Is C12-14 Alkyl Dimethyl Amine Oxide the same material as Lauramine Oxide?

Not by name alone. “Lauramine Oxide” is used for commercial materials with different CAS numbers and chain distributions; CAS 308062-28-4 identifies the C12-C14 mixture. Compare the CAS, EC/List number, chain distribution, active matter and solution form.

Which specifications matter when comparing C12-C14 Amine Oxide solutions?

Compare active matter, free amine, residual hydrogen peroxide, pH, colour and alkyl-chain distribution. Align the analytical methods and reporting basis, including the average molecular mass used to calculate active matter or free amine and the dilution used for pH measurement. State whether percentages refer to the supplied solution or its active matter.

What should be checked before using C12-C14 Amine Oxide with anionic surfactants?

Amine oxide behaviour depends on pH: it is predominantly nonionic at neutral or alkaline pH and becomes more cationic under acidic conditions. Confirm final pH, surfactant ratio, electrolyte level, viscosity and foam profile. Test compatibility and salt response in the complete formulation rather than assuming that all anionic blends behave alike.
