Abstract: A non-tower process for continuously preparing granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the steps of (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, in a mixer, and (b) granulating the agglomerates in one or more fluidizing apparatus. The process can also comprise further step (a'), i.e., spraying finely atomized liquid onto the first agglomerates in a mixer, between step (a) and step (b).

Description: PROCESS FOR MAKING A DETERGENT COMPOSITION BY NON-TOWER PROCESS FIELD OF THE INVENTION The present invention generally relates to a non-tower process for producing a particulate detergent composition. More particularly, the invention is directed to a continuous process during which detergent agglomerates are produced by feeding a surfactant and coating materials into a series of mixers. The process produces a free flowing, detergent composition whose density can be adjusted for wide range of consumer needs, and which can be commercially sold. BACKGROUND OF THE INVENTION Recently, there has been considerable interest within the detergent industry for laundry detergents which are "compact" and therefore, have low dosage volumes. To facilitate production of these so-called low dosage detergents, many attempts have been made to produce high bulk density detergents, for example with a density of 600 g/1 or higher. The low dosage detergents are currently in high demand as they conserve resources and can be sold in small packages which are more convenient for consumers. However, the extent to which modern detergent products need to be "compact" in nature remains unsettled. In fact, many consumers, especially in developing countries, continue to prefer a higher dosage levels in their respective laundering operations. Generally, there are two primary types of processes by which detergent granules or powders can be prepared. The first type of process involves spray- drying an aqueous detergent slurry in a spray-drying tower to produce highly porous detergent granules (e.g., tower process for low density detergent compositions). In the second type of process, the various detergent components are dry mixed after which they are agglomerated with a binder such as a nonionic or anionic surfactant, to produce high density detergent compositions (e.g., agglomeration process for high density detergent compositions). In the above two processes, the important factors which govern the density of the resulting detergent granules are the shape, porosity and particle size distribution of said granules, the density of the various starting materials, the shape of the various starting materials, and their respective chemical composition. There have been many attempts in the art for providing processes which increase the density of detergent granules or powders. Particular attention has been given to densification of spray-dried granules by post tower treatment. For example, one attempt involves a batch process in which spray-dried or granulated detergent powders containing sodium tripolyphosphate and sodium sulfate are densified and spheronized in a Marumerizer®. This apparatus comprises a substantially horizontal, roughened, rotatable table positioned within and at the base of a substantially vertical, smooth walled cylinder. This process, however, is essentially a batch process and is therefore less suitable for the large scale production of detergent powders. More recently, other attempts have been made to provide continuous processes for increasing the density of "post- tower" or spray dried detergent granules. Typically, such processes require a first apparatus which pulverizes or grinds the granules and a second apparatus which increases the density of the pulverized granules by agglomeration. While these processes achieve the desired increase in density by treating or densifying "post tower" or spray dried granules, they are limited in their ability to go higher in surfactant active level without subsequent coating step, in addition, treating or densifying by "post tower" is not favourable in terms of economics (high capital cost) and complexity of operation. Moreover, all of the aforementioned processes are directed primarily for densifying or otherwise processing spray dried granules. Currently, the relative amounts and types of materials subjected to spray drying processes in the production of detergent granules has been limited. For example, it has been difficult to attain high levels of surfactant in the resulting detergent composition, a feature which facilitates production of detergents in a more efficient manner. Thus, it would be desirable to have a process by which detergent compositions can be produced without having the limitations imposed by conventional spray drying techniques. To that end, the art is also replete with disclosures of processes which entail agglomerating detergent compositions. For example, attempts have been made to agglomerate detergent builders by mixing zeolite and/or layered silicates in a mixer to form free flowing agglomerates. While such attempts suggest that their process can be used to produce detergent agglomerates, they do not provide a mechanism by which starting detergent materials in the form of pastes, liquids and dry materials can be effectively agglomerated into crisp, free flowing detergent agglomerates. Accordingly, there remains a need in the art to have an agglomeration (non-tower) process for continuously producing a detergent composition having high density delivered directly from starting detergent ingredients, and preferably the density can be achieved by adjusting the process condition. Also, there remains a need for such a process which is more efficient, flexible and economical to facilitate large-scale production of detergents (1) for flexibility in the ultimate density of the final composition, and (2) for flexibility in terms of incorporating several different kinds of detergent ingredients, especially detergent ingredients in the form of liquid, into the process.

