Description

METHOD FOR FIXING ACTIVE MOLECULES ON A SUPPORT, ACTIVE ELEMENT OBTAINED THEREBY AND CHEMICAL COMPOSITION FOR CARRYING OUT SAID METHOD

The present invention relates to a method for fixing, on a support, active molecules exhibiting an activity, in particular physical, physicochemical, chemical, biochemical or biological activity, either against unwanted organisms or phenomena, or in favor of of a desired phenomenon. This invention also relates to an active element comprising a support as well as to such active molecules, fixed on this support. Finally, the invention relates to a chemical composition for the implementation of this process and / or for producing this active support. The invention relates to the field of media processing and will find an application when it comes to producing an active element comprising a support provided with active molecules fixed on this support, so that this active element has specific properties, more particularly against an undesirable effect or, conversely, in favor of a desired effect.

Processes are already known from which the implementation makes it possible to fix such active molecules on such a support. Thus, by the document EP-0,104,608 there is known a first method of ensuring the attachment of active molecules on a support by making a covalent bond between this support and these molecules. To achieve such a covalent bond and allow attachment and orientation of the active molecules on this support, it is necessary to substantially modify the support which is provided by means of a plasma which has the disadvantage of on the one hand, to require a substantial supply of energy and, on the other hand, to cause the degeneration of the active molecules and / or the support which thus lose their initial chemical nature and, by therefore, the activity for which these molecules were chosen.

It is also known from EP-I.598.475 a method consisting, first of all, in incorporating active molecules into a bath composed of an acrylic binder and a silicone elastomer, this for the realization of a chemical composition then serving to treat the support which, finally, is dried at a minimum temperature of HO ⁰ C. This process has the effect of causing the imprisonment of the active molecules in the acrylic binder resulting in a substantial loss, or total activity of these molecules.

WO2004065024 discloses a method of treating a support with a chemical composition containing, on the one hand, a binder consisting of polymerizable and / or crosslinkable chemical compounds and, on the other hand, a chemical compound having a strong ionic character. This treatment is intended to provide an ionic charge to the support by fixing the ionic chemical compound on the support by polymerization and / or crosslinking of the binder at high temperature. In this regard, it will be observed that such a fixation entails, in fact, on the one hand, a stiffening of the support and, on the other hand, a flooding of the ionic chemical compounds within the binder so that the number of ionic charges for binding of the active molecules is considerably reduced, or even non-existent. Finally, US-5,631,072 relates to a method of attaching an insecticide to a fabric. Such a process consists, first of all, in making a paste containing an insecticide dispersion, a thickening agent, a polymer and a crosslinking agent. This method then consists in coating a support with this paste before polymerization of the polymer and crosslinking of the crosslinking agent. This polymerization and crosslinking has the effect of trapping the insecticide molecules in the crystalline mass of the polymer so that these molecules lose their effectiveness considerably.

It will be observed, again, that the processes described above: - are particularly selective and able to handle only certain types of media;

- allow only a low remanence of the functionalization treatment; - do not systematically allow active molecules to remain available and effective;

- modify the feel and texture of the medium;

- Do not allow to fix all the active molecules deposited on the support. The present invention is intended to overcome the disadvantages of the methods of the state of the art.

To this end, the invention relates to a method for fixing, on a support, active molecules having an activity, in particular physical, physicochemical, chemical, biochemical or biological activity, either against organisms or undesirable phenomena, or in favor of a desired phenomenon, this method being characterized in that:

a chemical composition is produced containing at least cationic micelles each comprising at least one active molecule;

the support is impregnated with the chemical composition of cationic micelles;

the active molecules are fixed on the support by producing at least one electrostatic type bond between the cationic micelles and this support.

