Patent number: 7110051Abstract: Provided herein are consumer products contained in conventional containers. A consumer product packaged according to the present invention is one which exhibits birefringence, and the packaging used according to the present invention is arranged so that the consumer product is caused to exist between two layers of polarizing film and is thus capable of exhibiting the phenomenon of birefringence to consumers under ambient lighting conditions.Type: GrantFiled: March 3, 2004Date of Patent: September 19, 2006Assignee: Huntsman Petrochemical CorporationInventors: Raeda M. Smadi, Curtis M. Elsik, Samir S. Ashrawi, George A. Smith, Christopher J. Whewell

Patent number: 7008914Abstract: This invention is directed to a fluorine-containing mordenite catalyst and use thereof in the manufacture of alkylbenzene (LAB) by alkylation of benzene with an olefin. The olefin may have from about 10 to 14 carbons. The fluorine-containing mordenite is prepared typically by treatment with an aqueous hydrogen fluoride solution. The benzene alkylation may be conducted using reactive distillation. This invention is also directed to a process for production of LAB having a high 2-phenyl isomer content by use of the fluorine-containing mordenite in conjunction with a conventional solid LAB alkylation catalyst. The two catalysts may be used in a mixed catalyst bed or may be packed in series, with the relative proportions being adjusted to provide a desired 2-phenyl isomer content of in the final product.Type: GrantFiled: October 3, 2002Date of Patent: March 7, 2006Assignee: Huntsman Petrochemical CorporationInventors: George A. Smith, Prakasa R. Anantaneni, Samir S. Ashrawi, Raeda M. Smadi, John F. Knifton, Melvin Stockton

Patent number: 6995127Abstract: This invention is directed to detergent compositions which employ sulfonated alkyltoluenes as surfactants, wherein the sulfonated alkyltoluenes have a higher content of the sulfonated 2-phenyl alkyltoluenes isomers than was previously available in sulfonated alkyltoluene surfactants of the prior art. Cleaning compositions according to the invention are more effective as cleaning agents over their counterparts of prior art which contain sulfonated alkyltoluenes having lower contents of the 2-phenyl alkyltoluene isomers, owing to an unexpected increase in tolerance of water hardness minerals normally associated with precipitation of the active detergent agent. Solid sulfonate salts of alkyltoluenes are also provided, including dry cleaning formulations containing same.Type: GrantFiled: September 19, 2000Date of Patent: February 7, 2006Assignee: Huntsman Petrochemical CorporationInventors: George A. Smith, Prakasa R. Anantaneni, Samir S. Ashrawi, Raeda M. Smadi

Patent number: 6703033Abstract: Provided herein are moist towelettes useful for cleansing, among other things, hard surfaces and human skin. The moist towelettes of the invention comprise a towelette portion which is moistened with a liquid composition of matter wherein the liquid composition includes an alkylene carbonate as one of its components. According to one preferred form of the invention, the liquid composition from which the towelettes are made moist are alcohol-free. In another embodiment, a substantial portion of the alcohol in a given formulation is replaced with an alkylene carbonate component. Preferred alkylene carbonate components include propylene carbonate, butylene carbonate, and glycerine carbonate.Type: GrantFiled: April 26, 2001Date of Patent: March 9, 2004Assignee: Huntsman Petrochemical CorporationInventors: Raeda M. Smadi, James R. Machac, Jr., Edward T. Marquis

Patent number: 6602839Abstract: Provided herein are sulfosuccinamates made using polyetheramines as intermediates. The sulfosuccinamates according to the invention exhibit excellent detergency when employed in formulations used as hard surface cleaners, laundry detergents, and dishwashing liquids. In addition, the sulfosuccinamates according to the invention have an unexpectedly high degree of water hardness tolerance, and are easier to produce than similar materials found in the prior art owing to the fact that the product and its intermediates exist in liquid form.Type: GrantFiled: January 5, 2001Date of Patent: August 5, 2003Assignee: Huntsman Petrochemical CorporationInventors: George A.
