Definitions

• the present invention relates to an insect repellant composition for application to human skin as well as hair, or clothing, as well as the fur of animals.
• the object of the invention is to provide an insect repellent composition which makes it possible to remedy the main drawbacks presented by known repellent compositions; namely: unpleasant odor and limited duration of effectiveness either by absorption or m abolishing Li on of the composition by the skin, or by perspiration due to high heat or stress or by abrasion of the composition caused in particular by washing the treated surface or by the movement of air on this surface. This is how we observe efficiency reductions of around 60%, compared to a wind-free atmosphere, when the wind reaches a speed of 190m / minute.
• the composition according to the invention comprises at least one active repellant, chosen from extracts of pelargonium, geranium, lavender, pyrethrum, lemon flower, as well as N, N-dié hy1-m-toluamide, a plasticizing agent and an agent amplifying the repellent effect of the above active compounds.
• the plasticizing agent is a vinyl compound.
• the vinyl compound is polyvinylpyrrolidone.
• the amplifying agent is cyclopentane-1-one-2-npentane-3-methyl ethyl ester known under the name of Hedione.
• the composition comprises, by weight, from 30 to 75% of 95% ethanol, from 5 to 50% of N, N-diethyl-m-toluamide, from 0, there 2% of polyvinylpyrrolidone, from 2 to 10% of isopropyl myristate, from 2 to 10% of dipropylene glycol, from 0.1 to 2.5% of amplifier, from 0.1 to 2.5% of a solubilizing homogenizing agent and natural extracts from 0.1 to 2.5%.
• the composition according to the invention which is repellent for most insects and in particular for the following mosquitoes: ⁇ edes Aegypti, Culex, Mansonia, Anopheles, Psorophora, for fleas, ticks, horseflies, black flies, black flies stable, Cerotopogonidae, has the main characteristic of allowing the creation, on covered surfaces and mainly on the skin where the repellant compositions lose their effectiveness as quickly as possible due to absorption, metabolization, perspiration and / or l 'abrasion, a film, which resists time, external conditions as well as changes in the state of the covered surface and which regulates and slows its release from the active ingredients of the composition, in which most of these ingredients remain present active repellents, ingredients whose activity is advantageously increased by the incorporation into the composition of an enhancer, said composition also having the advantage of being made up mainly of natural products which are non-toxic for humans and animals .
• This composition whose odor is pleasant and which contains, according to the invention and as described below, a plasticizing and fixing agent as well as an amplifying agent, has real repulsive activity for a minimum period of 4 to 8 hours which could reach 14 hours depending on external conditions when it is applied in the following quantities, which vary in particular according to outdoor atmospheric conditions, such as the temperature whose rise causes dispersion or abrasion from 0.05 to 0, 2 mg per cm on the skin and
• Said composition which contains polyvinylpyrrolidone, which constitutes the plasticizing and fixing agent for the formation of the abovementioned film, natural active repellent extracts, such as pelargonium, geranium, lavender, pyrethrum, lemon flowers, as well as NN-die hy1-m-toluamide, an amplifier consisting of cyclopentane -l-one-2- npentane-3-methyl ethyl ester whose property is to ensure a synergistic effect with the active repellent extracts, advantageously comprises, by weight, from 30 to 75% of 95% ethanol, from 5 to 50% of N, N-5 diethyl-m-toluamide, from 0.4 to 2% of polyvinylpyrrolidone, from 2 to 10% of isopropyl myristate, from 2 to 10% of dipropylene glycol, from 0.1 to 2.5% of the aforementioned enhancer and from 0.1 to 2.5% of a solubilizing homogenizing
• composition 10 polyoxyethylene nonyl phenyl ether known as "Lamacite" and from 0.1 to 2.5% of natural repellents.
• the aforementioned composition may also comprise a dye improving its appearance, this dye, introduced into the composition at a rate of
• composition comprising, by weight, 65.5% 95% ethanol, 20% N, N-diethyl-m-toluamide, 1% polyvinylpyrrolidone, 8% isopropyl myristate, 4% dipropylene glycol, 0.1% amplifying agent, 0.5% solubilizing homogenizing agent and 0.9%
• the repellant composition can be either in the form of an aerosol, or in the form of a gel which can in particular be used in a dispenser with a dispensing head.
• either propellant is used as durosol, at a rate of 20 to 25% by weight, ie a mixture of propane and butane at a rate of 40% by weight.
• the composition When the composition is in the form of a gel, it comprises by weight, 45 to 55% of the composition defined above, 25 to 35% of demineralized water, 12.7 to 17.5% of alcohol 95% ethyl, from 0.1 to 1.3% of a viscosity-increasing agent, such as a very high molecular weight polymer known as a "carbomer”, from 1.5% to 4.5% of hydrogenated cod liver oil, known in particular under the name of "Cremophor 2H40" and from 0.5 to 2% of polyoxyethylene (15) cocoamine known under the name of "Ethomeen C / 25".
• a viscosity-increasing agent such as a very high molecular weight polymer known as a "carbomer”
• hydrogenated cod liver oil known in particular under the name of "Cremophor 2H40”
