  • Patent number: 10335512
    Abstract: The present invention relates to injectable dermal filler compositions in the form of a gel, comprising hyaluronic acid (HA), carboxymethyl cellulose (CMC) and, optionally, microparticles such as calcium hydroxyapatite (CaHAP) microparticles. The injectable dermal filler compositions have improved rheological properties while at the same time have low extrusion forces. The present invention further relates to a method for preparing such injectable dermal filler compositions and their use for cosmetic and therapeutic purposes.

  • Publication number: 20180177707
    Abstract: The invention relates to a method of preparing a composition, the composition comprising a crosslinked first polymer, optionally a second polymer, which may be crosslinked or non-crosslinked, and water, wherein the first and the second polymer are selected from a pollysaccharide, comprising at least steps (i) to (iv): (i) crosslinking a mixture comprising the first polymer and water; (ii) subsequent to the crosslinking in step (i), terminating the crosslinking; (iii) optionally blending the product obtained in step (ii) with the second polymer; (iv) subjecting the product obtained in step (iii) to dialysis.
