General description

Gum rosin is an exudate gum, which is extracted from pine trees. It consists of abiatic acid, palaustric acid and neoabetic acid.

Application

Gum rosin has been used:
  • for the preparation of testosome patches
  • to study its influence on the physical stability of concentrated oil in water emulsions
  • for the preparation of rosin nanoparticles containing hydrocortisone (HC)

Analysis Note

powder to solified mass or chunks, yellow to deep yellow

We have carried out the synthesis of side-chain rosin-ester-structured poly(ε-caprolactone) (PCL) through a combination of ring-opening polymerization and click chemistry. Rosin structures are shown to be effectively incorporated into each repeat unit of caprolactone. This simple and versatile methodology does
