Laureth-10 is a polyethylene glycol ether of lauryl alcohol used as a nonionic surfactant, emulsifier, and solubilizer in cosmetic and skincare formulations. It helps blend oil and water phases and disperse otherwise insoluble ingredients.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Uncommon | More likely in rinse-off or high-concentration products and on compromised skin barriers. |
| Eye irritation | Uncommon | Can occur on direct contact, particularly in cleansers and shampoos. |
| Contact dermatitis / allergic sensitization | Rare | Laureth-class surfactants are infrequent sensitizers but reactions have been reported. |
| Dryness or barrier disruption with repeated use | Rare | Associated with surfactant action stripping skin lipids over time. |
| Concern over 1,4-dioxane trace contamination | Very rare | A byproduct of ethoxylation; controlled by purification, not an inherent effect of the ingredient. |
