Frequently Asked Questions

What is linoleamidopropyl dimethylamine?

Linoleamidopropyl dimethylamine (CAS 38517-23-6) is a fatty amidoamine derived from linoleic acid. It is used as a conditioning and antistatic surfactant and emulsifier in hair- and skin-care formulations; its tertiary amine protonates to a cationic conditioning species in acidic systems.

How is linoleamidopropyl dimethylamine used in hair care?

When protonated at formulation pH it becomes cationic and adsorbs onto hair to provide conditioning and antistatic effect, functioning as an alternative to quaternary conditioners. It also acts as an emulsifier to stabilize personal-care emulsions.

Is linoleamidopropyl dimethylamine cationic or amphoteric?

It is a tertiary amine (amidoamine), not a permanent quaternary. It behaves as a weak-cationic conditioner: neutral at high pH and protonated to a cationic species in acidic systems, which is why conditioner formulas typically adjust pH to activate it.

What is the CAS number for linoleamidopropyl dimethylamine?

It carries CAS 38517-23-6. Reference this identifier on the Certificate of Analysis to confirm identity against your formulation specification.
