Yeah, Surf King meets all those parameters. This gets kinda techie but it explains all the products. http://www.fs.fed.us/r1/custer/projects/planning/weedwebdocs/feis_appendix_j_herbicide_efficacy.pdfsurf king is a penetrator. The degree that a product actually penetrates is a factor of its acidity and oil content. The oils help to break down the surface tension and the acidity helps to pass through the waxy cuticle and be absorbed into the plant membranes. BTW, no product can accurately claim 100% absorption into the leaf. It just doesn't work like that.
PS I still don't know where to buy the fucking stuff. The online forestry supply and ag business I have accounts with don't carry it. Guess I can shop around at some of the ag stores but don't have tons of time for that.
All feed stores in my town carry a lot of these surfactants, and that includes Tractor Supply Company. In fact, I bought the Red River 90 at a feed store. TSC has one called L100.
