Absorption Bases This course of bases may be divided into two teams: the 1st team consisting of bases that permit the incorporation of aqueous options With all the formation of a water-in-oil emulsion (Hydrophilic Petrolatum and Lanolin), and the 2nd group consisting of h2o-in-oil emulsions that allow the incorporation of further quantities of aqueous methods (Lanolin). Absorption bases are handy also as emollients.
