Definitions
- the present invention relates to pasty detergents for use in commercial laundries, a method for producing such compositions and a disinfectant washing method in commercial laundries.
- Detergents used in the household are tailored to the needs there; they are usually powdery or sufficiently liquid to be poured out and dosed easily. Since liquid detergents of this type are also said to be stable in storage within relatively wide temperature ranges, additions of organic solvents and / or hydrotropes are frequently added, but these do not themselves contribute to the washing or cleaning result and are therefore undesirable. A possibility for circumventing possible dosing problems with insufficiently liquid agents is proposed in the European patent application EP 253 151 A2.
- liquid, partly highly viscous detergents based on nonionic and anionic surfactants which contain polyethylene glycol as hydrotrope and which do not have to be dosed by the user in liquid form, but rather are packed in portions in bags made of water-soluble material, for example polyvinyl alcohol.
- the paste-like detergent described in the European patent EP 295 525 B1 consists of a phase which is liquid in the temperature range below 10 ° C. and which is formed from nonionic surfactant, and a solid phase of a certain particle size dispersed therein, which is formed from washing alkalis, sequestering agents and optionally anionic surfactants becomes.
- surfactants or their mixtures are used, the pour point (solidification point) of which must be below 5 ° C in order to avoid solidification of the paste at low transport and storage temperatures.
- This detergent paste is intended for commercial laundries and is so fluid that it can be conveyed via a suction line using a conventional feed pump.
- Another paste-like detergent which, as a nonionic surfactant, comprises 40 to 70% by weight of ethoxylated fatty alcohol with 10 to 20 carbon atoms which is liquid at room temperature and an average degree of ethoxylation of 1 to 8 and 20 to 50% by weight of ethoxylated and propoxylated fatty alcohol which is liquid at room temperature
- ethoxylated fatty alcohol with 10 to 20 carbon atoms which is liquid at room temperature and an average degree of ethoxylation of 1 to 8 and 20 to 50% by weight of ethoxylated and propoxylated fatty alcohol which is liquid at room temperature
- This pasty washing or cleaning agent is so strictly viscous that it is not flowable at room temperature under the influence of gravity, but has a significantly lower viscosity when sheared and is then flowable under the influence of gravity.
- the metering of this pasty detergent or cleaning agent is preferably carried out by subjecting the agent to lowering the viscosity to shear and then metering the flowable agent by means of feed pumps.
- a pasty detergent for use in commercial laundries which contains nonionic surfactant, organic and / or inorganic builders, alkalizing agents and optionally bleaching agent, enzyme, graying-inhibiting polymer and / or other conventional ingredients and characterized in that it contains 5% by weight to 30% by weight of an ethoxylated alcohol of the general formula R 1 - (OC H- 4 ) m -OH (I), in which R 1 is an alkyl or alkenyl radical with 9 is up to 15 carbon atoms and the average degree of ethoxylation m can assume values from 1 to 8, 1% by weight to 20% by weight of an ethoxylated alcohol of the general formula R - (OC 2 H- t ) n -OH (II ), in which R is an alkyl or alkenyl radical having 12 to 22 carbon atoms and the average degree of ethoxylation n can assume values from 3 to 14, with the proviso that
- alkalizing agent l in particular alkali metal silicate, 1% by weight to 20% by weight medium- to long-chain alcohol or alkyl ether of the general formula R 3 -OR 4 (III), in which R 3 is an alkyl or alkenyl radical with 6 to 22 C- Atoms, in particular 8 to 22 carbon atoms and R 4 hydrogen or an alkyl radical with 1 to 6 carbon atoms, and contains up to 15% by weight of organic builders of the polymeric polycarboxylate type, polymeric polycarboxylates being understood as meaning polymerization products of unsaturated mono- and / or dicarboxylic acids which, apart from Carboxyl groups have no further functionalities.

- there is a greater demand for efficient cleaning processes in commercial laundering than in household laundry since extremely soiled laundry and infected hospital laundry can occur.
- commercial laundries wash almost exclusively with water that has been freed from hardness ions.
- the agents known from the documents mentioned above have a high cleaning performance and are very well suited for the commercial washing of soiled laundry.

- This premix preferably after heating to temperatures in the range of approximately 80 ° C., is admixed with the powdery constituents, including the citric acid / citrate of the pasty agent, which are dispersed in the premix, in particular by stirring. Then the premix. The mixture thus obtained is then preferably subjected to a wet grinding process. This gives the product the desired consistency and homogeneity. Additional, in particular temperature- or shear-sensitive, ingredients such as perfume oils and enzymes are then mixed in, the homogeneous incorporation of which should be done as gently as possible so as not to destroy the structure of the paste.