These and other objects, features and attendant advantages of the present invention will become apparent to those skilled in the art from a reading of the following detailed description of the preferred embodiment and the appended claims. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention is directed to a process which produces free flowing, granular detergent agglomerates having a density of at least about 600 g/1. The process produces granular detergent agglomerates from an aqueous and/or non-aqueous surfactant which is then coated with fine powder having a diameter from 0.1 to 500 microns, in order to obtain low density granules. Process First Step (i) rstepfcil In the first step (i) of the process, one or more of aqueous and/or non- aqueous surfactant(s) which is/are in the form of powder, paste and/or liquid, and fine powder having a diameter from 0.1 to 500 microns, preferably from about 1 to about 100 microns are fed into a first mixer, so as to make agglomerates. (The definition of the surfactants and the fine powder are described in detail hereinafter.) Optionally, an internal recycle stream of powder having a diameter of about 0.1 to about 300 microns generated in the fluidizing apparatus (e.g., fluid bed dryer and/or fluid bed cooler) can be fed into the mixer in addition to the fine powder. The amount of such internal recycle stream of powder can be 0 to about 60 wt% of final product. Preferably, choppers which are attachable for the first mixer can be used to break up undesirable oversized agglomerates. Therefore, the process including the second with choppers is useful in order to obtain reduced amount of oversized agglomerates as final products, and such process is one preferred embodiment of the present invention. In another embodiment of the invention, the surfactant for the first step (i) can be initially fed into a mixer or pre-mixer (e.g. a conventional screw extruder or other similar mixer) prior to the above, after which the mixed detergent materials are fed into the first mixer as described herein for agglomeration. Generally speaking, preferably, the mean residence time of the first mixer is in range from about 0.5 to about 15 minutes and the energy per unit mass of the first mixer (energy condition) is in range from about 0.15 to about 7 kj/kg, more preferably, the mean residence time of the first mixer is from about 3 to about 6 minutes and the energy per unit mass of the first mixer (energy condition) is in range from about 0.15 to about 4kj/kg. The examples of the first mixer can be any types of mixer known to the skilled in the art, as long as the mixer can maintain the above mentioned condition for the first step. An Example can be Lόdige KM Mixer manufactured by the Lδdige company (Germany). As the result of the first step (i), the agglomerates (first agglomerates) are then obtained. The first agglomerates are then subjected to either (1) the second step, or (2) the first step (ii), followed by the second step. First Step (ii) TStep (a')1 The resultant from the first step (i) (i.e., the first agglomerates) is fed into a second mixer. The first agglomerates are fed into a second mixer, and then finely atomized liquid is sprayed on the agglomerates in the second mixer. Optionally, excessive fine powder formed in the first step (i) is added to the first step (ii). If the excessive fine powder is added to the first step (ii), spraying the finely atomized liquid is useful in order to bind the excessive fine powder onto the surface of agglomerates. About 0-10% , more preferably about 2-5% of powder detergent ingredients of the kind used in the first step (i) and/or other detergent ingredients can be added to the second mixer. Generally speaking, preferably, the mean residence time of the second mixer is in range from about 0.2 to about 5 seconds and tip speed of the mixer of the second mixer is in range from about 10 m/s to about 30 m/s, the energy per unit mass of the second mixer (energy condition) of the second mixer is in range from about 0.15 kj/kg to about 5 kj/kg, more preferably, the mean residence time of the second mixer is in range from about 0.2 to about 5 seconds and tip speed of the second mixer is in range from about 10 m/s to about 30 m/s, the energy per unit mass of the second mixer (energy condition) is in range from about 0.15 kj/kg to about 5 kj/kg, the most preferably, the mean residence time of the second mixer is in range from about 0.2 to about 5 seconds, tip speed of the second mixer is in range from about 15 m/s to about 26 m/s, the energy per unit mass of the second mixer (energy condition) is from about 0.2 kj/kg to about 3 kj/kg. The examples of the second mixer can be any types of mixer known to the skilled in the art, as long as the mixer can maintain the above mentioned condition for the first step (ii). An Example can be Flexomic Model manufactured by the Schugi company (Netherlands). As the result of the first step (ii), the second agglomerates are then obtained. Second Step r Step (b)] In the second step, the first agglomerates from the first step (i), or the second agglomerates from the first step (ii), are fed into a fluidized apparatus, such as fluidized bed, in order to enhance granulation for producing free flowing high density granules. The second step can proceed in one or