Frequently Asked Questions (FAQs)

What is Itaconic Acid?

Itaconic Acid is an unsaturated dicarboxylic acid with formula C₅H₆O₄ and CAS 97-65-4, used as a bio-monomer. It’s a white powder that copolymerizes for hydrophilic polymers and chelators in detergents.

How is Itaconic Acid used in superabsorbents?

Incorporate 5-10% with sodium acrylate in polymerization; it enhances cross-linking for higher swell ratios in absorbent cores.

Is Itaconic Acid safe for food-contact applications?

Yes, it’s FDA GRAS for indirect additives in polymers up to 10%, with low migration and no toxicity concerns.

What is the shelf life of Itaconic Acid?

Stored in sealed, dry conditions below 30°C, it remains stable for 2-3 years, with no degradation or odor development.

Can Itaconic Acid replace maleic acid in formulations?

Itaconic Acid offers similar reactivity but better hydrophilicity at 1:1 ratios, ideal for water-soluble resins without adjustment.

Does Itaconic Acid affect polymer pH?

Its acidic pH (2.5-3.5) requires neutralization in neutral systems, but it buffers mildly in copolymers for stable emulsions.

What packaging options are available for Itaconic Acid?

We supply 25kg multi-layer bags, 50kg drums, and 1000kg supersacks, all lined for moisture protection.
