Description
I COMPOSITION BASED ON A SUBSTANTIALLY OR COMPLETELY HYDROSOLUBLE MINERAL SALT, A FORMULATION CONTAINING SAID SALT, AND PREPARATION THEREOF The present invention relates to a composition in the form of solid particles that are 5 substantially or completely hydrosoluble, comprising a mineral salt crystallising with at least one molecule of water, and a binder. The composition can be obtained by a drying operation eliminating at least a portion of the water of crystallisation of said salt. The invention also relates to a formulation comprising at least one active ingredient absorbed on the above composition and to a process for preparing said formulation. 0 Many technical fields require the preparation of flowable powders based on liquid or dissolved active ingredients. Such possibilities include that consisting of forming a grain into which the active ingredient is absorbed. One of the problems to be overcome concerns the absorption capacity of the grain. This latter must be as high as possible in order to obtain the highest possible concentration of active 5 ingredient after absorption. A further difficulty, which is a consequence of a high absorption capacity, is the wear resistance of the grain. The higher the absorption capacity, the higher the porosity, and the lower the wear resistance, which can produce difficulties when storing the grain alone, for example, and sometimes when storing the complete formulation. 20 In the detergent field, preparation processes comprising two steps are known, the first consisting of preparing the grain alone, and the second of spraying the active ingredient onto it, which active ingredient is usually a non ionic surfactant. The grain is obtained by spraying a mixture comprising a silicate or phosphate type salt and possibly other additives such as anti-redepositing agents. The active ingredient, which may 25 also contain additives, is then sprayed onto the grains obtained.
L While advantages exist with such a process, there still remains the fact that the absorption capacity of the granule remains somewhat low. The prior art does contain processes for preparing highly adsorbent compounds, such as sodium carbonate. The processes start from sodium carbonate decahydrate, which undergoes a 5 highly controlled heat treatment, the aim of which is to eliminate the 10 water molecules present, creating substantial porosity in the particles. However, the particle size does not exceed an average of 10 pm. As a result, while the absorption capacity is very high, such particles are not always desirable, as they require precautions to be taken due to their pulverulent nature. The present invention proposes a composition that can serve as a matrix for an active o ingredient intended to be absorbed therein, which composition is completely or substantially hydrosoluble, highly adsorbent and non pulverulent. It should be noted that the term "substantially" as used in the present invention means more than 50% of said composition can be dissolved in water, more particular at least 80%, preferably at least 90%. 5 In a first aspect, the invention provides a composition, in the form of solid particles that are substantially or completely hydrosoluble, wherein the absorption capacity for at least one active ingredient can be as high as 50% by weight, corresponding to the weight ratio of the active ingredient to the sum of the weight of the composition and the active ingredient; said composition being capable of being obtained from at least one mineral salt crystallising with at !0 least one molecule of water, at least one polymeric organic binder in an amount of less than 30% by weight of the composition, optionally at least one surfactant, optionally at least one filler, said composition being capable of being obtained by drying to eliminate at least a portion of the water of crystallisation. In a second aspect, the invention provides a process for preparing said composition, in 5 which at least the water of crystallisation present in a mixture comprising at least one said mineral salt, at least one polymeric organic binder, optionally at least one surfactant, optionally at least one filler, and water that is at least in the form of the water of crystallisation is partially or completely eliminated. In a further aspect, the invention concerns a formulation comprising at least one active ingredient absorbed on the composition of the invention. 5 Finally, in a final aspect, the invention concerns the preparation of said formulation; in which process the active ingredient is sprayed or impregnated, in the form of a liquid, onto the composition of the invention. As mentioned above, the composition of the invention has the advantage of having a very high absorption capacity. It is possible to absorb on the composition a quantity of active o ingredient that represents the weight of the composition. In other words, the composition of the invention has an absorption that can be as high as 50% (weight ratio of the active material to the sum of the weight of the composition and the active ingredient). The absorption capacity is measured with respect to Rhodasurf ID 79, which is a non ionic surfactant (isodecyl alcohol containing 7 ethylene oxide moieties, sold by Rhodia Chimie). 5 The test consists of bringing the composition into contact with the surfactant, at ambient temperature, progressively and with stirring, until the mixture has a sticky appearance (the solid mixture not longer flows - non free-flowing). The quantity of surfactant added is then determined. Because of its pH, the composition of the invention has the advantage of being !o compatible with use in many fields of application as varied as the detergent industry, the food industry, the pharmaceutical industry and the agrochemicals industry. The composition of the invention is constituted by non pulverulent porous particles the size of which is sufficient not to cause handling problems. Further, the wear resistance of the particles of the composition is improved, which has 5 clear advantages as regards storing and handling the composition.
