Trideceth-6 Phosphate is a phosphate ester of ethoxylated tridecyl alcohol used as an emulsifier, surfactant, and emulsion stabilizer in cosmetic and skincare formulations. It helps blend oil and water phases and improves product texture and spreadability.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Uncommon | Possible transient redness or stinging, more likely in higher concentrations or on compromised skin. |
| Contact dermatitis / allergic sensitization | Rare | Rarely reported; ethoxylated surfactants may occasionally provoke allergic reactions. |
| Eye irritation | Uncommon | Surfactant properties can cause stinging or irritation upon ocular contact in rinse-off or leave-on products. |
| Concern over ethylene oxide/1,4-dioxane trace contaminants | Rare | As an ethoxylated ingredient, trace process impurities are theoretically possible but controlled by manufacturing purification. |
