Abstract: Paints, water paints, lacquers, varnishes, enamels, staining preparations and polishing waxes have incorporated in them an insecticidal ingredient consisting of a compound of the general formula <FORM:0606266/III/1> wherein R-CO represents the radical of an aliphatic, cyclo-aliphatic, aromatic or araliphatic mono-carboxylic acid, R1 is hydrogen or an alkyl radical, R2 is hydrogen or a methyl group, and R3 is hydrogen, an aliphatic radical, or halogen.  According to examples, a wood stain comprises a fat soluble dyestuff and g -propenyl-o-chlorobenzoate dissolved in solvent naphtha; a varnish stain comprises rosin, button lac and g -propenyl benzoate dissolved in methylated spirit; and a water paint is made by dissolving g -propenyl-p-chlorobenzoate in the oil portion of the paint prior to emulsification.ALSO:An insecticidal composition comprises a compound of the general formula <FORM:0606266/VI/1> wherein R-CO represents the radical of an aliphatic, cyclo-aliphatic aromatic or araliphatic monocarboxylic and, R1 is hydrogen or an alkyl radical R2 is hydrogen or a methyl group, and R3 is hydrogen, an aliphatic radical or halogen.  Specified compounds are the g -propenyl esters of benzoic, o-chlorobenzoic, p-chlorobenzoic, m-p-dichlorobenzoic, m-nitrobenzoic, salicylic, o-anisic, cresotinic, phenoxyacetic, o-p-dichlorophenoxyacetic, o-chlorophenyl-chloracetic, p-chlorophenylchloracetic, cinnamic, o-chlorocinnamic and p-chloricinnamic acids and the compounds named in Specification 604,443.  Other ingredients in the composition may be solvents such as kerosene, solvent naphtha benzene, white spirit, olive oil, toluene, cyclohexanone, a mixture of benzene and methyl cyclohexanol, carbon tetrachloride and trichloroethylene, solvents which boil below room temperature at atmospheric pressure, aqueous emulsifying liquids, solid combustible carriers which will produce an aerosol on ignition and the ingredients of paints, lacquers, varnishes, enamels, staining preparations and polishing waxes.  Examples describe solutions of g -propenyl-o-chlorobenzoate in carbon tetrachloride or tri-chloroethylene; an emulsion prepared by dissolving g -propenyl p-chlorobenzoate in a mixture of benzene and methyl cyclohexanol, stirring in sulphonated castor oil and ammonia and diluting the mixture with water; a solution of g -propenyl m-nitrobenzoate in white spirit; a mixture of carnauba wax, paraffin wax, white spirit and g -propenyl m-p-dichlorobenzoate; a solution of g -propenyl salicylate in olive oil; a bath made by dissolving stearyl tolyl di-ethyl ammonium etho-sulphate and g -propenyl p-chlorobenzoate in tuluene and pouring the resulting solution into water; impregnating sawdust with an aqueous suspension prepared by mixing g -propenyl m-p-dichlorobenzoate, china clay and a wetting agent and suspending the resulting powder in water; a solution of g -propenyl o-pdichlorophenoxyacetate in benzene; a solution of g -propenyl o-anisate in kerosene; a solution under pressure containing g -propenyl salicylate, cyclohexanol, lubricating oil and difluorodichloromethane; and an ignitable composition containing g -propenyl m-p-dichlorobenzoate and potassium nitrate packed on a cardboard shell and provided with an igniter impregnated with "solidified petrol.  Specification 603,428, [Group VIII], also is referred to.
