Description

Title of the invention: Insect repellent composition

[0001] The present invention relates to a repellent composition against insects, in particular mosquitoes.

[0002] According to the WHO (2017), more than 17% of infectious diseases are vector-borne, causing more than one million deaths each year. Mosquitoes are the main vectors of these diseases, specifically mosquitoes of the genera Aedes, Anopheles, and Culex, which transmit malaria, dengue fever, chikungunya virus disease, Zika virus disease, Rift Valley fever, yellow fever, West Nile fever, filariasis, and various encephalitides to humans. The number of people at risk of contracting dengue fever is estimated at more than 3.9 billion in over 129 countries, making it the most widespread viral infection, while malaria causes approximately 219 million cases worldwide and results in more than 400,000 deaths each year, with most deaths occurring in children under the age of 5.

[0003] Although the majority of transmitted diseases occur in endemic tropical and subtropical regions, international travel, along with rapid urbanization and globalization, has increased their prevalence in new, previously unaffected territories. This is the case in Europe, which in recent years has seen the appearance of certain mosquitoes that transmit arboviruses, such as Aedes albopictus. This mosquito currently represents a major risk in France as it continues to spread to new departments. In addition to disease transmission, mosquitoes can be a nuisance and disrupt outdoor activities. Their bites can also lead to secondary infections, itching, irritation, allergic reactions, or pain.

[0004] Among all the means implemented to combat insect-borne diseases, particularly mosquito-borne diseases, protection through repellent effects is a preferred strategy. Indeed, repellency prevents insect bites, and thus the spread of the aforementioned diseases. Therefore, there is a constant need to improve repellent compositions against disease-carrying insects.

[0005] Repellent compositions can be in various forms such as sprays, lotions, wipes and sticks for topical application to protect the skin from disease-carrying insects.

[0006] It is also known to impregnate textile materials (e.g., clothing, bedding, mosquito nets, upholstery fabrics) with repellent compositions in order to to protect oneself against disease-carrying insects: - either by wearing treated clothing, - either by protecting one's environment with a mosquito net or treated bedding or furniture fabric.

[0007] Therefore, various treatments for textile materials have been developed to give them repellent properties against disease-carrying insects. These treatments consist of impregnating the textile material with a repellent composition which may, for example, be in the form of a spray containing repellent active ingredients.

[0008] In addition, repellent compositions can also be used in aerial diffusion through suitable devices allowing their evaporation or atomization.

[0009] With regard to active ingredients used as mosquito repellents, synthetic insecticides are used extensively. The most effective molecule for repelling mosquitoes is MAMicthyl-m-toluamid (hereinafter abbreviated as "DEET") applied topically or by space diffusion (spray). Other compounds used as insecticides include pyrethroids (permethrin and β-permethrin). These synthetic compounds (amides, imides, piperidines, phthalates, and permethrins) induce varying degrees of toxic effects on the central nervous system. The immediate toxicity of most of these chemicals is generally low, but their long-term use can seriously harm public health, particularly with regard to fertility and cancer.

[0010] While pyrethroids are less toxic to humans than DEET, which is not recommended for children under 12, mosquito resistance to these products has also been reported in 27 sub-Saharan countries. The intensive use of chemical insecticides has led to the development of resistance. Indeed, the major problem posed by mosquitoes is that they inexorably adapt to the insecticides on the market, primarily due to prolonged exposure times and the high doses used.

[0011] The development of this resistance to insecticides in different mosquito strains makes the emergence of less toxic alternative methods imperative. Research is being conducted in the field of natural repellents, which could provide interesting solutions for mosquito control. Pyrethroids, which are the most widely used insecticides today, were initially natural molecules derived from pyrethrum, itself extracted from chrysanthemum flowers; this was before chemists succeeded in producing the stabilized molecules that are used today.

[0012] The deleterious effects of synthetic products have revived the need to search for Alternatives for combating harmful mosquitoes and disease vectors. In this regard, plant extracts, particularly from tropical plants that have a long history as important components in traditional medicine and human nutrition, can be considered.

[0013] Thus, there is a real need to provide insect repellent compositions, particularly against mosquitoes, which include natural constituents, for example plant extracts, and which offer the longest possible protection time, and at least several hours.

[0014] The inventor of the present invention has discovered, in a completely surprising way, a synergistic effect between an oil and a mixture comprising p-menthane-3,8-diol (hereinafter abbreviated as "PMD") 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 exhibiting a total protection time significantly improved compared to that expected given the constituents used in this repellent composition.

