Sodium Methyl 2-Sulfolaurate

TL;DR. This ingredient is an anionic surfactant used for cleansing, foam generation, and soil removal in shampoos, facial cleansers, body washes, and bar formats. It can also help improve lather quality in blends with amphoteric or nonionic surfactants.

What does Sodium Methyl 2-Sulfolaurate do in a cosmetic formula?

This ingredient is an anionic surfactant used for cleansing, foam generation, and soil removal in shampoos, facial cleansers, body washes, and bar formats. It can also help improve lather quality in blends with amphoteric or nonionic surfactants.

Is Sodium Methyl 2-Sulfolaurate clean?

From a clean-beauty perspective, it is generally viewed as an acceptable cleanser with no major restricted-list profile. Like most anionic surfactants, it can feel drying or irritating at higher active levels, so formula concentration and surfactant blending matter.

Is Sodium Methyl 2-Sulfolaurate sustainable?

This material is commonly derived from lauric-rich plant oils such as coconut or palm kernel, so sourcing transparency matters. It is considered readily biodegradable and has a better environmental profile than many persistent synthetic film-formers or silicone-based materials.

Is Sodium Methyl 2-Sulfolaurate COSMOS-approved?

It can be compatible with COSMOS-natural frameworks when made from approved renewable feedstocks using accepted processing routes, though supplier certification should be checked. Its Green Chemistry fit is relatively strong because it can use plant-derived fatty feedstocks and is readily biodegradable, with the main caveat being responsible palm-related sourcing where relevant.

How does Sodium Methyl 2-Sulfolaurate work chemically?

The molecule is a C12 fatty-acid-derived methyl ester bearing an alpha-sulfonate sodium salt, which gives it strong water solubility and high detergency. It is typically used as part of a surfactant system rather than alone, and performance is influenced by water hardness, electrolyte level, pH, and pairing with milder co-surfactants.
