Abstract:
The object of the present invention is an injectable sterile aqueous formulation, ready-to-use, resorbable, used for aesthetic purposes as a particulate, cohesive, viscoelastic gel comprising i) crosslinked hyaluronic acid, or one of its salts, at a concentration of between 1% and 4% (mass/volume); the crosslinking carried out providing the possibility of obtaining a gel based on crosslinked hyaluronic acid with a so-called cohesive structure, and ii) hydroxyapatite, at a concentration of between 5% and 60% (mass/volume), said hydroxyapatite being in the form of particles with an average size of less than or equal to 200 μm; said injectable sterile aqueous formulation having viscoelastic properties such that tan δ at the frequency of 1 Hz is less than or equal to 0.60.

Claim (Index 17):
A method for making an injectable sterile aqueous formulation used for aesthetic purposes comprising the steps:\n a) preparing a first mixture comprising at least 1% to 4% by weight of crosslinked hyaluronic acid, or a salt thereof, by forming covalent bonds between the chains of the hyaluronic acid using bi- or poly-functional molecules to provide a crosslinked hyaluronic acid with a cohesive structure, b) purifying the first mixture, c) adding hydroxyapatite to the purified first mixture from step b) at a concentration of between 5% and 60% (mass/volume) and dispersing the hydroxyapatite homogeneously in the purified first mixture comprising crosslinked hyaluronic acid to form a gel product, d) converting the gel product obtained in step c) into a ready-to-use form, and e) sterilizing the gel product in a ready-to-use form in humid heat.