[0015] The inventor has thus discovered that combining an oil with a mixture containing 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, makes it possible to obtain a repellent composition with a very long total protection time compared to repellent compositions known to date and currently on the market. The repellent composition according to the invention is therefore very effective in terms of protection against insects, and in particular against mosquitoes.

[0016] The invention primarily relates to an insect-repellent composition comprising at least: - PMD and / or at least one essential oil chosen from lemon eucalyptus essential oil and eucalyptus globulus essential oil, - at least one repellent agent chosen from beta-caryophyllene and eucalyptol, - a solvent, said repellent composition is characterized in that it further comprises at least one oil.

[0017] Beta-caryophyllene is one of the most abundant terpenes in nature. It is found in cloves, black pepper, cultivated hemp, basil, oregano, lavender, rosemary, caraway, and cinnamon. It is considered safe by the European Food Safety Authority as a food additive, flavor enhancer, cosmetic additive, and flavoring additive.

[0018] PMD is a monoterpene-type organic compound present in very small amounts quantities in the essential oil of the leaves of lemon eucalyptus (Corymbia ci-triodora or Eucalyptus citriodora).

[0019] The repellent composition according to the invention has the advantage of being able to comprise only natural constituents.

[0020] The oil can be chosen from vegetable oils, synthetic oils and semi-synthetic oils. By "semi-synthetic oil" is meant a vegetable oil that has been functionalized to obtain desired properties.

[0021] The oil can be chosen from mineral white oils, vegetable oils (from flowers, fruits, vegetables, trees, cereals, oilseeds, etc.), animal oils, synthetic oils, silicone oils and fluorinated oils.

[0037] Advantageously, the repellent composition further comprises Hyptis suaveolens essential oil. The Hyptis suaveolens plant is native to tropical America and is widespread in Africa, tropical Asia, and Australia. The main volatile compounds contained in the leaves of this plant are beta-caryophyllene, eucalyptol, sabinene, bergamotene, terpinolene, humulene, and limonene.

[0038] The inventor has indeed discovered, in a completely surprising way, a synergistic effect between the essential oil of Hyptis suaveolens, an oil (preferably an oil chosen from those described above) and a mixture comprising PMD and / or at least one essential oil chosen from the essential oil of lemon eucalyptus and the essential oil of Eucalyptus globulus and a repellent agent chosen from beta-caryophyllene and eucalyptol to obtain a new insect repellent composition with a protection time significantly improved compared to that expected given the constituents used in this composition.

[0039] The inventor has thus discovered that combining Hyptis suaveolens essential oil with an oil (preferably one chosen from those described above) and a mixture containing 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 makes it possible to obtain a repellent composition with a very long total protection time compared to repellent compositions known to date and currently on the market. The repellent composition according to this preferred embodiment of the invention is therefore very effective in terms of protection against insects, and in particular against mosquitoes.

[0059] “Qsp” is the acronym for “Quantity sufficient for” to signify that the the mass percentage of solvent in the repellent composition is such that, added to the percentages of all the other constituents of said repellent composition, a total of 100% is obtained.

[0060] Advantageously, the repellent composition according to the invention may further comprise between 0.5% and 10% of Hyptis suaveolens essential oil.

[0067] The present invention also relates to a method for manufacturing the repellent composition as described above. The manufacturing method comprises at least the following steps: 1) We prepare an active base by carrying out the following steps a) and b): a) the PMD and / or at least one essential oil chosen from lemon eucalyptus essential oil and Eucalyptus globulus essential oil, are mixed with at least one repellent agent chosen from beta-caryophyllene and eucalyptol and optionally Hyptis suaveolens essential oil, b) at least one oil is added to the mixture from step a), preferably an oil chosen from those described above, so as to obtain the active base, 2) The repulsive composition is finalized as follows: 2a) when the solvent is water: - Optional additional lipophilic constituents are added to the active base, - An aqueous phase is prepared by adding optional additional hydrophilic constituents to water. - the aqueous phase is mixed with the active base, to which optional additional lipophilic constituents have been added, in order to obtain the repellent composition in the form of an oil-in-water emulsion, 2b) when the solvent is alcohol: - the active base is mixed with alcohol and optional additives tionals so as to obtain the repellent composition in a sprayable form.

[0068] At the end of step b), the active base is in the form of oily microdroplets. More specifically, PMD and / or at least one essential oil chosen from lemon eucalyptus essential oil and eucalyptus globulus essential oil, at least one repellent agent chosen from beta-caryophyllene and eucalyptol and optionally Hyptis suaveolens essential oil constitute the core of these microdroplets which is surrounded by at least one oil.

