Abstract
The invention relates to a process for preparing soap free, sulphate free and grit free solid cleansing composition. The composition has pH resembling to skin pH which comprises ‘non-soap’, ‘non-sulphate’ anionic surfactants and hydrogenated triglyceride oil/s, and optionally, skin benefit agents and/or hair benefit agents. This is accomplished by a unique short and cost-effective process without using any emulsifier or plasticizer. The process entails synthesizing sodium O-acyl isethionates by reacting fatty acid chloride with dry sodium methyl isethionate and sodium isethionate in a sequential manner followed by addition of hydrogenated triglyceride oil. The hot homogeneous paste of sodium O-acyl isethionates and vegetable oils is then flaked. The flakes are then kneaded in a sigma blender where other optional ingredients are mixed. The mass thus obtained is then further refined on a triple roll mill and plodded/extruded into billets or noodles.
