Description

(n-Dodecyl-N,n-Dimethylammonio)Undecanoic Acid is a high-purity zwitterionic surfactant and betaine derivative, valued for its excellent surface-active properties and stability across a wide pH range. Its unique molecular structure makes it a critical component for formulating high-performance, mild, and stable products. This compound is essential for manufacturers in the personal care, home care, and specialty chemical industries seeking advanced amphoteric surfactants.

Application

• Primary Surfactant & Co-surfactant in mild shampoos, body washes, and facial cleansers.
• Viscosity Modifier and Foam Booster in liquid soaps, hand sanitizers, and bubble baths.
• Key ingredient in Home Care Formulations such as hard surface cleaners and dishwashing liquids for enhanced grease cutting and compatibility.
• Industrial & Institutional (I&I) Cleaning applications requiring stable, high-foaming, and low-irritancy surfactants.
• Additive in Enhanced Oil Recovery (EOR) formulations and other oilfield chemicals.
• Stabilizing Agent in emulsion and dispersion systems for agrochemicals and coatings.
• Biocompatible surfactant for use in pharmaceutical and cosmetic nanoemulsions.
