ABSTRACT:
The invention relates to a process for preparing microcapsules in a liquid vehicle, allowing to microencapsulate both water soluble and water insoluble substances, using either ionic or non-ionic systems, in which the membrane enclosing the core of the microcapsules is formed by a polymer selected from the group of the phthalates, and more particularly by hydroxypropylmethylcellulose phthalate.
