DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a means which effectively combats and neutralizes disagreeable odours from animal excretions and excrement.
It is known that it is very difficult to get rid of disagreeable odours due to animal excretions especially in the case of domestic animals, particularly cat urine and excrement, but also the odours from excretions from farm animals such as pigs, cattle, sheep, rabbits, poultry and other farmyard animals.
In the particular case of cat urine and excrement, their odour is particularly clinging and persistent. It turns out that whatever the perfuming or deodorising agent used to neutralize these disagreeable odours, these reappear after a certain time once the perfume's or deodorant's own odour has disappeared through evaporation. Indeed, in centres where animals such as pigs, cattle, sheep or rabbits are bred, the odours emanating from the pens or locations occupied by these animals are not, in general, dealt with due to a lack of effective means.
The present invention now provides a means having the effect of either preventing development of an odour after an animal has discharged or deposited its excretions or excrement on its litter, manure gulley or any other surface, i.e. as a preventive measure, or effectively combatting by neutralizing disagreeable odours which have already developed either on a surface or at a location following deposition by domestic or farm animals of excretions or excrement or accumulation of these excretions or excrement.
Accordingly, the present invention covers compounds having its effect and characterised by the fact that they belong to the family of compounds usually used in perfumery for their odoriferous properties but having, in addition, a vapour tension of less than or equal to 4 Pa at 25.degree. C.
The invention also covers applications of these compounds as well as formulations containing at least one of these as will be made more clear from the following description.
In general, compounds selected from the following may generally be cited as falling within the scope of the invention: decanol, citronellol, geraniol; as normal or branched dodecanal, myrac aldehyde or aromatics such as cyclamen aldehyde heliotropine, para-methylphenylacetaldehyde, vanillin and its derivatives; beta ionones and damascones as well as aliphatic and aromatic ketones having a musk-like odour and having up to 18 carbon atoms; dihydrojasmonate, methyl jasmonate, methyl cinnamate, ethyl methylphenylglycidate, aromatic esters, such as methyl anthranilate, methyl N-methyl-anthranilate, p-cresyl phenylacetate, amyl salicylate; lactones, such as gamma-decalactone, dodecalactone and undecalactone; naphthol, galaxolide; with hydroxycitronellal termed indolene, and aliphatic nitriles, such as tridecene-2-nitrile; 2-(2'-methyl-pent-2'-enyl)-5-methylpyridine.
Among the compounds mentioned above, coumarin, allylionone, eugenol and iso-eugenol, methyl dihydrojasmonate, indole and indolene, helional, alpha- and beta-ionone and 2-(2'-methyl-pent-2-enyl)-5-methylpyridine are cited preferably.
Those compounds which are liquid may be used as they are. On the other hand, crystalline compounds are used following dissolution in their usual solvent, well known in perfumery, such as ethyl phthalate, benzyl benzoate, ethyl citrate and their analogues.
In addition, if desired the compounds according to the invention may also be used in combinations in variable proportions giving a formulation having practically no disagreeable olfactive effect.
There is, however, nothing to prevent augmenting the olfactive effect of the formulation for application on the user or environment by adding other primary perfuming substances to the compounds according to the invention, taken singly or in combination.
The following examples are given by way of illustration and in no way limit the type of formulations which may be prepared producing prevention or effective neutralization of disagreeable odours resulting from excrement and/or deposits and/or the accumulation of animal excretions. Of course,
