What Is Disodium Oleamido PEG-2 Sulfosuccinate?
Disodium Oleamido PEG-2 Sulfosuccinate is a mild surfactant derived from oleic acid, a fatty acid found naturally in oils. It functions as a cleansing agent that helps water and oil mix together, making it effective at removing makeup, sebum and impurities from the skin.
Beyond cleansing, this ingredient also acts as a hydrotrope and foam booster, helping skincare formulations remain stable and consistent. It is commonly found in cleansers, micellar waters and makeup removers.
How It Works
Surfactants work by having one end that loves water and another that loves oil. This dual nature allows them to surround dirt and sebum, lifting it away from the skin so it can be rinsed off. Disodium Oleamido PEG-2 Sulfosuccinate does this gently, making it less likely to cause irritation than stronger surfactants.
In formulations, it also helps other ingredients dissolve evenly and stay mixed, preventing separation and maintaining product texture.
Clinical Evidence & References
Disodium Oleamido PEG-2 Sulfosuccinate is widely used in the cosmetics industry and is generally recognised as safe by regulatory bodies including the EU and FDA. Its mild nature means it is often chosen as an alternative to harsher surfactants in products designed for sensitive skin.
Limited peer-reviewed research directly compares this ingredient to other surfactants in clinical settings. However, its prevalence in gentle formulations and its history of use suggest a good safety profile for most skin types.
How to Use
This ingredient is most commonly encountered in rinse-off products such as cleansers and micellar waters, where it should be used as directed on the product label. If using a cleanser containing this surfactant, apply to damp skin, massage gently and rinse thoroughly with water. Follow with your other skincare steps.
