Publication number: 20090092686Abstract: Disclosed is a process for the recovery of a phytolipid composition from a vegetable oil by-product. The phytolipid composition produced comprises squalene, phytosterols, mixed tocopherols and tocotrieneols, and vegetable wax and is useful as an emollient. The phytochemical composition may be applied directly to the skin to provide emolliency. Alternatively, the phytolipid composition may be formulated in various aqueous or anhydrous cosmetic compositions such as creams, lotions, gels, ointments, lip balms, sticks, or pencils for treatment of the skin and lips. The phytolipid composition also may be incorporated into foods, beverages, and nutraceuticals to provide health benefits.Type: ApplicationFiled: December 12, 2008Publication date: April 9, 2009Applicant: Eastman Chemical CompanyInventors: George Chester Zima, Terry Ann Oldfield, Suzanne Winegar Dobbs, Phillip Michael Cook, Charles Everette Kelly, Mary Caraway Crow, Craig Alan Hoyme

Patent number: 6800771Abstract: The invention relates to stabilized amido acid compositions. More particularly, the invention relates to compositions of amido acids, such as 6-nonanoylamidohexanoic acid, stabilized with antioxidants. The stabilized amido acid compositions are useful in the manufacture of bleach activators such as sodium nonanamidohexanoyloxybenzenesulfonate. Bleach activators made from the stabilized amido acids of the invention are capable of possessing improved coloration.Type: GrantFiled: September 3, 2003Date of Patent: October 5, 2004Inventors: Dale Elbert Van Sickle, George Chester Zima, Jeffrey Scott DuPont, Robert Richard Dykstra

Patent number: 6527690Abstract: The invention relates to a process for purifying and decolorizing a phenyl ester salt. The process combines a phenyl ester salt with a solvent to form a mixture and then stirs the mixture to form a slurry. The phenyl ester salt is substantially insoluble in this solvent. The process then collects the phenyl ester salt from the slurry. The collected phenyl ester salt may then be optionally dried or recrystallized. The collected phenyl ester salt is dissolved in a solvent to form a solution. The solution is decolorized and then spray dried to form a powder of the phenyl ester salt. As a result of the process the phenyl ester salt powder has a higher purity and an improved color as compared to the starting phenyl ester salt.Type: GrantFiled: June 4, 2001Date of Patent: March 4, 2003Inventors: Bhaskar Krishna Arumugam, Michael Eugene Burns, Dimmick Lee Bymaster, Jeffrey Scott DuPont, Robert Richard Dykstra, Robert Lee Eagan, Eddie Joseph Eckart, Jarvey Eugene Felty, Jr., Kevin John Fontenot, Jeffrey William Green, Shane Kipley Kirk, Gary Paul Lutz, Tony Lee Sander, Thomas Hugh Williams, George Chester Zima

Patent number: 5717118Abstract: The present invention relates to a one-step process for preparing amido-carboxylic acid esters having the amide nitrogen positioned between two carbonyl carbons by reacting a carboxylic acid or carboxylic acid ester with a monohydric alcohol and either a lactam, amino-carboxylic acid or a polymeric amino-carboxylic acid. In this process, amidation, esterification, alcoholysis, and hydrolysis reactions occur simultaneously.Type: GrantFiled: September 5, 1995Date of Patent: February 10, 1998Assignee: Eastman Chemical CompanyInventors: Gary Paul Lutz, George Chester Zima, Thomas Hugh Williams

Patent number: 5650527Abstract: This invention relates to a process for preparing amido ester compounds. The process involves (I) forming a mixture in a reactor of a phenol derivative and an amido-carboxylic acid at a temperature which ensures at least partial solubility of the phenol derivative and the amido-carboxylic acid, and (II) adding a carboxylic anhydride incrementally to the mixture formed in Step (I) while distilling a by-product carboxylic acid from the reactor. The amido esters are useful as bleach activators.Type: GrantFiled: June 5, 1995Date of Patent: July 22, 1997Assignee: Eastman Chemical CompanyInventors: Gary Paul Lutz, George Chester Zima, William Charles Dickason
