Sodium Lauroyl Methyl Isethionate for skin :Benefits and Safety

Updated: Nov 30, 2023

Sodium Lauroyl Methyl Isethionate

Ingredient labels can be confusing, with long and complicated scientific names. But it's important to understand what's in the products you buy. That's why we're talking about Sodium Lauroyl Methyl Isethionate (SLMI).

In the past, sodium cocoyl isethionate (SCI) was the main raw material used to make soap, shower gel, and bath liquids. However, SCI has low solubility in water and is difficult to dissolve in water at room temperature, which means it is not flexible enough for most applications.

As an improved product, sodium lauroyl methyl isethionate (SLMI) solves the problem very well. SLMI is easily soluble in water at room temperature, and its other properties are better than SCI. Therefore, sodium lauroyl methyl isethionate is a new, mild anionic surfactant that is widely used in today's beauty, baby, and personal care products. Its characteristics include:rich foam,smooth skin feel after washing,strong cleaning ability and biodegradable.

What is Sodium Lauroyl Methyl Isethionate?

Sodium lauroyl methyl isethionate is formed by adding a methyl group to sodium lauroyl isethionate. There is a dramatic change in properties after just a small change.

Besides its excellent water solubility and long-lasting foam, this ingredient is an incredibly mild surfactant, making it suitable even for sensitive skin; Not to be confused with similar-sounding sodium lauryl sulfate, it is a natural product, pH stable (from 4.5 to 8.5). and is considered to be one of the safest on the market.

Sodium Lauroyl Methyl Isethionate for skin

SLMI does not contain sulfates, the harsh cleansing agents that can irritate the skin and cause dryness. Sulfates are often found in shampoos and body washes, but SLMI is a gentle alternative that is suitable for even the most sensitive skin.

SLMI has some conditioning properties that can help to leave the skin feeling soft and smooth. Unlike harsh detergents that can leave the skin feeling dry and tight, SLMI leaves the skin feeling hydrated and nourished.

How safe is it?

With an EWG score of 1, Sodium Lauroyl Methyl Isethionate is deemed to be very safe, non-toxic, a non irritant, and is biodegradable.

 Safe for use in a variety of personal care products including facial cleansers, body washes, shampoos, and conditioners.


Sodium Lauroyl Methyl Isethionate Foamability

The measurement of product foaming and stability shows that sodium lauryl methyl isethionate has good foaming performance. At the initial foaming stage, it has a foam height of 226mm. After 5 minutes of continuous foaming, the height of the foam decreased slightly, indicating that the SLMI has good foaming performance and foam stability.
