Hydrogels are asset release systems. Hydrogels were prepared with concentrations of PVP (10w%, 7.5w% and 5w%), PEG (3w%) and agar (1w%) containing pseudoboehmite (1w%, 3w% and 5w%), mandelic acid and Palmarosa and Rosa Mosqueta oils nanoemulsions, submitted to irradiation doses of 25kGy. Hydrogels containing 7.5w% PVP showed better absorption, slip, odor results, and those with 10w% PVP, were found to be inadequate. Nanoemulsions were characterized by acidity, density and optical microscopy; hydrogels by isothermal dehydration with air entrainment and dehydration as a function of time. The results showed that the compositions are stable, and the increase of the concentration of pseudoboehmite the ones containing Palmarosa oil suffer less dehydration and those containing the two oils present an increase in the dehydration. The hydrogels obtained with 7.5w% of PVP, 3w% of pseudoboehmite, Rosa Mosqueta vegetable oil and mandelic acid were the most suitable for applications in cosmetic products.
