What is Sodium Lauroyl Methyl Isethionate CAS 928663-45-0?

Sodium Lauroyl Methyl Isethionate, commonly abbreviated SLMI, is a mild anionic isethionate surfactant derived from coconut fatty acid. It is used in personal care formulations as a sulfate-free cleansing and foaming agent.

Is SLMI suitable for sulfate-free shampoo and body wash formulations?

Yes. SLMI is widely selected for sulfate-free systems because it provides effective cleansing with a dense, creamy lather and lower irritation potential than many traditional sulfate surfactants. Its high water solubility also makes it useful in transparent formulations.

Which personal care products typically use Sodium Lauroyl Methyl Isethionate?

SLMI is used in facial cleansers, shampoos, body washes, syndet bars, baby cleansing products, and other mild personal care cleansing systems. It is often paired with amphoteric or nonionic surfactants to improve foam and skin feel.

What supply forms and key specifications should be checked for SLMI?

It is commonly supplied as white to off-white powder, flakes, granules, or commercial liquid depending on grade. Buyers should check appearance, active content, ionic type, and pH; liquid commercial forms are often in the 30-35% active matter range, while solid forms may have higher active content.

It is used in facial cleansers, shampoos, and syndet bars.

It is used in body washes and baby cleansing products.

It provides gentle cleansing, stable foam, and good skin compatibility.

It is widely selected for sulfate-free systems because it provides effective cleansing with a dense, creamy lather and lower irritation potential.

It is based on a lauroyl C12 chain and tends to have excellent water solubility, allowing clear sulfate-free shampoo and cleansing systems.

Confirm appearance, active content, ionic type, pH, physical form, and compatibility with the target formulation.

Store in tightly closed containers in a cool, dry, well-ventilated area, away from moisture and direct sunlight.

Use suitable PPE when handling the material to prevent dust exposure and skin or eye contact.

Confirm packaging suitable for the physical form and order quantity, and follow the current SDS.
