Water-swellable particulate absorbents have improved dispersibility in blood by surface-treatment with a hydrocarbon compound which is an aliphatic hydrocarbon or a substantially nonionic derivative thereof which is non-volatile and has a melting point below 35 DEG C, or is a C12-C18 alkyl trimethylammonium halide. Examples of suitable aliphatic hydrocarbons are n-dodecane, n-hexadecane; n-heptadecane and n-octadecane. Preferred derivatives are fatty alcohols, fatty acids and fatty acid esters.
