Stable toxicant compositions comprising a toxicant and a Castor Oil based nonionic surfactant containing from about 5 to about 55 moles of ethylene oxide chemically combined with each mole of Castor Oil.

Stable tocicant compositions of chlorpyrifos

Pure 2-(4-isobutylphenyl)propionic acid and related compounds are obtained in good yield by a multi-step process comprising chloromethylation of benzene or an alkylbenzene, conversion of the resulting benzyl chloride to the cyanide, alkylation of that product to the phenylpropionitrile or phenylbutyronitrile, reaction of unreacted benzyl cyanide with an aldehyde to inhibit its hydrolysis, and hydrolysis of the nitrile to the free acid. The products are antiinflammatory, antipyretic, and analgesic drugs.
