Definitions

• the majority of the free-flowing, in particular powdered, textile detergents currently on the market is produced by spray drying or at least with the use of spray-dried components.
• a known technology is in particular the so-called spray mixing process.
• a substantial proportion of the finished detergent and cleaning agent mixture is converted by the spray process into a free-flowing or powdery material, to which the remaining components of the finished detergent are then added.
• ABS alkylbenzenesulfonate
• the invention is based on the object of providing new surfactant mixtures which are both easy to process in terms of production technology, and also when used in higher concentrations than previously stated, which do not adversely affect the free-flowing properties of a finished washing powder and, moreover, in the washing result with the known ones Mixtures shows at least comparable performance.
• the invention is based in particular on the object of making available surfactant mixtures of the type described, which are pourable or pumpable at room temperature and, consequently, to ensure particularly simple incorporation into pre-formed powdery components of a total detergent.
• the finished washing powders with a high surfactant content should not have any undesirable tackiness and thus should not restrict their flowability or flowability.
• the technical solution of the teaching according to the invention is based on the surprising finding that the subsequent surfactant multicomponent mixture is flowable and pumpable at room temperature, for example in the range around 20 ° C. - but also at even lower temperatures - and is therefore easy to mix into prefabricated powdery proportions of the finished detergent can be incorporated.
• the finished detergents show no signs of undesirable stickiness, even when incorporating up to 20% by weight of the flowable surfactant mixture, so that the desired aspired state of free-flowing or free-flowing dry detergent is fully preserved.
• the water content of this multicomponent mixture is preferably not more than about 15% by weight and in particular at most about 10-15% by weight, again based on the total water-containing surfactant mixture.
• ethoxylates with 10 EO are preferred, within component 3 alkanesulfonates.
• the preferred quantitative ranges - again in each case expressed as% by weight based on the water-containing surfactant mixture - for the components 1 to 4 are the following: Component of 1: 57 - 62% by weight Component of 2: 7-10% by weight Component to 3: 8 - 12 wt .-% as well Component of 4: 6-10% by weight.
• a mixture of active ingredients that is particularly suitable in practice can have the following composition - percentages here also understood as% active substance based on the total aqueous surfactant mixture - about 60% by weight of component 1, 8.5 - 9 wt .-% component of 2, 9-10% by weight of components of 3 and 8% by weight component of 4 as well as the rest of the water.
• the component 1 which is by far predominant in terms of quantity, is solid at room temperature and has a melting point which is approximately in the region of 30 ° C.
• the tallow alcohol sulfate salts (component 2) are also solid compounds at room temperature with melting points in the range of 55-60 ° C.
• Free tallow fatty acid (component of 4) has a melting point in the range of about 55 ° C.
• the components of 3 are also solid as salts. It was by no means to be expected that the incorporation of small amounts of water into such surfactant mixtures would result in pumpable, pourable compositions being formed under normal conditions.
• Suitable ethoxylated fatty alcohols are those with 12-18 carbon atoms and 9-11, preferably 10 EO groups.
• C 16/18 tallow sulfate salts are derived from cetyl alcohol-stearyl alcohol mixtures.
• Alkanesulfonate sodium salts are derived from an n-paraffin containing 12-16 carbon atoms.
• the tallow fatty acid (component to 4) consists essentially of palmitic acid, stearic acid and oleic acid.
• n-octylsulfosuccinate disodium salts which can be used in addition to or instead of the alkanesulfonate salt in the context of component 3 are known to be compounds of the general formula in which R represents a straight-chain C8-alkyl radical. These products are also commercially available.
• the invention relates to the use of the surfactant mixtures specified above in the manufacture provision of free-flowing, in particular powder detergents in at least partial exchange for their usual surfactant components based on ABS mixed with alcohol ethoxylates.
• the new surfactant mixtures are used in particular in the context of the production of free-flowing textile detergents by the spray-mixing method, where - as already stated - the finished free-flowing detergent can contain up to 20% by weight of the surfactant mixture which is flowable at room temperature.
• the detergents obtained in the sense of this inventive concept are distinguished by excellent washing properties. This applies both to detergents that contain conventional builder systems based on STP and to the detergent formulations desired today that are phosphorus-free and contain, for example, zeolite NaA as the main constituent of the builder.
• the surfactants or surfactant mixtures according to the invention are ecologically harmless, ie their toxicity to organisms living in water is particularly low and their biodegradability is very good. In this respect, they represent an important enrichment of the technological possibilities affected here.
• the active ingredient mixture described below was put together.
• the percentages of active substance (AS) are enclosed in brackets in the table below.
• the viscosity of this mixture of active ingredients is determined in a Höppler viscometer over the temperature range from 20 to 50 ° C, a gradual temperature increase of 5 ° C being selected.
• the washing behavior of the surfactant mixture according to the invention was determined by determination in launderometer washing under the following process conditions: 30 minutes treatment in a launderometer at 60 ° C, concentration of the detergent used 7 g / l, hardness of the water used for liquor preparation 16 ° dH.
• the following combination of active ingredients was used as detergent: 10 wt .-% surfactant mixture according to the invention 22% by weight sodium tripolyphosphate 15% by weight of zeolite NaA 5% by weight water glass 20% by weight sodium perborate 28% by weight sodium sulfate
• the reflectance values (double determination) determined on the washed test fabrics after washing, rinsing and drying were determined as follows: B64.0 / 64.9 PBV85.4 / 83.5 BV58.3 / 55.5
