Description

Disodium Undecylenamido MEA-Sulfosuccinate is a high-performance, mild anionic surfactant derived from undecylenic acid. This specialty chemical is valued for its excellent foaming, cleansing, and emulsifying properties, combined with exceptional mildness to skin and hair. It is a critical ingredient for formulators in the personal care and cosmetic industries seeking to create gentle yet effective cleansing products. Its unique structure provides compatibility with a wide range of other surfactants and actives.

Application

• Primary Surfactant in Mild Cleansers: Used as the main foaming agent in baby shampoos, sensitive skin facial washes, and sulfate-free cleansing systems.
• Co-Surfactant for Foam Boosting: Enhances and stabilizes foam in combination with other anionic surfactants like SLES (Sodium Laureth Sulfate) or betaines.
• Personal Care Formulations: Key ingredient in shower gels, bubble baths, liquid hand soaps, and facial cleansers where mildness is a priority.
• Hair Care Products: Incorporated into shampoos and scalp treatments designed for frequent use or for damaged, color-treated hair.
• Cosmetic Emulsification: Functions as an emulsifier in certain rinse-off and leave-on cosmetic products, helping to blend oil and water phases.
• Industrial & Institutional (I&I) Cleaners: Applied in formulations for light-duty industrial cleaners and hand soaps where skin compatibility is important.
