Rosinox® is a bleaching agent and dismutation catalyst for rosin and rosin esters.

Rosinox® is a low-molecular-weight alkylphenol disulfide oligomer containing 31.5% sulfur.

Produced by Arkema Rotterdam and distributed by MLPC.

Rosinox®, a bleaching agent for the disproportionation of rosin and rosin esters:

• Abietic acid represents 25 to 40% by weight of tall oil rosin.
• Rosin is composed of abietic acid, which is susceptible to oxidation and crystallization.
• Rosinox® converts abietic acid into dehydroabietic acid and bleaches rosin.

Advantages and features of Rosinox® :

• Reduction of abietic acid content in rosin and rosin esters
• Increased dehydroabietic acid content in rosin and rosin esters
• Color reduction drosins and esters
• Similar behavior of Rosinox® whether in tall oil rosin or esterified or unesterified gum rosin.
• Antioxidant/stabilizer in rosin and ester processing
• Efficient even at low doses
• Easy to handle (past form)
• No handling of dusty powder
• Rosinox® is FDA-approved as an antioxidant/stabilizer in the processing of rosins and rosin esters for use as components in adhesives complying with FDA 21 CFR 175.105.
