About
A low-viscosity diester solvent — dry feel, often used as a silicone alternative.
Diisobutyl glutarate (CAS 71195-64-7) is the diisobutyl diester of glutaric acid. Industrially it has been used as a "green" solvent with low volatility and good dissolving power for resins and oils. In cosmetics it appears as a silicone alternative in products seeking a dry, slip-forward feel. Industrial safety data is reasonable, but cosmetic-specific CIR/SCCS review is limited. Skin irritation in standard patch panels is low at typical use levels. Score adjusted down from prior 85 pending broader cosmetic-specific evidence.
