Abstract

A method of forming a polymeric coating on a detergent tablet containing an alkaline agent comprises applying to the tablet a continuum of an aqueous solution or suspension of a polymer having free acid groups, and evaporating water to leave the coating on the tablet. The solution/suspension is most preferably applied by passing the tablets relatively through a falling cascade /curtain) of the solution/suspension.
