General description

Alkyltrimethylammonium bromide is a surfactant and can be used to study the forces and stability of foam films produced from soluble cationic surfactants.

Application

Alkyltrimethylammonium bromide has been used in a study to assess the adsorption of sugar surfactants at the air/water interface. It has also been used in a study to investigate dynamical features in cationic micelles.

Other Notes

Predominantly C14H29N(CH3)3Br but also contains C12 and C16 homologs.
