Sodium Lauryl Sulfate

What Sodium Lauryl Sulfate is & what it does

A strong cleansing and foaming surfactant that effectively removes oil and dirt. It is very effective but can be drying and irritating, especially on sensitive skin.

What does Sodium Lauryl Sulfate do in skincare?

Sodium Lauryl Sulfate (SLS) is a strong surfactant and foaming agent used mainly in cleansers, shampoos, and wash-off products. It lifts away oil and dirt and produces a rich lather. Because it is an effective cleanser, it is more common in rinse-off products than in leave-on skincare.

Is Sodium Lauryl Sulfate safe?

Sodium Lauryl Sulfate has a long history of use in cleansers and is generally considered safe in rinse-off products at standard levels. It can be drying or irritating for some people, especially those with sensitive or dry skin, since it is a strong cleansing agent. If you find cleansers irritating, a milder surfactant may suit you better.

Is Sodium Lauryl Sulfate vegan?

Sodium Lauryl Sulfate can be made from either plant-derived sources, such as coconut or palm oil, or from petroleum, and the synthesis itself does not require animal material. This means it is generally compatible with vegan formulas, though the original feedstock varies by supplier. Check with the brand if you want confirmation of the source.
