Score terms in plain English

Irritation risk

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

Clogging risk

low

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 hydantoin, a chemical building block, combined with lauric acid (a fatty acid from coconut or palm oil). It is designed to reduce surface tension between water and oil.

How it works

It works by lowering the surface tension between water and oil, allowing them to mix. This helps lift dirt, oil, and makeup from the skin or hair so they can be washed away with water.

Pros

Effective cleanser

Helps remove excess oil, dirt, and makeup without being overly harsh for most skin types.

Foam booster

Creates a satisfying lather that many people enjoy in their daily cleansers and shampoos.

Cons and cautions

Potential dryness

Can strip natural oils from the skin, leading to tightness or flakiness, especially if used too frequently.

Irritation risk

May cause stinging or redness for those with sensitive skin or conditions like eczema.

Best for

  • People with normal to oily skin
  • Those who prefer foaming cleansers

Use caution if

  • People with very dry or compromised skin
  • Those with known sensitivity to surfactants

Usage tips

Use a gentle, non-foaming cleanser if your skin feels tight after washing.
Follow up with a moisturizer to replenish hydration after using a cleanser containing this ingredient.
