PEG-100 Stearate
Commonly feared, low concern·Strong evidence
A PEG-based emulsifier that blends oils and water in formulas. It is a workhorse ingredient in stable emulsions and is approved for cosmetic use. Well tolerated.
The myth vs the evidence
Clean beauty brands often avoid PEGs, citing concerns about 1,4-dioxane contamination or their synthetic nature. PEG-100 Stearate is approved and graded safe by regulatory bodies. The published evidence does not support the fear.
