Description
A MULTIFUNCTIONAL SINGLE PRODUCT FOR DETERGENT
FORMULATIONS.
BACKGROUND OF THE INVENTION.
A. FIELD OF THE INVENTION.
This invention refers to a multifunctional single product for detergent formulations, and more particularly, to a product in the form of a powder or a glass, which is water soluble and acts as builder, conditioner, filler and carrier, among others, in the detergent and in the process for its manufacture.
B DESCRIPTION OF THE RELATED ART.
The most common oxides that are required for the production of detergents are: phosphorus oxide (PZOS), sodium oxide (Na20), silica (SiOZ), as well as other additional ingredients such as boron oxide (8203) and others.
These oxides are normally provided through a plurality of raw materials or chemical compounds, such as the sodium carbonate (Na2C03), sodium tripolyphosphate (Na5P30,o), sodium sulfate (NaZS04), sodium silicate (xNa20.ySiOz) and sodium borate (Na2B,0,).
It is known that each detergent producer has its own formulations, but each producer normally buys and uses the above-mentioned typical chemical compounds as raw materials.
Researching on the roles or functions performed by each of these compounds, applicants found that each of such compounds performs a task, acting as a builder, as a conditioner, as a filler, as a carrier, as a neutralizing agent, etc. in the detergent and for in the process for its manufacture.
Considering that the high number of raw materials which has to be used for each formulation (imparting their respective roles), increases the cost of production of the detergents, (actually, most of the detergent producers have to buy from at least 5 to 8 or more raw materials or reagents to define their formulas), applicants conceived as a goal, the development of a single new multifunctional product for the production of detergents, that would include most of the typical oxides normally included in the detergent formulations, complying with at least some of the main functions, which could perform as the original chemical reagents, which could be soluble in water, and which could reduce the cost of the raw materials.
- l0 To that purpose, applicants observed that the sodium tripolyphosphate, a raw material normally used in the detergent formulation as a source of phosphorus oxide (P205), is made by reacting phosphoric acid with sodium carbonate; that in turn, the phosphoric acid is obtained from the reaction of the grounded phosphoric rock with sulfuric acid, which is filtered for impurity elimination which is not but silica which is also present in the detergent formulation; and that the sodium carbonate is normally obtained by a process for the benefitiation of the trona ore by impurity elimination which is not but silica which is also present in the detergent formulations.
Therefore, applicants concluded that, if the impurity compounds are also materials present in the detergent formulations, and that the process for their elimination add a cost to the raw materials and consequently to the final detergent, then the mineral treatment to obtain such raw materials becomes unnecessary and the phosphoric rock or at least the phosphoric acid can be used, through just a partial treatment (such as acid or alkaline attack, as well as grounding, sieving and screening), to produce a product which would be used as a source of P205 and as a partial source of Si02 in the detergent formulations.
The Na20 is provided through the sodium carbonate obtained from the treatment of trona mineral by a process including grounding, diluting, filtering to eliminate compounds considered as impurities (which are compounds also used in the detergent formulations) and crystallizing, to obtain the sodium carbonate. Again, applicants concluded that it would be unnecessary to treat the mineral to eliminate something that will be also needed in the detergent l0 formulations, and the trona mineral could be used directly, through a simple grounding. step, at more reduced costs, to prepare a single product which would be adjusted to the detergent formulation needs.
The Si02 is provided through the sodium silicate which is obtained from reacting silica sand and sodium carbonate in a furnace. The multifunctional product developed by applicants will provide the silica that the detergent formulation needs.
In other words, through a single mixture of balanced and treated primary raw materials or minerals which include the sources of oxides for the detergent formulations and a reaction of them in a furnace, it is possible to provide a single multifunctional product for whatever detergent formulation needs.
With such a product, the detergent producer will have not the need to buy 5 or 8 different raw materials for its formulation, but a single product which is less expensive because it will not include the costs of the purifying processes incorporated in each raw material and because such a product involves just one process, instead of each process to produce each of the actual raw materials.
This product will provide the oxide needs for the detergent formulation and for its manufacturing process and will perform the essential roles or functions such as builder, conditioner, filler, carrier, neutralizing agent, etc. in detergent formulations and in its manufacturing process.
Therefore, Applicants found that, by mixing natural or partially treated (grounded or comminuted) primary raw materials or minerals comprising phosphoric rock, trona, silica sand, sodium sulfate and/or other intermediate products such as phosphoric acid and sodium bicarbonate, in proportions according to the needs of a specific detergent formulation, and introducing them into a furnace for reacting them, results a single product in the form of: a powder, if the furnace is operated at a lower reacting temperature without melting; as a glass, if the furnace is operated at a reacting and melting temperature; or as a liquid, if the product is solved after it has been obtained as a powder or glass.
This product can also be used in the processes for producing detergents, instead of all the raw materials used in the conventional processes, to achieve each of the roles or functions as builder, carrier, filler, among others.
Thus, the obtained product is soluble in water and it will perform the essential roles or functions such as builder, conditioner, filler, carrier, etc. in detergent formulations and in its manufacturing process and results less expensive than the raw materials normally used.
Furthermore, as it is also known, the detergent producers changed their process technology to produce detergents in the tower process and in the agglomerate process. In both cases they needed almost the same type of raw materials, however they needed solid and liquid raw materials such as sodium tripolyphosphate and sodium silicate. Applicants found that another advantage 5 that the detergent producers can obtain from the product of the present invention, is that this product allows to control the relation of all the oxides, such as P20~/ Na20/Si02, in a most wide range than by using only the respective raw materials, and will provide just a solid or liquid product.
And last, but not least, with the product of the present invention, the l0 detergent producer does not have to pay for multiple raw material handling and transportation, nor to pay for transporting some unneeded volatile or gaseous components such as the CO2, that are present in the raw materials used such as in the sodium carbonate.
SUMMARY OF THE INVENTION.
It is therefore a main object of the present invention, to provide a multifunctional single product for detergent formulations including most of the typical oxides normally included in the detergent formulations.
It is also a main object of the present invention, to provide a multifunctional single product for detergent formulations, as a single product performing al least some of the main functions in the detergent formulations such as builder, conditioner, filler, carrier and neutralizing agent, among others, which is soluble in water, and which is less expensive than the raw materials to be substituted.
It is another main object of the present invention, to provide a multifunctional single product for detergent formulations, of the above disclosed nature, which allows to control the relation of all the oxides, such as PZO~INa20/Si02, in a most wide range than by using only the respective raw materials.
It is yet another main object of the present invention, to provide a multifunctional single product for detergent formulations, of the above disclosed nature, as a single reacted product, with which the detergent. producer will have not to pay for multiple raw materials, handling and transportation thereof, nor to pay for transporting unneeded volatile or gaseous components that are an integral part of the raw materials presently used.
It is a further object of the present invention, to provide a process for producing a multifunctional single product for detergent formulations, by mixing and reacting a balanced mixture of primary raw materials or natural or partially treated minerals such as phosphoric rock, sodium sulfate ore, trona and silica sand, or intermediate products therefrom, into a furnace, to provide a powder or a glass, containing essential oxides for the detergent formulations.
It is still a further object of the present invention, to provide a process for producing a multifunctional single product for detergent formulations, including an annealing step for the product, in order to provide a desired chemical structure for the product.
These and other objects and advantages of the product and the process of the present invention will be apparent from the description of the invention, taken in connection with the following detailed description and specific examples thereof.
