  Maybe hydrophobically modified Chitosan, @Pharma ‘s favorite ingredient might be in this category?

  Typical hydrophobically modified polymers are found amongst the carbomers and polyacrylates such as Carbopol Ultrez 21. Another one would be ethyl cellulose (often not considered as ‘modified’ due to a too high degree of lipophilic linkers)… it’s not a typical one, behaves differently, and has different uses and perks.

  I admit that I love chitosan. However, I haven’t come across hydrophobically modified one… and now I have to Google that :smiley: .
