Stability
As an ester derivative of sorbic acid, Isopropyl Sorbate demonstrates enhanced preservative effectiveness within acidic formulations, specifically performing optimally within a pH range of 2.0 to 6.5. This mirrors the activity profile of sorbic acid and potassium sorbate.
Safety
Safety Profile
Comprehensive safety assessments by organizations such as CIR or SCCS are not available for Isopropyl Sorbate. General investigations into sorbic acid alkyl esters, including isopropyl sorbate, indicate varying toxicological and antimicrobial profiles compared to sorbic acid and its potassium salt.