[0069] It is perfectly within the capabilities of a person skilled in the art to know whether the optional additional constituents are lipophilic or hydrophilic and whether they should therefore be added to the active base, to water or to alcohol.

[0070] When the solvent is alcohol, the constituents of the active base mix easily with the alcohol. There is no phase separation problem.

[0071] Furthermore, in this embodiment of the invention, once sprayed on the skin, the repellent composition provides a film-forming effect on the skin which can also allow an efficiency gain of 13.3% by simple friction.

[0072] When the solvent is water, the repellent composition is in the form of an oil-in-water emulsion. The repellent composition comprises microparticles containing the active base that are dispersed in the continuous aqueous phase. These microparticles spread easily on the skin, and the constituents of the active base are released more slowly than when the repellent composition contains alcohol as a solvent.

[0073] Therefore, the total protection times are longer when the repellent composition includes water as a solvent and is therefore in the form of an oil-in-water emulsion than when the repellent composition includes alcohol as a solvent.

[0074] Preferably, steps a) and b) are carried out at a temperature between 25°C and 60°C. For example, the temperature is 45°C. A water bath can be used for this purpose.

[0075] Steps a) and b) are advantageously carried out with a dispersion and homogenization device, for example an Ultra-Turrax ® device.

[0076] During step a), the mixing speed can be between 1,500 rpm and 7,000 rpm. In one embodiment of the invention, it is 5,000 rpm.

[0077] During step b), the mixing speed can be between 1,500 rpm and 18,000 rpm. In one embodiment of the invention, it is 13,000 rpm.

[0078] The duration of step a) can be between 1 minute and 10 minutes. In one embodiment of the invention, it is 3 minutes.

[0079] The duration of step b) can be between 1 minute and 10 minutes. In one embodiment of the invention, it is 7 minutes.

[0080] When the solvent is water, the optional additional lipophilic constituents are added to the active base by subjecting the mixture to a mixing speed of between 1,500 rpm and 18,000 rpm for a duration of between 1 and 10 minutes and at a temperature of between 25°C and 60°C. In one embodiment of the invention, the mixing speed is 13,000 rpm, the duration of this step is 3 minutes, and the mixing temperature is 45°C (obtained using a water bath). This step is advantageously carried out with a dispersion and homogenization device, for example, an Ultra-Turrax® device.

[0081] The optional additional hydrophilic constituents are added to the water by subjecting the mixture to a mixing speed of between 1,500 rpm and 18,000 rpm for a duration of between 1 and 10 minutes and at a temperature of between 25°C and 60°C. In one embodiment of the invention, the mixing speed is 14,000 rpm, the duration of this step is 5 minutes, and the temperature of the mixture is 45°C (obtained using a water bath). This step is advantageously carried out with a dispersion and homogenization device, for example, an Ultra-Turrax® device.

[0082] Finally, the aqueous phase is mixed with the active base, to which optional lipophilic additional constituents may have been added, by subjecting the mixture to a mixing speed of between 1,500 rpm and 18,000 rpm for a duration of between 1 and 10 minutes and at a temperature of between 25°C and 60°C. In one embodiment of the invention, the speed is 13,000 rpm, the duration of this step is 3 minutes, and the temperature of the mixture is 45°C (obtained using a water bath). This step is advantageously carried out with a dispersion and homogenization device, for example, an Ultra-Turrax® device.

[0083] When the solvent is alcohol, the active base is mixed with alcohol by subjecting the mixture to a mixing speed of between 1,500 rpm and 10,000 rpm for a duration of between 1 and 10 minutes and at a temperature of between 20°C and 35°C. In one embodiment of the invention, the speed is 5,000 rpm, the duration of this step is 3 minutes, and the temperature of the mixture is ambient temperature (approximately 20°C). This step is advantageously carried out with a dispersion and homogenization device, for example, an Ultra-Turrax® device.

[0084] The repellent composition according to the invention can also be manufactured with an ultrasonic device (or other mechanically agitated devices). This device allows the components of the mixtures to be agitated at different stages of the manufacturing process.

[0085] The repellent composition according to the invention is preferably repellent against mosquitoes. For example, it may be against the following mosquito species: Aedes aegypti, Culex pipien and Anopheles gambiae.

[0086] The repellent composition can be applied directly to the skin.

[0087] In another embodiment of the invention, the repellent composition according to the invention can be diffused by air using a suitable device (for example, a device plugged into a power outlet).

