REPELLENT COMPOSITION FOR BIRDS

DESCRIPTION

Technical field

The present invention relates to a repellent composition for birds, characterized in that it exhibits zero toxicity for both birds and people. It is also the object of the invention to use said composition as a repellent for all types of birds, such as seagulls or pigeons.

Background

City birds (seagulls, pigeons, etc.) may occasionally occupy spaces such as terraces and roofs in urban buildings, where they become a source of noise and dirt, causing hygienic-sanitary problems. To avoid these discomforts, different devices and compositions have been devised especially suitable to scare away these types of birds.

Thus, for example, in the international application WO / 2013/070441 a composition and method for controlling populations of wildlife (including domestic animals) and pets, such as birds, are described. Specifically, the repellent formulation described in this application is characterized by comprising from 0.05 to 30% by weight of geraniol oil.

For its part, application CN103548865 refers to a repellent composition for birds in the form of a micro-emulsion or an emulsion with a suspension of microcapsules, as well as to its method of preparation. In this case, the composition object of this application is characterized by comprising three or four compounds selected from methyl anthranilate, nerol, ethyl cinnamate, cinnamaldehyde and / or cinnamamide.

However, although there are suitable commercial repellents to scare away birds or other animals, most of the products that currently exist have the disadvantage of being toxic to birds, even causing death. It is therefore the object of this invention to present a new composition that, in addition to being repellent for all types of birds (such as pigeons or seagulls), does not cause any damage. It is therefore a composition characterized by zero toxicity in animals or people, so that their accidental intake would not cause them any kind of damage.

Likewise, compared to other solutions of the state of the art, the composition object of the present invention offers the advantage of being able to be applied in all types of locations, giving solution to a great variety of hygienic-sanitary problems. In this way, it can be used in economic sectors or locations as diverse as hotel facilities, town halls, neighborhood communities, airports, industrial buildings and, ultimately, in any facility that may be affected by adverse effects or damages caused by the presence of birds, such as seagulls or pigeons.

Detailed description of the invention

It is therefore a first object of the present invention a new bird repellent composition obtainable from a process of mixing the following ingredients:

. from 0.25 to 0.50% w / v (preferably 0.3 to 0.4% w / v) zinc chloride,

. from 0.1 to 0.25% w / v of 3-bromo-5-chloro-2-hydroxyphenylmethane,

. 0.1 to 0.30% w / v (preferably 0.15 to 0.2% w / v) methane,

. from 0.01 to 0.50% w / v (preferably 0.02 to 0.4% w / v) of a first alcohol consisting of menthol,

. from 0.01 to 0.03% w / v sodium saccharin,

. 0.1 to 0.3% w / v vinegar (solution of 3 to 7% w / v acetic acid in water),

. from 0.01 to 0.2% w / v of a second alcohol other than menthol (preferably ethyl alcohol and more preferably ethyl alcohol with 96% purity) and. water, in the amount necessary to complete 100% of the composition.

As indicated above, the composition described above is completely harmless to birds, achieving the objective of chasing them away without causing them any harm.

In an especially preferred embodiment of the present invention, the composition can be obtained from a mixture of the following ingredients:

. 0.35% w / v zinc chloride,

. 0.25% w / v 3-bromo-5-chloro-2-hydroxyphenylmethane,

. 0.2% w / v methane,

. 0.02% w / v menthol,

. 0.02% w / v sodium saccharin,

. 0.1% w / v vinegar,

. 0.02% w / v of an alcohol other than menthol (preferably ethyl alcohol and more

preferably ethyl alcohol with 96% purity), and. water, in the amount necessary to complete 100% of the composition.

The composition of the present invention may be presented as an aqueous solution, concentrate, foam or aerosol, among other examples.

Preferably, the process of obtaining the non-toxic repellent composition for birds as described above can be carried out according to the following steps:

(1) a first stage of mixing zinc chloride, 3-bromo-5-chloro-2-hydroxyphenylmethane, methane, menthol and sodium saccharin, followed by a second resting stage, preferably at room temperature (approximately 25 ° C) and for a time preferably between 20 and 50 minutes (and more preferably, 30 minutes); Y

(2) a third stage of vinegar addition and a mixture of a second alcohol other than menthol (preferably ethyl alcohol and more preferably ethyl alcohol with 96% purity) and water, followed by a fourth resting stage preferably at room temperature (approximately 25 ° C) and for a time preferably between 50 and 70 minutes (and more preferably 60 minutes).

The proportions of the different components in the mixture will be those indicated above.

As a consequence of the resting stages of the process, a correct combination between the different components used to prepare the composition is achieved, giving rise to the appropriate chemical reactions to achieve the final product.

Likewise, the use of the claimed composition as a non-toxic repellent for birds is a further object of the present invention.

The composition of the present invention can be applied in at least one area affected by the presence of birds by different methods such as impregnation, coating, immersion, soaking, spraying and / or fogging of at least one surface or area to be treated.

Examples

In order to demonstrate the effectiveness of the claimed composition in its use to scare away birds, a series of experimental tests were carried out in the field. The following examples show the results obtained in these tests, which further demonstrated the zero toxicity of the composition in birds and humans over a period of 6 months.

Example 1. Use in private homes

In this first example, the effectiveness of the composition was determined when applied in a private home affected by the presence of birds (particularly seagulls).

To carry out the test, the composition object of the invention was prepared according to the method described above. Specifically, to prepare a 100 ml composition, the following ingredients were mixed in the amount indicated below:

. 0.35 g of zinc chloride;

. 0.25 g of 3-bromo-5-chloro-2-hydroxyphenylmethane;

. 0.2 g methane;

. 0.02 g of menthol; Y

. 0.02 g of sodium saccharin.

Once the mixture of the above components was obtained, it was kept at rest for a time of 30 minutes at room temperature (25 ° C). Next, 0.1 g of vinegar, 0.02 g of ethyl alcohol 96% purity and water were added in an amount sufficient to reach 100 ml as the total volume of the composition. Finally, the composition obtained was kept at rest at room temperature (25 ° C) for a period of 1 h.

Once the composition was prepared, an absorbent cloth (cloth) was impregnated with it and its application was applied to the surface of an outdoor terrace exposed to the presence of birds.

After one hour, the total absence of birds was checked.

This same trial was performed over a period of six months. Throughout this period, the absence of birds was total on the surface on which the composition had been applied, demonstrating its effectiveness.

Example 2. Use in commercial area

The same test was carried out by applying the composition on the terrace of a cafeteria located in the center of a coastal city in northern Spain.

In this case, a cloth was moistened with the non-toxic repellent composition for birds prepared as described in example 1 and applied on the surface of each and every one of the terrace tables.

10 After one hour the total absence of birds (seagulls and pigeons in particular) in the affected area was verified. The composition was tested over a period of six weeks to determine its effectiveness. In all the tests performed, the total absence of birds was verified. In particular, the birds remained on cornices or balconies 4 or 5 meters away from the terrace, but did not approach at any time the tables where the application of the composition was carried out, demonstrating its effectiveness.
