摘要：
A three-step method for preparing textile treatment compositions comprising mixtures of substituted imidazoline fabric softener materials and protonating acids is provided. In Step (1) the imidazoline is heated, and in Step (2) it is protonated in a concentrated acid/water seat. Step (3) comprises diluting this mixture with additional water. Utilizing this method provides compositions having good product stability, dispersibility, and concentratability, as well as excellent fabric softening characteristics.
