Abstract
The present invention deals with novel amphoteric surfactants that contain a hydroxy containing poly carboxylic group. This class of compounds are hydroxy succinic derivatives made by the reaction of epoxy succinic acid and an amine. The products are high purity, environmentally acceptable surfactants that are simultaneously exceptionally mild to skin and provides good detergency and conditioning of textile fiber, fabric, hair and skin.
