Abstract
Novel imidazolinium compounds, and a method of using the compounds for softening and conditioning fibers, hair and skin and as surfactants, and debonders for cellulose pulp having the general formula: ##STR1## wherein R.sub.1 is an n-alkyl, branched alkyl, alkenyl, branched alkenyl alkadienyl or branched alkadienyl group containing 8 to 21 carbon atoms; R.sub.2 is a radical selected from the group consisting of (a) --OH, (b) amide radicals each of which has the structure ##STR2## (c) a substituted imidazolinium group which has the structure: ##STR3## R.sub.3 is a radical which has the structure ##STR4## or --OR.sub.5 ; R.sub.4 is an alkyl or alkenyl group containing 1 to 17 carbon atoms; R.sub.5 is R.sub.1 or mono or dialkyl phenyl; A is an integer of from 0 to 20 and B is an integer of from 0 to 20 and A+B>0; x is either chlorine or bromine are provided.
