Dear Veronica,
According to Andrew Wingham' final year research project; Synperonic N The Search for an Alternative(2000-2001), the critical micelle concentration (CMC) for Triton XL80N is 0.553 g/l which does fall between the suggested concentrations in Chemical Principles.

Wingham uses Triton XL80N in the first phase of the research but eliminates it based on its pH. This surfactant has a large pH range (4.03- 6.36) when used to wash both cotton and wool, and was therefore considered unsuitable for washing historic textiles. The cleaning properties were also considered to be poor to OK.

I hope this is of some help. Happy washing.

Dear Colleagues

Last year I attended  the cleaning workshop given by Dr. R. Wolbers
at the NATCC.
Following the information I could get Tritón XL-80N but only in a small
quantity
because Sigma here only works with investigation programs and dont sell
another quantity. Does anyone has  experience working with it? is  there a
specific
concentration for this surfactant or you can use the suggestion 0.5-1.0 g/l
(Chemical principles of Textile Conservation by Agnes Tymar-Dinah Eastop) ?
I principaly will use it for tapestries cleaning.

Thanks,
