Abstract:
1. A dried product obtained by a method consisting essentially of: a) mixing a solid hyaluronic acid or a salt thereof with a solid chondroitin sulphate or a salt thereof at room temperature to form a solid mixture, b) forming an aqueous solution of said solid mixture at room temperature, and c) atomizing the resulting aqueous solution to form a dried product, wherein the hyaluronic acid or a salt thereof has an average molecular weight greater than 1,000,000 Daltons, and the chondroitin sulphate or a salt thereof has an average molecular weight from 5,000 to 50,000 Daltons, wherein an aqueous solution of the dried product has a viscosity lower than an aqueous solution of the hyaluronic acid or a salt thereof and the chondroitin sulphate or a salt thereof, and wherein an aqueous solution of the dried product at a concentration of 10 mg/mL has a conductivity lower than an aqueous solution of a mixture of the hyaluronic acid or a salt thereof and the chondroitin sulphate or a salt thereof at a concentration of 10 mg/mL.
