Patented Apr. 4, 1944 2,345,904 SYNERGISTS T AEROSOL INSECTICIDES William N. Sullivan, Washington, D. 0., and Lyle D. Goodhue, Berwyn, Md., assignors to the United States of America as represented by Claude R. Wickard, Secretary of Agriculture, and his successors in oflice No Drawing. Original application September 30,
1941, Serial No. 412,960.
Divided and this application January 7, 1944, Serial No. 517,371
(Granted under the act of March 3, 1883, as
amended April 30, 1928; 370 0. G. 757) 3 Claims.
This application is made under the act of March 3, 1883, as amended by the act of April 0 30, 1928, and the invention herein described and claimed, if patented, may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment to us of any royalty there- This is a division of our copending application for patent, Serial No. 412,960, filed September 30, 1941. a I Our invention relates to materials which will increase the effectiveness of insecticides in aerosol form. 1
Certain agents which may or may not be toxic in themselves when added to aerosol insecticides greatlyincrease the rate of mortality. The increased toxicity obtained by the combination of such materials is often referred to as synergism and the added material a synergist. Therefore, in these terms, the general object of our invention is the provision of materials suit able as synergists for aerosol insecticides.
Another object of our invention is the provision of agents which will not only increase the insecticidal action of materials known 'to possess some toxicity, but, which will also impart insecticidal properties to materials which are known to be non-toxic or to have a very low toxicity.
A further object of our invention is the provision of such agents acting as synergists, which can be applied by dispersion simultaneously with and by the same methods used for the preparation of aerosol insecticides.
We have found that materials suitable for the purposes of this invention belong most frequently to the class of chemical compounds which I are surface active in non-aqueous solvents or production can be used with different types of synergists. In this class of chemical compounds we have found the fatty acids, the ,mono esters of fatty acids and ethylene or propylene glycol, of glycerine or sorbitol, to be especially suitable as well as fatty acids in combination with atnines such as methanolamine, ulfonated aryl]and alkyl 1 radicals alone or combined with an amine,"
There are many processes which can be used to apply these materials in thef-form of aerosols; such as spraying into the atmosphere f vaporizae tion, by chemical reaction, byspraying on a heated surface, and so forth. Although this} invention is not limited to any particular method of application, our preferred *method of/ application comprises dissolving the synergist in the; insecticide, if the insecticide is a liquid, or dissolving it in some solvent common to'- both if a solid, and spraying the solutionon a heated surface, whereby an aerosol is formed composed of both the synergist and the insecticide.
, A synergist to an insecticide in aerosolform is not necessarily also a synergist to an insecticide in spray form, even of the same compound. Actual tests have disclosed that an agent which possesses little or no effect as a synergist to an insecticidal spray may be extremely effective as a synergist to an insecticidal aerosol. The rea son for this is not apparent, but it would seem that the mere wetting of the insect cannot explain the action.
The following results were obtained using synergists in accordance with this invention. These results were obtained on the basis of preliminary tests first carried out in a small chamber of '7 cu. ft. and then on a larger scale in a 216 cu. ft. chamber. In each test from 500 to 600 files were used. Six-tenths of a pound of o-dichlorobenzene per 1000 cu. ft. gave only a 2% kill. However, when mixed with 0.16 lb. of oleic acid as a synergist, a kill was obtained. This same quantity of oleic acid, when used alone under the same conditions gave only a 1% kill. Lauric acid when used alone inthe same amount, namely, 0.16 lb. per 1000 cu. it, gave only a 1% kill, but. when used as a synergist with 0.6 lb. of o-diclilorobenzene per 1000 cu. it. a kill was obtained.
The same synergists were tested at other concentrations and it was found that little is gained by adding more than 10%.
The following is a list of substances which were tested as synergists at a concentration of 0.06 lb. in 0.6 lb. of o-dichlorobenzene per 1000 cu. it. against the housefly, the percentage of kill in each case being indicated in the right hand column:
Percent kill Spermaceti 37 Diglycol laurate 48 Sulfonated naphthalene 60 Salicylic ac 91 Propylene glycol oleate 28 Myristic ac 49 Propylene glycol laurate 74 Sorbitol laurate .59 Monoglycol laurate .56 Triethanolamine oleate 56 Lauryl sulfate 70 Other insecticides were used against the American and German cockroach at a concentration ways less than 100% and usually less than 50%.
In a 1100 cu. ft. room, naturally infested with cockroaches, more than 5000 were killed in 18 hours and none were found living, using 1 /2 lbs. of o-dichlorobenzene with 3% lauric acid and 2% oleic acid. Excellent results were also obtained in a 3200 cu. ft. room.
Tests were also conducted against the carpet beetle larva, the confused flour beetles and crickets. The halogenated esters in combination with any one of the synergists mentioned above are extremely toxic to the confused flour beetle and produce a high mortality to the carpet beetle larva.
Among 80 compounds tested against the housefly in the form of aerosols, in combination with synergists of the type mentioned above, are 3- chloroacenaphthene, Z-chlorofluorene, 3-chlorodibenzofuran, chlorinated diphenyls, halogenated naphthalenes, halogenated esters, halogenated ketones, carbazole, thiocresol and halogenated phenols. The synergist was shown to be responsible in each case for an increase in toxicity.
Having thus described our invention, we claim: 1. An insecticide in aerosol form comprising 3- chlorodibenzofuran and an agent chosen from the group consisting of dlglycoi laurate, propylene glycol oleate, propylene glycol laurate, sorbitol laurate, and monoglycol laurate.
2. An insecticide in aerosol form comprising 3- chlorociibenzofuran and sulionated naphthalene.
3. An insecticide in aerosol form comprising 3- chlorodibenzofuran and lauryl sulfate.
