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

摘要

Chemical compositions or mixture of components are described hereinwhich, in combination and in diverse proportions with each other, presentsynergic effect, increasing the potential of insect repellent power, timeof protective action and bestowing new insecticidal action, in personalhygiene products among others, as insect repellent among others. Thesynergic 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-Phenoxybenzyl3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate (Permethrin - CAS52.645-53-1) and/or5-[[2(2-butoxyetoxy)etoxy]methyl]-6-propyl-1,3-benzodioxole (PiperonylButoxide - CAS 51-03-6). These mixtures of chemical compounds in diverseproportions, considering two or more of these cited components, presentcapacity of repelling insects on skin human, in animals or any otherinanimate surface, superior to the already known capacity of repellancyof Icaridin and DEET individually and, attributes new insecticidalcharacteristics to the insect repellent products.