more than one fluidized apparatus (e.g., combining different kinds of fluidized apparatus such as fluid bed dryer and fluid bed cooler). Optionally, about 0 to about 10% , more preferably about 2-5% of powder detergent materials of the kind used in the first step and/or other detergent ingredients can be added to the second step. Also, optionally, about 0 to about 20%, more preferably about 2 to about 10% of liquid detergent materials of the kind used in the first step (i), the first step (ii) and/or other detergent ingredients can be added to the step, for enhancing granulation and coating on the surface of the granules. Generally speaking, to achieve the density of at least about 600 g/l, preferably more than 650g/l, condition of a fluidized apparatus can be; Mean residence time : from about 1 to about 10 minutes Depth of unfluidized bed : from about 100 to about 300 mm Droplet spray size : not more than about 50 micron Spray height: from about 175 to about 250 mm Fluidizing velocity : from about 0.2 to about 1.4 m/s Bed temperature : from about 12 to about 100 °C, more preferably; Mean residence time : from about 2 to about 6 minutes Depth of unfluidized bed : from about 100 to about 250 mm Droplet spray size : less than about 50 micron Spray height: from about 175 to about 200 mm Fluidizing velocity : from about 0.3 to about 1.0 m/s Bed temperature : from about 12 to about 80 °C. If two different kinds of fluidized apparatus would be used, mean residence time of the second step in total can be from about 2 to about 20 minutes, more preferably, from about 2 to 12 minutes. A coating agent to improve flowability and/or minimize over agglomeration of the detergent composition can be added in one or more of the following locations of the instant process: (1) the coating agent can be added directly after fluid bed cooler or fluid bed dryer; (2) the coating agent may be added between fluid bed dryer and the fluid bed cooler; and/or (3) the coating agent may be added directly to fluid bed dryer. The coating agent is preferably selected from the group consisting of aluminosilicates, silicates, carbonates and mixtures thereof. The coating agent not only enhances the free flowability of the resulting detergent composition which is desirable by consumers in that it permits easy scooping for detergent during use, but also serves to control agglomeration by preventing or minimizing over agglomeration. As those skilled in the art are well aware, over agglomeration can lead to very undesirable flow properties and aesthetics of the final detergent product.

Other preferable examples of the aqueous or non-aqueous polymer solutions which can be used as the finely atomized liquid in the present invention are polymeric polycarboxylate dispersants which can be prepared by polymerizing or copolymerizing suitable unsaturated monomers, preferably in their acid form. Unsaturated monomeric acids that can be polymerized to form suitable polymeric polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polymeric polycarboxylates herein of monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than about 40% by weight of the polymer. Homo-polymeric polycarboxylates which have molecular weights above 4000, such as described next are preferred. Particularly suitable homo- polymeric polycarboxylates can be derived from acrylic acid.

Adjunct Detergent Ingredients The starting detergent material in the present process can include additional detergent ingredients and/or, any number of additional ingredients can be incorporated in the detergent composition during subsequent steps of the present process. These adjunct ingredients include other detergency builders, bleaches, bleach activators, suds boosters or suds suppressors, antitarnish and anticorrosion agents, soil suspending agents, soil release agents, germicides, pH adjusting agents, non-builder alkalinity sources, chelating agents, smectite clays, enzymes, enzyme-stabilizing agents and perfumes. See U.S. Patent 3,936,537, issued February 3, 1976 to Baskerville, Jr. et al., incorporated herein by reference. Other builders can be generally selected from the various water-soluble, alkali metal, ammonium or substituted ammonium phosphates, polyphosphates, phosphonates, polyphosphonates, carbonates, borates, polyhydroxy sulfonates, polyacetates, carboxylates, and polycarboxylates. Preferred are the alkali metal, especially sodium, salts of the above. Preferred for use herein are the phosphates, carbonates, C-ιo-18 fatty acids, polycarboxylates, and mixtures thereof. More preferred are sodium tripolyphosphate, tetrasodium pyrophosphate, citrate, tartrate mono- and di-succinates, and mixtures thereof (see below). In comparison with amorphous sodium silicates, crystalline layered sodium silicates exhibit a clearly increased calcium and magnesium ion exchange capacity. In addition, the layered sodium silicates prefer magnesium ions over calcium ions, a feature necessary to insure that substantially all of the "hardness" is removed from the wash water. These crystalline layered sodium silicates, however, are generally more expensive than amorphous silicates as well as other builders. Accordingly, in order to provide an economically feasible laundry detergent, the proportion of crystalline layered sodium silicates used must be determined