Embodiment 1

[0082] In the first series of tests, four samples of insect repellent compositions were prepared in which:

[0083] - two "control" samples WW1, WW3 (aqueous solvents), each comprising 87.25% by weight of water and 0.25% by weight of a surfactant based on sodium lauryl sulfate (SLS), and:

[0084] o for sample WW1: 12.5% ​​by weight of lauric acid;

[0085] o for sample WW3: 37.5% by weight of lauric acid;

[0086] - Two "test" samples WL1, WL3 (non-aqueous solvents), containing:

[0087] o For sample WL1: 43.75% by weight ethanol, 43.75% by weight isopropyl myristate (MIL) and 12.5% ​​by weight lauric acid;

[0088] o For sample WL3: 31.25% by weight ethanol, 31.25% by weight isopropyl myristate (MIL) and 37.5% by weight lauric acid.

[0089] In particular, the "test" samples contained about 0% by weight water such that they each formed anhydrous compositions.

[0090] Each of these four samples WW1, WW3, WL1, WL3 were tested according to the above experimental protocol, ...

Embodiment 2

[0095] In the second series of tests, seven samples of insect repellent compositions were prepared, each without water and containing:

[0096] - insect repellent ingredients comprising lauric acid and / or another type of insect repellent ingredient;

[0097] - a non-aqueous solvent comprising:

[0098] o ethanol (41.75%-48% of the total weight of the composition); and

[0099] o Isopropyl myristate (MIL) (41.75%-48% of the total weight of the composition).

[0100] Of these samples, four "control" samples WL1, W4, W11, W8 were provided, each containing a single type of repellent ingredient. thus:

[0101] - sample WL1, similar to the sample prepared during the tests of the first system, containing lauric acid (12.5% ​​by weight);

[0102] - sample W4, containing p-menthane-3,8-diol (PMD) (3% by weight);

[0103] - Sample W11, containing N,N-diethyl-3-methylbenzamide (DEET) (3% by weight);

[0104] - Sample W8, containing essential oil of striking lavender (4% by weight). ...

Embodiment 3

[0113] In the third series of tests, four samples of an insect repellent composition were prepared, each sample was free of water and contained:

[0114] - insect repellent ingredients comprising lauric acid and / or another type of insect repellent ingredient;

[0115] - a non-aqueous solvent comprising:

[0116] o isooctyl succinate (64.80%-79.80% of the total weight of the composition); and

[0117] o A mixture of coconut alkanes, caprylic and capric cocoyl esters (16.20% by weight of the total composition).

[0118] Of these samples, two "control" samples ASPF07, W12 were provided, each containing a single type of repellent ingredient. thus:

[0119] - sample ASPF07 contains ethyl butylacetamidopropionate (IR3535) (4% by weight);

[0120] - Sample W12 contains icaridin (4% by weight).

[0121] In addition, two "test" samples ASPF08, WL12 were provided, each containing lauric acid (12.5% ​​by weight) in the same proportion as sample WL1, in combination with one of the tw...

Abstract

An insect-repellent composition is provided, comprising: an insect-repellent compound comprising one or more fatty acid(s) having between 9 and 21 carbon atoms, a non-aqueous solvent, and less than 1%by weight of water.

Description

technical field [0001] The present invention relates to an insect repellent composition comprising one or more fatty acids having 9-21 carbon atoms. [0002] The present invention is particularly suitable for compositions having a repelling function against harmful insects, such as stinging or biting bloodthirsty insects, such as mosquitoes. Background technique [0003] Such compositions are generally intended to be applied directly to the skin of a subject, or indirectly to the air or other surfaces, for example by means of a sprayer, ball applicator, or other means of application. implement. [0004] For example, from document US-5 594 029 is known a composition intended for topical application to the skin or clothing of human or animal subjects, said composition comprising coconut oil used for its insect repellent properties fatty acid. [0005] Likewise, a composition is known from document WO-00 / 72676, especially intended to be applied to the skin and / or clothing of...
