Description
Itaconic acid (CAS 97-65-4, EC 202-599-6) is a bio-based dicarboxylic acid produced by fermentation of carbohydrates, also known as methylenesuccinic acid. It carries no E-code designation and is commercially available under both names across polymer, food, and personal care markets.
In plastics and polymer manufacturing, itaconic acid functions as a reactive monomer that introduces carboxylic functionality into acrylic and styrene-butadiene copolymer chains, improving adhesion and crosslinking density. In personal care formulations, it acts as a skin conditioner and pH modifier, while food-grade material serves as a mild acidulant and flavoring agent.
Itaconic acid is supplied as a white to light beige crystalline powder at 99%+ purity, meeting food-grade and technical-grade specifications including FCC compliance. It falls under REACH registration requirements for EU supply. Standard packaging formats include 25 kg bags, with bulk options available on request. HS code 29171990 applies for import classification.
