So here's a blend that is 13% surfactant:

Apparently there's blends intended for use in water that are more or less just diluted with water, but they aren't the usual mix either.

Can you get pure glyphosphate? Yes, but it requires a license. It comes in about a 50/50 mixture with water usually.
It is much too difficult to distribute the pure substance in such small quantities so it is diluted with water to varying degrees (down to a few percent concentration) for safety, accuracy, and to avoid burning plants with unavoidable variations in application.
A small amount of a attractant is also added so the chemical better applies to leaves and doesn't just bead up and drip off onto the soil.