[0088] The present invention also relates to a method of insect repellent treatment (preferably mosquito repellent) of a textile material which is characterized in that at least one part of said textile material is sprayed with at least one repellent composition according to the invention as described above.

[0089] The textile material can be chosen from natural textile materials such as cotton, feather, down, synthetic textile materials such as polyesters, nylon, acrylics or mixed textile materials.

[0090] In the context of the present invention, the term "textile material" means any textile material, chosen for example from textiles: - non-woven materials (e.g., felts), - woven (for example, warp and weft fabrics), or - knitted (for example, stitches), which consists of fibers, filaments or threads, taken alone or in mixtures thereof, which are of natural and / or synthetic origin.

[0091] The fibers can be spun, carded, or twisted. Natural fibers, filaments, or yarns can be of natural plant or animal origin and thus be chosen from cotton, wool, silk, jute, linen, hemp, and viscose. Synthetic fibers, filaments, or yarns can also be of synthetic origin and be chosen from polyamides, aramids, polyesters, polyacryl nitrites, aramids, polybenzimidazole, polyetheretherketone, polyphenylene sulfides, polyacrylics, chlorofibers, and polyolefins such as polypropylene or polyethylene.

[0092] The textile material treated with the repellent composition according to the invention can be used in various fields such as: - bedding (duvets, comforters, pillows, sheets, pillowcases, blankets); - clothing; - furniture (mosquito nets, rugs, curtains); - storage (packaging covers for clothes and bedding items such as duvets and blankets or furniture).

[0093] In an embodiment according to the invention, between 0.01 and 50 g / m2, preferably between 0.01 and 20 g / m2, of repellent composition according to the invention is sprayed onto said textile material.

[0094] Spraying can be carried out manually or automatically, for example with a mechanical, pneumatic, electric or compressed air sprayer.

[0095] The repellent compositions according to the invention may be ready-to-use or diluted in a suitable excipient before being sprayed onto the textile. It is within the capabilities of a person skilled in the art to determine any dilutions to be made before spraying the repellent composition according to the invention onto the textile.

[0096] The repellent treatment method according to the invention can consist of domestic use. For example, the user sprays the repellent composition on clothing, bedding or furniture, a storage cover or even a mosquito net to protect against insects (for example mosquitoes).

[0097] In another embodiment, the repellent treatment process according to the invention is implemented on an industrial line. The repellent composition according to the invention can thus be sprayed onto a textile material during an industrial process, for example an industrial process for manufacturing clothing, bedding or furniture, storage bags or even mosquito nets, so as to treat them before use.

[0098] The textile material can be chosen from clothing, bedding or furniture, storage covers or even mosquito nets.

[0099] The present invention thus relates to a textile material that has been treated by spraying with a repellent composition according to the invention as described above. The textile material may be a textile material as described above.

[0100] The present invention also relates to a product that has been treated by spraying with a repellent composition according to the invention as described above, preferably in the quantities described above. The product may be a product as described above, for example, a garment, a piece of bedding or furniture, a storage cover, or a mosquito net.

[0101] The invention will now be described by means of the following non-limiting examples.

[0102] Experimental part:

[0103] Experiments were carried out to measure the total protection time obtained with test compositions, namely repellent compositions according to the invention and comparative compositions, after their application to the skin and contact with mosquitoes.

[0104] During these experiments, mosquitoes of the species Anopheles gambiae and Aedes aegypti were used. The mosquito colony was maintained in a chamber subjected to a temperature of 27°C with a humidity level of 80% and a The photoperiod consisted of 12 hours of light and 12 hours of darkness. Mosquito larvae were fed fish food. Emerged adults were placed in 45 cm cube-shaped cages and fed a 10% sugar solution. The females used in the experiments were taken from batches of mosquitoes 4 to 7 days post-emergence.

[0105] The experimental protocol that was implemented is that described in the Guidelines for testing mosquito repellent efficacy on human skin (WHO / HTM / NTD / WHOPES / 2009.4), WHO, 2009.

[0106] This was the "arm in the cage test". Volunteers (men and women aged 20 to 45 years) to whom a composition to be tested had been applied to their forearms (i.e. on the surface extending from the wrist to the elbow, i.e. on average 600 cm2 of skin), successively placed their arms in the mosquito cage.

[0107] The total protection time corresponded to the time between the application of the tested composition to the skin and the first mosquito bite and / or the landing and remaining on the skin of 2 mosquitoes that probed without biting it.

