PURPOSE: Provided is a process for sizing paper comprising adding to a cellulosic suspension an aqueous composition containing aggregates comprising a sizing agent, whereby the composition is formed by mixing in any order, an aqueous solution of a coagulation agent and an aqueous dispersion comprising a sizing agent wherein the zeta potential of the composition is less than 20 mV. CONSTITUTION: In a process for sizing paper comprising providing an aqueous suspension comprising cellulosic fibers, dewatering said aqueous suspension thereby forming a paper web, it comprises adding to the cellulosic suspension an aqueous composition comprising aggregates comprising a sizing agent. The composition is obtainable by mixing in any order prior to the addition to the aqueous suspension, (i) an aqueous solution comprising at least one coagulation agent, and (ii) an aqueous dispersion comprising a sizing agent, wherein the zeta potential of the composition is less than 20 mV.
