Web• The polymer swells to form a hydrated matrix layer (hydrogel) (Figure 1). Due to the crosslinked nature of the polymers, the hydrogel is not comprised of single entangled chains of polymers (as is the case with linear polymers) but is comprised of discrete microgels made up of many polymer particles in which the drug is dispersed. WebPenetration data show that these polymers are more efficient than stearyl alcohol at gelling cyclomethicone. Efficiency depends on the level of polymer used and the desired penetration value. In this study, the higher the molecular weight of the polymer, the harder the resulting gel, with the 500 MW polyethylene having the highest