The invention also relates to an active element comprising, on the one hand, a support and, on the other hand, active molecules, fixed on this support, and having an activity, in particular physical, physicochemical, chemical, biochemical or biological, either against organisms or undesirable phenomena, or in favor of a desired phenomenon, characterized in that the active element comprises cationic micelles, on the one hand, fixed on the support by on least one electrostatic type bond and, on the other hand, each having at least one active molecule. This invention further relates to a chemical composition for carrying out the above-mentioned method and / or for producing the above-mentioned active element. This chemical composition is characterized in that it contains at least cationic micelles each comprising at least one active molecule having an activity, in particular a physical, physicochemical, chemical, biochemical or biological activity, or against organisms or undesirable phenomena, either in favor of a desired phenomenon. The advantages of the present invention consist in that the fixing of the active molecules on the support is ensured by performing at least one electrostatic type bond between this support and cationic micelles each comprising at least one such active molecule. Such a type of bond makes it possible to optimize the quantity of molecules fixed on a support, to guarantee a high level of fixation as well as a significant remanence over time. Such a connection allows, again, good weather resistance (this for externally implanted supports) as well as washes (this for washable media, especially textiles).

Another advantage is that the process according to the present invention makes it possible to treat any type of support, in particular polar, apolar or anionic.

The nature and the material of such a support are in no way limiting and, according to a substantial advantage of the invention, it can be envisaged to fix active molecules on any support, made of any material, such as wood, concrete, textile, metal, leather, ceramics, stone, paper, cardboard or other. Moreover, this process does not in any way denature the active molecules, which advantageously makes it possible to preserve the chemical nature and the active properties of these molecules and to confer them on the support and, thus, on the active element without alteration. Other objects and advantages of the present invention will become apparent from the following description. relating to embodiments which are given only as indicative and non-limiting examples.

The understanding of this description will be facilitated with reference to the appended drawings in which: FIG. 1 is a schematic representation of the electrostatic fixation, on a polar support, of a micelle containing an active molecule;

FIG. 2 is a schematic representation of the electrostatic fixation, on an anionic support, of a micelle containing an active molecule;

FIG. 3 is a schematic representation of the electrostatic attachment, on an apolar support, of a micelle containing an active molecule;

FIG. 4 is a diagrammatic representation of an electrostatic fixation and by polymerization and / or crosslinking, on a support, of micelles containing an active molecule.

The present invention relates to the field of the treatment of supports 2 and will find an application when it comes to producing an active element 1 comprising a support 2 provided with active molecules 30, on the one hand, fixed on this support 2 and, d on the other hand, presenting an activity, in particular physical, physicochemical, chemical, biochemical or biological activity,

Against unwanted organisms or phenomena, or in favor of a desired phenomenon.

This invention relates, more particularly, to a process for fixing such active molecules on such a support 2.

Such a process consists in: - producing a chemical composition containing at least cationic micelles 3 each comprising at least one active molecule 30;

the support 2 is impregnated with this chemical composition of cationic micelles 3; the active molecules 30 are immobilized on the support 2 by producing at least one type of binding electrostatic between the cationic micelles 3 and this support 2.

In this regard, it will be observed that the realization of such a chemical composition can be ensured in various ways, this essentially according to the type of the active molecules which should be arranged in the form of micelles 3.

Thus, when the active molecules are of the polarized type, the method comprises making a chemical composition of cationic micelles 3 each having a plurality of polarized active molecules. For producing such a composition, a micellar solution containing micelles 3, each consisting of an assembly of a plurality of polarized active molecules, is produced first and from polarized active molecules. The method then consists in adding to this micellar solution chemical compounds intended to cationize these micelles 3.

When the active molecules are of the cationic type (more particularly when these molecules have a high cationic polarity), the process consists in producing a chemical composition of cationic micelles 3, each comprising at least one such cationic active molecule. . The production of such a composition is ensured by producing a micellar solution containing, on the one hand, cationic active molecules and, on the other hand, chemical compounds 31 intended to form cationic micelles with these cationic active molecules. .

When the active molecules are of neutral or cationic type (more particularly when these molecules have a low cationic polarity), the process consists in producing a chemical composition of cationic micelles 3 each comprising at least one active molecule. neutral or cationic, this by realizing, firstly and from such active molecules 30 and chemical compounds 31 intended to form micelles 3 with such active molecules 30, a micellar solution containing micelles 3 each constituted by an assembly of at least one such active molecule 30 and at least one such chemical compound 31.

The method then consists in adding to this micellar solution chemical compounds intended to cationize these micelles 3.

Active molecules of the anionic type are still known.

