A Personal Cleansing Composition

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.

Specification

FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See Section 10 and Rule 13) A PERSONAL CLEANSING COMPOSITION HINDUSTAN UNILEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 and having its registered office at 165/166, Backbay Reclamation, Mumbai -400 020, Maharashtra, India The following specification particularly describes the invention and the manner in which it is to be performed. Technical Field 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. Background of the invention 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 like 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 like bars when large number of people use the same bar one after the other. Such cleansing compositions have been formulated with detergent actives for providing the cleansing action. Popular 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, non-ionic, amphoteric and zwitterionic classes. All of the above classes have been included in persona! 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), sorbiton mono stearate, sorbiton mono oleate, ethoxylated SLES, Cetyl trimethyl ammonium halide among a host of other surfactants, many of which are commercially available under various brand names. Many of the above mentioned soaps and synthetic surfactants are expensive. It is believed that the surfactants are not effectively utilised 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. Certain highly absorbent materials like clay e.g. bentonite, attapulgite, kaolinite etc which are known to absorb oils have been used in cleansing compositions, but have had limited usefulness when incorporated in personal cleansing compositions. There has been further work on functionalising particulate material. Examples of design and synthesis of such particles using the above strategy are described in a review by Perro et al, J. Material Chem., 2005, 15, p3745-3760. One of the approaches used in the past is disclosed in US4715986 (Th. Goldschmidt AG, 1987) which describes particles for stabilizing or destabilizing emulsions of a size less than 100 microns, comprising fragments having on one side thereof hydrophilic group and on the other side thereof hydrophobic groups such that the hydrophilic and the hydrophobic groups are anisotropically distributed in a non-statistical manner. One of the methods for obtaining such fragments is by communion of hollow microspheres. In all the methods that are described, 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. In view of the limitations in the prior art, 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 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. Summary of the invention According to the present invention there is provided a liquid or soft-solid personal cleansing composition comprising
