Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic, water-soluble surfactant derived from lauryl alcohol and phenyl ether, modified with sulfonate groups to improve mildness and foaming.
How it works
It reduces the surface tension of water, allowing it to penetrate oils and lift away dirt, sebum, and makeup. Its large molecular structure makes it less penetrating into the skin barrier, which reduces irritation potential.
Pros
Gentle on skin
Its large molecular structure means it stays on the surface of the skin rather than penetrating, reducing the risk of irritation and dryness.
Sulfate-free alternative
Provides a rich foam without using sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES), which can be harsh for some skin types.
Cons and cautions
Not for heavy-duty cleansing
It may struggle to remove long-wear or waterproof makeup on its own, so you might need an oil-based pre-cleanse.
Synthetic ingredient
If you prefer exclusively natural or plant-derived ingredients, this synthetic surfactant may not align with your preferences.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone who prefers sulfate-free cleansing products
Use caution if
- Those seeking a deep-cleansing formula for heavy makeup or sunscreen removal may need a double-cleanse routine
