Government of Bengal Department of Industries Bulletin No. 64 on the Part Played by Individual Fatty Acid Soaps in the Development of Optimum Detergency in Washing Soap

This is the point in the history of the theories of detergency which marks the unanimous departure from the alkali theory" of detergent action. [...] The stability is due to the fact that by further adsortion of the negative OH ion the net charge is increased on the surface of the dirt particles. [...] The gel theory requires little solubility of the cleansing medium in the adjoining phases the orientation theory demands a polar character in the cleansing medium the greater the polar difference the less soluble the substance. [...].'he practical attainment of th:i maximum detergency according to nove factors will he dependant primarily on (a) proper compounof stocks to get the balance between the factors involved (b) and Er on the control of the ultimate composition which can he secured pry the non-elimination of any constituent in the niger and making the soap by the grained process by which the entire stock is convert [...] From a calculation of the amounts of each fatty acid in the respetive oils making up the charger the total percentages of the fatty acids present in the final soap are given in the following table :— No.
