Abstract
A process for preparing a suds controlling composition suitable for incorporation into laundry detergent products comprises absorbing into the pores of porous silica a sufficient amount of a surfactant-containing solution to ensure wetting of the porous silica, dispersing the porous silica having the surfactant-containing solution absorbed therein in a silicone oil and mixing the dispersion with a dispersing agent.
