Abstract:
The present invention relates to a new process for synthesizing an amido alkyl betaine starting from a linear alcohol having from 8 to 22 carbon atoms, to an amido alkyl betaine prepared by the process with increased viscosity in water, and also to use thereof as a viscoelastic surfactant in oil and gas applications and home personal care applications. The present invention also relates to a process for synthesizing an amido amine starting from a linear alcohol having from 8 to 22 carbon atoms, and to an amido amine prepared by the process.
