What it is
A synthetic surfactant derived from myristyl alcohol and decanoic acid, modified with propylene glycol and hydroxyethyl groups to improve mildness.
How it works
It lowers the surface tension between water and oil, allowing dirt, sebum, and makeup to be emulsified and rinsed away. Its structure is engineered to be less disruptive to skin proteins and lipids than traditional sulfates.
Pros
Very gentle on skin
Designed to clean without stripping natural oils, making it ideal for daily use on sensitive or dry skin.
Sulfate-free alternative
Provides effective cleansing without the harshness of sodium lauryl sulfate, reducing the risk of irritation.
Cons and cautions
Lower foam production
Creates less lather than traditional sulfate cleansers, which some users may find less satisfying.
Synthetic origin
Manufactured through chemical synthesis, which may not appeal to those seeking all-natural formulations.
Best for
- People with sensitive or easily irritated skin
- Those looking for a sulfate-free, gentle cleanser
Use caution if
- Individuals who prefer completely natural or plant-derived ingredients
