Paul-

Right from Sigma at
www.sigmaaldrich.com/etc/medialib/docs/Sigma/.../t8532pis.pdf

It's on the first page of the pdf that some commercial instances have 
H2O2 added at .22%.

Also, they mention that Triton is a UV  (about 280nm range) absorber, if 
I'm reading it right.  They make a variation that deals with that

Might want to read :
www.sigmaaldrich.com/etc/medialib/docs/Sigma/.../pd1bul.pdf  also.

AND, (too funny to pass) the NIH talks about reaction with horseradish.  
But, read the short article further because it deals with peroxides 
forming when Triton solutions age.  It's at 
www.ncbi.nlm.nih.gov/pubmed/3993940.

It ends with, "These observations suggest the need for appropriate 
precautions when biologically active substances vulnerable to attack by 
peroxides are incubated with Triton X-100 either for their 
solubilization from biomembranes or for other processing."

This all got me wondering if other surfactants had similar issues you 
should be aware.
