  • Patent number: 4139479
    Abstract: A textile-treating composition comprises a fabric-substantive cationic surfactant and a water-insoluble salt of a carboxylic acid having from 16 to 24 carbon atoms. Particularly useful water-insoluble salts are the calcium, aluminium or magnesium salts of stearic acid. Fabrics treated with the composition, either directly or in dilute aqueous solution, have enhanced softness and antistatic properties.
    Type: Grant

  • Patent number: 4126562
    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.
