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 (cleansing agent) derived from petroleum, designed to reduce surface tension between oil and water for effective cleansing.

How it works

It lowers the surface tension between water and oil, allowing oily dirt and makeup to be broken into tiny droplets that can be rinsed away with water. This makes it useful in foaming cleansers and shampoos.

Pros

Effective cleanser

Removes excess oil, makeup, and impurities efficiently, leaving skin feeling clean.

Good lather

Creates a satisfying foam that many people associate with thorough cleansing.

Cons and cautions

Potential dryness

May strip natural oils, leading to tightness or flakiness, especially with frequent use.

Irritation risk

Can cause stinging or redness for those with compromised skin barriers or conditions like rosacea.

Best for

  • People with normal to oily skin who use rinse-off cleansers
  • Those looking for effective makeup removal

Use caution if

  • Individuals with dry, sensitive, or eczema-prone skin
  • Anyone seeking a gentle, non-stripping cleanser

Usage tips

Use only in rinse-off products and avoid leaving on the skin for extended periods.
Follow with a moisturizer to replenish hydration after cleansing.

Safety summary

Generally considered safe for use in rinse-off cosmetics at typical concentrations, but may cause irritation or dryness for sensitive individuals. Avoid contact with eyes.

Research notes

Limited peer-reviewed studies specifically on this ingredient; safety is inferred from broader surfactant research. Industry panels (e.g., CIR) have reviewed similar ethoxylated surfactants and found them safe when formulated properly.
