CAS: 7381-01-3
Sodium Lauroyl Isethionate is a mild, anionic surfactant derived from coconut fatty acids and isethionic acid. It provides excellent foaming, cleansing, and skin conditioning properties while being gentle on skin and eyes, making it ideal for sulfate-free formulations. It produces a dense, creamy lather even in hard water and is commonly used in low-irritation cleansing products. It is readily biodegradable and contributes to a soft, moisturizing after-feel.

Sodium lauroyl isethionate is used as a mild anionic surfactant in a wide range of applications. It is commonly found in personal care products such as shampoos, facial cleansers, body washes, and syndet bars. It is also used in cleaning products, coatings, and other water-based systems where effective cleansing, foaming, and mildness are important.
Manufacturers choose sodium lauroyl isethionate because it provides strong performance while remaining gentle on skin and compatible with modern formulations.
No, sodium lauroyl isethionate is not a sulfate. While it is an anionic surfactant, it belongs to the isethionate class rather than the sulfate class.
Because of this distinction, sodium lauroyl isethionate is widely used in products marketed as sulfate-free. It offers many of the cleansing and foaming benefits associated with sulfates, but with improved mildness and skin compatibility.
Sodium lauroyl isethionate is used in personal care products because it delivers an effective balance of performance and mildness. It produces a rich, creamy lather, cleans without stripping moisture, and is gentle enough for frequent-use and sensitive-skin formulations.
Its performance in hard water, compatibility with sulfate-free systems, and ability to improve after-feel make it a reliable choice for modern shampoos, cleansers, and body care products.
