Disodium 2-Sulfolaurate ●
TL;DR. This ingredient is an anionic cleansing surfactant that helps lift oil and soil, create foam, and support rinse-off cleansing systems. It is often used in sulfate-free shampoos, face washes, and body washes as a primary or co-surfactant.
What does Disodium 2-Sulfolaurate do in a cosmetic formula?
This ingredient is an anionic cleansing surfactant that helps lift oil and soil, create foam, and support rinse-off cleansing systems. It is often used in sulfate-free shampoos, face washes, and body washes as a primary or co-surfactant.
Is Disodium 2-Sulfolaurate clean?
It is generally well accepted in clean-beauty frameworks and is not a common restricted-list trigger. Like most cleansing surfactants, it can feel drying or irritating at higher active levels, so mildness depends on the full surfactant blend.
Is Disodium 2-Sulfolaurate sustainable?
This material is typically made from fatty-acid feedstocks that may come from coconut or palm-related supply chains. It is considered readily biodegradable, with lower persistence concerns than many non-biodegradable conditioning polymers or silicones.
Is Disodium 2-Sulfolaurate COSMOS-approved?
It can be used in COSMOS-natural and COSMOS-organic formulas when the feedstock and processing meet the standard’s requirements. Its Green Chemistry profile is favorable when renewable fatty acids are used, supported by biodegradability and efficient surfactant performance at low use levels.
How does Disodium 2-Sulfolaurate work chemically?
The molecule is a C12 anionic surfactant with a fatty chain and two strongly water-loving salt groups, which gives it high solubility and strong cleansing behavior. Typical use is about 1 to 10% active surfactant, often blended with amphoteric or nonionic surfactants to improve mildness, foam feel, and viscosity around mildly acidic to neutral pH.
