Abstract: A process for producing a liquid composition containing at least one active component and a diluent by mixing the active with diluent and/or liquid active to produce a liquid crystal mixture and incorporating diluent into it such that the mixture remains substantially homogeneous to produce a composition in which the concentration of active components is lower than the concentration of active components in the liquid crystal mixture. Novel apparatus for use in the process is also described.

Abstract: Agglomerated abrasive material suitable for use in liquid abrasive cleaning compositions comprises inorganic filler and a polymeric binding agent selected from polyalkylenes, copolymers of polyalkylenes with each other and copolymers of polyalkylenes with up to 30% by weight of monomers containing a carboxylic acid or ester group. These agglomerates can be prepared by a process in which a melt of inorganic filler in polymeric binding agent is formed and thereafter further inorganic filler is added to the melt to raise the weight ratio of inorganic filler to binding agent above a level at which the melt spontaneously crumbles.
