Abstract
Abstract Textiles are impregnated with insect repellent compositions including piperonyl butoxide and pyrethrin, wetting agent, thickener and an agent for preventing migration of the pyrethrin and piperonyl butoxide repellent into foods stored in contact with the textiles and for otherwise retaining the repellent in the textiles. Suitable agents were found to be ethylene glycol monoricinoleate, pentaerythritol monoricinoleate, water soluble polyalkylene glycol, polypropylene triol of average molecular weight 700, ricinoleyl ricinoleate, corn oil, tung oil, linseed oil, oleic acid, linoleic acid dimer, polypropylene pentol of average molecular weight 400, and linoleic acid trimer.
