  • Patent number: 6177396
    Abstract: The use of a stabiliser comprising a hydrophilic polymeric chain of more than four hydrophilic monomer groups and/or having a mass greater than 300 amu, linked at one end to a hydrocarbon-soluble hydrophobic group to reduce or prevent the flocculation of systems comprising a flocculable surfactant and a liquid medium which is capable of flocculating the surfactant and in which the stabiliser is capable of existing as a micellar solution at a concentration of at least 1% by weight.
