Description

DETAILED DESCRIPTION OF THE DISCLOSURE

[0015] The present invention is about a biocide product, of continuous and prolonged effect that comprises alcohol as a biocidal agent of immediate action, copper nanoparticles as biocidal agent of prolonged effect and a quaternary ammonium, particularly benzalkonium chloride, as biocide of intermediate action.

[0016] The different formulas that may be prepared, in liquid as in gel, all of them contain alcohol, quaternary ammonium and copper nanoparticles in a determined range of proportions.

[0017] A preferred aspect of the present invention is that the final biocidal product to contain a proportion of alcohol between 65% and 75%, quaternary ammonium between 0.05% and 2.25% and copper nanoparticles between 5 to 100 ppm (parts per million).

[0018] It is also another preferred aspect that the alcohol used as biocidal to be ethanol, and that the quaternary ammonium to be Benzalkonium Chloride (Alkyl-benzyl-dimethyl ammonium chloride).

[0019] One of the formulas of the present invention, —biocide gel of prolonged effect—is embodied in the following manner: 23.85 ml of demineralized water at 40° to 50° centigrade is poured in a tank, that we shall name main tank. A dispersion of nanoparticles in water, with 0.001 gr. of copper nanoparticles in demineralized water is prepared in an auxiliary tank, and it is stirred for at least 2 minute at 3000 rpm.

[0020] The stirrer of the main tank is started, acting at 1400 rpm and the mentioned previously prepared dispersion of nanoparticles is poured without stopping the stirrer. Immediately, the gelling powder is added in a quantity of 1.1 gr, in a slow motion and continuous stirring so as to prevent the formation of lumps. The stirring is continued in the main tank for 10 to 15 minutes until a homogeneous and transparent gel is obtained. Without interrupting the stirring 0.06 ml. of benzalkonium chloride in the form of a solution at 80% is added. Then ethanol 65 ml is added on the main container and stirred until the total content of the batch (100 ml) is completed, stirring is continued for at least 15 minutes more. Following exactly said steps and the proportions of the components the manufacturing of the biocide gel product of prolonged duration is obtained.

[0021] Thus a preferred formulation that can be applied on the skin comprises, for 100 ml of the final product: Ethanol 70% (70 ml), Benzalkonium Chloride 0.05% (0.05 ml); copper nanoparticles 10 ppm (0.0001 gr), demineralized water 29.95% (29.95 ml).

[0022] Another embodiment of the present invention comprises a liquid formulation where the same steps as aforementioned are repeated but without the use of the gelling agent.

[0023] The use of the biocide in the liquid formula results more apt to be applied on surfaces and the gel formulation for personal use especially on the skin.

[0024] The following formulation is preferred to be used on surfaces, furniture and facilities for 100 ml of the final product: Ethanol 60% (60 ml); Benzalkonium Chloride 0.25% (0.25 ml); Copper nanoparticles 10 ppm (0.0001 gr), demineralized water 39.75% (39.75 ml).

[0025] Such as it has been described, the invention has multiple uses not only personal use for hands and skin but also on surfaces for support and contact for domestic use, countertops and furniture for commercial and industrial facilities, interior of means of transport (private or public), healthcare facilities, schools, etc., due to its wide range and prolonged duration of its biocidal effect.
