Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

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

Usage tips

Use in rinse-off products like cleansers and body washes for best results.
Pair with other mild surfactants to adjust foam and cleansing strength.

Safety summary
