C12–14 Alkyldimethylamine in Alkyl Betaine Production

China Amines Co., Limited

“Please send a betaine sample for our shampoo project” sounds like a straightforward request. Before anyone packs a sample, though, it helps to ask which material the team needs. A surfactant producer developing an alkyl betaine and a shampoo formulator evaluating cocamidopropyl betaine (CAPB) are buying at different points in the supply chain.

Where C12–14 alkyldimethylamine fits

C12–14 alkyldimethylamine is a fatty tertiary amine used upstream in chemical manufacturing. Eastman’s technical data sheet lists its DIMLA™ 1214 grade as an intermediate for producing betaines and sulfobetaines. In an alkyl betaine project, the surfactant manufacturer evaluates the tertiary amine as a feedstock. The formulation team evaluates the resulting surfactant against the requirements of the finished product.

Write the full ingredient name in the brief

Alkyl betaine describes a family of surfactants. Cocamidopropyl betaine identifies a specific ingredient type. If a shampoo formula calls for CAPB, write out Cocamidopropyl Betaine on the sample request and match it against the supplier’s ingredient documentation. If the project is to manufacture an alkyl betaine, specify the intended derivative and the tertiary amine feedstock separately. The word betaine saves space in an email, but it can cost a round of samples.

Ask for data that match the stage of the project

For a feedstock trial, tell the supplier which derivative you intend to make and which raw material properties your process needs to control. If your specification calls for a particular C12/C14 distribution, include the target range in the request.

For a shampoo or body wash trial, identify the finished surfactant by its full ingredient name and ask for its active matter content. Then evaluate it in the complete formulation, using the clarity, viscosity and foam criteria set for that product.

Discuss your alkyl betaine feedstock requirements

If you manufacture alkyl betaines and are sourcing C12–14 alkyldimethylamine, send China Amines your intended derivative, required feedstock specification, trial quantity and delivery destination. Include your expected order volume and preferred packaging so the offered grade and supply options can be reviewed together.