The composition of the invention can be used to obtain solid formulations, although the active ingredient can be liquid, molten or dissolved. The composition of the invention has the advantage of being capable of being mixed in the same packaging with substances that would have been incompatible in a liquid mixture (for 5 example, if the substances can react together chemically). Further, the composition of the invention can be adapted as a function of the active ingredient for which it acts as a support. The composition of the invention can advantageously be used for pH-sensitive active ingredients. A supplemental advantageous characteristic of the composition of the invention is that it o contributes to facilitating the use of the final formulation containing it. The composition of the invention endows that formulation with dissolution properties that are more or less rapid and above all, can be adjusted. The hardness of the granule (wear resistance), its absorption capacity, its pH, can also be adjusted as a function of the final use of the formulations containing it. This constitutes an 5 important characteristic of the composition of the invention. Finally, the process for preparing the composition of the invention is simple and can produce a variety of particle shapes. Further characteristics and advantages of the present invention will become clear from the following description and examples. z0 As indicated above, the composition of the invention comprises a mineral salt crystallising with at least one molecule of water. More particularly, the mineral salt is selected from alkali metal phosphates, alkali metal carbonates, alkali metal or aluminium sulphates, alkali metal borates, aluminium salts, magnesium chloride or mixtures thereof.
Particular alkali metal phosphates that are suitable for use in the invention are the pyrophosphate, tripolyphosphate, mono-, di- or tri-sodium phosphate, hexametaphosphate, or mixtures thereof. Preferably, the composition of the invention comprises, as the mineral salt, at least one 5 salt selected from phosphates, in particular those mentioned above, and from alkali metal carbonates, more particular sodium. Preferably, the mineral salts used to prepare the composition of the invention do not contain tripolyphosphate alone. In an advantageous embodiment, the salts employed contain no tripolyphosphate, either alone or combined with one or more other salts. o The quantity of mineral salt represents 50% to less than 100% by weight of the composition. In a particular embodiment of the invention, the quantity of mineral salt is in the range 70% to less than 100% by weight with respect to the composition. Preferably, the quantity of mineral salt is in the range 85% to less than 100% by weight with respect to the composition. The composition of the invention also comprises at least one polymeric organic binder. 5 Compounds that can be cited that can be used as a binder, either alone or in combination, are monosaccharides, oligosaccharides, natural polymers of the polysaccharide type of animal, vegetable, bacterial origin, synthetic polymers of the polyalkyleneglycol type, polyvinyl alcohol, (meth)acrylic acid polymers or a copolymer of (meth)acrylic acid and isobutylene or diisobutylene, polyacrylic acids and their salts, copolymers of maleic anhydride (or acid) and zo isobutylene or diisobutylene, and their salts, and mixtures thereof Lactose and saccharose, used alone or as a mixture, represent possible examples of binders selected from monosaccharides and oligosaccharides. Natural polymers of the polysaccharide type of animal, vegetable, bacterial origin that can be cited by way of non-limiting example are xanthan gum, guar gum and its derivatives 25 (such as hydroxypropyl guar), polydextroses, and combinations thereof.
Suitable synthetic polymers, used alone or as a mixture, include polyethylene glycols, polypropylene glycols, polybutylene glycols, copolymers of polyethylene and polypropylene glycols, polyvinyl alcohol, (meth)acrylic acid polymers or copolymers of (meth)acrylic acid and isobutylene or diisobutylene, and their salts. 5 Particularly suitable polymers representing a preferred embodiment of the invention are acrylic acid polymers such as Geropon* HB, and copolymers of maleic anhydride (or acid) and diisobutylene. The copolymers can be in the acid form or in the form of an alkali metal or ammonium salt of the N(R) 4 * type, where R, which may be identical or different, represents hydrogen atoms 0 or C-C 4 hydrocarbon radicals. Preferably, the copolymer is in the form of the sodium salt. These copolymers are known compounds and are sold under the trade name GEROPON* T36 (Rhodia). More particularly, the quantity of binder is in the range 0 (excluded) to 30% by weight of the composition of the invention. In a particular embodiment of the invention, the quantity of 5 binder is in the range 0 (excluded) to 15% by weight with respect to the composition weight. However, in a highly preferred variation of the invention, the amount of binder is in the range 0.5% to 15% by weight with respect to the composition. It should be noted that if the composition of the invention contains only mineral salt and polymeric binder, the respective quantities of these compounds are such that the ensemble o represents 100% by weight. In one embodiment of the invention, the weight ratio between the mineral salt and the binder is in the range 99.5/0.5 to 60/40. More particularly, this weight ratio is in the range 99.5/0.5 to 70/30, preferably in the range 99.5/0.5 to 85/15. The composition of the invention can also contain at least one surfactant, if required.
