Disodium 4-(undecylenic monoethanolamide) sulfosuccinate

Disodium 4-(undecylenic monoethanolamide) sulfosuccinate (CAS 26650-05-5) is an anionic surfactant derived from undecylenic acid, a naturally sourced fatty acid with recognized antifungal properties. It functions as a mild cleansing, foaming, and emulsifying agent suited to both personal care and cleaning formulations. In shampoos, body washes, and facial cleansers, it delivers effective cleansing.

The foam profile is highly compatible with sensitive-skin positioning. Its undecylenic acid origin makes it a preferred choice in antifungal foot care products, dandruff treatments, and scalp formulations. In these applications, the active component adds functional value beyond simple surfactancy. In home care and industrial cleaning products, it contributes to emulsification and soil dispersion in liquid systems.

It also serves as a co-surfactant in specialty formulations where formulators need to balance mildness with cleaning performance. This versatility makes it a staple in modern chemical manufacturing. The product is typically supplied as an aqueous solution, with active matter content commonly in the range of 30–35%. It is available in technical and cosmetic grades to meet various requirements.

These grades ensure suitability for personal care and industrial end markets. Packaging options generally include drums and intermediate bulk containers suited to industrial procurement volumes.
