Ingredient review
Disodium 2-Sulfolaurate
INCI: DISODIUM 2-SULFOLAURATE
A gentle, biodegradable surfactant that cleans effectively without stripping the skin barrier.
In plain English
Disodium 2-Sulfolaurate is a mild cleansing ingredient made from lauric acid, a fatty acid found in coconut or palm oil. It helps remove dirt, oil, and makeup from your skin and hair without causing the tight, dry feeling that harsher cleansers can leave behind. Because it's gentle, it's often used in sulfate-free and sensitive-skin formulas.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Disodium 2-Sulfolaurate is a surfactant (a cleansing agent) derived from lauric acid, which is commonly sourced from coconut or palm kernel oil. It is chemically modified to be water-soluble and mild on skin.
How it works
It works by reducing the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. Its molecular structure is larger and less penetrating than traditional sulfates, which makes it less likely to irritate or dry out the skin.
Pros
Gentle on skin
Its mild nature makes it suitable for sensitive skin and daily use without stripping natural oils.
Eco-friendlier option
It is biodegradable and often used as a replacement for harsher, less sustainable surfactants like SLS.
Cons and cautions
Lower foam volume
It produces less lather than traditional sulfates, which may be less satisfying for those who equate foam with cleansing power.
Sourcing concerns
Derived from palm or coconut oil, its environmental impact depends on sustainable sourcing practices.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone seeking sulfate-free or low-irritation cleansing products
Use caution if
- Those who prefer very high-foaming cleansers may find it less satisfying
