Disodium Laureth Sulfosuccinate

Today's Chemical:

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

Steph's Opinion:

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.

Are there likely to be residual sulphites in Disodium Laureth Sulfosuccinate because of the method of manufacturing?

What's your opinion of the unethoxylated version, disodium lauryl sulfosuccinate, or of diammonium lauryl sulfosuccinate?

Thanks for the information. Agree on the EWG score needing to be higher than 2.
