Sodium Laureth Sulfate

What Sodium Laureth Sulfate is & what it does

A common cleansing surfactant that creates a rich lather and removes oil and dirt. It is milder than sodium lauryl sulfate but can still be drying for sensitive skin.

What does Sodium Laureth Sulfate do in cosmetics?

Sodium Laureth Sulfate, often abbreviated SLES, is commonly used as a cleansing agent and foaming surfactant in products like cleansers, shampoos, and body washes. It helps lift away oil and dirt and creates a rich lather. It is one of the most widely used surfactants in personal care.

Is Sodium Laureth Sulfate safe for skin?

Sodium Laureth Sulfate is widely used and considered acceptable for use in rinse-off cosmetics. Because it is an effective cleanser, it can feel drying or irritating for some people, especially at higher levels or on sensitive skin. Choosing gentler or lower-sulfate formulas is an option if your skin reacts.

Is Sodium Laureth Sulfate natural or synthetic?

Sodium Laureth Sulfate is a synthetic surfactant, although it can be made from both plant-derived and petroleum-derived raw materials. The starting oils, such as coconut or palm, are processed chemically to create the final ingredient. The result is a consistent, well-defined cleansing agent.
