Dragonox® 901 is a bleaching agent and disproportionation catalyst for rosin esters and tall oil rosins. It functions as both the primary antioxidant and the secondary antioxidant, as it has the efficacies of both free radical termination and hydroperoxide decomposition. This product acts as a rosin disproportionation catalyst to transform the unsaturated conjugated double bonds of abietic type acid, which is susceptible to being oxidative, into dehydroabietic acid, which is stable.
