Description

Lauramine oxide (CAS 1643-20-5 ), also known as LDAO, is an amphoteric surfactant that functions as a foam booster, viscosity modifier, and conditioning agent across personal care and industrial cleaning formulations. Its behavior shifts between nonionic and cationic depending on pH, making it compatible with a broad range of surfactant systems. In shampoos, body washes, and liquid hand soaps, it thickens formulations effectively. It stabilizes foam generated by primary surfactants such as sulfates or sulfonates. Industrial and institutional cleaning products rely on it to boost detergency and improve soil removal on hard surfaces without aggressive chemistry. In fabric care and conditioning formulations, it contributes to softness and antistatic performance. Coatings and adhesive formulations use it as a dispersing and stabilizing agent to maintain emulsion integrity. This material ensures stability during processing and storage. Lauramine oxide is supplied as an aqueous solution, typically at 30% active content, though concentrations vary by manufacturer. It is available in technical and industrial grades suited to cleaning and coatings applications, as well as cosmetic-grade material meeting personal care quality standards. Bulk liquid supply is the standard format. Commercial distribution is typically managed in IBC containers or drums. This versatile surfactant remains a staple for formulators seeking high performance and compatibility in diverse chemical environments. Contact us for supply of Lauramine oxide Request Quote
