About
Undeceth-8 is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.
UNDECETH-8 is a nonionic surfactant produced by ethoxylating undecyl alcohol (C11) with approximately 8 moles of ethylene oxide. The medium-chain alkyl group and intermediate EO degree provide a balanced surfactant profile with moderate irritation potential. EU Cosmetics Regulation lists this ingredient as permitted; it appears in Annex III with standard purity requirements. The shorter alkyl chain compared to C16/C18 analogues results in better skin compatibility overall, making this ingredient a preferred choice for gentle facial care formulations.
Skin benefits
- Gentle cleansing and emulsifying properties well-suited to facial care products
- Medium-chain alkyl profile provides favorable skin feel without excessive greasiness
Known concerns
- Residual ethylene oxide and 1,4-dioxane must be controlled per EU purity standards
- Standard skin tolerance precautions apply for leave-on use in sensitive individuals