For such anionic active molecules, a chemical composition of cationic micelles 3, each comprising at least one such anionic active molecule, is carried out, this:

neutralizing these anionic active molecules;

by carrying out, from these anionic active molecules and chemical compounds 31 intended to form micelles 3 with such anionic active molecules, a micellar solution containing micelles 3, each constituted by an assembly of at least one such anionic active molecule and at least one such chemical compound 31;

by then adding, to this micellar solution, chemical compounds intended to cationise these micelles 3.

In this connection, it should be noted that, according to a particular embodiment of the invention, the anionic active molecules are neutralized by means of specific chemical compounds incorporated in the chemical composition (more particularly in the micellar solution). .

However, according to a preferred and advantageous embodiment of the invention, the anionic active molecules are neutralized by chemical compounds 31 intended to form micelles with such anionic active molecules, these chemical compounds being chosen from cationic ensure such neutralization.

As mentioned above, the process according to the invention consists, when a chemical composition is made, of producing, first of all, a micellar solution. Also and according to an additional feature of the invention, when such a micellar solution is produced, in fact, a solution containing, on the one hand, a solvent of the organic type (oil, alcohol, ketone or the like) and / or mineral (water or the like) and, on the other hand, active molecules solubilized in this solvent. According to another embodiment, such active molecules can also be in an emulsifiable or dispersible form in such a solvent.

In this connection, it will be observed that such an emulsion or such a dispersion can then be produced either chemically (more particularly by means of emulgators or dispersants) or mechanically (more particularly by using a compression method).

When such active molecules 30, naturally, form little or no micelles 3, the process according to the invention consists, then and where appropriate, in introducing into this solution chemical compounds 31 intended to form micelles 3 with such active molecules 30.

Another characteristic of the process according to the invention is that, if appropriate, at least one acidic substance or at least one acid, especially a mixture, is added to the cationic micellar composition (more particularly to the micellar solution). of acids.

In this respect, it will be observed that such an addition advantageously makes it possible to neutralize the pH of the chemical composition (more particularly that of the micellar solution) as well as that of the support 2 to be treated. In addition, such an addition makes it possible to neutralize the alkalis present in this composition (more particularly in the micellar solution) and on this support 2 which, in the absence of such an addition, are capable of reacting with the chemical compounds intended to to cationize these micelles.

As mentioned above, the process consists in the fact that the support 2 is impregnated with the chemical composition of cationic micelles 3. Such impregnation is ensured by immersion (more particularly inside a tank, a bacholle, a washing machine or the like), by spraying (more particularly by means of at least one spray nozzle) or by coating (more particularly by means of a doctor blade, a brush, a roller or similar) . An additional feature of this process is that after impregnation of the support 2 with the cationic micellar composition, the drying of the impregnated support 2 is ensured.

In this connection it will be observed that such a drying of the support 2 consists, more particularly, in ensuring the drying of the cationic micellar composition which impregnates this support 2.

In fact, such drying is more particularly suitable after impregnation of this support 2 by immersion. In such a case, such drying is preferably provided after a spin of the impregnated support 2.

As regards the drying, this is ensured at a temperature of between 20 and 200 ^° C., preferably between 20 and 180 ^° C., in particular between 20 and 150 ^° C.

Preferably, this drying is ensured inside an oven, preferably before cooling of the active element 1, either by passing it through a cooling zone of the air-flow type, or by direct cooling of the on cooling cylinders or the like. As mentioned above, the active molecules 30 are immobilized on the support 2 by producing at least one electrostatic-type bond between the cationic micelles 3 and this support 2.

In this regard, it should be noted that the realization of such a fixation can be provided in different ways, this essentially according to the nature of the support 2.

Also, when this support is of the polar type as illustrated in FIG. 1, this support 2 has, in fact (and more particularly at its surface), permanent dipoles which make it possible to create, between the dipoles of this support 2 and the cationic micelles 3 to be fixed on this support 2, strong electrostatic bonds of the "ion-dipole" type.

By way of examples, there are known polar-type supports 2 consisting of: cellulosic supports such as paper, wood, flax, viscose, hemp, ramie, jute, or rayon;

an ester (for example a polyester), an amide (for example a polyamide), a polyvinyl chloride (PVC); - a concrete, a cement mortar or other.

Also known are supports 2 having, naturally, a strong ionic polarity of anionic type as shown in FIG.

