Isopropyl citrate

Isopropyl citrate (CAS 39413-05-3), approved as E384 in food applications, is a citric acid ester used commercially as a chelating agent, emulsifier, and antioxidant stabilizer.

Where is Isopropyl citrate used?

• Edible oils, margarines and fat-based foods: extends shelf life
• Personal care: stabilizes oil phases in creams, lotions and lipstick bases
• Lubricants and metalworking fluids: chelant controlling metal contamination
• It binds metal ions that would otherwise catalyze oxidative degradation in fats, oils and formulated products.
• It sequesters pro-oxidant metals such as iron and copper, protecting flavor and color integrity.
• It acts as a synergist alongside primary antioxidants such as tocopherols.

Good to know: Food-grade material meets E384 regulatory specifications for permitted fat and oil applications; technical-grade supply serves industrial lubricant and metalworking uses where food compliance is not required.
