Resumo
Hydrogel is a gel formed by a three-dimensional network of hydrophilic
polymers that are used as advanced asset release systems with good biocompatibility.
The use of ionizing radiation to obtain hydrogels promotes cross-linking with
the concomitant sterilization of the hydrogels. Aiming at the release of the mandelic
acid (an active cosmetic), hydrogels were prepared using different concentration of
poly(N-vinyl-2-pyrrolidone) (PVP), poly(ethylene glycol) (PEG) and agar containing
nanoparticles of the pseudoboehmite, mandelic acid and Palmarosa and Rosa
Mosqueta oils nanoemulsions, submitted to irradiation dose of 25 kGy. Hydrogels
containing 7.5 wt% PVP showed better absorption, slip, odor results, and those with
10 wt% PVP were found to be inadequate. Nanoemulsions were characterized by
acidity, density and optical microscopy; hydrogels samples were put under isothermal
dehydration with air entrainment and dehydration was examined as a function of
time. The results showed that the composition of hydrogels is stable, and the increase
of the concentration of pseudoboehmite in hydrogels sample containing Palmarosa
oil suffers less dehydration and those containing the two oils showed an increase
in dehydration. The hydrogels obtained with 7.5 wt% of PVP and 3 wt% of pseudoboehmite,
Rosa Mosqueta vegetable oil and mandelic acid are most suitable to be
used in cosmetic products.
