dc.description.abstract© The Minerals, Metals & Materials Society 2020.Hydrogel is a gel formed by a three-dimensional network of hydrophilic polymers that are used as advanced asset release systems with good biocompatibil-ity. 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.
