PEG-23 OLEATE.

Valuable CAS 9004-96-0 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-23 Oleate is a versatile polyethylene glycol fatty acid ester, meticulously designed to function as an emulsifier, surfactant, and skin conditioning agent. Its amphiphilic structure enables the stabilization of oil-in-water mixtures while contributing to skin softness and a clean feel.

Summary

Emollient Emulsifying Surfactant/Cleansing

Science

Mechanism of Action

This compound primarily functions as an emulsifying agent due to its unique molecular architecture, which incorporates both lipophilic and hydrophilic segments. This dual nature allows it to effectively reduce interfacial tension between immiscible phases, such as oil and water, facilitating the formation and stability of finely dispersed emulsions in formulations. Additionally, it acts as an emollient, imparting a desirable smoothness and softness to the skin.

Stability

Polyethylene glycols, including PEG-23 Oleate, are generally well-tolerated by the skin and exhibit robust stability, often not requiring additional preservation due to their low microbiological sensitivity. The ingredient's low free acid content further enhances its compatibility with sensitive formulation components.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has broadly concluded that PEG fatty acid esters, including those similar to PEG-23 Oleate, are safe for cosmetic use when formulated to be non-irritating. However, it is a critical restriction that PEG compounds and their derivatives should not be applied to damaged or compromised skin, as instances of sensitization and nephrotoxicity have been observed in burn patients treated with PEG-based creams. The FDA also recognizes PEG Oleate (which includes PEG-23 Oleate) as a secondary direct food additive for specific uses.
