Abstract
An insect repellent master batch composition for incorporation into a plastics matrix, comprises a polymer base and up to 20% by weight of eucalyptus maculate citriodora, such as Citrepel (RTM), and at least five other fragrance oils selected from bergamot oil, eucalyptus oil, lavendin oil, geranium oil, tea tree oil, clover oil, niaouli oil, peppermint oil, basil oil, each of the other oils being present in the master batch at a proportion less than 1%, the balance being made up of the polymer base. Preferably, the polymer base is ethylene vinyl acetate copolymer. Isopropyl myristate may be added as a fixative to slow down the rate of dissipation of the fragrances. A plastics article made by the method may have a concentration of between 5% and 1% Citrepel (RTM) in the finished article, which may be a refuse sack.
Description
Insect Repellent This invention relates to an insect repellent composition, to be incorporated in a plastics matrix to give products made from the plastics matrix insect repellent properties.
In particular, the composition may be used in plastics intended to be made into refuse sacks, and the invention extends to refuse sacks incorporating such a composition.
According to the invention, there is provided an insect repellent master batch composition for incorporation into a plastics matrix, the composition comprising a polymer base and up to 20% by weight of eucalyptus maculata citriodora * *:. (preferably in the form of an oil sold by Chemian Technology Limited of Darlington under the trade mark Citrepel 75) and at least five other fragrance oils selected **** from the following list: bergamot oil, eucalyptus oil, lavendin oil, geranium oil, tea tree oil, clove oil, niaouli oil, peppermint oil, basil oil, each of the other oils being present in the maser batch at a proportion less than 1%, the balance being made up of the polymer base.
According to a second aspect of the invention, there is provided an insect repellent master batch composition for incorporation into a plastics matrix, the composition comprising a polymer base and up to 20% by weight of fragrant oils selected from the following list: bergamot oil, eucalyptus oil, lavendin oil, geranium oil, tea tree oil, clove oil, niaouli oil, peppermint oil, basil oil, and eucalyptus maculata citriodora (the latter preferably in the form of an oil sold by Chemian Technology Limited of Darlington under the trade mark Citrepel 75) wherein each of the foregoing oils, with the exception of eucalyptus maculata citriodora is present in a quantity by weight of less than I %, the balance being made up of the polymer base.
Isopropyl Myristate can be added as a fixative to slow down the rate of dissipation of the fragrances.
The polymer base is preferably an ethylene vinyl acetate copolymer which has been found to be suitable for accepting additions of fragrance oils while allowing the polymer base to remain homogenous. The grade of EVA copolymer should be chosen such that the oils blend into the polymer without significantly disrupting the polymer structure and do not sweat out of the polymer.
The master batch is made by mixing the required quantity of oils with the copolymer under elevated temperature conditions such that the oils are absorbed into the co-polymer. The polymer mixture is then extruded and the extrudate fed :. to a granulator to form the master batch produce into granules. The master batch * granules will then be added to a raw plastics feed to an extruder or moulding machine or the like. Typically the extruder, moulding machine or the like will be fed with a batch of raw plastics of which the master batch will be between about 3.5 % to 7 % by weight of the total. Thus a 500kg master batch will be added to between 15,000 and 7,500 kg of raw plastics.
The applicants aim to achieve a concentration of between 5% and 1 % of Citrepel in the finished product manufactured from plastics to which the master batch has been added. the final concentration may vary depending on the degree of insect repellence required which may, for example, be different in different climates.
The master batch will be added to a larger body of plastics material in a plastics processing plant, mixed with the body of plastics, melted with the plastics so that the master batch is evenly distributed within the larger body of plastics which is then extruded, moulded to other wise processed to produce a finished plastics product. The finished product will benefit from the addition of the fragrant oils and, by using the master batch described here, will have insect repellent properties.
A particularly important use for the master batch is in the manufacture of refuse sacks as regular refuse sacks, when filled with organic refuse and left to stand, attract flies and other insects.
The present invention thus extends to refuse sacks made from a plastics mix to which a master batch in accordance with the invention has been added.
Clearly other products can be manufacture using the master batch
Example:
:... The following master batch composition has proved effective * * Citrepel 75 12.5 kilos : *.. bergamot oil, 10.0 kilos :. 15 eucalyptus oil. 10.0 kilos lavendin oil, 10.0 kilos geranium oil, 10.0 kilos tea tree oil, 10.0 kilos *. clove oil, 10.0 kilos niaouli oil, 10.0 kilos peppermint oil, 10.0 kilos basil oil, 10.0 kilos EVA copolymer 442.5 kilos This mix is designed to produce 500 kg of product master batch. There are small losses of vapour from hot material as the mixture is extruded before cooling.
Those skilled in the art of producing polymer master batches will be able to develop suitable processes for blending the oils into the polymer base.
The applicants have used Citrepel 75 in their development of this invention, and understand the active ingredient of Citrepel 75 to be eucalyptus maculata citriodora. The identification of eucalyptus maculata citnodora. as the active ingredient is made to the best of the inventors' knowledge. and if incorrect, the applicants claim whatever active ingredient is present in Citrepel 75.
