Abstract: This invention relates to a liquid or soft-solid personal cleansing composition that utilises the detergency properties of new materials which are more efficient, more inexpensive and are an environmentally friendly alternative to conventional soaps or synthetic surfactants. It more particularly relates to a cleansing composition in liquid, gel or cream formats. The present invention provides for a personal cleansing composition comprising (i) 1 to 50% of treated clay particles; and (ii) a cosmetically acceptable base; wherein said treated clay particles are asymmetric 1:1 or 2:1:1 clay particles having alternating tetrahedral and octahedral sheets terminating with a tetrahedral sheet at one external surface plane and an octahedral sheet at another external surface plane, with a fatty acid of carbon chain length 10 to 22 attached to coordinating cation on one of said exterior surface planes.

Abstract: This invention relates to particles with bipolar topospecific characteristics and process of preparation thereof. It is an object of the present invention is to provide a particle with bipolar topospecific characteristics with two spatially distinct regions on its surface having non-identical surface characteristics. It has been found that particles prepared by topospecific treatment of an asymmetric clay precursor with an organyl or an organoheteryl group attached to coordinating cations of one of the surface sheets, provides a particle with bipolar topospecific characteristics with two spatially distinct regions on its surface having non-identical surface characteristics.

Abstract: A particle with bipolar topospecific characteristics, whose precursor is an asymmetric 1:1 or 2:1:1 clay particle having alternating tetrahedral and octahedral sheets terminating with a tetrahedral sheet at one external surface plane and an octahedral sheet at another external surface plane, wherein a chemical group, having greater than 3 carbon atoms, and selected from an organyl or an organoheteryl chemical group, is attached to coordinating cations on the exterior side of one of the surface sheets.
