Patent number: 8747616Abstract: The invention is directed towards methods and compositions for improving the sizing of paper using PAE. Proper sizing of paper requires that a sizing agent adequately disperse so as to evenly distribute on the paper. Proper sizing also requires that the agent not cause runnability or chemical problems with other materials or equipment used in the papermaking process. PAE displays unexpected attributes that allow it to disperse sizing agents. Best of all it is not subject to the same overdose effect of typical emulsifiers such as cationic starch. As a result PAE is an excellent option for use in sizing paper.Type: GrantFiled: September 12, 2012Date of Patent: June 10, 2014Assignee: Ecolab USA IncInventors: Gary S. Furman, Jr., Robert M.

Patent number: 6472440Abstract: Defoamers are the products of the reaction of epichlorohydrin and compounds having the formula II R3(EO)n(PO)mOH (II) wherein R3 is an alkyl, alkenyl or arenyl group having from 4 to 22 carbon atoms; a substituted alkyl or alkenyl group having from 4 to 22 carbon atoms wherein; n is a number from 0 to 50 and m is a number from 0 to 10; wherein the mole ratio of epichlorohydrin to (II) is from about 0.60/1 to about 2/1 are extremely efficient defoamers for aqueous surfactant systems. The defoamers are added to a surfactant in an amount sufficient to reduce or eliminate foam and have the advantage of being totally dispersible in water, are readily biodegradable, contain no organic solvents and do not affect the detergency of surfactants with which they are used because they are nonionic surfactants in themselves.Type: GrantFiled: April 14, 1999Date of Patent: October 29, 2002Assignee: Cognis CorporationInventors: Stephen F.

Patent number: 6346554Abstract: 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.Type: GrantFiled: January 18, 2001Date of Patent: February 12, 2002Assignee: Calgon CorporationInventors: Daniel R. Dostie, Roman J. Nowicki
