Abstract
Abstract A textile treatment composition comprises certain polyamine salts and nonionic fabric conditioning substances which are fatty acid esters of alcohols or anhydrides having up to 8 carbon atoms. Particularly useful polyamine salts have a higher alkyl substituent and have ethoxylate or polyethoxylate substituents on the nitrogen atoms. Glycerol stearates and sorbitan stearates are preferred nonionic agents. The highly charged cationic species provide an excellent carrier system to encourage deposition of the nonionic fabric conditioner on fabrics which are rinsed in dilute aqueous solutions of the composition.
