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. ##STR00001##
The scope of this methodology has been demonstrated by converting water
soluble organic sunscreen quaternary halides to their corresponding
tosylates of Formula VI. ##STR00002##
