OLETH-11.

Valuable CAS 9004-98-2 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

OLETH-11 is a non-ionic surfactant specifically engineered from oleyl alcohol and ethylene oxide. Its primary function in skincare is to facilitate the stable integration of oil and water phases, acting as a highly effective emulsifier and solubilizer. Beyond its blending capabilities, it aids in cleansing processes and can enhance the absorption of other ingredients into the skin.

Science

Mechanism of Action

As a surfactant, OLETH-11 significantly lowers the surface tension between immiscible substances, enabling oil and water components to homogenize into stable emulsions. This action also allows it to effectively bind with and suspend lipophilic impurities, facilitating their removal from the skin and hair during cleansing. Additionally, OLETH-11 can transiently modulate the skin barrier, potentially augmenting the transdermal delivery of other active compounds. It also contributes to a consistent product texture and may provide mild hydrating benefits.

Stability

The water solubility of OLETH-11, characteristic of Oleth ingredients, generally correlates with its ethylene oxide content. While precise pH stability data for OLETH-11 is not available, related Oleth compounds demonstrate sensitivity and potential hydrolysis at high pH levels. For optimal stability, storage should be in a tightly sealed container, in a dry, well-ventilated environment, protected from moisture and air, and away from incompatible materials.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed OLETH-11's safety under current practices of use, basing its assessment on evaluations of oleyl alcohol and polyethylene glycol (PEG). It is noted that OLETH-11 may induce mild to moderate eye and skin irritation and can increase the penetration of other substances. A crucial safety caveat, derived from PEG assessments, advises against its use on damaged or compromised skin, due to observations of kidney effects in burn patients treated with PEG-based ointments. Trace amounts of 1,4-dioxane, a processing byproduct, may be present but can be controlled through purification processes. No specific SCCS opinion for OLETH-11 was found.
