Solution aqueuse homogene de chitosane injectable |
摘要 |
The present invention relates to a homogeneous aqueous solution of injectable chitosan containing a chitosan having a degree of acetylation lower than 20%, said solution containing between 0.1 and 3.5% by weight of chitosan, said solution presenting a pH lower than 6.2, and said aqueous solution being capable of forming crystalline particles of chitosan after injection. The present invention also relates to compounds containing such a homogeneous aqueous solution of chitosan. The invention also relates to such compounds for their use as dermatological or cosmetic compounds, or for their use as a medical device, advantageously as a bioresorbable implant. |
