Definitions

  • the present invention relates to toilet cleaner blocks, more particularly to toilet cleaner blocks comprising a surfactant mix of alkyl benzene sulfonate, primary alcohol sulphate and alkyl poly glycoside.
  • Toilet cleaner blocks are commonly used to impart cleansing and/or other components to the flush water of toilets, like lavatories or urinals. Such blocks may be immersed in the water tank (so called in-tank blocks or cistern blocks) or held under the rim of a toilet in a suitable holder for intermittent contact of the toilet cleaner block with flush water (so called rim blocks).
  • Rim blocks typically contain active ingredients such as surfactants, perfume, acids, bases, salts, thickeners, antimicrobials, preservatives, sequestrants, bleaching agents, corrosion inhibitors, flush regulators, enzymes, microorganisms, active substances for biofilm removal, lime-scale inhibitors, soil-adhesion inhibitors etc. Rim blocks also often contain a substantial amount of filler, such as sodium sulphate or sodium carbonate.