judiciously. Such crystalline layered sodium silicates are discussed in Corkill et al, U.S. Patent No. 4,605,509, previously incorporated herein by reference. Specific examples of inorganic phosphate builders are sodium and potassium tripolyphosphate, pyrophosphate, polymeric metaphosphate having a degree of polymerization of from about 6 to 21 , and orthophosphates. Examples of polyphosphonate builders are the sodium and potassium salts of ethylene diphosphonic acid, the sodium and potassium salts of ethane 1-hydroxy-1 , 1-diphosphonic acid and the sodium and potassium salts of ethane, 1 ,1 ,2-triphosphonic acid. Other phosphorus builder compounds are disclosed in U.S. Patents 3,159,581 ; 3,213,030; 3,422,021 ; 3,422,137; 3,400,176 and 3,400,148, all of which are incorporated herein by reference. Examples of nonphosphorus, inorganic builders are tetraborate decahydrate and silicates having a weight ratio of S1O2 to alkali metal oxide of from about 0.5 to about 4.0, preferably from about 1.0 to about 2.4. Water-soluble, nonphosphorus organic builders useful herein include the various alkali metal, ammonium and substituted ammonium polyacetates, carboxylates, polycarboxylates and polyhydroxy sulfonates. Examples of polyacetate and polycarboxylate builders are the sodium, potassium, lithium, ammonium and substituted ammonium salts of ethylene diamine tetraacetic acid, nitrilotriacetic acid, oxydisuccinic acid, mellitic acid, benzene polycarboxylic acids, and citric acid. Polymeric polycarboxylate builders are set forth in U.S. Patent 3,308,067, Diehl, issued March 7, 1967, the disclosure of which is incorporated herein by reference. Such materials include the water-soluble salts of homo- and copolymers of aliphatic carboxylic acids such as maleic acid, itaconic acid, mesaconic acid, fumaric acid, aconitic acid, citraconic acid and methylene malonic acid. Some of these materials are useful as the water-soluble anionic polymer as hereinafter described, but only if in intimate admixture with the non-soap anionic surfactant. Other suitable polycarboxylates for use herein are the polyacetal carboxylates described in U.S. Patent 4,144,226, issued March 13, 1979 to Crutchfield et al, and U.S. Patent 4,246,495, issued March 27, 1979 to Crutchfield et al, both of which are incorporated herein by reference. These polyacetal carboxylates can be prepared by bringing together under polymerization condition an ester of glyoxylic acid and a polymerization initiator. The resulting polyacetal carboxylate ester is then attached to chemically stable end groups to stabilize the polyacetal carboxylate against rapid depolymerization in alkaline solution, converted to the corresponding salt, and added to a detergent composition. Particularly preferred polycarboxylate builders are the ether carboxylate builder compositions comprising a combination of tartrate monosuccinate and tartrate disuccinate described in U.S. Patent 4,663,071 , Bush et al., issued May 5, 1987, the disclosure of which is incorporated herein by reference.

Chelating agents are also described in U.S. Patent 4,663,071, Bush et al., from Column 17, line 54 through Column 18, line 68, incorporated herein by reference. Suds modifiers are also optional ingredients and are described in U.S. Patents 3,933,672, issued January 20, 1976 to Bartoletta et al., and 4,136,045, issued January 23, 1979 to Gault et al., both incorporated herein by reference.

Optional Process Steps Optionally, the process can comprise the step of spraying an additional binder in one or more than one of the first, second and/or the third mixers for the present invention. A binder is added for purposes of enhancing agglomeration by providing a "binding" or "sticking" agent for the detergent components. The binder is preferably selected from the group consisting of water, anionic surfactants, nonionic surfactants, liquid silicates, polyethylene glycol, polyvinyl pyrrolidone polyacrylates, citric acid and mixtures thereof. Other suitable binder materials including those listed herein are described in Beerse et al, U.S. Patent No. 5,108,646 (Procter & Gamble Co.), the disclosure of which is incorporated herein by reference. Other optional steps contemplated by the present process include screening the oversized detergent agglomerates in a screening apparatus which can take a variety of forms including but not limited to conventional screens chosen for the desired particle size of the finished detergent product. Other optional steps include conditioning of the detergent agglomerates by subjecting the agglomerates to additional drying by way of apparatus discussed previously. Another optional step of the instant process entails finishing the resulting detergent agglomerates by a variety of processes including spraying and/or admixing other conventional detergent ingredients. For example, the finishing step encompasses spraying perfumes, brighteners and enzymes onto the finished agglomerates to provide a more complete detergent composition. Such techniques and ingredients are well known in the art. Another optional step in the process involves surfactant paste structuring process, e.g., hardening an aqueous anionic surfactant paste by incorporating a paste-hardening material by using an extruder, prior to the process of the present invention.
