摘要:
The present invention generally relates to a modified hyaluronic acid (HA) and to a method for making same, more specifically to a (poly)glycerol-modified HA derivative prepared by grafting glycidol to HA. The present invention also relates to the use of the HA derivative for preparing a dermal filler composition, a hydrogel comprising cross-linked HA and the (poly)glycerol-modified HA derivative, and a method for preparing said hydrogel. Furthermore, the present invention relates to the use of the hydrogel as a cosmetic and/or aesthetic product, in particular as a dermal filler for tissue filling, replacing and/or augmenting.
摘要:
Method of preparing a composition comprising a crosslinked first polymer and a non-crosslinked second polymer, wherein the first and the second polymer are selected from a polysaccharide, and water, wherein the composition contains an anesthetic and/or anti-arrhythmic, comprising at least steps (S2) to (S5): (S2) crosslinking a mixture comprising the first polymer and water; (S3) subsequent to the crosslinking in step (S2), terminating the crosslinking; (S4) subjecting the product obtained after step (S3) to dialysis; (S5) blending the product obtained after step (S4) with a mixture comprising the second polymer and water, wherein the mixture comprises an anesthetic and/or anti-arrhythmic.
摘要:
The present invention generally relates to a mixing nozzle (12) for mixing at least two liquid compositions such as a first liquid composition and a second liquid composition. The mixing nozzle(10)is configured to be coupled to a body (11) of a multi-component application device(10), in particular to a body (11) of a two- component syringe assembly,for injection of a liquid composition, which body(11)is configured to separately store said at least two solutions. The present invention further relates to a multi-component application device(10)comprising said mixing nozzle (12) and to a kit comprising said mixing nozzle (12) or said application device (10). Furthermore, the present invention relates to a methodusing said application device or said kit, for examplefor replacing or filling a biological tissue or increasing the volume of a biological tissue.
摘要:
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.
摘要:
The present invention relates to a composition for the in vivo degradation of polysaccharide-containing fillers by radical degradation. The composition of the invention comprising at least one source of oxygen free radicals and at least one catalyst of oxygen free radical generation from the at least one source of oxygen free radicals. The present invention further relates to methods and uses of said composition for filler correction or reversal.
摘要:
The present invention relates to polysaccharide soft tissue fillers comprising heparosan and processes for their preparation. The polysaccharide soft tissue fillers of the present invention are advantageously used in therapeutic or cosmetic applications such as for the filling of wrinkles.
