Definitions

  • This descriptive report refers, as its title indicates, to a procedure for colouring granulated non-adsorbent minerals and the product thus obtained of the type used in the field of chemical products and processes leading to coloured speckles used in the detergent industry being obtained, characterised in that it allows coloured granules, also known by the English tem "speckles", to be obtained which are particularly used as coloured speckles present in powdered detergents.
  • These coloured granules are obtained from non-adsorbent mineral particles with a diameter of between 300 and 2,000 ⁇ m using a granular base of the same size, a binding agent and a colouring agent or pigment, all by means of a characteristic production procedure.
  • WO 98/16615 discloses colored particulate compositions comprising an inner core having a color body distributed on a particulate carrier, and two discrete coatings of water-soluble dextrin glue on said inner core.
  • the compositions are useful as speckles in cleaning products, especially laundry bars, having a contrasting background color. Also disclosed is a process for preparing said colored particulate compositions.
  • WO 00/27980 discloses a cleaning composition speckle particles having a specific sparkle index and transparency index, the particle comprising solid material, preferably specific crystalline material, which is colored by addition of a dye pigment and/or a brightener.
  • WO 00/27980 also relates to cleaning compositions comprising the speckle particles of the invention, in particular laundry and dish washing compositions.
  • GB 2199338 A discloses a process for the production of coloured detergent powder comprising mixing a spray-dried detergent powder with a dyestuff and then treating the resulting mixture with a binder.
  • preferred dyestuffs are copper and nickel phthalocyanines and Red Carmin Microsol-FBS-X.
  • Suitable binders are aqueous solutions of acrylic or acrylic/maleic polymers, water alone and aqueous sodium silicate, potassium or sodium triphosphate or sugar.
  • the coloured powder may be used to provide "speckles" in a white detergent powder.
  • non-adsorbent salt which is a monocrystal inorganic salt with a grain size of between 300 and 2,000 ⁇ m, preferably between 600 and 1,500 ⁇ m, of a hygroscopic nature in order to be able to fix the colouring agent, so these are mainly inorganic salts, such as sodium carbonate, sodium tripolyphosphate, sodium chloride, sodium sulphate among others.
  • the colouring agent is responsible for providing the desired colour to the inorganic salt and any pigment or colouring agent allowed in the detergent industry or any preparation thereof, which must have a
  • the binding agent is necessary to obtain a film, which fixes the colouring agent to the inorganic salt substrate, as it is a non-adsorbent material. This acts by generating a surface layer which fixes the colouring agent to the substrate and which is compatible with formulations in the detergent.
  • binding agents which may be used and which are found in literature, we may cite among others, sodium silicate, different types of polymers, carboxymethyl cellulose (CMC), etc.
  • the colouring procedure comprises a sequence of three main phases, which in their turn are divided into different intermediate steps.
  • This colouring procedure is carried out in a industrial rotary mixer of the endless screw or mixing blade variety, with a jacket or encasing double wall equipped with a peripheral water heating circuit and also equipped with a hot air injection system inside.
  • the appropriate temperature control and regulatory devices must be available both for water circulating in the jacket and for the hot air, to allow precise control of the working temperatures to prevent the formation and agglomeration of hydrated compounds.
  • the procedure for colouring granulated, non-adsorbent minerals and the product thus obtained which forms the object of this invention consists of a characteristic sequence of phases (1,2,3) in which a non-adsorbent mineral (4) or substrate is mixed with a colouring agent (9) and a binding agent (11).
  • the process is based on a non-adsorbent mineral (4), preferably a monocrystal inorganic salt with a grain size of between 300 and 2,000 ⁇ m, preferably between 600 and 1500 ⁇ m, so it is not necessary to carry out an agglomeration process for it to achieve the desired size and, given the monocrystalline nature of the product obtained, it is hard enough to withstand the effect of friction during mixing with the rest of the components.
  • a non-adsorbent mineral (4) preferably a monocrystal inorganic salt with a grain size of between 300 and 2,000 ⁇ m, preferably between 600 and 1500 ⁇ m, so it is not necessary to carry out an agglomeration process for it to achieve the desired size and, given the monocrystalline nature of the product obtained, it is hard enough to withstand the effect of friction during mixing with the rest of the components.
