What is Lauramine Oxide CAS 1643-20-5?

Lauramine Oxide, also called lauryl dimethylamine oxide or dodecyldimethylamine oxide, is an amine oxide surfactant with CAS 1643-20-5, EC No. 216-700-6, and molecular formula C14H31NO. It is commonly supplied as a clear to pale yellow liquid for use in cleansing and detergent formulations.

What are the main applications of Lauramine Oxide?

It is used in shampoo, body wash, shower gel, facial cleanser, dishwashing liquid, household cleaning products, and industrial or institutional liquid detergent systems. It is typically selected as a co-surfactant to improve foam, compatibility, and formulation feel.

What functions does Lauramine Oxide provide in a formulation?

Lauramine Oxide mainly provides foam boosting, foam stabilization, and viscosity support in suitable surfactant systems. It can also contribute wetting and mildness benefits, especially when combined with anionic or amphoteric surfactants.

What is the common supply form and active content of Lauramine Oxide?

Commercial Lauramine Oxide is usually supplied as a water-soluble aqueous liquid, often around 30% active content, with some grades in the 28-35% range. The exact active matter, pH, and concentration should be confirmed against the selected grade because these values vary by manufacturer.

How is Lauramine Oxide different from cocamidopropylamine oxide?

Both are amine oxide surfactants, but Lauramine Oxide is based on a lauryl/dodecyl dimethyl amine oxide structure, while cocamidopropylamine oxide contains a cocamidopropyl group and a different CAS. They can have different foam, compatibility, and handling profiles, so they should be selected by formulation testing rather than treated as direct substitutes.
