Trideceth-10 is a polyethylene glycol ether of tridecyl alcohol used as a nonionic surfactant, emulsifier, and solubilizer in cosmetic formulations. It helps blend oil and water phases and stabilize emulsions rather than providing a direct skin treatment effect.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Uncommon | Possible with higher concentrations or sensitive skin. |
Contact dermatitis or allergic sensitization | Rare | Reported occasionally with ethoxylated surfactants. |
Eye irritation | Uncommon | On direct contact in rinse-off or leave-on products. |
Concern over 1,4-dioxane trace contamination | Rare | Byproduct of ethoxylation; minimized by purification during manufacturing. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
