According to the Calbiochem brochure "detergents" this seems to be the
case. Both Triton X-100 and NP-40 are nonaethylene glycol octylphenyl
ethers. Surprisingly, the same brochure gives different CMCs and molecular
weights for Triton X-100 and NP-40. The reason for this might be that
apparently neither Triton X-100 nor NP-40 are chemically pure substances
but mixtures of PEG octylphenyl ethers, with the PEG part not precisely