Without wishing to be limited to a particular theory, the surfactant may play a double role when present, namely that of optimising wetting of the mineral salt and binder, and that of optimising dispersion of the active ingredient during its use. Any surfactant may be suitable, provided that it is compatible with the active ingredient. 5 Anionic, non-ionic, cationic, zwitterionic or amphoteric surfactants can be used. Examples of anionic surfactants that can be cited are: " polymers derived from lignin, such as sodium or calcium lignosulphonates; e alkylester sulphonates with formula R-CH(SO 3 M)-COOR', where R represents a C 8 C 20 alkyl radical, preferably C 10

The above surfactants can be used alone or as a mixture. More particularly, the quantity of surfactant is in the range 0 to 15% by weight with respect to the composition weight. More particularly still, it is in the range 0 to 5% by weight with respect to the composition weight. o The composition of the invention can optionally also contain at least one filler. Examples of fillers that can be used in the composition of the invention that can be cited are diatomaceous earths, clays such as bentonite, kaolin, attapulgite, zeolites; calcium carbonate, talc, mica, precipitated silica, alkali or alkaline-earth metal silicates, perlite, charcoal, lignite. These compounds can be present alone or as a mixture. 5 The quantity of feed is preferably such that the composition remains substantially or completely hydrosoluble.
1U More particularly, the quantity of feed in the composition represents 0 to 50% by weight with respect to the composition weight. In a particular embodiment of the invention, the quantity of feed represents 0 to 30% by weight, preferably 0 to 10% by weight with respect to the composition weight. In a more preferable embodiment of the invention, no filler is used. 5 The sum of all of the compounds cited above (mineral salt, binder, surfactant, filler) represents 100% of the composition weight. The process for preparing the composition of the invention will now be explained in more detail. As mentioned above, the process for preparing said composition consists in partially or o completely eliminating at least the water of crystallisation present in a mixture comprising at least one said mineral salt, at least one polymeric organic binder, optionally at least one surfactant, optionally at least one filler, and water that is at least in the form of the water of crystallisation. This drying step, during which the water, which is present at least in the form of water of 5 crystallisation, is eliminated, can adjust the absorption capacity of the granulate, such that at least the water of crystallisation of the mineral salt is eliminated. It should be noted that the drying operation can also eliminate all or part, preferably all, of the water that can be supplied when producing the mixture to be dried, in addition to the water of crystallisation. The drying operation will be described below. 0 This drying operation can advantageously be carried out in an oven, preferably in a fluidised bed. Drying is advantageously carried out in air at atmospheric pressure or under reduced pressure. The drying temperature depends on the nature of the compounds constituting the 5 composition of the invention. Further, it has to be sufficiently high to remove the water of crystallisation of the mineral salt.
11 A non limiting example of the temperature range is in the range 60*C to 150*C, preferably in the range 70*C to 120*C. The drying operation takes place on a mixture that can be obtained in accordance with several advantageous variations. 5 In a first variation, said drying is carried out on a mixture obtained as follows: * mixing at least one mineral salt in its anhydrous or partially hydrated form in the presence of at least one binder, optionally in the presence of at least one surfactant, optionally in the presence of at least one filler, with the quantity of water that is necessary and sufficient for complete hydration of said mineral salt; o * granulating the resulting mixture, more particularly using an aqueous solution. The term "partially hydrated" means a mineral salt with a degree of hydration of less than 80%. In this first variation, the mixture passes through an intermediate pasty condition. During This operation involves the steps of dissolving the salt (pasty medium) then salt hydration (re 5 appearance of powder). This intermediate phase can advantageously contribute to improving homogenisation of the mixture. The operation of adding water in a quantity sufficient and necessary to completely hydrate the mineral salt is preferably carried out in a shear mixer, in particular a turbosphere, Henry grinder, Stephan mixer or L6dige mixer. 0 The water may or may not be added progressively. It should be noted that it is preferable to use an apparatus that can remove the heat released on hydration. The granulation step is carried out in a conventional manner, (pan granulation, extrusion). The mixture in the form of particles is brought into contact with the granulation water. 5 Preferably, the granulation step is carried out in the presence of a quantity of water that can produce a mixture with a viscosity that is suitable for forming.
