Propylene glycol citrate

Propylene glycol citrate (CAS 85252-24-0) is a monoester of citric acid and propylene glycol used as an emulsifier, acidulant, and chelating agent in food, cosmetic, and pharmaceutical formulations.

Where is Propylene glycol citrate used?

• Food manufacturing: emulsifier and acidulant
• Dressings, sauces and processed foods: fat dispersion with pH control
• Personal care: stabilises oil-in-water emulsions in creams and lotions
• Pharmaceutical topicals: buffering agent maintaining target pH
• Beverages and flavours: carries acidic flavour profiles with greater stability than free citric acid
• Its ester structure provides hydrophilic and lipophilic character, stabilising emulsions and controlling pH in complex matrices.

Good to know: Food-grade material conforms to purity standards such as FCC or USP.