In such a case, the fixing of the cationic micelles 3 on such a support 2 is ensured by producing, between this support 2 and the cationic micelles 3 to be fixed on the support 2, a strong electrostatic bond of the ionic type, more particularly of the type " ion-ion ".

It is also known supports 2 apolar type as shown in Figure 3, more particularly constituted by supports 2 having apolar groups.

Surprisingly, the process according to the present invention also makes it possible to fix cationic micelles on supports 2 of this type. In this regard, it will be observed that such cationic micelles 3, in the vicinity of such a non-charged apolar support 2, cause a deformation of the electron cloud of this support 2 (polarizing field caused by the highly cationic charge of the micelle 3) and the creation of an induced dipole. In this case, the fixing of such a cationic micelle (comprising at least one active molecule 30) is ensured by providing, between this support 2 and the cationic micelles 3 to be fixed on the support 2, a strong electrostatic bond of the " induced ion-dipole ". As an example of nonpolar support 2, there may be mentioned supports 2 of polyolefin type, more particularly polyethylene, polypropylene or the like.

Thus, the fixing of a cationic micelle 3 is carried out on a support 2 of polar, apolar or anionic type, except however a support 2 of cationic type. Such fixing is ensured by performing an electrostatic bonding, in a particularly advantageous manner, on the one hand, to fix effectively and perennially almost all the active molecules 30 on such a support 2 and, on the other hand, to retain the properties (physical, chemical, biological) of the active molecules without altering them.

As mentioned above, certain active molecules require, in order to form micelles 3, the presence of specific chemical compounds 31 intended to form such micelles 3 with these active molecules 30.

As will be discussed in more detail below, such chemical compounds 31 may be composed of polymerizable and / or crosslinkable compounds.

In such a case, the electrostatic fixation of the cationic micelles (more particularly the active molecules 30) on the support 2 can be completed by carrying out a fixation by polymerization and / or crosslinking of the chemical compounds 31 intended to form cationic micelles with these active molecules 30 as illustrated in FIG.

The implementation of the method described above leads to the production of an active element 1 comprising, on the one hand, a support 2 and, on the other hand, active molecules (30, more particularly arranged within at least one cationic micelle 3) fixed on this support 2.

In fact and according to the invention, the active element 1 comprises cationic micelles 3, on the one hand, fixed on the support 2 by at least one electrostatic type connection and, on the other hand, each comprising at least one an active molecule 30. As discussed above, the active molecules may be of the polarized type. In such a case, the cationic micelles 3 each comprise at least a plurality of polarized active molecules. In this regard, it will be observed that, in this case and according to a preferred embodiment of the invention, each cationic micelle 3 comprises a plurality of polarized active molecules 30 which can be in the form of a micelle 3, naturally and in the absence of any additional chemical compound capable of forming such a micelle 3 with such an active molecule 30.

The active molecules can also be neutral or cationic.

In such a case, the cationic micelles 3 each comprise, on the one hand, at least one such neutral or cationic active molecule and, on the other hand, at least one chemical compound 31, of nonionic or cationic type, forming a cationic micelle 3 with at least one such active molecule 30.

Finally, these active molecules can, again, be of the anionic type.

The cationic micelles 3 each then comprise, on the one hand, at least one anionic active molecule 30 and, on the other hand, at least one chemical compound 31, preferably of cationic type, forming a cationic micelle 3 with at least one such anionic active molecule 30 and, if appropriate (more particularly when the chemical compound 31 forming a micelle 3 with the active molecule 30 is not of cationic type or is not capable of electrically neutralizing such a molecule), at least a chemical compound for electrically neutralizing such anionic active molecule.

As mentioned above, a cationic micelle 3 may comprise at least one chemical compound 31 forming such a micelle 3 with at least one active molecule 30 (anionic, neutral or cationic). In this regard, it will be observed that, according to a first embodiment, such a chemical compound 31 may consist of a surfactant.

However, according to another embodiment, such a chemical compound 31 may consist of a polymerizable and / or crosslinkable type compound.

