Abstract: A natural gum is used to provide emulsification of alkenyl succinic anhydride (ASA) sizing agents for paper products. The natural gum can be nonionic, cationic, anionic, amphoteric, oxidized, derivatized or modified. The alkenyl succinic anhydride size emulsion formed with the natural gum improves stability and the film formed is evenly distributed, thereby promoting more uniform sizing of the paper product. The ratio of the ASA to natural gum in the emulsion ranges from 0.01:1 to 100:1, and preferably 0.1:1 to 20:1. The amount of ASA size is 1 lb./ton to 10 lbs./ton of finished paper product. A surfactant may be used to further improve the stability of the emulsion.