[0108] A - Synergistic effect of the combination of beta-caryophyllene and lemon eucalyptus essential oil with coco-caprylate / caprate:

[0109] Example 1:

[0110] Table 1 below details the mass percentages of the constituents of a 1st repulsive composition according to the invention (“IQ-A1”). [YES] [Table 1] iQ-Al % mass ethyl alcohol 953 qsp lemon eucalyptus essential oil 20% Coco-capric triglyceride 10% vamlhene powder 10% beta-caryophyllene 0.50%

[0112] The total protection time of the first repellent composition according to the invention "IQ-A1" was 3 hours. This total protection time is very effective for a repellent composition.

[0113] Table 2 below details the mass percentages of the constituents of a first comparative composition (“C-Al”), namely a composition identical to composition IQ-A1 except that it was devoid of Coco-caprylate / caprate.

[0114] [Tables2] C-Al % mass ethyl alcohol 95° qsp lemon eucalyptus essential oil 20% Coco-caprylate / caprate 0.50 vanOHne powder 10% beta-caryophyllene 0.50.50

[0115] The total protection time of the first comparative composition “C-Al” was 1 hour.

[0116] Table 3 below details the mass percentages of the constituents of a 2nd comparative composition (“C-A2”), namely a composition identical to composition IQ-A1 except that it was devoid of beta-caryophyllene and lemon eucalyptus essential oil.

[0117] [Tables3] OA2% by mass, ethyl alcohol 95® Qsp, lemon eucalyptus essential oil 0%, cocorcaprylate / caprate: 10%, vanilla powder 10%, beta-caryophyllene 0%

[0118] The total protection time of the second comparative composition "C-A2" was zero minutes. In other words, with the second comparative composition, there was no protection against mosquitoes during this experiment.

[0119] The synergy between the active constituents, namely: - the mixture of lemon eucalyptus essential oil and beta-caryophyllene on the one hand, and - Coco-caprylate / caprate on the other hand, was calculated by comparing the total protection time results of composition IQ-A1 and comparative compositions C-Al and C-A2.

[0120] If the total protection time of the IQ-A1 composition was greater than that expected according to Colby's formula, there was synergy. If it was less, there was antagonism, and if it was equal, the mixture of lemon eucalyptus essential oil and beta-caryophyllene and coco-caprylate / caprate acted without interaction between them.

[0121] Colby's formula is:

[0122] [Math.l] E = X+Y-(X*¥) / iœ

[0123] X is the total protection time of the first comparative composition C-Al, namely 1 hour. Y is the total protection time of the second comparative composition C-A2, namely 0 minutes.

[0124] E is the expected total protection time of the mixture of lemon eucalyptus essential oil and beta-caryophyllene, as well as Coco-caprylate / caprate, without synergy between them, namely 1 hour.

[0125] The total protection time of the first repellent composition according to the invention IQ-A1 was 3 hours, therefore 3 times greater than the expected protection time of 1 hour.

[0126] This experiment clearly demonstrates the synergistic effect between the mixture of lemon eucalyptus essential oil and beta-caryophyllene with coco-caprylate / caprate. In other words, combining coco-caprylate / caprate with a mixture containing lemon eucalyptus essential oil and beta-caryophyllene significantly improves the total protection time (i.e., three times longer) of the repellent composition.

[0127] Example 2:

[0128] Table 4 below details the mass percentages of the constituents of a 2nd repulsive composition according to the invention (“IQ-A2”).

[0129] [Tables4] IQ-A2 % mass ethyl alcohol 95° qsp lemon eucalyptus essential oil 25% coco-caprylate / caprate 4% vanilla powder 10% beta-caryophyllene 5%

[0130] The total protection time of the second repellent composition according to the invention, "IQ-A2", was 3 hours. This total protection time is very effective for a repellent composition.

[0131] Table 5 below details the mass percentages of the constituents of a 3rd comparative composition (“C-A3”), namely a composition identical to composition IQ-A2 except that it was devoid of Coco-caprylate / caprate.

[0132] [Tables5] C-A3 wt% ethyl alcohol 95° qsp lemon eucalyptus essential oil 25% Coco-caprylate / caprate 0% vanishing powder 1% beta-caryophyllene 5%

[0133] The total protection time of the 3rd comparative composition “C-A3” was 1.6 hours.

[0134] Table 6 below details the mass percentages of the constituents of a 4th comparative composition (“C-A4”), namely a composition identical to composition IQ-A2 except that it was devoid of beta-caryophyllene and lemon eucalyptus essential oil.

