Abstract (en)
[origin: WO2012013895A1] The present invention relates to positively charged particles consisting of a chitosan polyelectrolyte complex and of an anionic polymer, characterized in that the chitosan has a degree of acetylation (DA) in the range of 35 to 49 % and a mean molar mass by weight Mw in the range of 55 to 150 kg/mol, as well as to a method for preparing same.
