Definitions

  • Aqueous acidic cleaner formulations are known. They contain tensides and acids as essential components.
  • the known acidic technical cleaners are used, for example, in dairies to remove deposits of lactic acid. They are also used to clean pipelines in which deposits of calcium and magnesium carbonates have formed.
  • the cleaning agent formulations In order to extend the exposure time of these technical cleaning systems when cleaning hard surfaces and thus to ensure optimal cleaning performance, the cleaning agent formulations must have a minimum viscosity to prevent the formulation from running off too quickly from the surface to be cleaned.
  • the viscosity of the known cleaner formulations is adjusted by using mixtures of different alkylphenol ethoxylates with different degrees of ethoxylation.
  • nonionic surfactants based on alkoxylated fatty alcohols, fatty acids, fatty amines, fatty acid amides or alkanesulfonamides are now used. However, the viscosity of such aqueous acidic cleaning formulations is not yet sufficient.
  • the present invention has for its object to provide aqueous acidic cleaner formulations which have an increased viscosity compared to the known acidic technical cleaners.
  • the cleaner formulations should also be stable in storage.
  • the detergent formulations can optionally contain further, conventional constituents, such as solubilizers, corrosion inhibitors and builders.
  • the aqueous acidic cleaning formulations contain, as an essential component (a), at least one nonionic surfactant based on alkoxylated fatty alcohols, fatty acids, fatty amines, fatty acid amides or alkanesulfonamides. These compounds are addition products of 3 to 40 moles of ethylene oxide with 1 mole of fatty alcohols, fatty acids, fatty amines, fatty acid amides or alkanesulfonamides each containing at least 8 carbon atoms.
  • the adducts of 3 to 20 moles of ethylene oxide with 1 mole of at least one alcohol having 10 to 18 carbon atoms are particularly preferred for use in the preparation of the aqueous acidic cleaner formulations.

  • the particularly preferred ethoxylated fatty alcohols contain 3 to 16 moles of ethylene oxide per mole of alcohol.
  • the amount of nonionic surfactants in the aqueous acidic cleaning formulations is 1 to 20, preferably 5 to 15% by weight.

  • at least 1 alkylene oxide having 8 to 30 carbon atoms or an alkyl or alkenyl glycidyl ether having 8 to 30 carbon atoms in the alkyl or alkylene radical is added to the reaction product thus obtained. If mixtures of alkylene oxides with 2 to 4 carbon atoms are used in the first reaction stage, one can either use random copolymers (ie the reaction is carried out with mixtures of alkylene oxides carried out) or block copolymers.
  • the block copolymers are formed by first reacting the compounds to be alkoxylated, for example, with ethylene oxide and then with propylene oxide or a butylene oxide.
  • the alkylene oxides are added in a known manner to 2- to 6-valent alcohols.
  • These polyfunctional alcohols can be alkane polyols, alkene polyols, alkyne polyols or oxialkylene polyols.

  • reaction products of the polyhydric alcohols with ethylene oxide and propylene oxide which contain ethylene oxide and propylene oxide in a weight ratio of 70:30 to 95: 5 added to a polyhydric alcohol are of interest. This can be either statistical polymers or block copolymers.