[0135] [Tableauxô] C-A4 wt% ethyl alcohol 95® qsp lemon eucalyptus essential oil 0% Co-caprylate / caprate 4% vanilla powder 111 in e 10% beta-caryophyllene 0%

[0136] The total protection time of the 4th comparative composition "C-A4" was zero minutes. In other words, with the 4th comparative composition, there was no protection against mosquitoes during this experiment.

[0137] The synergy between the active constituents, namely: - the mixture of lemon eucalyptus essential oil and beta-caryophyllene on the one hand, and - Coco-caprylate / caprate on the other hand, was calculated by comparing the total protection time results of composition IQ-A2 and comparative compositions C-A3 and C-A4.

[0138] With the Colby formula detailed above, the expected total protection time of the mixture of lemon eucalyptus essential oil and beta-caryophyllene, as well as Coco-caprylate / caprate, without synergy between them, was 1.6 hours.

[0139] The total protection time of the 2nd repellent composition according to the invention IQ-A2 was 3 hours, therefore almost twice the expected protection time of 1.6 hours.

[0140] This experiment also demonstrates the synergistic effect between the mixture of lemon eucalyptus essential oil and beta-caryophyllene and Coco-caprylate / caprate. In other words, combining Coco-caprylate / caprate with a mixture containing lemon eucalyptus essential oil and beta-caryophyllene significantly improves the total protection time (i.e., almost twice as long) of the repellent composition.

[0141] B - Synergistic effect of the combination of beta-caryophyllene and lemon eucalyptus essential oil with Carapa procera oil:

[0142] Example 3:

[0143] Table 7 below details the mass percentages of the constituents of a 3rd repulsive composition according to the invention (“IQ-B1”).

[0144] [Tables?] IQ-B1 % mass ethyl alcohol 95° q.s.p. essential oil of lemon eucalyptus 20% Coropoprocera oil 10% vanillin powder 10% beta-caryophyllene 5%

[0145] The total protection time of the 3rd repellent composition according to the invention "IQ-B1" was 3.5 hours. This total protection time is very effective for a repellent composition.

[0146] Table 8 below details the mass percentages of the constituents of a 5th comparative composition (“C-Bl”), namely a composition identical to composition IQ-B1 except that it was devoid of Carapa procera oil.

[0147] [Tables8] C-Bl % mass ethyl alcohol 95° qsp lemon eucalyptus essential oil 20% Carapa procera oil 0% valerian powder 10% beta-caryophyllene 5%

[0148] The total protection time of the 5th comparative composition “C-Bl” was 1.5 hours.

[0149] Table 9 below details the mass percentages of the constituents of a 6th comparative composition (“C-B2”), namely a composition identical to composition IQ-A3 except that it was devoid of beta-caryophyllene and lemon eucalyptus essential oil.

[0150] [Tables9] C-B2 % mass ethyl alcohol 951, q.s. lemon eucalyptus essential oil 0% Carapa procera oil 10% vanillin powder 10% beta-caryophyllene 0%

[0151] The total protection time of the 6th comparative composition “C-B2” was 0.2 hours.

[0152] The synergy between the active constituents, namely: - the mixture of lemon eucalyptus essential oil and beta-caryophyllene on the one hand, and - Carapa procera oil, on the other hand, was calculated by comparing the total protection time results of composition IQ-B1 and comparative compositions C-Bl and C-B2.

[0153] With the Colby formula detailed above, the expected total protection time of the mixture of lemon eucalyptus essential oil and beta-caryophyllene, together with Coco-caprylate / caprate vegetable oil, without synergy between them, was 1.697 hours.

[0154] The total protection time of the 2nd repellent composition according to the invention IQ-B1 was 3.5 hours, therefore 2 times greater than the expected protection time of 1.697 hours.

[0155] This experiment also demonstrates the synergistic effect between the mixture of lemon eucalyptus essential oil and beta-caryophyllene and Carapa procera oil. In other words, combining Carapa procera oil with a mixture containing lemon eucalyptus essential oil and beta-caryophyllene significantly improves the total protection time (i.e., twice as long) of the repellent composition.

[0156] Example 4:

[0157] Table 10 below details the mass percentages of the constituents of a 4th repulsive composition according to the invention (“IQ-B2”).

[0158] [TableauxlO] IQ-B2 % by mass, water q.s. xanthan gum 1%, potassium cetyl phosphate 1%, glyceryl stearate citrate 1%, cetyl stearyl alcohol 4%, Carapa procera oil 15%, lemon eucalyptus essential oil 20%, tocopherol 1%, sorbic acid 3%, vanillin powder 5%, beta-caryophyllene 5%

[0159] The total protection time of the 4th repellent composition according to the invention, "IQ-B2", was 3.8 hours. This total protection time is very effective for a repellent composition.

