Rosinox®, a high sulfur content bleaching agent for rosin and rosin ester dismutation

  • Rosin is composed of abietic acid which is prone to oxidation and cause crystallization
  • Abietic acid represents 25 to 40 weight % in tall oil rosin

  • Rosinox® allows a conversion of abietic acid into dehydroabietic acid thus leading to rosin bleaching
