Definitions
- the present invention relates to the field of machine dishwashing detergents for household dishwashers. It relates to detergent components for use in machine dishwashing detergents (MGSM) and to detergent compositions and detergent tablets containing such components
- MGSM machine dishwashing detergents
- the automatic cleaning of dishes in household dishwashing machines usually includes a fast-forward cycle, a main-wash cycle and a rinse-aid cycle, which are interrupted by intermediate rinse cycles. Most machines can switch on the fast-forward cycle for heavily soiled dishes, but are only selected by the consumer in exceptional cases, so that m Most of the machines have a main rinse cycle, an intermediate rinse cycle with pure water and a rinse aid cycle.
- the temperature of the main rinse cycle varies between 40 and 65 ° C depending on the machine type and program level selection.
- rinse aid cycle rinse aid is added from a metering tank in the machine, which is usually the non-ionic main component Containing surfactants
- Such rinse aids are in liquid form and are widely described in the prior art. Their main task is to prevent limescale and deposits on the cleaned dishes. In addition to water and mild showers These rinse aids often also contain nonionic surfactants, hydrotopes, pH-adjusting agents such as citric acid or scale-inhibiting polymers
- the storage tank in the dishwasher must be filled with rinse aid at regular intervals, whereby one fill is sufficient for 10 to 50 rinse cycles, depending on the machine type. If the tank is forgotten, glasses in particular become stained with limescale and Unsightly toppings. In the prior art there are therefore some proposed solutions for integrating a rinse aid into the detergent for machine dishwashing.
- European patent application EP-A-0 851 024 (Unilever) describes two-layer detergent tablets, the first layer of which contains peroxy bleach, builder and enzyme, while the second layer contains acidifying agents and a continuous medium with a melting point between 55 and 70 ° C. and scale inhibitors contains. Due to the high-melting continuous medium, the acid (s) and scale inhibitor (s) should be released with a delay and cause a rinse aid effect. Powdered machine dishwashing detergents or surfactant-containing rinse aid systems are not mentioned in this document.
- German patent application DE 198 51 426.3 (Henkel KGaA) describes a process for the production of multiphase detergent tablets in which a particulate premix is pressed to give moldings which have a trough which is later made from a meltable melt with a separately produced melt Substance and one or more active substance (s) dispersed or suspended in it.
- the teaching of this document is also tied to the "tablet" offer.
- melt suspensions or emulsions disclosed in the last-mentioned document have long-term stability in need of improvement, especially when incorporating surfactants as active substances.
- the meltable substances should enclose the active substance and protect against premature release. If the emulsion is insufficiently stable, it partially separates in the molten state before metering, which leads to metering accuracy. Slightly more stable emulsions can be dosed, but they partially separate before solidification, so that the active substance is released early in the cleaning cycle.
- this document discloses the use of various aids or stabilizers. If solids are mentioned, however, no statements are made about their physical properties.
- the present invention was based on the object of further developing the teaching of the older German patent application DE 198 51 426.3 and of providing long-term stable mixtures which do not tend to separate during metering and cooling and are therefore effective and stable detergent components deliver These long-term stable mixtures and the detergent components made from them should make all known advantages of the controlled release of ingredients, in particular a rinse aid, usable for powder detergents and detergent tablets
- meltable hydrophobic substances with melting points above 30 ° C., tenside (s) and optionally further ingredients such as colorants and fragrances, etc., if these mixtures have at least 0.1% by weight of finely divided solid (e) included
- the melting point of such mixtures can be specifically adjusted to the desired value by the type and amount of the individual ingredients, in particular the melting points and amounts of meltable substance (s) and tenside (s). Above the melting point, mixtures which are stable to separation are present , below the melting point solidified mixtures in any shape, which are referred to in the present application as detergent components
- the present invention relates to a cleaning agent component which contains a) 10 to 89.9% by weight of surfactant (s), b) 10 to 89.9% by weight of fusible substance (s) with a melting point above 30 ° C. and a lack of water of less than 20 g / l at 20 ° C., c) 0.1 to 15% by weight of one or more solids, d) 0 to 15% by weight of further active substances and / or auxiliaries, with the proviso that at least 90 % By weight of the particles c) have particle sizes below 300 ⁇ m
- detergent component in the context of the present application characterizes solidified melts from the ingredients a) to d), regardless of their shape. “Detergent component” in the sense of the present application are therefore, for example, scales, pills, lozenges, shaped body areas, shaped bodies per se etc.
- both ingredients are separated or melted in a mixture with one another, if necessary combined and stirred with the addition of c) and optional addition of d).
- the melt suspension or emulsion produced in this way which is also referred to below for short as “mixture”, can then be converted into the desired shape.
- Preferred detergent components contain 15 to 80, preferably 20 to 70, particularly preferably 25 to 60 and in particular 30 to 50% by weight of surfactant (s) as ingredient a). All surfactants from the groups of anionic, nonionic, cationic or amphoteric surfactants can be used, preferred detergent components being characterized in that they contain, as ingredient a) anionic and / or nonionic surfactant (s), preferably nonionic (s) surfactant (s) included.
- Anionic surfactants used are, for example, those of the sulfonate and sulfate type.
- the surfactants of the sulfonate type are preferably Cg-u-alkylbenzenesulfonates, olefin sulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates such as those obtained from with a terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.
