Abstract
The aim of the present
investigation is to assess the possibility
of obtaining a biocompatible
material device which is able to deliver
oil-soluble fragrances in air
over a length of time. Aqueous
solutions of polyaspartamide functionalised
with glycidyl methacrylate
have been crosslinked through
gamma irradiation in the presence of
a lipophilic model fragrance, emulsified
prior to irradiation. Two
emulsification conditions have been
considered at two different concentrations
of both fragrance and surfactant
in water. Chemical hydrogels
have been obtained in correspondence
to two irradiation absorbed
doses and have been characterised
for their solubility properties and
swelling ability in water. Both static
and dynamic release experiments of
the fragrance in air have been performed
and the release behaviour
related to the hydrogel network
structure and its water retention
properties.