As mentioned above, the active element 1 in accordance with the invention comprises a support 2 as well as active molecules 30 fixed to this support 2. Such a support 2 may, then and as described above, be polar type (FIG. 1), apolar (FIG. 3) or anionic (FIG. 2), whereas the electrostatic bond between a cationic micelle 3 and this support 2 is of the ion-dipole, ion-dipole-induced or ionic type, respectively ( ion-ion). The invention has a particularly versatile character so that the implementation of the aforementioned method makes it possible to obtain a plurality of singularly different active elements 1 comprising different active molecules having an activity, in particular physical, physicochemical, chemical, biochemical or biologically, either against unwanted organisms or phenomena, or in favor of a desired phenomenon.

Thus, and according to a first embodiment, the active molecules may have an activity in the prophylactic or curative treatment of a disease.

In such a case, such active molecules 30 may be associated with a support 2 constituted by a protective element (more particularly a dressing) or by a clothing element (more particularly a garment, in particular called "intelligent").

According to a second embodiment, the active molecules may exhibit activity against pathogenic elements and / or microorganisms, in particular viruses, bacteria, microbes or the like. In this respect, it will be observed that such an activity can be of the biocidal type. Active molecules having such a The activity may then consist of isothiazolinone derivatives, silver salts, triclosan, titanium dioxide or the like.

A third embodiment consists in the fact that the active molecules have an activity in favor of a visual phenomenon associated with this support 2. Such a visual phenomenon can be a photoluminescence, a fluorescence or a coloration of this support 2.

According to a fourth embodiment, the active molecules having an activity against parasites (especially animals) or animals, more particularly mites or insects.

Such activity may be repulsive, annoying or lethal. More particularly, such active molecules may be of the pesticide, insecticide, insect repellent or the like type.

By way of example, it is possible to use pesticide-type active molecules such as permethrin, deltamethrin, fenitrothion, cyfluthrin, geraniol,

DEET, DDT, imidazole and triazole, linuron or diuron, malathion or the like.

A fifth embodiment consists in that the active molecules have an activity against the fixation of staining products on said support 2.

According to a sixth embodiment, the active molecules have an activity against radiation, especially ultraviolet radiation. Such molecules may, more particularly, be titanium dioxide. A seventh embodiment is that the active molecules can exhibit an activity against fungi (these active molecules then being of the fungicidal type) or plants, especially weeds (these active molecules then being of the herbicide type). ), mosses, plant pests (these active molecules then being of the pesticide type) or the like. Finally, the active molecules can have an activity against olfactory nuisances, more particularly those caused by substances produced by the human or animal body (sweat, urine, excrement), by waste (garbage, wastewater) or by organic or plant residues.

Such active molecules can be used to treat all foci that generate such odor nuisances and preferably exhibit activity as part of the odor neutralization treatment.

By way of example, it is possible to employ active molecules chosen from the following compounds: aliphatic alcohols (such as decanol, citronelol, geraniol), aldehydes (such as normal or branched dodecanal), phenols (such as eugenol and isoeugenol).

In fact, these active molecules can be attached to at least one type of support 2 determined.

In this regard, it will be observed that such a support 2 may then be constituted, at least in part, by: - an item of clothing (garment, especially trellis);

- a dressing element;

- a decorative element (curtain, drapery, curtain, stretch ceiling);

- shelter element (tent); - a protective element (dressing, tarpaulin, blind, mosquito net).

A particular embodiment is that the support 2 can be made, at least in part, of a textile material (natural or synthetic). Such a material may be of the knitted, woven, nonwoven or other type and be constituted by fibers and / or natural, artificial or synthetic filaments, such as, for example, polyester, viscose, cotton, wool, polyamide, aramid, silk, polypropylene, polyethylene or a mixture of different fibers and / or filaments. In fact, the elements described above can then receive active molecules as described above and having an activity, either in favor of a visual phenomenon, or against: pathogenic elements and / or microorganisms;

- parasites or animals;

the fixing of staining products on said support;

- radiation;

- mushrooms or vegetables; - olfactory nuisance (sweat).

Another type of embodiment may consist in that the support 2 is constituted by:

- a constituent element (wall, ceiling, floor, balcony, terrace, roof, frame, beam, closing device, door, window);

- a covering element (stretch ceiling);

- an element of decoration (painting, coating, curtain, wall hanging, slab, paving stone, tile);

- a storage element (bin, bucket); - an item of equipment (sanitary, including urinal);

- A protection element (shutter, shutter, blind, mosquito net) that includes a building, including a residential building, storage, livestock, public utility (including public toilets). Such an element can then be made of any material such as wood, concrete, textile, metal, leather, ceramic, stone, paper, cardboard, plastic or other.

