Diisopropyl adipate is an alternative plasticizer and a TRPA1 activator. Diisopropyl adipate activates TRPA1 and enhances FITC-induced contact hypersensitivity (CHS).Diisopropyl adipate also serves as an ingredient in cosmetics and drug formulations topically applied to the skin. Diisopropyl adipate can be used as an excipient, such as emollients, plasticizers. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs.
