moderateThere is useful support, but formula details and claim strength still matter.
What it is
A phosphate ester surfactant made from synthetic fatty alcohols and ethylene oxide. It is designed to be mild on skin while effectively removing oil-based impurities.
How it works
It reduces the surface tension between water and oil, allowing them to blend. This helps lift sebum, sunscreen, and makeup from the skin so they can be rinsed away easily.
Pros
Gentle on skin
Unlike harsher sulfates, this surfactant cleans effectively without stripping the skin's natural moisture barrier.
Versatile formulator
Works well in both rinse-off and leave-on products, helping create stable, creamy textures that feel pleasant on the skin.
Cons and cautions
Synthetic origin
Made from petrochemical-derived alcohols, which may be a concern for those seeking fully natural formulations.
Potential for mild dryness
In high concentrations or for very dry skin types, it may still cause slight tightness after washing.
Best for
- People with normal to oily skin looking for a gentle cleanser
- Anyone who wears makeup or sunscreen daily and wants effective removal
Use caution if
- Those with severely compromised skin barriers may prefer non-foaming cleansers
