Abstract

The invention concerns a novel litter for animals. Preferably, said novel litter comprises an absorbent substance such as sawdust and a disinfecting substance such as sodium perborate, the sawdust having a grain size distribution between about 500 and 1100 νm. The invention is characterised in that the litter provides both safety for the users (the animals and their owners) and highly respectful of the environment.

Description

ANIMAL LITTER

The present invention relates to animal litter, especially domestic, such as cats and dogs, or laboratories.

It exists to this day many litters formulations offered to users generally made of an absorbent material to which various substances (virucidal, fragrant ...) are added.

These formulations are however not without defects; thus adding an odorant only masks the odor, at times heavy, feces and urine of animals. In addition, such formulations do not attach enough to maintain user safety (including the owners of these animals and their families) and respect for the environment within the premises where these are collected feces and urine or outside when it comes to dispose of used litter.

Litter subject of the present invention has no such defects but rather is associated with benefits to its membership; it ensures both the safety of humans and animals and respect the environment.

With regard to the absorbing material, the inventors have preferred not to use minerals: these latter are difficult to remove and furthermore pollute the environment trays where litter are arranged; cats have such a habit of covering their droppings with a part of the litter, throwing some of it out of the tank where it is: it is then almost inevitable to walk on the granules thus ejected and crush , creating a sticky dust to users slippers or shoes. These minerals, clay-based, for example, are only weakly absorbent, and liquid often form sludge with very fine particles from these substances.

Thus according to the invention, the absorbent material will Does composed of a product based on wood (cellulose-lignin).

Preferably, this product has been dried beforehand (3OO-5O0 ° C for example), sieved and dedusted.

The Applicant has found that the best particle size product was between 500 and about 1100 microns.

Such a particle size allows particular intimate admixture with disinfectant substances such as sodium perborate the particle size is preferably chosen close to that of the absorbent compound. The proportion between absorbing compound / disinfectant substance is provided so that a residual pH of approximately 9 is maintained after hydrolysis of the urine and faeces by the disinfectant substance; it was noted that the hydrolysis was effected regularly mainly because of the homogeneity of the mixture in terms of size. Preferably an aliphatic amide, such as the Tetra Acetyl Ethylene Diamine (TAED) having a sanitizer role, will be added to the mixture.

The composition object of the present invention, due to its qualitative and quantitative characteristics, allows to maintain the basic pH supra, which has the following advantages: inactivation, irreversibly, of the micro-organic flora (it has tested this inactivation persisted 18-24 months after using the litter) bacteriostatic

- neutralizing the usual routine anaerobic, thus preserving environmental impact of any nosocomial.

Another advantage of the composition object of the present invention is that it avoids the phenomenon of caking particularly troublesome in the case of traditional litter.

In addition, it will be particularly important to avoid "fines" or dusts in particular of absorbing compound: these can indeed present many disadvantages; in household dust in increased transmission of germs through aerosol (eg toxoplasmosis), while in the laboratory, the dust quickly clog filters cleanroom which houses animals. Thus the "infectious" transmission and / or "infecting" the animals to humans will be particularly low (which is not the case for traditional bedding). The environment will also be preserved, the final mixture is easily incinerated, biodegradable and compostable, representing environment in terms a decisive advantage over existing bedding.

Security bedding forming the subject of the present invention in particular due to the basic pH as has already been mentioned: up to the absorptive capacity of the absorbent compound, oxidation with sodium perborate provides bactericidal efficacy some, and beyond this absorption capacity, the residual salinity pH 9 provide a bacteriostatic warranty.

By way of non-limiting example, the Applicant has realized a mixture comprising: - from about 80% wood sawdust in the range of 17% sodium perborate

The supplement is provided by the DAT, these various percentages being by weight of the mixture, and the preferred particle size that has already been cited in the present description.

Also preferably, sawdust, previously treated as indicated, come from spruce.
