PROCEDIMIENTO PARA ENDURECER MICROCAPSULAS.

摘要

In a process for producing microcapsules which comprises microencapsulating hydrophobic oil droplets by complex coacervation using at least two hydrophilic colloids having opposite electric charges and being ionizable in water with at least one of the colloids being gellable, the improvement comprising hardening the coacervate wall by the presence of an oxidation product of a polysaccharide as a hardening agent and adjusting the pH.
