ISOPROPYL CITRATE.

Valuable CAS 1321-57-9 / 39413-05-3 / PLASTICISER, SOLVENT

Isopropyl Citrate is a multifunctional ester primarily used in precision skincare formulations to enhance product stability and texture. It acts as an antioxidant and sequestrant, protecting sensitive ingredients from degradation, while also serving as a solvent and plasticiser to optimize the overall formula.

Antioxidant Sequestrant Solvent Plasticiser Emulsifier

Science

Within cosmetic formulations, Isopropyl Citrate functions by chelating metal ions, thereby preventing oxidative reactions and rancidity that can compromise product integrity and the efficacy of active ingredients. It also improves product texture by acting as a plasticiser, making formulations smoother, and as a solvent, aiding in the dissolution and uniform dispersion of other components. These actions indirectly benefit the skin by ensuring the delivery of stable and optimally formulated products.

Stability

Isopropyl Citrate exhibits solubility in both organic solvents, water, and ethanol, particularly when used in its mixture form. Its unique structure, derived from water-insoluble citric acid and oil-soluble isopropyl alcohol, enables it to dissolve effectively in oil. Specific optimal pH ranges for its intrinsic stability are not explicitly defined, though citrate buffers typically operate within a pH range of 3.0 to 6.2.
