Definitions

  • This invention is concerned with improvements in and relating to lavatory cleansing compositions. More particularly, the invention is concerned with solid lavatory cleansing compositions which may be used to impart cleansing and/or other components to the flush water of a lavatory or urinal.
  • compositions to impart cleansing and/or other components to the flush water of a lavatory or urinal are well established.
  • Such compositions may, for example, be immersed in the water of a lavatory cistern either in free-standing form or in containerised form (i.e. in a dispensing container which allows for release of components of the solid composition in solution in water in a more or less metered fashion, on flushing of the cistern).
  • the solid composition may be held under the rim of a toilet, in a suitable holder, for intermittent contact of the solid material with flush water.
  • Solid lavatory cleansing compositions typically comprise a surfactant component, generally together with one or more fillers or builders (e.g. inorganic salts such as sodium sulphate, sodium chloride etc.). Commonly, such compositions also contain a dyestuff and, frequently, a dissolution retardant material such as a hydrophobic material, difficultly soluble material or a gum The dissolution retardant is of particular importance when the solid composition is to be formulated as a free ⁇ standing block for immersion in a lavatory cistern.
  • a surfactant component generally together with one or more fillers or builders (e.g. inorganic salts such as sodium sulphate, sodium chloride etc.).
