C12-13 Pareth-23 is a polyethylene glycol ether of synthetic C12-C13 fatty alcohols used as a nonionic surfactant, emulsifier, and solubilizer in cosmetic formulations. It helps disperse oils and stabilize emulsions rather than providing a direct therapeutic effect.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Uncommon | Possible with leave-on products or high concentrations, particularly on compromised skin. |
Eye irritation | Uncommon | Can occur upon direct contact with eyes in rinse-off or cleansing products. |
Allergic contact dermatitis | Rare | Sensitization to ethoxylated surfactants is infrequently reported. |
Concern over 1,4-dioxane trace impurity | Very rare | A byproduct of ethoxylation; managed through manufacturing purification rather than a direct user side effect. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
