  • Patent number: 12637569
    Abstract: A crosslinkable silicone elastomer composition is described that includes a heat-resistant additive. In particular, a crosslinkable silicone elastomer composition is described that includes a heat-resistant additive that is cerium (IV) neodecanoate.
    Type: Grant
    Filed: July 29, 2021
    Date of Patent: May 26, 2026
    Assignee: ELKEM SILICONES FRANCE SAS
    Inventors: Gérald Guichard, Christian Maliverney, Arnaud Ponce
  • Publication number: 20250296751
    Abstract: An article suitable for food contact includes a first substrate and a second substrate which are joined by an adhesive, said first substrate including a support coated with a silicone coating suitable for food contact, said adhesive being inserted between the two substrates and being in contact with the silicone coating of said first substrate. Said adhesive is a structural silicone adhesive suitable for food contact and obtained by crosslinking a silicone composition which is crosslinkable by a polyaddition reaction.

  • Patent number: 5688902
    Abstract: Process for the preparation of polyimides or of their polypeptide hydrolysates which are at least 80% biodegradable, by thermal polycondensation of at least one amino acid, optionally followed by hydrolysis, the thermal polycondensation step being carried out in the presence of at least one "acid catalyst" chosen fromsulphuric, nitric, phosphorous, sulphurous, hydrofluoric, silicic and sulphonic acids, organic sulphonic acids containing less than 50 carbon atoms, amino acids bearing a non-carboxyl strong acid function, organic phosphonic acids, organic carboxylic acids having a pK.sub.

  • Patent number: 5643863
    Abstract: Detergency builder/cobuilder preformulations, for improvedly stable/biodegradable detergent compositions, comprise intimate admixture of at least one polyimide polymer and at least one silicate, advantageously in the form of cogranulates thereof, said at least one polyimide polymer generating at least one biodegradable water-soluble polypeptide species when contacted with an aqueous medium having a non-alkaline pH.

  • Patent number: 5616547
    Abstract: Environmentally improved, storage-stable detergent compositions, having good efficacy in terms of both primary and secondary detergency, contain a surfactant and an in situ, wash water-hydrolyzable polyimide biopolymer, such polyimide biopolymer having a COO.sup.- charge density ranging from 0 to 5.times.10.sup.-4 mol/g thereof and the at least partially biodegradable polypeptide detergent builder hydrolysate thereof having a COO.sup.- charge density of at least 10.sup.-3 mol/g thereof.

  • Patent number: 5520842
    Abstract: Improvedly storage-stable, solid, particulate detergent compositions include a detergency surfactant and a builder therefor, the builder comprising at least one storage-stable, substantially non-hygroscopic, at least partially water-insoluble biodegradable polycarboxylic polymer compatible therewith, for example at least partially comprising a water-insoluble inorganic salt thereof, e.g., a calcium or magnesium salt, or at least partially comprising a water-soluble/water-insoluble mixed salt thereof, e.g., a Na/Ca mixed salt.
