Description

The only multifunction product for detergent formulations

A. Technical Field

The present invention relates to a detergent formulation multifunctional product, and more particularly to a single product in the form of a powder or waterglass that is soluble in water and acts inter alia as builder, conditioner, filler, and carrier (s). carrier) in detergents and in its manufacturing process.

B. BACKGROUND OF THE INVENTION

The most common oxides needed to make detergents are: phosphorus pentoxide (P ₂ O ₅ ) sodium oxide (Na ₂ O), silicon dioxide, as well as other additives such as boron oxide and others.

These oxides are normally supplied through a variety of raw materials or chemical compounds such as sodium carbonate (Na ₂ CO ₃ ⁱⁿ ), pentasodium tripolyphosphate, sodium sulfite (Na ₂ SO ₄ ), sodium silicate (xNa ₂ O.ySiO ₂ ) and sodium borate ( Na ₂ B ₄ O ₇ ).

It is well known that each detergent manufacturer has its own formulas, but each manufacturer normally buys and uses the typical chemical compounds mentioned above as raw materials. .

In investigating the tasks and functions performed by each of these compounds, the Applicant has found that each of these compounds performs a certain role and acts as a builder in detergents, as a conditioner, as filler, as a carrier ( a catalyst (carrier), as a neutralizing agent, etc., and / or in the manufacturing process.

Considering that the high number of different raw materials to be used for each preparation (in order to fulfill its respective role),

the cost of producing detergents (in fact, most detergent manufacturers have to purchase at least 5 to 8 or more different raw materials or reagents to define their formulas), the applicant has set itself the goal of developing a single new multifunctional product for detergents most typical oxides that are normally contained in a detergent formula that performs at least some of the main functions it could perform as well as the original water-soluble chemical reagents and which could reduce raw material costs.

To this end, the Applicant has observed that pentasodium tripolyphosphate, a raw material normally used in detergent formulations as a source of phosphorus pentoxide (P ₂ O ₅ ), is produced by reacting phosphoric acid with sodium carbonate; whereas, in turn, phosphoric acid is obtained by reacting ground calcium orthophosphate with sulfuric acid, which is filtered to eliminate impurities, which in turn is nothing more than silicon dioxide, which is also part of the detergent formula; and that sodium carbonate is normally obtained by a certain process of treatment of tronium ore (trisodium carbonate-bicarbonate dihydrate), in which impurities are deposited, which is nothing more than silicon dioxide, which is also part of the detergent formulations.

Therefore, the applicant concludes that if mixtures of impurities are also substances present in detergent formulations and that the processes carried out to eliminate them also increase the cost of raw materials and hence the cost of the final detergents, they are not needed and calcium orthophosphate or at least phosphoric acid can be used on the basis of a single partial treatment (such as treatment with acid or base, as well as grinding, screening and sieving) to produce a product,

9 9 * 9 9999 • 99 99 9 which could be used as a P ₂ O ₅ source and as a partial SiO ₂ source in detergent formulations.

Na ₂ O is supplied via sodium carbonate, which is obtained by treating trone (trisodium carbonate bicarbonate dihydrate) by a process that includes grinding, dissolving, filtering to eliminate compounds that are considered impurities (which are also used in detergent formulations) and crystallization to obtain sodium carbonate. Here again, the applicant concludes that it may be unnecessary to process the mineral in order to avoid something that is also needed in detergent formulations and the tron (trisodium carbonate-bicarbonate dihydrate) could be used directly, in a simple grinding step, reduced costs to produce a single product that could be tailored to the needs of the detergent formulations.

SiO ₂ is supplied to sodium silicate, which is obtained by the reaction of silica sand and sodium carbonate in the furnace. The multifunctional product developed by the Applicant will provide the silica required for detergent formulations.

In other words, by using a single balanced mixture of raw materials or minerals including oxide sources for detergent formulations and by reacting these oxides in the furnace, it is possible to provide a single multifunctional product for any detergent formulation.

With such a product, the detergent manufacturer will not have to purchase 5 or 8 different ingredients for the recipe, but a single product that will be less expensive as it will not include the cost of the purification processes that each raw material requires. creation of each of the existing raw materials.

This product will provide the need for oxides for the detergent formulation and manufacturing process and will perform basic tasks and functions such as builder, conditioner, filler and carrier, neutralizer, etc. in detergent formulations and in the process of making the detergent.

Therefore, the applicant has found that by mixing natural or partially treated (ground or crushed) raw materials or minerals containing calcium orthophosphate, tron (trisodium carbonate bicarbonate dihydrate), silica sand, sodium sulfate and / or other intermediates such as phosphoric acid and sodium bicarbonate, in proportions according to the needs of a particular detergent formulation and their introduction into the furnace to effect their reaction, a single product is obtained in the form of: a powder when the furnace is operated at a lower reaction temperature without melting; as water glass if the furnace is operated at reaction and melting temperatures; or as a liquid if the product is dissolved after it has been obtained as a powder or as a water glass.

This product can also be used in detergent manufacturing processes, instead of all raw materials used in traditional processes to accomplish each of the roles or functions such as filler, catalytic agent, filler and others.

