  • SALT-RESISTANT EMULSIONS
    Publication number: 20130116342
    Abstract: The invention relates to methods of modulating the stability of emulsions, especially the stability of emulsions to flocculation and coalescence. The use of peptide emulsifiers comprising at least one side chain carboxylate group in preparing emulsions that are stable to flocculation or coalescence in the presence of salt is also described.
    Type: Application

    Applicant: PEPFACTANTS PTY LTD
    Inventor: Annette Faith Dexter
  • COALESCENCE OF EMULSIONS
    Publication number: 20130035266
    Abstract: The invention relates to methods of controlling the stability of emulsions to coalescence and phase separation. Use of chaotropic counterions to promote coalescence and/or phase separation of emulsions stabilized by ionic surfactants is described.

  • PEPTIDE NETWORKS
    Publication number: 20120046444
    Abstract: Methods of modulating interfacial characteristics in a self-assembled, force-transmitting peptide network at a fluid-fluid interface are disclosed. The methods involve exposing a peptide capable of participating in a self-assembled, force-transmitting peptide network, either before or after it interacts with other peptides to form the peptide network to a stimulus that alters the chemical and/or physical properties of the peptide. Use of such methods in applications such as emulsions and foams are also disclosed.
