Just a word of caution.  Most of us use NP-40 to mean Nonidet P40.  
This is basically the same as Triton X-100, except that it is a finer 
cut from the fractional distillation used in the production process.  
There is also a nonionic surfactant named Tergitol NP-40.  Almost 
no one uses it in biochemistry, but there is the possiblilty for 

I hope this helps.
