THE SYSTEM SOAP/X. COLLOID SOAPS IN OTHER 

 NON-AQUEOUS "SOLVENTS" 



It is of importance for the theory of the lyophilic soap colloids 

 in particular, and of lyophilic colloids in general, to see how much

further the composition of these systems may be broadened and 

 still yield the definitely colloid systems under discussion. The 

 soaps form admirable materials for such a study, for, as already 

 observed, they yield colloid systems not only with water arid the 

 various monatomic, diatomic and triatomic alcohols but also 

 with many other liquid " solvents." 



Some colloid systems of the general composition soap/x are 

 illustrated in Fig. 43. Here sodium stearate and sodium oleate
