Abstract

A process for manufacturing coloured speckles for use in washing powder involves in the following steps: (a) forming a molten mixture of surfactant and colourant; (b) solidifying the mixture, for example by spraying it onto a water-cooled rotating drum (15); (c) milling the solid material to particles of a suitable size for use as speckles; and (d) separating the desired particles by elutriation.
