 |
| Disproportionated Rosin |
 |
SYLVAROS DR-22 is a catalytically disproportionated rosin derived from high-purity tall oil rosin.
It is more uniform, higher in rosin acids, and lower in unsaponifiable material than disproportionated wood or gum rosin.
The disporportionation step converts abietic acid to the more oxidation-resistant dihydroabietic and dehydroabietic acid isomers. |
