发明名称 METHOD FOR THE PRODUCTION OF MICRO CAPSULES
摘要 A method for the production of micro capsules by atomizing an aqueous solution (1) containing 0.1-5 wt. % of at least one water-soluble polyanion to form liquid droplets. The liquid droplets thus obtained impinge upon a liquid film of an aqueous solution (2), containing: 0.1-5 wt. % calcium cations, 0.001-0.4 wt. % chitosane with a molecular weight of more than 40,000 g/mol, and/or 0.1-5 wt. % chitosane with a average molecular weight of 500-40,000 g/mol.
