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.

Lauramine Oxide CAS 1643-20-5

Lauramine Oxide is a mild-to-efficient amine oxide surfactant used in cleansing and detergent formulations where foam boosting, foam stabilization, and formulation compatibility are important. It is commonly used in shampoos, body washes, facial cleansers, dishwashing liquids, and other liquid cleaning systems, and is often blended with other surfactants to improve foam profile and viscosity performance. As a supplier, we can support regular industrial supply with standard export packaging and technical documents such as COA, TDS, and SDS according to the actual product grade and batch. For coconut-derived amidoamine oxide systems, Cocamidopropylamine Oxide is a related surfactant to compare by active matter, viscosity response and blend compatibility.
