Definitions

• the present invention relates to a liquid detergent based on nonionic and anionic surfactants and particulate builders with additives which are particularly effective in strengthening washing power against oil and grease-like soiling.
• a liquid detergent based on nonionic surfactants and particulate builders which contains a surfactant liquid component made of nonionic and anionic surfactants as well as polyethylene glycol with a molecular weight of about 200 to 600.
• the addition of polyethylene glycol brings about an improvement in the viscosity behavior and the dissolving speed of the detergents according to the teaching of DE-A-36 21 536.
• the polyethylene glycol makes virtually no contribution to the washing result.
• the object of the present invention was therefore to provide liquid detergents with perfect viscosity behavior and high dissolving speed and improved washing power.
• the present invention therefore relates to an anhydrous liquid detergent based on nonionic and anionic surfactants and, if appropriate, particulate builders, which is characterized in that it contains a non-surfactant, washing-strengthening component made from a combination of low-polar and medium-to-high polar organic liquids.
• Low polar organic liquids in the sense of the present invention are aliphatic and / or cycloaliphatic, in particular straight-chain or branched paraffin hydrocarbons with 8 to 40 carbon atoms or mixtures of different hydrocarbons. It is important for the selection of suitable hydrocarbons in the context of the present invention that they have a liquid to at most waxy consistency at room temperature.
• Another essential characteristic for particularly suitable low polar organic liquids is the flash point of the liquid, which, measured according to DIN 51 758, must exceed + 40 ° C.
• Another important characteristic for particularly suitable low polar organic liquids is their pour point, measured according to DIN 51 583, of at most +10 ° C.
• generally low polar organic liquids with a consistency that is waxy at room temperature can be used are, in particular movable liquids with a viscosity of less than 100, in particular less than 50 mPas at 20 ° C are suitable.
• Corresponding liquid paraffin oils generally contain compounds with 8 to 20 carbon atoms.
• Liquid detergents in the context of the present invention with particularly balanced properties contain the low polar component and the medium to high polar component in a weight ratio of 5: 1 to 1: 2, in particular in a weight ratio of 1: 1 in amounts of 1 to 20 percent by weight, based on the entire detergent.
• the content of this detergent-enhancing component is preferably 5 to 15 percent by weight, based on the total detergent.
• a detergent with particularly balanced properties with regard to its washing performance, its viscosity behavior and its dissolving properties contains paraffin oil with 8 to 20 carbon atoms and dibutyl phthalate as a non-surfactant, detergent-enhancing component, preferably in an amount of 8 to 12 percent by weight, based on the total detergent, in particular in an amount of 10 Weight percent, the weight ratio of the low polar to medium to highly polar organic liquid in the range from 2: 1 to 1: 2, in particular 1: 1.
• Detergents according to the invention have a significantly better washing performance on grease-specific cosmetic soils compared to detergents of the prior art, which contain polyethylene glycol instead of the non-surfactant-strengthening component according to the present invention.
• the detergents according to the invention contain a bleaching component or enzymes, bleachable and protein-containing soiling is also removed perfectly. There is no objection to the foaming behavior of the detergents according to the invention in household washing machines.
• the particulate builders contained in the detergents according to the invention are organic and inorganic substances, preferably alkaline salts, in particular alkali salts, which not only are able to precipitate or bind complex calcium ions, but also, as far as possible, bring about a synergistic increase in washing power with the surfactants and have a dirt-carrying capacity .
