The Theory of Emulsions and their Technical Treatment

Abstract

DR. CLAYTON'S book on “Emulsions” has been transformed completely since the first edition was issued in 1923. Indeed, an inspection of the references shows that a very large proportion of the contents of the present volume is of later date than the second edition issued in 1928. The present volume may therefore be considered in most of its aspects as if it were a new publication. The earlier chapters are naturally devoted to the fundamental principles of surface-phenomena, including air-liquid and liquid-liquid interfaces, which play so large a part in the production and stabilization of emulsions. Since water-in-oil emulsions are not formed, and stable emulsions of pure oil-in-water are limited to particles of the order of 10~5 cm. and to a maximum concentration of 1 in 10,000, the formation of emulsions depends on the presence of an emulsifying agent. These were formerly hydrophilic colloid such as gelatine; but in more recent years sulphates and sulphonates and sulphinates of known structure, and bases such as triethanolamine, N(CH2.CH2.OH)3, have been used extensively.
