Definitions
- the present invention relates to a repellent composition against insects, in particular mosquitoes.
- the repellent compositions may come in various forms such as sprays, lotions, wipes and sticks for topical application to protect the skin from disease-carrying insects.
- repellent compositions can also be used in aerial diffusion using suitable devices allowing their evaporation or atomization.
- DEET /V,/V-diethyl-m-toluamide
- Other compounds used as insecticides include pyrethroids (permethrin and 5-permethrin). These synthetic compounds (amides, imides, piperidines, phthalates and permethrins) induce more or less significant toxic effects on the central nervous system. The immediate toxicity of the majority of these chemicals is generally low but their use can, in the long term, seriously harm public health, particularly in terms of fertility and cancer.
- Patent application BR 0 103 766 A describes a repellent composition which comprises vegetable oil of Carapa guianensis, essential oil of Eucalyptus citriodora and a solvent.
- insect repellent compositions particularly mosquito repellents, which comprise natural constituents, for example example of plant extracts, and which have the longest possible protection period, and at least several hours.
- the inventor of the present invention has discovered, quite surprisingly, a synergistic effect between the essential oil of Hyptis suaveolens, an oil (chosen from vegetable oils, synthetic oils, semi-synthetic oils, oils of animal origin, mineral oils, silicone oils and fluorinated oils) and a mixture comprising p-menthane-3,8-diol (hereinafter abbreviated as "PMD") and/or an essential oil chosen from lemon eucalyptus essential oil and Eucalyptus globulus essential oil, and a repellent agent chosen from beta-caryophyllene and eucalyptol, to obtain a new insect repellent composition having a significantly improved total protection time compared to that expected taking into account the constituents used in this repellent composition.