  • the colouring agent (9) can be fixed (9), so that sodium carbonate, sodium tripolysulphate, sodium chloride, sodium sulphate among others may be
  • the colouring agent (9) is responsible for providing the desired colour to the non-adsorbent mineral (4) and for this any pigment or colouring agent allowed in the detergent industry or any preparation thereof, which must have a granulometry of between 0.01 and 15 ⁇ m, preferably between 0.01 and 5 ⁇ m, is used, thus maintaining its visibility and facilitating the homogeneity of the colour in the subsequent process and avoiding stains in the product because of a larger size.
  • the commonest ones that may be used in the process we may cite: Pigment Blue 15, Pigment Green 7, Pigment Yellow 3, Pigment Red 57, Food yellow 3, Food Blue 5, Acid Green 1, Acid Yellow 4, among others.
  • the binding agent (11) is necessary to obtain a film, which fixes the colouring agent (9) to the inorganic salt substrate. Moreover, being non-adsorbent materials, the pigment or colouring agent must be fixed to the grain.
  • the binding agent (11) acts by generating a surface layer, which fixes the colouring agent (9) to the inorganic salt substrate (4), allowing it at the same time to be compatible with the formulations in the detergent.
  • binding agents (11) which may be used in this process, we may cite among others, sodium silicate, different types of polymers, carboxymethyl cellulose (CMC), etc ., preferably soluble sodium silicate because of its readiness to form vitreous layers with the above features when its diluting water dries up.
  • the colouring procedure characteristic of the invention comprises a sequence of three main phases, which in their turn are divided into different intermediate steps.
  • the phase starts with the initial step of loading (5) the mixer (17) with the non-adsorbent mineral (4), where the step of heating the product (6) above its hydration temperature is carried out, if it has one. To do this, the jacket (18) is heated at the same time above this temperature and hot air is introduced into the mixer (17).
  • the phase continues with the step of lowering the temperature (7) of the jacket (18) below the temperature of the product followed by the step of introducing (8) the colouring agent (9) in the form of a preparation.
  • the jacket (18) be below the temperature of the product in order to avoid incrustations. This may be achieved in two ways: by keeping it constant just above the hydration temperature or by maintaining a constant difference with the temperature of the product.
  • the colouring agent (9) will be added in suspension with water and, if necessary, with some kind of dispersant.
  • concentration of colouring agent (9) in the preparation will be preferably between 15 %, to avoid using a lot of water which will evaporate afterwards, and 60 %, to allow a good mix and close contact between the substrate (4) and the colouring agent (9), as the medium which puts them in contact and allows them to join is water, although they are fixed by the binding agent (11) in the subsequent drying process.
  • the addition to the mass will be made with sufficient time for mixing, preferably between 10 seconds and 5 minutes, depending on the mixing capacity of the equipment.
  • the proportion of colouring agent (9) to be used in relation to the non-adsorbent mineral (4) varies between 0.001% and 10%, preferably between 0.01% and 1%.
  • the introduction of the colouring agent (9) should be carried out preferably by means of spray nozzles or a shower to make mixing easier.
  • step of adding (10) the binding agent (11) is carried out several times (13) to facilitate homogeneity and avoid incrustations.
  • a drying step (12) is then carried out by introducing hot air into the mixer (17) to dry after each step of adding (10) a binding agent (11).
  • the method of introducing this hot air, its rate of flow and temperature will result in less time and, therefore, greater production capacity, resulting in fewer operational costs.
  • the temperature of the drying air must be preferably between 100 and 300° C, depending on the physical characteristics of the substrate (4), colouring agents (9) and binding agent (11) chosen.
  • the rate of flow of hot air to be introduced should be such that it is sufficient to dry and keep the bed spongy if necessary, but avoiding elutriates (solid product carried away by the air) being produced. As high granulometry is involved, excessive amounts of elutriates are not generated and this solved by installing a sleeve filter or an air washer at the outlet for the exhaust air.
  • the number of times (13) that the cycle of adding (10) and subsequent drying (12) steps is 5 by way of example, thus optimising the process in accordance with the type of mixer and product.
  • the temperatures on addition (10) depend on the equipment, the number (13) of additions intended, the substrate (4) load, the temperature of the cooling jacket (18) and the characteristics of the drying air.
