More Information
Summary:The reaction of 2-alkylimidazolines with ethylene oxide or propylene oxide gives quaternary 2-alkyl-2-imidazolinium salts corresponding to the following general formula (I) wherein R1 represents a straight-chain or branched-chain substituted or unsubstituted alkyl or alkenyl radical containing from 7 to 21 carbon atoms, R2 represents one of the following radicals R3 represents hydrogen or methyl, R4 represents hydrogen or methyl, X(-) represents the anion of a non-oxidizing and non-corrosive inorganic acid or of an organic mono- or polycarboxylic acid, n statistically represents a whole or fraction number of from 1 to 20, and m represents an integer of from 1 to 3, which may be used for softening laundered fabrics.