The product obtained is thus soluble in water and will perform basic tasks and functions such as filler, conditioner, filler, catalytic agent, etc. in the detergent formulations and in its manufacturing process and will be less expensive than the normally used raw materials.

Furthermore, it is also known that detergent manufacturers change their manufacturing technology to produce detergents in the roasting and agglomeration process. In both cases they need the same type of raw materials, but they need solid and liquid

raw materials such as pentasodium tripolyphosphate and sodium silicate. The Applicant has found that a further advantage that detergent manufacturers can obtain from the product of the present invention is that it allows to control the ratio of all oxides such as P ₂ O ₅ / Na ₂ O / SiO ₂ to a wider range than using only the appropriate raw materials and supplying a single solid or liquid product.

And last but not least, for the product of the present invention, detergent manufacturers do not have to pay for handling and transporting many kinds of raw materials, nor will they have to pay for transporting some unnecessary volatile or gaseous components such as CO ₂ , which is present in the raw materials used, as in sodium carbonate.

SUMMARY OF THE INVENTION

It is therefore a main object of the present invention to provide a multifunctional detergent formulation product that will contain most of the typical oxides normally included in detergent formulations.

The main object of the present invention is also to provide a single multifunctional product for detergent formulations, as the only product that performs at least some of the major functions of detergent formulations such as builder, conditioner, filler, catalytic a carrier and a neutralizing agent which is water-soluble and less expensive than the raw materials it will replace.

It is a further main object of the present invention to provide a single multifunctional detergent formulation product which is of the above nature and which allows to control the ratio of all these oxides such as

P ₂ O ₅ / Na ₂ O / SiO ₂ in a wider range than using only the corresponding raw materials.

Yet another main object of the present invention is to provide a single multifunctional detergent formulation product of the nature discussed above, as the only reacted product in which the detergent manufacturer will not have to pay for, handle, transport or transport a variety of raw materials have to pay for the transport of unnecessary volatile or gaseous constituents, which form an integral part of the raw materials currently used.

An additional object of the present invention is to provide a process for manufacturing a single multifunctional product for detergent formulations, comprising mixing and reacting a balanced mixture of natural or partially treated raw materials or minerals such as calcium orthophosphate, sodium sulfate, trona (trisodium carbonate bicarbonate dihydrate) and quartz sand. in an oven to obtain a powder or waterglass containing the basic oxides for the detergent formulations.

An additional object of the present invention is to provide a process for manufacturing a single multifunctional product for detergent formulations, which comprises an annealing step for the product to impart the desired chemical structure to the product.

These and other objects and advantages of this product and process of the invention will be apparent from the description of the invention, which will be performed in conjunction with the following detailed description and specific examples of the invention.

DESCRIPTION OF THE SPECIFIC IMPLEMENTATIONS OF THE INVENTION

The invention will now be described first in connection with the process of manufacturing a single multifunctional product for detergent formulations and then in relation to the preferred products of the invention.

The process for producing a single multifunctional product for the detergent formulations of the invention comprises the following:

Mix a balanced mixture of ground or crushed raw materials or natural or partially processed minerals, including calcium orthophosphate, sodium sulphate ore, tron (trisodium carbonate carbonate dihydrate) and quartz sand or intermediates thereof; and reacting the mixture in an oven to obtain a powder or waterglass containing the basic oxides for the detergent formulations.

The reactions are allowed to proceed either below the melting point of the mixture to obtain a powder, or at the reaction temperature and melting point of the mixture to obtain waterglass.

If the product is to be in liquid form, depending on the detergent production process, the process involves dissolving the powder or glass product in a solvent to obtain a liquid product that includes most of the typical oxides that are normally contained in detergent formulations.

Further, if it is desired to provide a specific structure for a particular product, for a specific purpose of the detergent manufacturer, a final annealing step of the product may be incorporated into the process.

In accordance with the invention comprises a single vyreagovaný product basic oxides, such as phosphorus pentoxide (P ₂ O _5), sodium oxide (Na ₂ O), silica _(SiO2), balanced in accordance with the specific recipes detergent which is soluble in water and acts as a builder, conditioner, filler, carrier

(carrier catalyst) and a neutralizing agent in the product and in the process for producing the detergent.

As is the case with sodium sulphate for the manufacture of waterglass products, where only a limited maximum amount of sodium sulphate has been set, above which undesirable phase separation occurs, resulting in two immiscible liquids, since no one has yet foreseen or suggested the use of a diagram phase to determine its balanced optimal amount, in a single product of the present invention, no one has envisaged or remotely proposed to let natural or partially processed minerals act to obtain a single product containing both the necessary base oxides for detergent formulations and other components which are also included in the detergent formulations.

The final oxide content of the product of the invention will depend on the type and content of oxide in the detergent formulation, which is normally kept secret by detergent manufacturers.

Accordingly, in order to enable those of ordinary skill in the art to practice the above-described invention, the following examples, which have been selected according to the following appended figures, are provided for information only to demonstrate the practicability of the invention without considering that the end product be used for a specific detergent composition.
