Definitions

• the present invention relates to aqueous, storage-stable and action-stable liquid or pasty cleaning agents containing, in particular, chlorine-stable surfactants: an abrasive component and / or active chlorine-releasing compound, colorants and fragrances, and calcium aluminum silicate precipitated in situ.
• chlorine-stable surfactants an abrasive component and / or active chlorine-releasing compound, colorants and fragrances, and calcium aluminum silicate precipitated in situ.
• Bleaching detergents or abrasives should have this effect in the shortest possible time, namely during their use and at room temperature. As technically available bleaching agents for such liquid agents that meet these conditions and their loss of effectiveness
• Active chlorine-releasing compounds are known to be tolerable in aqueous solution.
• a liquid cleaning agent or scouring agent in particular based on these compounds, the task now was to find a medium which is particularly resistant to aqueous solutions containing active chlorine and which, on the one hand, is capable of suspending abrasive particles, if necessary, on storage, and on the other hand should have surface-active properties, so that the liquid cleaning or scouring agent, in addition to the pure scouring: and / or bleaching performance, also has the cleaning effect expected by the consumer against greasy soiling.
• EP 0 003 625 A1 also teaches that swellable clays are used to stabilize the suspension of hypochlorite-containing liquid abrasives.
• they have the disadvantage that they have such a strong thickening effect that they can only be used in small quantities and only for the stabilization of the suspension, specifically light abrasives namely preferred from there and exclusively used expanded perlites, but are not suitable for the stabilization of specifically heavy abrasives such as quartz or marble powder, which are also mentioned there and are usually used in real abrasives in amounts necessary for adequate abrasion performance.
• EP 0 009 942 A1 also discloses pourable liquid active chlorine abrasives which contain a combination of anionic and nonionic or ampholytic surfactants and an electrolyte.
• the chlorine stability of these Scheuerstoffsus is insufficient ensions p for sale products.
• aqueous, storage-stable and action-stable liquid or pasty, cleaning or scouring agents containing anionic and / or nonionic, in particular chlorine-stable surfactants and an abrasive component and / or an active chlorine-releasing compound are obtained if they are amorphous Calcium aluminum silicates are added, which are precipitated in situ, if appropriate in the presence of the abrasives which are preferably present.
• the suspension-stabilizing effect of Ca-Al-silicate precipitated in situ is not yet known and could not have been foreseen by the person skilled in the art.
• the Ca-Al silicate is obtained in X-ray amorphous form, has no swellability in water and, of course, no complexing effect against hardness-forming ions in tap water. Because of these properties, there is no analogy to other silicates known as components of cleaning agents.
• the Ca-Al silicate is produced in situ, preferably in the presence of abrasives. If it is manufactured separately and subsequently added to the liquid cleaning agent or abrasive, the suspension stabilization is significantly lower. Scanning electron micrographs show that, for example, CaCO 3 particles used as abrasives in abrasives according to the invention are coated with a uniform layer of smaller solid particles in the case of Ca-Al silicate precipitated in situ.
• the agents according to the invention can also contain colorants and fragrances, which may have to be chlorine-stable.
• the invention further relates to a process for the preparation of aqueous storage-stable and action-stable liquid or pasty cleaning or abrasive compositions containing optionally chlorine-stable anionic and / or nonionic surfactants, an abrasive component and / or an active chlorine-releasing compound, and optionally colorants and fragrances, which is characterized in that the abrasive component is optionally stirred into an aqueous solution of the surfactants and optionally the dyes at room temperature and, with further stirring, a calcium chloride solution, then an aluminum hydroxide solution, then a water glass solution and optionally the chlorine solution and the fragrance are added.
• a cleaning agent without abrasives can also be produced with the Ca-Al-silicate according to the invention.
• a thickened, thixotropic, preferably chlorine-containing cleaning agent with only an extremely weak abrasive effect is then obtained.
• a product has the advantage of adhering better to vertical surfaces, which has a positive effect on the quality of the bleaching effect.
• Such agents are known for example from DE-28 10 187 A1.
• the cleaning agents according to the invention are opaque, white suspensions which, even after prolonged storage, either do not separate at all or only so weakly that they can be homogenized again by gently shaking them before use.
• the claimed agents are applied by pushing them out of soft plastic bottles or tubes.
• the liquid abrasive obtained was thixotropic, had a relatively mild abrasive action and a very good bleaching action. After 1/4 year storage at room temperature, the suspension was unchanged and the chlorine loss was only about 22%.
• Example 2 The preparation was also carried out analogously to Example 1.
• the liquid abrasive had properties similar to those produced according to Example 1; the active chlorine loss after 3 months of storage at room temperature was only about 20%.
• This abrasive-free, active chlorine-containing thickened cleaning agent was also produced analogously to Example 1.
• This paste which also adhered well to vertical surfaces, was still homogeneous even after 6 months of storage at room temperature and the chlorine loss was less than 50%.
• This abrasive-containing, active chlorine-free abrasive was produced in accordance with the tasks in Example 1, but here was due to the lack of the active chlorine compound in the precipitation of the calcium aluminum um silicate before adding water glass by slowly adding dilute hydrochloric acid to a pH of about 10. The suspension was still stable after 3 months.
• the preparation was carried out analogously to Example 1, the copolymer was added after the marble powder. Before adding the water glass, a pH of 12.5 was set with dilute hydrochloric acid, which did not change after the liquid abrasive was finished.
• the pourable, bleaching abrasive showed similarly good storage results to both the suspension and the chlorine stability as the aforementioned examples.
