Abstract
Abstract Novel salts of 1,3-bis-(β-ethylhexyl)-5-amino-5-methyl-hexahydropyrimidine (hexetidine) with substituted benzoic acids and processes of preparing these salts are described. These novel salts have useful bacteriostatic activity and show stability in storage. The invention accordingly comprises compositions containing the novel salts and having bacteriostatic activity. The salts are additionally useful for the purification of hexetidine contained in raw mixtures obtained from the synthesis of this compound.
