INCI Name: Diisopropyl Adipate
Product Code: 2307
CAS #: 6938-94-9
EINECS: 230-072-0
Brand: HallStar®

HallStar® DIPA is a multifunctional (solvent for aromatic oils, coupler, emollient, lubricant, plasticizer) synthetically produced diester of isopropyl alcohol and adipic acid. It is a non-occlusive, non-oily, light emollient with excellent spreading properties. Used in bath oils, it delivers a soft feel to skin. In sunscreens, it solubilizes solid organic UV filters and its relatively high polarity may assist with Avobenzone photostabilization. Recommended use level: 0.1%-25%, depending upon application (lower end as a plasticizer, higher as an emollient, sunscreen solvent or hydro-alcoholic coupler, high end as a bath oil additive).
