Procedure

This example illustrates the use in an anionic surfactant composition of an octenylsuccinic acid liquid-stabilizing agent. An aqueous disodium octenylsuccinate (about 35%) was prepared from octenyl succinic anhydride (OSA from Dixie Chemical, Houston, Tex.) and aqueous sodium hydroxide. According to the manufacturer of the OSA, this material is reportedly predominantly 1-OSA, but some 2-OSA is also present.
