Definitions
- the present invention relates to a granular composition for cat litter.
- compositions for cat litters are generally granular products that should have a good property of absorbing liquids, abating odours and environmentally friendly and easy disposal. All the above mentioned characteristics depend upon the kind of material used, more particularly grain size, density and chemico-physical properties.
- sea foam which is a highly absorbent product adapted to absorb up to 90% of its weight and indeed only 10-15% is transformed into slush
- bentonite having a good absorption (equal to 70% of its weight) but also a very low hardness so that in contact with urine it forms unpleasant round slush lumps that must be taken out from the container tray any time these lumps are formed because besides being unaesthetic, evil-smelling and sticky to the cat paws, they are also a hindrance for the animal who does not urinate until litter is being cleaned
- tuff that on one hand has a high hardness and generates only a little percentage of slush, on the other hand having a poor absorption (between 50 and 60%) causes liquid to remain on the tray bottom generating unpleasant odours
- synthetic products of natural elements and the above mentioned compounds in order to lighten the material and make it more easily disposable.
- an object of the present invention is to provide a material having a high absorption, adapted to abate odours and at the same time prevent slush formation.
- Another object of the invention is to provide an environmentally friendly material that can be easily and readily disposed by the user, anti-bacterial and easy to be removed by the cat.
- the granular composition for cat litter comprising a cellulose based vegetable products and a salt of acidic pyrophosphate with an alkaline or alkaline earth metal according to the features of claim 1.
- cellulose based vegetable product means a compound obtained by processing wood mainly comprising cellulose .
- the cellulose based vegetable product according to the invention is preferably selected from the group comprising wood pulp, wood shavings, corn cob (corn cellulose), paper and cardboard. Different kinds of trees may be used for producing the mentioned vegetable products and more particularly poplar and birch tree. More preferably the vegetable compound is selected from wood shavings and wood pulp, the latter being most preferred.
- the alkaline or alkaline earth metal used as cation in the salt with acidic pyrophosphate is sodium.
- Acidic sodium pyrophosphate is a salt mainly used as leavening agent for cakes or additive for tooth paste. It is used in the composition according to the invention in a water solubilized form in an amount equal to ratio to water 50-70: 50-30 and an amount of 0.2-0.9% to the cellulose based vegetable product, preferably 0.5%.
- the vegetable product is wood pulp 0.5 g of acidic pyrophosphate are needed for 1 kg of wood pulp. Further additives such as anti-mould, deodorant, flavouring agents may also be added to the composition of the invention.
- composition of the invention contains wood pulp as cellulose product ethanol is preferably added as anti-mould agent, being preferably added in an amount of 1% for 1 kg of wood pulp.
- composition according to the invention are due to interaction between acidic sodium pyrophosphate and the urine components such as ammonia, thus abating the unpleasant odour and uric acid.
- reaction is slightly exothermic and this avoids transudation phenomena that are the reason of slush formation.
- the vegetable litter produced with the composition according to the invention is a granular product having a density of 180-250 g/1, in which grain size is in the range of 2 to 10 mm. Such a broad grain range is provided to obtain a balance between ability of mixing with liquid and solid dung. Indeed, the fine particles stay by gravity on the bottom of the tray absorbing the greatest percentage of liquids. Moreover, when the cat digs in the litter to cover his dung, the dung comes into contact with the finer particles so as to eliminate odours.
- the litter granule has a generally flattened shape and has an absorbing capacity of 600-700%, preferably 648%, is very light, inert and odourless.
- As the granule consists of a cellulose based composition, it can be easily disposed because it can be discharged and disposed through the home toilet like toilet paper.
- the granules of the invention are very absorbent, they keep their solidity and grain size. This feature together with lack of transudation, gives to the litter according to the invention a longer useful life in comparison with the known litter products.
- the granular product according to the invention generally has a white colour.
- the vegetable product used is wood pulp
- its properties can be exploited to check the condition of the granular product.
- dry wood pulp is white and turns more and more pink when being hydrated. Therefore, when the product has a marked pink colour, the useful life of the granular product is over.
- a vertical drier with forced circulation (fluidised bed) fed with liquid propane gas or methane gas is being used.
- wood pulp undergoes a proper screening and the obtained granular product having a grain size of 2 to 10 mm is directly sent to a suitable silo.
- the granular product is sent by conveyor belt to a spraying booth for the addition of a mixture of water and pyrophosphate in a percentage of 50% and ethanol in the minimum quantity of 1% as anti-mould agent.
- the litter according to the invention has the further advantage to allow recycling during the production cycle.
