Abstract:Hydrogels are polymeric matrices having minimal toxicity, elastomeric consistency and high permeability, making them useful for the controlled release of actives. These products have extensive applications in the cosmetic area as drug vehicles. In this work, hydrogels were prepared with concentrations of Polyvinylpyrrolidone (PVP, 7.5%wt), Polyethylene glycol (P.E.G., 3%wt) and agar (1%wt) containing pseudoboehmite, mandelic acid with essential oil of Palmarosa, Lavender, Geranium and/or Lemongrass, subjected … Show more
