Diisopropyl Adipate (DIPA)

Diisopropyl Adipate, also known as DIPA or diisopropyl hexanedioate, is a diester formed from adipic acid and isopropyl alcohol.  Its chemical formula is C₁₂H₂₂O₄, with a molecular weight of approximately 230.3 g/mol and CAS Number 6938-94-9.

It appears as a colorless to light yellow, clear, low-viscosity liquid at room temperature. DIPA is insoluble in water but highly soluble in common organic solvents such as ethanol and acetone.

As a multifunctional ingredient, Diisopropyl Adipate functions primarily as an emollient, solvent, skin-conditioning agent, and plasticizer.  It is prized for its excellent spreadability, ability to reduce tackiness, and compatibility with a wide range of cosmetic ingredients.