Again, such an element can receive active molecules as described above and having an activity, either in favor of a visual phenomenon, or against pathogenic elements and / or microorganisms, parasites or of animals, the fixation of staining products on said support, radiation, fungi or plants, olfactory nuisance. Finally, a type of embodiment consists, again, in that the support 2 is constituted by an element of an installation for storing, conveying and / or treating waste.

In this connection, it will be observed that such an element can then be constituted by an element of a conveyor system (skips, pipes, sewers) and / or treatment (wastewater treatment plants) of waste, more particularly wastewater.

As mentioned above, the invention relates, on the one hand, to a method for binding active molecules to a support 2 and, on the other hand, to an active element 1 comprising such a support 1 and to such molecules 30.

The invention also relates to a chemical composition for the implementation of this process and / or for the production of this active element 1. As mentioned above, this chemical composition contains at least cationic micelles comprising each having at least one active molecule having an activity, in particular physical, physicochemical, chemical, biochemical or biological activity, either against unwanted organisms or phenomena or in favor of a desired phenomenon.

According to a first embodiment, such a chemical composition contains micelles 3 each comprising at least one active molecule 30 of polarized type and each consisting, and preferably, of an assembly of a plurality of these polarized active molecules.

In such a case, this chemical composition also comprises at least one chemical compound intended to cationize such a micelle 3.

A second embodiment is that the chemical composition contains cationic micelles each having at least one cationic active molecule, more particularly a cationic active molecule having a strong cationic polarity.

This cationic micelle 3 then also comprises at least one chemical compound 31 forming a cationic micelle with at least one such cationic active molecule. According to a third embodiment, the chemical composition contains micelles 3 each comprising, on the one hand, at least one neutral or cationic active molecule (more particularly one molecule having a low cationic polarity) and, on the other hand, at least one chemical compound 31 forming a micelle 3 with at least one such neutral or cationic active molecule.

Such a chemical composition also contains at least one chemical compound for cationizing such a micelle 3.

A fourth embodiment relates to a chemical composition containing, on the one hand, micelles 3 comprising at least one anionic active molecule, at least one chemical compound 31 (preferably of the cationic type) forming a micelle 3 with at least one such anionic active molecule and, where appropriate (more particularly when the chemical compound forming a micelle 3 with the active molecule 30 is not of cationic type or is not capable of electrically neutralizing such an anionic active molecule), less a chemical compound (preferably cationic type) for electrically neutralizing such an anionic active molecule.

In this regard, it should be observed that the chemical compound for electrically neutralizing an anionic active molecule is constituted by a chemical compound (preferably of cationic type, especially a cationic polymer) distinct from that forming a micelle 3 with at least such an anionic active molecule.

However, according to a preferred embodiment, the chemical compound for electrically neutralizing such an anionic active molecule is constituted by the chemical compound 31 (preferably cationic) forming a micelle 3 with at least one such anionic active molecule (such as compound being, more particularly, constituted by a cationic polymer). Finally and in accordance with this fourth embodiment, the chemical composition also contains at least one chemical compound intended to cationize such a micelle 3. As mentioned above, this chemical composition may, depending on the type of active molecule 30 considered, contain at least one chemical compound 31 forming a micelle 3 with at least one active molecule 30.

In this regard, it will be observed that such a chemical compound 31 may consist of a polymerizable and / or crosslinkable compound, in particular of nonionic or cationic type.

By way of example of a polymerizable and / or crosslinkable nonionic compound, it is possible to use a binder of the styrene butadiene, polyurethane, acrylic, urethane, vinyl acetate or the like type, or even a mixture based on one of at least of these compounds.

The concentration of such a polymerizable and / or crosslinkable nonionic compound preferably varies between 0.1% and 30% (which corresponds to a quantity of compound of between Ig and 300g per liter of composition).

