Steareth-2 is a polyethylene glycol ether of stearyl alcohol used as a nonionic emulsifier and surfactant to blend oil and water phases in creams and lotions. It functions as a formulation/base ingredient rather than an active treatment.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Uncommon | Possible transient irritation, especially on sensitive or compromised skin. |
Allergic contact dermatitis | Rare | Sensitization to the emulsifier or impurities has been occasionally reported. |
1,4-dioxane impurity exposure | Rare | Ethoxylated ingredients may contain trace 1,4-dioxane, a byproduct of manufacturing that can be reduced by purification. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
