need help with kitchen sink science - chemical economics

In an attempt to determine a price/stuff ratio, I picked up a 7.5
pound jar of sodium lauryl sulfate (CAS #151-21-3) solution. It's a
Proctor & Gamble product, bought retail, so a comparison to shampoo
ought to determine how much one pays for the active contents versus
how much one pays for faux-alpine scenery on the packaging.

What I need is a simple way to determine the concentration ratios of
this jar and a bottle of consumer shampoo. Simple physical properties
that can be determined in a household kitchen would be best, but if
worst comes to worst, I suppose I could trundle out to the UC and
see if I can weasel something.

Any suggestions?
