol, dipropylene glycol and -methyl-p-3°-butyl hydrocinnamic a1dehyde .
  • the unipolar charge which is imparted to the liquid droplets is generated solely by the interaction between the liquid within the spray device and the spray device itself as the liquid is sprayed therefrom.
  • the manner in which a unipolar charge is imparted to the liquid droplets does not rely even partly upon the connection of the spray device to any external charge including device, such as a source of relatively high voltage, or any internal charge inducing device, such as a battery.
  • the spray device is entirely self- contained making it suitable for use both in industrial, institutional and domestic situations.
  • the spray device is a domestic pressure-spraying device devoid of any electrical circuitry but which is capable of being hand held.
  • Such a device has a capacity in the range of from 10ml to 2000ml and can be actuated by hand, or by an automatic actuating mechanism.
  • a particularly preferred domestic device is a hand-held aerosol can.
  • the droplet charge to mass ratio of at least +/- 1 x 10 "4 C/kg is imparted to the liquid droplets as a result of the use of an aerosol spray device with at least one of the features of the material of the actuator, the size and shape of the orifice of the actuator, the diameter of the dip tube, the characteristics of the valve and the formulation of the fragrant composition containers within the aerosol spray device being chosen in order to achieve the said droplet charge to mass ratio by double layer charging imparting the unipolar charge to the droplets during the actual spraying of the liquid droplets from the orifice of the aerosol spray device.
  • a volume of space to be treated such as the interior of a room
  • an aerosol composition such as a room spray
  • more effective fragrancing of a room can be obtained using a fragrance composition, and more effective dispersion of an insect repellant using an insect repellant composition.
  • This result is achieved because of the unipolar charge imparted to the liquid droplets of the aerosol spray. This charge has two effects. Since all of the droplets carry the same polarity charge, they are repelled one from another.
  • the liquid composition which is sprayed into the air using the aerosol spray device is preferably a water and hydrocarbon mixture, or emulsion, or a liquid which is converted into an emulsion by shaking the spraying device before use, or during the spraying process.
  • a typical aerosol spray device comprises :
  • An aerosol can containing the composition to be sprayed from the device and a liquid or gaseous propellant
  • a dip tube extending into the can, the upper end of the dip tube being connected to the valve ;
  • a preferred aerosol spray device for use in the present invention is described in WO 97/12227. It is possible to impart higher charges to the liquid droplets by choosing aspects of the aerosol device including the material, shape and dimensions of the actuator, the actuator insert, the valve and the dip tube and the characteristics of the liquid which is to be sprayed, so that the required level of charge is generated as the liquid is dispersed as droplets.
  • a number of characteristics of the aerosol system increase double layer charging and charge exchange between the liquid formulation and the surfaces of the aerosol system. Such increases are brought about by factors which may increase the turbulence of the flow through the system, and increase the frequency and velocity of contact between the liquid and the internal surfaces of the container and valve and actuator system.
  • characteristics of the actuator can be optimised to increase the charge levels on the liquid sprayed from the container.
  • a smaller orifice in the actuator insert, of a size of 0.45mm or less, increases the charge levels of the liquid sprayed through the actuator.
  • the choice of material for the actuator can also increase the charge levels on the liquid sprayed from the device with material such as nylon, polyester, acetal, PVC and polypropylene tending to increase the charge levels.
  • the geometry of the orifice in the insert can be optimised to increase the levels on the liquid as it is sprayed through the actuator. Inserts which promote the mechanical break-up of the liquid give better charging.
  • the actuator insert of the spray device may be formed from a conducting, insulating, semi-conducting or static-dissipative material.
  • the characteristics of the dip tube can be optimised to increase charge levels in the liquid sprayed from the container.
  • a narrow dip tube of for example about 1.27mm internal diameter, increases the charge levels on the liquid, and the dip tube material can also be changed to increase charge.
  • Valve characteristics can be selected which increase the charge to mass ratio of the liquid product as it is sprayed from the container.
  • a small tailpiece orifice in the housing of about 0.65mm, increases product charge to mass ratio during spraying.
  • a reduced number of holes in the stem for example 2 x 0.50mm, also increases product charge during spray.
  • the presence of a vapour phase tap helps to maximise the charge levels, a large orifice vapour phase tap of, for example, about 0.50mm to 1.0mm generally giving higher charge levels.
  • a formulation containing a mixture of hydrocarbon and water, or an emulsion of an immiscible hydrocarbon and water, will carry a higher charge to mass ratio when sprayed from the aerosol device than either a water alone or hydrocarbon alone formulation.

  • An orifice 27 (not shown in Figure 1) is provided in the wall of the tailpiece 8 and constitutes a vapour phase tap whereby the gas pressure in the reservoir 2 can act directly on the liquid flowing through the valve assembly.
