Definitions

  • the present invention relates to a cleaning composition, and a liquid cleaning composition adapted for direct application to fabrics or hard surfaces.
  • Such cleaning composition contains a first and second phase changing materials (PCMs) of different melting temperatures, a surfactant, and an organic solvent.
  • PCMs phase changing materials
  • Such cleaning composition is characterized by superior grease stain removal performance under cold water conditions.
  • the present invention relates to a cleaning composition which contains Phase Changing Materials (PCMs), which can improve the cold water grease removal performance of an existing detergent system by interfering with the grease crystallization process at lower washing temperatures.
  • PCMs Phase Changing Materials
  • the PCMs are substances having high fusion heat, which, upon undergoing a phase change, is capable of storing or releasing large amounts of energy per mass.
  • the PCMs will melt when the local temperature increases from a lower point to above the PCMs' melting point, and such melting will lead to energy storage by the PCMs.
  • the PCMs will freeze when the local temperature decreases from a higher point to below the PMC's melting point, and such freezing will lead to energy release by the PCMs.
  • Such energy storage or release by the PCMs function to provide a local temperature buffer to reduce grease crystallization and allow effective removal of the grease at lower washing temperatures.
  • One specific aspect of the present invention relates to a cleaning composition
  • a cleaning composition comprising:
  • a phase changing material having a first, higher melting temperature

  • PCM phase changing material
  • the weight ratio of said at least one organic solvent over said at least one surfactant is greater than 1:1, wherein said composition has a moisture content of less than 3 wt%.
  • the presence of two or more different PCMs having different melting temperatures provide a broader temperature buffer range for interfering with the crease crystallization and allow more effective cold water grease cleaning under different washing temperatures. Further, the relatively high solvent-to-surfactant ratio provides a facility for co-formulation of varied surfactant types and PCMs without phase separation. The low moisture or water content ensures permeation and fractionation of the grease substrate by the composition.
