1. A concentrate comprising, by weight, (a) 25% to 35% of a saturated fatty acid selected from stearic or palmitic acid, or mixtures thereof, in an adduct of an amidopropyldimethyl-2-hydroxyethyl ammonium halide, with substantially no free acid present, and (b) 65% to 75% of an alcohol, selected from a low molecular weight alcohol or a saturated fatty alcohol or alcohols, or mixtures thereof wherein the concentrate has a residual ethylene chlorohydrin level of <100 ppm.

2. A concentrate according to claim 1 wherein (b) is cetearyl or behenyl alcohol, or a mixture thereof, or propylene glycol, butylene glycol or isopropyl alcohol.

3. A concentrate according to claim 1 wherein (a) is about 30% and (b) is about 70%.

4. A concentrate according to claim 2 wherein (b) is a mixture of about half of cetearyl and half of behenyl alcohols.

5.
