PEG-15 STEARATE
Safety score · 0–100
Good
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A mid-high degree PEG stearate with 15 moles of EO, serving as a versatile O/W emulsifier with moderate skin compatibility.
PEG-15 Stearate is the polyethylene glycol (15 mol EO average) ester of stearic acid. The moderate-to-high ethoxylation gives it an HLB of approximately 15, making it a capable O/W emulsifier. It is listed in the EU Cosmetics Regulation without restriction and is considered safe for use in both rinse-off and leave-on cosmetic products. The PEG chain length reduces the irritant potential of stearic acid, though residual EO and 1,4-dioxane must remain within SCCS-recommended limits.
Skin benefits
- O/W emulsifier for lotions and creams
- Conditions and smooths skin
- Good balance of efficacy and mildness
Known concerns
- Potential trace EO/1,4-dioxane contamination from manufacturing
