The average length of the ethylenglycol chain is different, resulting in  
different properties (cmc, \bar{m}, Kraft point). Remember that Tritons  
are industrial detergents, that is wild mixtures of related compounds. For  
crystallisation I'd prefer detergents with defined structure, e.g. C12E8  
or the like.

Some detergent properties you can get from

pages of manufacturers like Anatrace.