This amount of water clearly depends on the nature of the mineral salt or salts selected and the nature of the equipment used. It can readily be determined by the skilled person. However, by way of example, the quantity of water of granulation can be between 10% and 20% by weight with respect to the composition weight for agglomeration granulation. 5 Granulation is carried out in any suitable apparatus. It should be noted that the scope of the present invention encompasses adding a larger quantity of water then forming the product by extrusion, prior to drying. In a second variation of the preparation of the mixture for drying, at least one mineral salt in the substantially hydrated form is granulated in the presence of at least one binder, optionally 0 in the presence of at least one surfactant, optionally in the presence of at least one filler, and in the presence of water of granulation. The term "substantially hydrated" means that the degree of hydration of the mineral salt is 80% or more. Granulation takes place in a conventional manner (pan granulation, extrusion). 5 In particular, it can be carried out in a grinder/mixer or in any type of apparatus that can produce a homogeneous mixture, more particularly a homogeneous powder mixture. The amount of water of granulation employed (except for the water of crystallisation, if necessary) is preferably such that a mixture is obtained with a viscosity that is suitable for forming. This amount of water clearly depends on the nature of the mineral salt or salts selected, o and the equipment used and can readily be determined by the skilled person. By way of illustration, the quantity of water of granulation (with the exception of water of crystallisation) is between 10% and 20% by weight with respect to the composition weight for agglomeration granulation. One advantageous embodiment of this variation consists in adding the binder with the 5 water of granulation.
It should be noted that the scope of the present invention encompasses adding a larger quantity of water, then forming the product by extrusion, prior to drying. The third variation for preparing the mixture intended to be dried consists of carrying out the following steps: 5 * mixing at least one mineral salt in the presence of at least one binder, optionally in the presence of at least one surfactant and optionally in the presence of at least one filler, with the quantity of water necessary to produce a solution and/or a dispersion; " drying the solution and/or dispersion; e granulating the resulting dried mixture. 0 The salt employed can be in the partially or completely anhydrous or hydrated form. In this variation, the constituent elements of the composition are in a dissolved and/or dispersed state. It should be noted that since the composition of the invention is substantially hydrosoluble, within the context of the present invention, a solution is substantially obtained. The amount of water added can vary within wide limits the instant the mixture is 5 obtained in the form of a solution and/or dispersion. As an example, the amount of water added (or water of crystallisation) is in the range 20% to 60% by weight of water with respect to the weight of the composition in the dry state. Once the solution/dispersion has been produced, it is dried. Drying is not intended to eliminate the water of crystallisation, only the water supplied to produce the solution/dispersion. 0 This drying step can be carried out using known techniques. Advantageously, drying is carried out using atomisers in which the mixture is sprayed into a hot atmosphere (spray drying). Atomising can be carried out using any known spray means, for example a spray nozzle of the rose or other type. It is also possible to use turbine spray apparatus. The standard text by MASTERS entitled "SPRAY DRYING" (second edition, 5 1976, George Godwin, London) should be referred to regarding the various spray techniques that can be employed in the presence process.
1't It should be noted that it is also possible to carry out the spray drying operation using a "flash" reactor, for example of the type described in French patent applications FR-A-2 257 326, FR-A-2 419 754 and FR-A-2 431 321. In this case, the treatment gases (hot gases) move in a helical motion flowing in a vortex tube. The mixture to be dried is injected along a trajectory 5 that is coincident with the axis of symmetry of the helical trajectories of said gases, allowing the movement of the gas to be transferred perfectly to the mixture to be treated. The gases then carry out a double function: atomisation, i.e., transformation into fine particles, of the initial mixture, and drying the fine particles obtained. Further, the very short residence time (generally less than about 1/10 of a second) of the particles in the reactor has the advantage, inter alia, of o limiting any risks of overheating as a result of too long a contact with the hot gases. The flash reactor cited above is shown in Figure 1 of French patent application FR-A-2 431 321. The temperature of this drying step is such that it does not degrade the constituent elements of the composition. At the end of the drying step, solid particles are obtained that are granulated. 5 The granulation step is carried out conventionally (pan granulation, extrusion) by bringing the mixture, in the form of particles, into contact with the water of granulation. Reference should be made with regard to this step to the description of the preceding variations. It should be noted that it is possible to form the product by carrying out spray 0 granulation. In this case, it is more appropriate to carry out this third variation, granulation being carried out simultaneously with spray drying. It should also be noted that the drying step (in other words, elimination of the molecules of water of crystallisation from the mineral salt) can be carried out simultaneously in the spray dryer. If necessary, it may be advantageous to sieve the composition obtained after drying, to 5 obtain the desired grain size.
