In this investigation, PSf/vanillin microcapsules containing
vanillin as perfume, and prepared by phase inversion precipitation
technique, were obtained and analysed with the following purposes:
to prove the capability to incorporate hydrophilic perfumes,
to investigate their encapsulation capacity, to determine their suitability
for a long lasting perfume release and to examine the effect
of the water quality in their release behaviour. In addition, a comparison
between PSf/vanillin macro and microcapsules was also
included.
