Cècile Monteux has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polymer membrane and methods of manufacturing thereof
    Patent number: 11401390
    Abstract: This invention relates to a polymer membrane comprising a hydrogen bond donor polymer and a hydrogen bond acceptor polymer and to the use of such membrane as the shell of a capsule. The invention also relates to a method of manufacturing a polymer membrane comprising a step of contacting an aqueous phase comprising a first polymer, and an oil phase comprising a second different polymer; wherein one polymer is a hydrogen bond donor polymer and the other polymer is a hydrogen bond acceptor polymer. The invention also relates to a method of encapsulation comprising a step of manufacturing a polymer membrane.
    Type: Grant
    Filed: March 16, 2018
    Date of Patent: August 2, 2022

  • Method of encapsulating a liquid active
    Patent number: 10940336
    Abstract: A method of encapsulation of an active comprising (a) dispersing an active in an aqueous medium having a pH of less than 6; (b) causing the formation on this dispersed active of a polymer shell, the formation comprising the sequential deposition of a series of polymeric layers, each layer being capable of hydrogen bonding with the preceding layer; to form an aqueous slurry of active-containing capsules; characterised in that one of the first two layers is a polycarboxylic acid and that the first two to four layers taken together exhibit an interfacial compression dilation modulus of greater than 10 mN/m. The method allows the precise tailoring of polymeric shells, allowing capsules walls to be much thinner without a loss of strength. The technique is especially useful for the encapsulation of fragrances and flavours.
