What Is Sodium Lauroyl Methyl Isethionate?

Sodium Lauroyl Methyl Isethionate, commonly abbreviated as SLMI, is a mild anionic surfactant used primarily in personal care and cosmetic cleansing formulations.

It is particularly useful where formulators want good cleansing performance and dense foam without relying on traditional sulfate surfactants.

SLMI can be used as the primary surfactant or combined with other mild surfactants to adjust foam, cleansing, viscosity and skin feel.

Its good water compatibility also makes it suitable for both solid and liquid cleansing systems.

Why Formulators Choose SLMI

Mild cleansing

SLMI is commonly selected for formulations where mildness is important, including facial cleansers, shampoos and sensitive-skin cleansing products.

Dense, creamy foam

It produces fine and creamy foam that works well in premium personal care formulations.

Sulfate-free formulation support

SLMI can be incorporated into sulfate-free cleansing systems and combined with other mild surfactants such as SCI, betaines, glutamates and related surfactants.

Good rinseability

Products formulated with SLMI can provide a clean rinse while maintaining a pleasant after-feel on skin and hair.

Suitable for clear formulations

Compared with less water-soluble solid surfactants, SLMI can be easier to incorporate into certain liquid and transparent cleansing systems.

Typical Applications of SLMI

Shampoo and sulfate-free shampoo

SLMI is widely used in mild shampoo formulations where formulators need a balance between cleansing, foam and scalp comfort.

It can be used alone or blended with amphoteric and nonionic surfactants.

Shampoo bars and syndet bars

SLMI can also be used in solid cleansing systems and shampoo bar formulations, particularly when a finer, creamier foam profile is desired.

Facial cleansers

Its mild cleansing profile makes Sodium Lauroyl Methyl Isethionate suitable for facial wash and premium cleansing formulations.

Body wash and shower gel

SLMI can contribute creamy foam and good rinsing properties in sulfate-free body cleansing systems.

Cleansing bars

It can be incorporated into syndet and soap-free cleansing bars either as a primary surfactant or as part of a blended surfactant system.

Baby and sensitive-skin formulations

Where the complete formulation has been properly evaluated, SLMI may be considered for mild cleansing systems designed for more sensitive applications.

SLMI vs SCI: Which One Should You Choose?

SLMI and Sodium Cocoyl Isethionate (SCI) are both widely used in mild personal care formulations, but they behave differently during formulation.

For formulators developing clear or liquid products, SLMI may offer greater formulation flexibility.

For solid shampoo bars and syndet bars, SCI remains one of the most established choices.

Many manufacturers also use SLMI and SCI together to balance foam, mildness, processing and product texture.

How to Use Sodium Lauroyl Methyl Isethionate

SLMI is typically dissolved or dispersed into the aqueous phase during processing.

For many formulations, heating the water phase to approximately 50–60°C can help incorporation.

The exact processing method and use level depend on:

• product format
• total surfactant system
• desired viscosity
• target foam profile
• pH
• other ingredients in the formulation

For commercial formulation work, we recommend confirming the latest technical data before scaling up production.

Recommended Formulation pH

SLMI performs well in mildly acidic to near-neutral personal care formulations.

A formulation pH around 4.5–8.5 can generally be considered during development, depending on the total formulation.

Final product stability, compatibility and preservation should always be validated by the formulator.
