if this would be likely to irritate my skin due to containing sodium ammonium sulfates? I know I'm sensitive to sodium lauryl sulfates but not sure about the SAS
I would take a stab at a guess that a sulfate is a sulfate is a sulfate, so you probably don't want to mess with it. Especially given how expensive it is, I would hate for you to get it and then not be able to use it only to end up giving it away.
