Definitions

  • 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 which have been used heretofore in such cleansing compositions.
  • the present invention more particularly relates to a cleansing composition in liquid, gel or cream formats.
  • Cleansing compositions in soft-solid or liquid formats have aesthetic appeal with consumers. These are often used for specialised applications like hand wash and face wash. These are particularly preferred for out-of-home applications such as during travel, at hotels and restaurants where people are more conscious of hygiene, as there is a possibility of contamination at the wash place with formats such as bars when large numbers of people use the same bar one after the other.
  • Such cleansing compositions have been formulated with detergent actives for providing the cleansing action.
  • detergent actives which have been used are soaps and synthetic surfactants. Soaps are salts of fatty acid of which alkali metal salts have been more commonly used. Of these, potassium soap has been more preferred in such soft solid or liquid cleansing compositions, since potassium soaps are more soluble in water than other soaps, thereby maintaining the liquid state in the formulation.
  • Synthetic surfactants are usually made from materials of petroleum origin. Synthetic surfactants are classified into anionic, cationic, nonionic, amphoteric and zwitterionic classes. All of the above classes have been included in personal cleansing compositions.
  • Popular synthetic surfactants include primary alcohol sulphates (PAS), alkylbenzene-sulphonates (LAS), sulphates of ethoxylated aliphatic alcohols containing 1-12 ethyleneoxy groups, sodium lauryl ethoxy sulphate (SLES), the reaction product of fatty acids esterified with isethionic acid and neutralised with alkali, alkyl betaines (e.g. cocobetaine), alkyl amidopropylbetaines (e.g.
  • coco amidopropyl betaine - CAPB coco amidopropyl betaine - CAPB
  • sorbiton monostearate sorbiton monooleate
  • ethoxylated SLES cetyl trimethyl ammonium halide among a host of other surfactants, many of which are commercially available under various brand names.
  • soaps and synthetic surfactants are expensive. It is believed that the surfactants are not effectively utilized, and there is scope for better utilisation, thereby reducing wastage and cost to both the manufacturers and the consumers. Further, conventional surfactants mentioned above are believed to be non-biodegradable, and therefore a burden to the environment. Thus, development of alternative surface active materials which are more environmentally friendly will be welcomed not only by the Governments but by the manufacturers and consumers at large. Conventional surfactants are also perceived by some consumers to harsh on the skin, leave an unpleasant feel on the skin after use and there are problems with ease of rinsing. Thus, there is a need for providing milder, more skin friendly and easily rinse able detergent actives in personal cleansing compositions.
  • precursor materials have homogeneous distribution of surface groups, e.g. silica, alumina, hollow microspheres, microgel, carbon and starch. Processes starting with asymmetric particles such as 1 :1 clays are not described.
  • the present inventors have been working on solving this problem of providing alternative materials having enhanced surface active properties. They have, during the course of their research, developed novel materials starting from 1 :1 or 2:1 :1 clays that give materials with enhanced oil removal properties and are therefore highly suitable for preparing liquid or soft solid personal cleaning compositions. Quite surprisingly, these materials could be prepared from inexpensive and widely available materials using simple processes, in high yield with the additional advantage that the processes are easy to scale up.
  • the prior art materials and process known to prepare them were found to suffer from lack of one or more of the above listed advantages.
  • one of the objects of the present invention is to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
  • Another object of the present invention is to provide a personal cleansing composition
  • a personal cleansing composition comprising a novel material which is an alternative to conventional surfactant which on the one hand has similar or superior properties compared to conventional surfactants with less of their disadvantages like low biodegradability, irritation to the skin and high cost.
  • Yet another object of the present invention is to provide for a personal cleansing composition that utilises a novel material which is an alternative to conventional surfactant which can be prepared using simple and easy to scale up process.
  • a liquid or soft- solid 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.

  • the treated particle used in the personal cleansing composition of the invention is believed to have the property of anisotropic hydrophobicity which is possibly the reason for providing the surface active property responsible for the cleansing action.
  • anisotropicity is meant that the particle has two spatially distinct exterior faces having distinct surface characteristics wherein one of the distinct exterior faces is relatively more hydrophilic and the other distinct exterior face is relatively more hydrophobic.
