Definitions
- the invention relates to an auxiliary granulate, composed of cellulose and optionally cellulose / starch derivatives, polymeric binders and gel-forming surfactants, which are used as disintegrants for tablets in Washing and Detergent tablets is suitable. Furthermore, a method for Preparation of the granules and their use described.
- Disintegrants for tablets or granules are auxiliary substances that disintegrate Tablets or granules in contact with liquids, especially water influence positively. It is said that both the disintegration of tablets into rough parts also a subsequent disintegration into smaller particles up to dissolution / Dispersion of all detergent components can be effected and accelerated.
- Tablets are determined by pressing a starting granulate with Press produced, the bulk density, e.g. for compact detergents approx. 900g / l, after tabletting rises to 1200 g / l.
- Such tablets with higher densities than the starting granulate are naturally less soluble / separable as the starting granulate. Since they are in use in the However, the washing machine should dissolve quickly or should disintegrate and dissolve, it is appropriate to add disintegrants that promote decay.
- the addition to the induction chamber is the most convenient for the user and for the user The safest quality of the washing process.
- the first step of disintegrating the tablet into large parts must be done very quickly go, because otherwise residues of the tablet remain in the dispenser and not can be used for washing.
- washing machines take about 30 seconds to rinse the tablets over the induction bowl available.
- the tablets must be used when hot perform their function even with cold induction water. Lie in the washing drum other conditions for the disintegration of the tablet, since both mechanical Friction as well as rising water temperatures the dissolution process of the tablet influence.
- DE-OS 2 251 249 e.g. rapidly disintegrating pharmaceutical tablets described by pressing pharmaceutical granules and Disintegrant granules are produced.
- the use of granular Starting materials lead to a porous tablet structure.
- An example is Disintegrant granules based on starch with a particle size of 2.0 to 0.3 mm used.
- No. 3,629,393 claims pharmaceutical tablets with delayed release of the active ingredient, which are pressed from granular components, disintegrants from high-molecular, water-swellable compounds, such as cellulose derivatives, being used in the form of granules.
- the granule dimensions in the examples are around 0.84 mm.
- US 4,072,535 describes the use of disintegrants made of precompacted starch for pharmaceuticals and detergents.
- the grain size of the compact is 0.05 mm to 0.42 mm, the moisture content is stated as 9-16%, preferably 11-13%.
- the disintegration times of the sample tablets are several minutes.
- Detergent tablets are known from DE-OS 2 321 693, which contain 1 to 25% by weight. contain fibrous cellulose as a disintegrant. In the examples Tablets made with a strength of 15 to 19 N, being compacted Cellulose granules can be used.
- tablet-like washing additives consist of granular constituents are pressed, 1 to 5% by weight also being granular tablet disintegrant based on cross-linked Polyvinyl pyrrolidone and / or cellulose ethers are used.
- the granules should be free of dust.
- the tablets have a breaking strength of 50 up to 120 N and have long dissolving times of several minutes.
- washing or cleaning-active moldings which can be produced using an explosive granulate that has a high Has adsorption capacity for water and a grain size distribution in which at least 90% by weight a particle size of at least 0.2 mm and a maximum of 3 mm have.
- the dust content ⁇ 0.1 mm is less than 1%.
- the explosive granules contains at least 20% by weight of disintegrants, such as starch, starch derivatives, Cellulose, cellulose derivatives. According to the teaching of this patent, this has an effect Presence of anionic or nonionic surfactants negatively affects the Tablet disintegration time.
- the granules are made in a conventional manner manufactured, such as spray drying, superheated steam drying of aqueous preparations or by granulation, pelleting, extrusion or roller compaction powder components. Detailed procedural information on Granulation process or further process steps after the granulation the explosive granules are not made.
- the example produced Detergent tablet contains a disintegrant based on compacted cellulose thermochemically treated wood pulp and has a tablet hardness of 45 N. on. Tablets of higher strength, i.e. above 50 N are not described.
- WO 98/55575 describes an auxiliary granulate for washing and detergent active moldings.
- the claimed auxiliary granules contain 10 to 95% by weight cellulose with particle sizes below 0.1 mm and 5 to 90% by weight microcrystalline cellulose.
- the celluloses partially with carboxymethyl cellulose, TAED and citric acid / bicarbonate combined.
- the grain sizes of the compact are more than 90% by weight from 0.3 to 2.0 mm, less than 5% by weight less than 0.2 mm and have no dust content.
- the Roll compacting of the dry premix is preferred. Detailed Process details for the production of granules are not given.
- the below Use of the auxiliary granules produced by way of example Detergent tablets have low strengths of 35 N or less. More stable, more compact tablets with higher strength from 50N not described.
- Patent application WO 98/40462 describes a compact made of powdered and / or granular ingredients, in particular detergent ingredients, which contains particles of cellulose-containing material acting as disintegrant, the can also be in a compact form.
- Particularly preferred as Cellulose components become thermomechanical (TMP) and chemical thermomechanical (CTMP) treated wood pulps.
- TMP thermomechanical
- CMP chemical thermomechanical
- the particle size of the compacted explosives can range from 0.2 to 6 mm.
- About the Cellulose components can also add tenside raw materials to the compact be mentioned, with 0.5 - 5% surfactant / compact. That corresponds to one Surfactant content of approx.
- the state of the art also includes sales products from Degussa AG with the designation Elcema G250 and Elcema G 400, which consists of compact Pure cellulose exist and have been used as a tablet disintegrant since 1971 become. These products are made by dry granulation and have a particle size of 0.03 to 0.40 mm. The moisture content is ⁇ 6%.
- the object of the invention is therefore one compared to the prior art to provide improved disintegrant granules for tablets.
