Proteinaceous materials have a great deal of advantages in cosmetic products like Aion/Nai. I also run many of the ingredients through my fancy homogenizer which definitely effect the protein texture and its ability to penetrate the skin. Here are somethings I learnt form the cosmetic and dermatology papers I have been reading.
Contain amino acids
Quickly/readily bind to the stratum corneum
Some proteins promote other proteins proliferation - There are relationships and dependencies between Keratin and Collagen (which are types of proteins)
Substantive film-former, Gives the lather increased density; protein is polymeric!
Here is a good paper on the subject (behind a paywall)
