Abstract
A soap-containing formulation capable of becoming transparent on working is subjected to shear between two mutually displaceable surfaces. A shear zone is formed in the formulation as the latter is entrained in the surfaces.
Claims5
The process of increasing the transparency of soap-containing detergent material in which shear sensitive soap-containing material is subjected to working by passing the material between two closely spaced mutually displaceable surfaces each having a pattern of cavities which overlap during movement of the surfaces so that the material moved between the surfaces traces a path through cavities alternately in each surface, whereby the bulk of the material passes through the shear zone in the material generated by displacement of the surfaces.