[0160] Table 11 below details the mass percentages of the constituents of a 7th comparative composition (“C-B3”), namely a composition identical to composition IQ-B2 except that it was devoid of Campa procera oil.

[0161] [Tableauxll] C-B3 wt% SSU qsp xanthan gum 1% potassium cetyl phosphate 1% glyceryl stearate citrate 1% cetyl stearyl alcohol 4% Carapa procera oil 0% lemon eucalyptus essential oil 20% tocopherol 1% sorbic acid 3% vanillin powder 5% beta-caryophyllene 5%

[0162] The total protection time of the 7th comparative composition “C-B3” was 2 hours.

[0163] Table 12 below details the mass percentages of the constituents of an 8th comparative composition (“C-B4”), namely a composition identical to composition IQ-B2 except that it was devoid of beta-caryophyllene and lemon eucalyptus essential oil.

[0164] [Tables 12] C-B4 mass qs xanthan gum 1% potassium cetyl phosphate 1% glyceryl stearate citrate 1% cetyl stearyl alcohol 4% Carapa procera oil 15% lemon eucalyptus essential oil 0% tocopherol 1% sorbic acid 3% vanillin powder 5% beta-caryophyllene 0%

[0165] The total protection time of the 8th comparative composition “C-B4” was 0.5 hours.

[0166] The synergy between the active constituents, namely: - the mixture of lemon eucalyptus essential oil and beta-caryophyllene on the one hand, and - Carapa procera oil, on the other hand, was calculated by comparing the total protection time results of composition IQ-B2 and comparative compositions C-B3 and C-B4.

[0167] With the Colby formula detailed above, the expected total protection time of the mixture of lemon eucalyptus essential oil and beta-caryophyllene, together with Carapa procera oil, without synergy between them, was 2.49 hours.

[0168] The total protection time of the 4th repellent composition according to the invention IQ-B2 was 3.8 hours, therefore greater than the expected protection time of 2.49 hours.

[0169] This experiment also demonstrates the synergistic effect between the mixture of lemon eucalyptus essential oil and beta-caryophyllene and Carapa procera essential oil. In other words, the combination of Carapa procera oil with a mixture containing lemon eucalyptus essential oil and beta-ca- Ryophyllene helps to improve the total protection time of the repellent composition.

[0170] C - Synergistic effect of the combination of beta-carvophylene, lemon eucalyptus essential oil, Carapa procera oil and Hyptis suaveolens essential oil:

[0171] Example 5:

[0172] Table 13 below details the mass percentages of the constituents of a 5th repulsive composition according to the invention (“IQ-C1”).

[0173] [Tables 13] ;Q-C1 % mass qsp xanthan gum 1% hexyl decanol 3% hexyl decyl laurate 3% sucrose laurate 2% cetyl stearyl alcohol 1% Coropa procera oil 10¾ lemon eucalyptus essential oil 20% tocopherol 1% sorrel adsorbate 2% vanilla powder 5¾ Hyptes susveofens essential oil 2% beta-caryophyllene 5%

[0174] The total protection time of the 5th repellent composition according to the invention, "IQ-C1", was 10.5 hours. This total protection time of over 10 hours is very remarkable for a repellent composition. Such a total protection time has never been achieved with any known prior art repellent compositions.

[0175] Table 14 below details the mass percentages of the constituents of a 9th comparative composition (“C-Cl”), namely a composition identical to composition IQ-C1 except that it was devoid of Hyptis suaveolens essential oil.

[0177] The total protection time of the 9th comparative composition “C-Cl” was 3.8 hours.

[0178] Table 15 below details the mass percentages of the constituents of a 10th comparative composition (“C-C2”), namely a composition identical to composition IQ-C1 except that it was devoid of beta-caryophyllene, lemon eucalyptus essential oil and Campa procera oil.

[0180] The total protection time of the 10th comparative composition “C-C2” was 0 minutes.

[0181] The synergy between the active constituents, namely: - the mixture of lemon eucalyptus essential oil, beta-caryophyllene and Carapa procera oil on the one hand, and - Hyptis suaveolens essential oil, on the other hand, was calculated by comparing the total protection time results of composition IQ-C1 and comparative compositions C-Cl and C-C2.

[0182] With the Colby formula detailed above, the expected total protection time of the mixture of lemon eucalyptus essential oil, beta-caryophyllene and Carapa procera oil, together with Hyptis suaveolens essential oil, without synergy between them, was 3.8 hours.

