Description
129~96 The present invention relates generally to pesticide varnishes and paints acting by contact. ~ore particularly, the invention relates to active concentrates for forming such varnishes and paints, as well as the method for manufacturing them.
In French paten~ No. 1 050 895 a method has already been described for manufacturing contact insecticide varnishes and paints, the activity of these products being due to the concept according to which the film formed after drying maintains sufficient porosity for the active insecticide product to migrate towards the surface under the effect of the surface tension of the base, due more especialIy to the polarity of one of its constituents.
In French patent No. 71 39 852 published under No.

In French patent No. 71 39 852 published under No.
2,166,438, a method has also been described for manufacturing a contact insecticide varnish, intended more specifically for treating wall papers or other wall covering support medium. This me-thods consists in dissolving or dispersing at least one appropriate insecticide product at the rate of 1 to 12~ by weight in an organic polar solvent compatible with said insecticide, at a temperature less than 80C, then incorporating the solution or emulsion thus obtained in a base for varnishes, compatible with the polar solvent, at the rate of 15 to 45% by weight.
It should be noted that the insecticide activity by contact thus o~tained results from the presence of active crystals flush with or projecting from the polymerized surface in the mesh of which they are imprisoned, after migration of the active product and evaporation of the solvent. Thus, since the active product does not volatilize in the atmosphere, its r ~d ,. , ' ~29~L29~;
1 remanence is very high and results in several years of efficiency.
Now, during such a period, the applicant was surprised to discover that, besides its expected and normal insecticide and pesticide activity, and insecticide paint such as described above could have an activity on certain acarides, which was revealed following numerous examinations of cases where users having certain asthmatic diseases and living in premises treated with such a paint found relief. It is in fact known that the majority of asthmas is due to acarides, against which the sufferers fight at the present time using passive measures of desensitization, or more active measures by removing furnishing elements likely to shelter acarides, or by means of acaricide solution sprays, which must however be renewed constantly because of their volatility and because of the incubation period relative to the reproduction of said acarides.
SUMMARY OF THE INVENTION
The applicant has therefore sought to modify his product and his manufacturing methods so as to obtain a tighter mesh capable of incorporating crystals of a specifically acaricide agent with appropriate distribution so as to act by contact and further to provide an additive in concentrated form for a suitable base, which improves the cost and the ease of manufacture as well as the flexibility in use.
In acaordance with the invention, a pesticide-acaricide concentrate is formed by a 50~ by weight saturated solution or suspension of at least one . .
~9~x9~
1 pesticide and one acaricide in a polar solvent, said concentrate being intended to form about 4 to 10% by weight of a paint base.
According to an advantageous characteristic, a second concentrate is formed by a solution of a fungicide, the purpose of which will be made clearer hereafter, for forming about 0.5 to 1.5~ by weight of the paint base.
Other characteristics and advantages of the invention will be clear from the following description, given by way of explanation which is in no wise limitative.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The pesticides applicable in accordance with the invention are in the general class of organo-phosphorated, organo-chlorated compounds or photostable synthetic pyrethrinoids, and decamethrine may be cited by way of example. It should be noted that the pesticides must have the following properties: absence of acute toxicity, low vapor tension, good remanence, insolubility in water and, of course, compatibility with the paint base, this latter being of the vinylic, acrylic oe fatty type. As polar solvents, there may be mentioned by way of example: butanol, toluene, xylene, isobutyl acetate, oil of turpentine etc.
Although, as was discovered by the applicant during his research work, the organo-chlorated compounds have in general a certain acaricide activity, lindane or gamma-hexachlorocyclohexane seems the most speci~ically efficient and it is included in the '`~"?' ~.~9~296 -3a-1 composition of the pesticide-acaricide concentrate at the rate of 5 to 10% by weight.
The second concentrate mentioned above has essentially fungicide properties. During his work aimed at obtaining a contact acaricide product, the applicant in fact found that the asthma generating . ~
, , '''. ' ':
~91~9~
, 1 acarides develop preferentially to the detriment of mildews supplying them with their nutritional medium. Under these conditions, the applicant thought of further improving his product by going beyond the destruction of the living organism, by the very destruction of its nutritional medium and thus by reduction of its capacity to proliferate. The fungicide, known per se, is formed by a N-heterocyclic compound. In any case, the presence of the fungicide proves useful in a pesticide paint applied in premises where there is a risk of development of mildews, so as to prevent these latter from partially digesting the organic products of the layer and thus degrading the paint coating.
The method of manufacturing the pesticide-acaricide concentrate is similar to that described in the above mentioned French patent No. 71 39 852 for the insecticide varnish. In accordance with the invention, a 50% by weight saturated solution or emulsion of pesticide and acaricide is formed in the polar solvent, when warm but at a temperature less than 80C, so as to obtain an homogeneous dispersion, and if required a dispersent agent is added, for example that sold as "Calgon" (registered trade mark). The concentrate thus obtained may be kept and transported without difficulty and may serve subsequently as additive to a paint, in the above mentioned proportions.
This concentrate may also be incorporated immediately in the paint base for direct manufacture of this latter, with the same proportions. In so far as the fungicide concentrate is concerned, it may be incorporated in the base under the same conditions, either at the time of use, or directly for obtaining a paint.

The present invention has of course been described solely by way of explanation and is in no wise limitative and any useful modification may be made thereto, particularly in the field of technical equivalences, without departing from the scope and spirit of the invention.
