A solid porous surfactant body of low density, for example, a tablet, comprises a high level of surfactant: at least 60 wt% and preferably at least 75 wt%. Preferably a high level of anionic surfactant is present. Inorganic salts are preferably absent, or present only in small quantities. The body is typically in the form of an assembly of solid surfactant particles, for example, flakes, bonded together by means of heat and/or a binder. |
