Process for manufacture of quaternary ammonium tosylate salts of cinnamidoalkylamines and / or benzamidoalkylamines

摘要

An efficient, simple, high yielding, eco-friendly process for the manufacture of tosylates quaternary ammonium salts of cinnamidoalkylamines and/or benzamidoalkylamines (Formula I) has been described. These compounds are substantive UV-absorbers. They are useful in making fabric care products and personal care products.
