Sodium Lauroyl Isethionate

Sodium lauroyl isethionate is a mild anionic surfactant derived from coconut oil. It functions as a cleansing agent that helps water and oil mix together, allowing dirt, sebum, and makeup to be rinsed away effectively.Unlike harsher surfactants, this ingredient is designed to be gentler on the skin barrier whilst still delivering effective cleansing. It's commonly found in facial cleansers, body washes, and some conditioning products, where it contributes both cleansing and mild conditioning properties.

Surfactants have a molecular structure with one end that attracts water and another that attracts oil. This allows them to surround dirt and oils on the skin, lifting them away so they can be rinsed off with water.Sodium lauroyl isethionate is considered a milder surfactant because it causes less disruption to the skin's natural lipid barrier compared to stronger cleansing agents. This means it can effectively clean whilst being less likely to trigger irritation or dryness in most people.

This ingredient is typically used in rinse-off products like cleansers, so you don't need to worry about concentration or frequency — simply use your cleanser as directed, usually morning and evening or as needed. If you have very reactive skin, you can patch test first, though adverse reactions are uncommon.

Sodium lauroyl isethionate is well-tolerated by most people and is approved for use in cosmetics across major regulatory bodies. It is unlikely to cause irritation, though those with severe sensitivity to surfactants should be aware of this ingredient in formulations.
