Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has classified data for PEG-3 Isostearate as 'insufficient.' While a broader group of chemically related 'PEG Stearates' (including PEG-2, -8, -40, -50, and -100 Stearates) were deemed safe up to 25 percent and showed no evidence of irritation or sensitization in clinical assessments, specific safety data directly pertaining to PEG-3 Isostearate itself is limited or not available in the provided research for a conclusive evaluation.
