Disodium Laureth Sulfosuccinate
EWG Skin Deep Hazard Score:
2 (should be higher)
What is it:
Disodium laureth sulfosuccinate is a surfactant (detergent) used in shampoos for cleansing and foam boosting.
What are its risks:
- DLS is created using the carcinogen ethylene oxide, traces of which can remain in the product, along with its carcinogenic by-product 1,4-dioxane.
- Skin irriation (source)
- Eye irritation (source)
There is not much information out there about this chemical, however, accoring to current sources it is fairly biodegradeable and not a reproductive toxin. While it may be more gentle on hair and skin than SLS, the main concern with disodium laureth suflosuccinate is the fact that it's an ethoxylated chemcial that may contain traces of carcinogenic 1,4-dioxane and/or ethylene oxide.
