Background: Pastes are semisolid stiff preparations containing a high proportion of finely powdered material.
Powders such as zinc oxide, titanium dioxide, starch, kaolin or talc are incorporated in high concentrations into a preferably lipophilic, greasy vehicle.
Conclusions: We conclude that the classical two-phase pastes such as the zinc oxide pastes have no absorptive features.