[0183] The total protection time of the 5th repellent composition according to the invention IQ-C1 was 10.5 hours, therefore 2.8 times greater than the expected protection time of 3.8 hours.

[0184] This experiment also demonstrates the synergistic effect between the mixture of lemon eucalyptus essential oil and beta-caryophyllene, Carapa procera oil, and Hyptis suaveolens essential oil. In other words, the combination of Hyptis suaveolens essential oil with Carapa procera oil and a mixture containing lemon eucalyptus essential oil and beta-caryophyllene significantly improves the total protection time (i.e., 2.8 times better) of the repellent composition.

[0185] Example 6:

[0188] The total protection time of the 6th repellent composition according to the invention "IQ-C2" was 6 hours. This total protection time is truly very effective for a repellent composition.

[0189] Table 17 below details the mass percentages of the constituents of a 1st comparative composition (“C-C3”), namely a composition identical to composition IQ-C2 except that it was devoid of Hyptis suaveolens essential oil.

[0195] The synergy between the active constituents, namely: - the mixture of lemon eucalyptus essential oil, beta-caryophyllene and Carapa procera oil on the one hand, and - Hyptis suaveolens essential oil, on the other hand, was calculated by comparing the total protection time results of composition IQ-C2 and comparative compositions C-C3 and C-C4.

[0196] With the Colby formula detailed above, the expected total protection time of the mixture of lemon eucalyptus essential oil, beta-caryophyllene and Carapa procera oil, together with cV H y plis suaveolens essential oil, without synergy between them, was 3.5 hours.

[0197] The total protection time of the 6th repellent composition according to the invention IQ-C2 was 6 hours, therefore 1.7 times greater than the expected protection time of 3.5 hours.

[0198] This experiment also demonstrates the synergistic effect between the mixture of lemon eucalyptus essential oil and beta-caryophyllene, Carapa procera oil, and Hyptis suaveolens essential oil. In other words, combining Hyptis suaveolens essential oil with Carapa procera oil and a mixture containing lemon eucalyptus essential oil and beta-caryophyllene significantly improves the total protection time (i.e., 1.7 times better) of the repellent composition.

[0199] Example 7:

[0200] Table 19 below details the mass percentages of the constituents of a 7th repulsive composition according to the invention (“IQ-C3”).

[0201] [Tables l9] IQ-C3 % mass ethyl alcohol 95° oiled eucalyptus essential oil 20% Campe procera oil 10% vamlHri powder 5% beta-caryophyllene 5% Hyptef smvéafenes essential oil 3%

[0202] The total protection time of the 7th repellent composition according to the invention, "IQ-C3", was 8.5 hours. This total protection time of over 8 hours is truly very effective for a repellent composition.

[0203] The first comparative composition (“C-C3”) was a composition identical to composition IQ-C3 except that it was devoid of Hyptis suaveolens essential oil.

[0204] As explained above, the total protection time of the 1st comparative composition “C-C3” was 3.5 hours.

[0205] Table 20 below details the mass percentages of the constituents of a 13th comparative composition (“C-C5”), namely a composition identical to composition IQ-C3 except that it was devoid of beta-caryophyllene, lemon eucalyptus essential oil and Campa procera oil.

[0207] The total protection time of the 13th comparative composition “C-C5” was 0 minutes.

[0208] The synergy between the active constituents, namely: - the mixture of lemon eucalyptus essential oil, beta-caryophyllene and Carapa procera oil on the one hand, and - the essential oil A'Hyplis suaveolens on the other hand, was calculated by comparing the results of total protection time of the composition IQ-C3 and the comparative compositions C-C3 and C-C5.

[0209] With the Colby formula detailed above, the expected total protection time of the mixture of lemon eucalyptus essential oil, beta-caryophyllene and Carapa procera oil, together with Hyptis suaveolens essential oil, without synergy between them, was 3.5 hours.

[0210] The total protection time of the 6th repellent composition according to the invention IQ-C2 was 8.5 hours, therefore 2.4 times greater than the expected protection time of 3.5 hours.

[0211] This experiment also demonstrates the synergistic effect between the mixture of lemon eucalyptus essential oil and beta-caryophyllene, Carapa procera oil, and Hyptis suaveolens essential oil. In other words, combining Hyptis suaveolens essential oil with Carapa procera oil and a mixture containing lemon eucalyptus essential oil and beta-caryophyllene significantly improves the total protection time (i.e., 2.4 times better) of the repellent composition.
