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.