  • the increase in temperatures between additions (10) should preferably be between 2 and 10° C. In this way a dry product will be obtained, preferably with humidity of less than 5% in weight.
  • the method of adding (10) the binding agent (11) should enhance uniform distribution throughout the product without generating any kind of agglomerate (either of product or dry residue of the binding agent itself) and avoid giving rise to incrustations.
  • adding is carried out over various steps emulating an on-going addition (10) and drying (12) process. That is to say, an addition (10) is made and we wait for this product to be dry enough for the next addition to be made.
  • the number of additions (13) simulates an on-going process of addition and depends on the percentage of binding agent (11) necessary for each size of grain and substrate (4).
  • the percentage addition of binding agent (11) may vary between 2 % and 10 %, the number of additions to fulfil the conditions of the first heading being a total of between 1 and infinity (exactly what an on-going addition process would be).
  • a suitable number of additions is between 2 and 10. Below this amount there is the risk of generating incrustations and agglomerations and above, the process is affected energy wise.
  • each one of the different additions (10) should be made in a way that allows a good mix.
  • the addition to the mass will be made with sufficient mixing time, preferably between 10 seconds and 5 minutes, depending on the mixing capacity of the equipment.
  • binding agent (11) should be by means of spray nozzles or a shower to make mixing easier.
  • binding agent (11) will be added continuously throughout the drying process (12).
  • a cooling process of the end product (16) must be carried out as otherwise the hygroscopic nature of the inorganic salts (4) being treated would cause condensation effects during storage.
  • a suitable temperature for finishing the process and considering the product as finished (and cold) would be around 30-60° C.
  • the cooling process is carried out by means of a step introducing cold air (14) and another simultaneous step introducing cold water (15) into the jacket (18). Cold is considered to be at a temperature around room temperature.
  • the rotating speed of the mixing element (17) may be varied by controlling the rotating motor (20) in order to improve each one. These revolutions should not be excessive in order to avoid stirring the granules too violently causing them to break and fine materials to be produced.
  • the following preferred values for each one of the above stages in a horizontal mixer (18) may be given:
  • revolutions during the process will fluctuate between 1 and 150 rpm in the mixing element, depending on the type of product, equipment and process.
  • the choice of the type of revolutions will directly influence the process time and, therefore the production capacity however, this will not have any great effect on the quality of the product.
  • the mixer (17), which may be used for this invention, may be any of those used in industry, preferably the horizontal type with flat blades and having the following components:
  • V/SA volume/surface area ratio of the jacket (18) should be optimised in order to avoid loss of energy and incrustations of the product.
  • This volume/surface area ratio should likewise optimise the contact surface of drying air with the product and therefore increase the production capacity for a given volume. This ratio will be different depending on the type of mixer (17).
  • the volume of product should be such that the formation of incrustations is prevented as, due to abrasion, they do not occur on the actual product bed.
  • the occupied volume should be such as to allow mixing and minimise incrustations. In most equipment this percentage fluctuates between 50 and 100 % of the total volume of the equipment, which allows movement of the mixture.
  • a production batch of coloured speckles of different colours is made, based on granular sodium sulphate with a constant jacket temperature, with the following mixer and process characteristics: Characteristics of the substrate.
  • Characteristic Value Compound Granular sodium sulphate Average size 900 ⁇ m Apparent density 1.6 Kg/l Initial humidity 0.03 % Characteristics of the binding agent Characteristic Value Compound Soluble sodium silicate Percentage of total addition to substrate (in N additions) 5 % Characteristics of the different colouring agents Characteristic Value Colouring agent 1 (Green) Pigment Green 7 (35 %) Colouring agent 2 (Blue) Pigment Blue 15 (35 %) Colouring agent 3 (Orange) Food Yellow 3 (35 %) Percentage addition of preparation 0.20 % Characteristics of the mixer Characteristic Value Type of mixer Horizontal with flat blades Volume of mixer 3,000 litres V / SA ratio 0.26 m 3 /m 2 Characteristics of process Characteristic Value Substrate load 3,000 Kg.
  • the sulphate thus obtained contains 97.4% pure sodium sulphate, higher than the methods currently used, since, as stated, the consumption of raw materials is less.
  • the remaining properties (granulometry, density, etc.) remain very similar to the starting product as practically no grains have been broken.
