Definitions

  • the invention relates to cleaning agents for hard surfaces. As such are all non-textile that occur in the household and commercial sector Surfaces, with the exception of dishes.
  • all-purpose cleaner has come up for this type of cleaning agent naturalized. All-purpose cleaners have been known for a long time. It is about essentially aqueous surfactant solutions of various kinds with or without the addition of builders and with or without the addition of water-soluble ones Solvents or solubilizers. The consumer hires such all-purpose cleaners meet the requirement of all types of im Household soiling to be effective. Conventional weakly alkaline or neutral all-purpose cleaners meet this requirement as far as possible with regard to oily, greasy and dusty soiling. Beyond that, the consumer also expects that above all calcareous contamination occurring in the bathroom, but also in the kitchen area are easily removable; to meet this need the production of acidic all-purpose cleaners is ideal.
  • the object of the present invention is to provide acidic, easy-to-assemble, cold and storage-stable cleaning agents with good cleaning power for hard surfaces, so-called general-purpose cleaners, which also show the above-mentioned requirement profile without the use of hydrotropes.
  • the object was achieved by combining a C 6 -C 11 alkyl glycoside with a specific fatty alcohol ether.
  • EP-A-0 202 638 describes cleaning concentrates of C 8-12 alkyl glycoside, an adduct of EO and PO or butylene oxide on a C 6-16 alcohol, water and a combination of solubilizers (hydrotropes) based on organic acids for strongly alkaline cleaning formulations .
