A Question for the Chemically Inclined

I recently bought new shampoo, and in my usual morning funk, I happened to read the bottle this morning. I noticed that it claims to contain "New Amino Proteins." I thought to myself, "Self, are not all proteins 'amino' proteins?" So I went to the company's website to try to shed some light on the situation...no luck. If anyone can enlighten me on the subject, I'd appreciate it.
