A sulfosuccinate surfactant based on undecylenic acid monoethanolamide, regulated in Annex III.
What it is
Disodium undecylenamido MEA-sulfosuccinate is, according to CosIng, the disodium salt of a sulfosuccinic acid half-ester of undecylenic acid monoethanolamide, an anionic surfactant. CosIng lists it as a cleansing, foam-boosting, hydrotrope and cleansing-surfactant ingredient. In the EU it is covered by an entry in Annex III (substances subject to restrictions) that applies to monoalkylamines, monoalkanolamines and their salts.
Where it is used
Appears on the ingredient lists of a small number of cleansing products.
Limits of interpretation
The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.
See the EU regulation section for the applicable limits and conditions.
