SOAPS AND PROTEINS 



again dominated by the soap of the lesser absolute gelation 

 capacity. 



These several experiments show, therefore, that in any soap 

 mixture it is the soap with the lower absolute gelation capacity 

 which gives the deciding character to the mixture. In trying 

 to account for this, it is of interest to point out that the simpler 

 soaps, or those lowest in any series, stand closer to the ordinary 

 " salts " of the physical chemists than do the more complex or 

 higher soaps. The lower soaps, as it were, " salt-out " the higher 

 ones as do the ordinary neutral salts when added to the soaps. 

 This matter will be discussed later. 1
