AMPHOTERIC DETERGENT COMPATIBLE SOFTENERS BASED ON ALKYL AMMONIUM BACKBONE

摘要

The present invention provided amphoteric detergent compatible amphoteric softeners based on alkyl ammonium backbone of formula 1, 2 or 3. These softeners may be used directly to impart softness to the substrates such as fabrics. The invention also provides a method for preparation of these softeners by reaction of maleic anhydride with a mixture of long chain alcohols or glycols and then with a mixture of amine and olefinic acid and a polymerization inhibitor. The softeners of the present invention are used as such or in combination with cationic as well as anionic additives without any special additive. These softeners do not impart additional yellowing characteristics to the fabric.
