  • the present invention generally relates to a cleaning composition for hard surfaces. More particularly, the invention relates to a novel hard surface cleaning formulation having superior cleaning ability which is free of
  • Powdered cleaning compositions consist mainly of builder or buffering salts such as phosphates, carbonates, and silicates and although such compositions may display good inorganic soil removal, they exhibit inferior cleaning performance on organic soils such as greasy/fatty/oily soils.
  • Liquid cleaning compositions on the other hand, have the great advantage that they can be applied to hard surfaces in neat or concentrated form so that a relatively high level of surfactant material is delivered directly to the soil. Moreover, it is a rather more straightforward task to incorporate high concentrations of anionic or nonionic surfactant in a liquid rather than a granular composition. For both of these reasons, therefore, liquid cleaning compositions have the potential to provide superior grease and oily soil removal over powdered cleaning compositions.
  • liquid cleaning compositions suffer a number of drawbacks which can limit their consumer acceptability.
  • they generally contain little or no detergency builder salts and consequently they tend to have poor cleaning performance on particulate soil and also lack effectiveness under varying water hardness levels.
  • they can suffer problems relating to homogeneity, clarity, and viscosity when used by consumers.
  • the higher in-use surfactant concentration necessary for improved grease soil removal causes further problems relating to extensive suds formation requiring frequent rinsing and wiping on behalf of the consumer.
  • a solution to the above-identified problems has involved the use of saturated and unsaturated terpenes, in combination with a polar solvent, in order to increase the cleaning effectiveness of the hard surface cleaner and control sudsing.
  • terpenes such as, for example, d-limonene
  • their price, as a raw material tends to fluctuate wildly.