However, and according to another embodiment, such a chemical compound 31 forming a micelle may, again, be constituted by a surfactant, in particular of nonionic or cationic type. As mentioned above, the chemical composition may, depending on the type of active molecule 30 considered, contain at least one chemical compound for cationizing a micelle 3.

Such a chemical compound is constituted by a chemical compound having a strong cationic polarity, more particularly a molecule comprising at least one atom having at least one cationic charge.

In this regard, it will be observed that a chemical compound intended to cationize a micelle 3 may consist of a quaternary ammonium derivative or of a molecule having at least one quaternized nitrogen atom. By way of example, such a chemical compound may consist of a cationic surfactant, more particularly chosen from alkyltrimethylammonium halides, benzethonium halides and cationic derivatives of nitrogenous heterocycles.

Such a cationic chemical compound can also be derived from monomers chosen from the following monomers:

Finally, and as mentioned above, this composition contains a solvent of the organic type (oil, alcohol, ketone or the like) and / or mineral (water or the like).

Examples of application, formulation and results obtained:

I Insecticidal treatment of a textile support:

The treatment consists of applying a chemical composition containing permethrin-based insecticidal active molecules to a textile support consisting of a 100% polyester knit with a basis weight of 35 g / m ² . The target amount of permethrin to be fixed on the support is 1000 mg / m2. The effective concentration of permethrin on the support depends on the concentration of insecticide in the bath and the transport rate

(amount of bath carried by the support).

The fixing process consists of:

an insecticidal chemical composition containing: 1. 98 g / liter of a permethrin formulation in a 50% emulsion;

2. 20 g / liter of a nonionic binder;

3. 2 g / liter of a nonionic wetting agent; 4. 60 g / liter of a quaternary ammonium derivative; 5. 2 g / liter of an 80% acetic acid solution.

a textile support is treated by impregnating this support on a beaker; the active element is dried on a train at a temperature of 120 ^° C.

By proceeding as described above, a carrier rate of the order of 65% (0.65 liter of bath / kg of textile support) is observed.

Results obtained:

Long-term remanence of an insecticide impregnating a net

Test method:

Mosquitoes of a susceptible strain of Anopheles gambiae ss are exposed for 3 minutes to the tissue to be tested. Geigy cages are used for this purpose. Females three to five days old, not siphoned, are introduced in sets of 11 in the cages. A total of 44 females are used to test each sample. The tests are conducted at a temperature of between 23 ^° C. and 25 ^° C. at 50% to 70% relative humidity. The observation made during the 24 hours following the introduction of mosquitoes into the cage is carried out at a temperature of 28 ^° C. at 70% relative humidity. Results

Objects: Tulle EO, El, E2; made green tulle

• The washes were made according to the ISO 6330 textile standard at a temperature of 40 ^° C.

• Kd means knock down = Abatement effect.

KD is the number of mosquitoes that respond to the effect of the insecticide. The latter show signs of weakening and are unable to sting.

• 3 'kd: The kd is checked after 3 minutes of observation.

• Ih kd: The kd is checked after 60 minutes of observation.

• 24h effective mortality: Number of mosquitoes killed after 24 hours of observation.

II Neutralization treatment of odors of a concrete support:

The treatment consists in applying a chemical composition containing active molecules intended for neutralization odors based on a mixture of geraniol and eugenol on a concrete support. The effective concentration of the mixture of geraniol and eugenol to be fixed on the support depends on the concentration of the mixture in the bath, the level of odor to be neutralized and the amount of bath deposited on the support.

The fixing process consists of:

a chemical odor neutralization composition is prepared containing: 1. 739 g / liter of a formulation of a mixture of geraniol and eugenol in emulsion at 30%;

2. 200 g / liter of a nonionic binder;

3. 1 g / liter of an anti-foam agent;

4. 50 g / liter of a quaternary ammonium derivative; 5. 10 g / liter of an 80% acetic acid solution.

a concrete support is treated by spraying this support;

the active element is dried at ambient temperature (between 20 ^° C. and 25 ^° C.).

Results obtained:

Long-term retention: Odor neutralization treatment has been effective for up to 10 weeks.

Note: In the case where the odor neutralization treatment is carried out without a fixing system (application only of the mixture of geraniol and eugenol), the odor neutralization treatment is effective for a maximum duration of 4 to 5 days.