In a further aspect, the invention provides a formulation comprising at least one active ingredient absorbed on the composition of the invention. The above description relating to the composition of the invention and its preparation is applicable in this case and will therefore not be repeated here. 5 Any active ingredient is suitable provided that it is in the anhydrous form or comprises a quantity of water that is insufficient to dissolve the composition of the invention. The active ingredients can be in the liquid form at the temperature of processing or use, provided that the melting point of the active ingredient remains lower than that of the composition; they are in the dispersed/dissolved form in a suitable dispersant/solvent. o These active ingredients can also be formulated. They may be combined with other compounds such as surfactants, fillers, or additives that are conventional in the field in question (anti-foaming agents, etc). More particularly, said formulation can comprise at least one active ingredient for use in the fields of detergents, cosmetics, the food industry, the plant protection industry or the 5 construction materials industry. The surfactants having these characteristics and selected, for example, from those listed above above, can be employed as an active ingredient, for use in the fields of detergents, cosmetics, etc.. Preferably, they are non-ionic surfactants. o It is also possible to cite silicone substances in the form of oils, emulsions or compounds, also perfumes and colorants. In a further possibility, the formulation can comprise at least one active ingredient that can be used in the food industry.

It is also possible to use sucroesters (esters of food quality fatty acids and saccharose) and 5 sucroglycerides, which are the products obtained by transesterification using saccharose of synthesised triglycerides or, preferably, natural triglycerides. Of the sucroglycerides, those from palm oil, lard, coprah oil, tallow, rapeseed oil or castor oil can be used. One method for preparing sucroglycerides is described in French patent application FR-A-2 463 512. Esters of food quality fatty acids can be used; also esters of polypropylene glycol and food quality fatty 0 acids (monoesters or as a mixture with diesters); polyethylene glycol ricinoleate; esters of polyethylene glycol and fatty acids derived from oils, such as soya oil; fatty acid esters of glycerol and polyethylene glycol, such as fatty acids from tallow; ethers of polyglycerol and alcohols obtained by reducing oleic and palmitic acids; and partial esters of fatty acid polyglycerol from polycondensed castor oil. Advantageously, polysorbates are used. 5 In a further possibility, the formulation can comprise at least one active ingredient for use in the pharmaceutical field, such as a virus or enzymes.
I/ The formulation comprising the active ingredient can be obtained by spraying or impregnating said active ingredient, optionally in the presence of a dispersing agent/solvent, onto the composition of the invention. It should be noted, and this represents a supplemental advantage of the composition of 5 the invention, that this absorption step can be carried out directly after preparing the composition, or after storing the composition. Absorption is thus carried out in conventional manner by spraying, sprinkling or impregnating the active ingredient onto the composition of the invention. The active ingredient is in the form of a liquid, in the dissolved form, or in the molten 0 state. If the operation has taken place in the presence of a solvent, the resulting granulate is then dried. It should be noted that the scope of the present invention also encompasses using a formulation of the invention, i.e., comprising the composition and at least one active ingredient, 5 as an additive (adjuvant) to a more complex formulation. In this case, when preparing the complex formulation, using conventional means, it is sufficient to mix the formulation of the invention (comprising the composition and at least one active ingredient) with other constituent elements of the more complex formulation. It is also possible to prepare the formulation of the invention (comprising the composition o and at least one active ingredient) separately from the other constituent elements of the complex formulation and to mix them just prior to use. A non-limiting example of the invention will now be given: EXAMPLE 1) Preparation of composition 5 The following were introduced into a Stephan mixer: 900 g of anhydrous Na 3
PO
4 (pyrophosphate) 100 g of Geropon* TA 72 1200 g of water (ice). The mixture was ground for the period required to obtain a powder. The powder was then granulated by adding 200 g of water. 5 The granulates were dried in a fluidised bed at 1 10*C for one hour then in an oven at the same temperature for 2 hours. Following drying, the granulates had lost 6.3% of their weight. 2) Absorption of an active ingredient 14.4 g of granulates obtained as above (size less than 400 pm after sieving) were mixed 0 with 9.6 g of a Rhodorsil* 454 silicone composition (Rhodia), for 10 minutes. A dry powder was obtained, indicating good granulate impregnation. The amount of active ingredient was 40% with respect to the total granulate weight.
