Safety Profile
Direct safety assessments by key regulatory bodies such as the Cosmetic Ingredient Review (CIR), Scientific Committee on Consumer Safety (SCCS), or FDA have not been reported for Isopropyl 3-Methylthiobutyrate. A related compound, Isobutyl 3-methylthiobutyrate, was evaluated by JECFA in 2007 and found to pose no safety concern when used as a flavoring agent at current intake levels; however, this assessment does not directly translate to topical dermal safety for the current ingredient.

Verdict
With a lack of dedicated clinical studies and direct regulatory safety assessments for its use in skincare, its dermatological utility and safety profile remain largely underexplored.
