Chemical compositions that present synergic effect for repellency of insects in personal hygiene products, cosmetics for human use, in animals and on inanimate surfaces in general

Abstract

Chemical compositions or mixture of components are described herein which, in combination and in diverse proportions with each other, present synergic effect, increasing the potential of insect repellent power, time of protective action and bestowing new insecticidal action, in personal hygiene products among others, as insect repellent among others. The synergic mixture is composed of 1-piperidinecarboxylic acid, 2(2-hydroxyethyl)-, 1-methylpropyl ester (Icaridin—CAS 119.515-38-7), N,N-dimethyl-3-methylbenzamide (DEET—Diethyltoluamide—CAS 134-62-3) combined with 3-Phenoxybenzyl 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate (Permethrin—CAS 52.645-53-1) and/or 5-[[2(2-butoxyetoxy)etoxy]methyl]-6-propyl-1,3-benzodioxole (Piperonyl Butoxide—CAS 51-03-6). These mixtures of chemical compounds in diverse proportions, considering two or more of these cited components, present capacity of repelling insects on skin human, in animals or any other inanimate surface, superior to the already known capacity of repellancy of Icaridin and DEET individually and, attributes new insecticidal characteristics to the insect repellent products.
