ABSTRACT:
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.The scope of this methodology has been demonstrated by converting water soluble organic sunscreen quaternary halides to their corresponding tosylates of Formula VI.
