Well, perhaps my inquiry to Anatrace for such a resource (wiki?) will work 
out. It was suggested to me that I thus inquire by somebody on this list. 
They probably have a lot of data which they have not published anywhere, for 
whatever reason. Hope that won't scoop you, or perhaps you would be willing 
to comtribute your work so far, and they might pick up some of the data 
entry load?

I have found Bob Laughlin's book 'The Aqueous Phase Behavior of Surfactants' 
to be a useful resource on detergents.  It has several relevant phase 
diagrams. Heavy on the P. Chem.

Then there is the mother of all info in the area "Critical micelle 
concentrations of aqueous surfactant systems" a handbook by Mukerjee and - 
you guessed it - Mysels, published in 1971 by the National Bureau of 
Standards.  No longer in print, it covers the lit from 1926 to the 
mid-sixties.  A lot of useful info in it (>5,000 records) including effect 
of salt, pH and other additives on CMC values.

We have converted the contents of the M&M handbook into a searchable 
relational database called the Critical Micelle Concentration Database 
(CMCD).  The intent was to update it with the latest info on the more 
commonly used detergents and to post it on the web.  However, this is a lot 
of work and requires funding.  Alas funding for databases is virtually 
impossible to get.  We will labor away at it in our 'spare time' and make 
what we have available for general use as soon as it is 'presentable'. 
Don't hold breath.

Hi,

The only published compendium on detergents still available (to my
knowledge) is http://www.merckbiosciences.co.uk/docs/docs/LIT/CB0068_M.pdf.
No phase diagrams though.
