Definitions

• the present invention relates to aqueous, storage- 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.
• Bleaching detergents or abrasives should have this effect in the shortest possible time, namely during their use and at room temperature.
• Compounds which release active chlorine are known as technically available bleaching agents for such liquid compositions which meet these conditions and whose loss of action can be tolerated in aqueous solution.
• EP-A-0003625 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 of specifically light abrasives, namely from there preferred and exclusively used expanded perlites, but not for the stabilization of those also mentioned there and usually in real ones
• Abrasives that are used, specifically heavy abrasives such as quartz or marble powder are suitable in amounts required for sufficient abrasion performance. These sediment even through thixotropic pastes and form an irreversible sediment.
• aqueous, storage- and action-stable liquid or pasty, cleaning or abrasives 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-AI silicate precipitated in situ has hitherto not been known and could not have been foreseen by the person skilled in the art.
• the Ca-AI silicate is obtained in X-ray amorphous form, has no swellability in water and, of course, no complexing effect against hardness-forming ions in the 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, CaC0 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 CaC0 3 particles are otherwise the same composition with a subsequently added equal amount of precipitated Ca-Al silicate, or Zu given a corresponding amount of commercially available hectorite clay (Na-Mg silicate), unchanged as a mixture with the finer solid particles.
• the agents according to the invention can also contain colorants and fragrances, which may have to be chlorine-stable.
• the invention relates to a process for the preparation of aqueous storage-stable and action-stable liquid or pasty cleaning or abrasive agents with a content of 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 certain pH value of the end product is to be set, which, however, should not be below 11.5 in the case of chlorine-containing cleaning agents for the known reasons of chlorine stability, this can be between the addition of the aluminate solution and the water glass solution with a chlorine-stable acid such as e.g. Hydrochloric acid, phosphoric acid or phosphonobutane tricarboxylic acid can be set.
• a chlorine-stable acid such as e.g. Hydrochloric acid, phosphoric acid or phosphonobutane tricarboxylic acid
• a cleaning agent without abrasives can also be produced with the Ca-AI silicate according to the invention.
• a thickened, thixotropic, preferably chlorine-containing cleaning agent is then obtained with only an extremely weak abrasive effect.
• 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-A-2810187.
• 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 carried out analogously to Example 1. It was a thixotropic abrasive paste with a weak abrasive effect. After 3 months of storage, the suspension remained homogeneous. The active chlorine content was practically retained.
• the liquid abrasive had properties similar to those of Example 1; the active chlorine loss after 3 months' storage at room temperature was only about 20%.
• alkanesulfonate Na salt 60%, as in Example 1, 6.0% amine oxide, as in Example 1, 5.0% chlorine bleach, 12-16% active chlorine, 45.0% marble powder, average particle diameter 15 ⁇ m , 5.6% Ca-AI silicate precipitated in situ, 0.2% fragrance, remainder water, fully desalinated.
• alkanesulfonate Na salt 60%, as in Example 1, 6.0% amine oxide, as in Example 1, 5.0% Chlorine bleach, 12-16% active chlorine, 13.0% Ca-AI silicate precipitated in situ, 0.2% fragrance, remainder water, fully desalinated.
• 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%.
• 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 stability and the chlorine stability as the aforementioned examples.
