Definitions
- the general object of our invention is the provision of materials suitable 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 sion 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.
- materials suitable for the 10 Our invention relates to materials which will synergists.
- fatty acids and ethylene or propylene glycol, of glycerine or sorbitol to be especially suitable as well as fatty acids in combination with amines such as methanolamine, sulfonated aryl and alkyl radicals alone or combined with an amine.
- a synergist to an insecticide in aerosol form 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 reason for this is not apparent, but it would seem that the mere wetting of the insect cannot explain the action.
- ammonium or the sulfonic acid, alone, in multiple, or in combination, which is attached to some long chain aliphatic radical, or, in some cases, an aromatic radical.
- Substances acting as detergents or surface active agents in non-aqueous media can be easily applied by the usual methods of aerosol production, but this invention is not limited to these, substances because different methods of aerosol production can be used with different types of quantity of oleic acid, when used alone under the same conditions gave only a 1% kill.
- a mortality of 100% was obtained with the following: methyl chloroacetate plus lauric acid, epichlorohydrin plus lauric acid, epichlorohydrin plus 'oleic acid, ethyl dichloroacetate plus lauric acid, ethyl dichloroacetate plus oleic acid, beta-chloroethyl chlorocarbonate plus lauric acid, beta-chloroethylacetate plus lauric acid, tetrachloroethane plus lauric acid, and o-dichlorobenzene plus lauric acid.
- lauric acid was also found to be effective and vice versa.
- the kill without a synergist was always less than 100% and usually less than 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% lbs. of o-dichlorobenzene with 3% lauric acid and 2% oleic acid. Excellent results were also obtained in a 3200 cu. ft. room.
- An insecticide in aerosol form comprising carbazole and salicylic acid.
- An insecticide in aerosol form comprising thiocresol and salicylic acid.
- An insecticide in aerosol form comprising 3-chlorodibenzofuran and salicylic acid.

increase the effectiveness of insecticides in aerosol form.
Certain agents which may or may not be toxic in themselves when added to aerosol insecticides greatly increase the rate of mortality. The in-- creased to'xicity 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 suitable 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 sion 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 10 Our invention relates to materials which will synergists. In this class of chemical compounds fatty acids and ethylene or propylene glycol, of glycerine or sorbitol, to be especially suitable as well as fatty acids in combination with amines such as methanolamine, sulfonated aryl and alkyl radicals alone or combined with an amine.
There are many processes which can be used to apply these materials in the form of aerosols, such as spraying into the atmosphere, vaporization, by chemical reaction, by spraying 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 solution on a heated surface, whereby an aerosol is formed composed of both the synergistand the insecticide.
A synergist to an insecticide in aerosol form 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 reason 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 alarger scale in a 216 cu. ft. chamber. In each test from 500 to 600 flies 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 olelc acid as a. synergist,.a 55% kill was obtained. This same purposes of this invention belong most frequently to the class of chemical compounds which are surface active in non-aqueous solvents or which act as detergents in non-aqueous solvents. These compounds, in general, contain polar groupings such as the hydroxyl, the carboxyl, the amine, the
ammonium, or the sulfonic acid, alone, in multiple, or in combination, which is attached to some long chain aliphatic radical, or, in some cases, an aromatic radical.
Substances acting as detergents or surface active agents in non-aqueous media can be easily applied by the usual methods of aerosol production, but this invention is not limited to these, substances because different methods of aerosol production can be used with different types of quantity of oleic acid, when used alone under the same conditions gave only a 1% kill. Lauric acid when used alone in the same amount, namely, 0.16 lb. per 1000 cu ft., gave only a 1% kill, but when used as a synergist, with 0.6 lb. of o-dichlorobenzene per 1000 cu. ft. 2. 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 Other insecticides were used against the American and German cockroach at a concentration of 1.5 lbs. per 1000 cu. ft. One-tenth of the insecticide was replaced by a synergist. A mortality of 100% was obtained with the following: methyl chloroacetate plus lauric acid, epichlorohydrin plus lauric acid, epichlorohydrin plus 'oleic acid, ethyl dichloroacetate plus lauric acid, ethyl dichloroacetate plus oleic acid, beta-chloroethyl chlorocarbonate plus lauric acid, beta-chloroethylacetate plus lauric acid, tetrachloroethane plus lauric acid, and o-dichlorobenzene plus lauric acid. In all cases where oleic acid was effective, lauric acid was also found to be effective and vice versa. The kill without a synergist was always less than 100% and usually less than 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% 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, 2-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 carbazole and salicylic acid.
2. An insecticide in aerosol form comprising thiocresol and salicylic acid.
3. An insecticide in aerosol form comprising 3-chlorodibenzofuran and salicylic acid.
