1909 Chem. Abstr. 3 394 Classification of Colloids... The physical aggregations..are divided into two classes suspensoids..and emulsoids, in which the particles are minute drops of liquid.
1913 Chem. Abstr. 7 2144 An experimental test for emulsoids lies in their coagulability to two liquid layers.
1925 J. Alexander Colloid Chem. (ed. 2) 27 The reversible colloids are therefore called emulsoids and the irreversible colloids suspensoids.
1938 Science 4 Mar. 212/1 Originally ‘emulsoids’ included coagula, jellies and emulsions, the term being based on the assumption that jellies are fine emulsions.
1956 J. S. Anderson tr. H. Remy Treat. Inorg. Chem. II. xvi. 686 Colloidal emulsions are called emulsoids. [Note] The terms ‘emulsoid’ and ‘suspensoid’ are often applied also to the sols of lyophilic and lyophobic colloids, respectively, without regard to the state of aggregation of the disperse phase.
