Patent number: 6620904Abstract: Applicant has discovered processes for preparing polyglycerols and polyglycerol esters in high yield and with minimal formation of cyclic polyglycerols and cyclic polyglycerol esters. Furthermore, the processes of this invention produce a high proportion of linear polyglycerols and polyglycerol esters. The linear polyglycerols have very desirable physical characteristics, including a clear appearance at melt, a desirable Gardner color, a mild odor, and a bland taste. The polyglycerols and polyglycerol esters prepared by the method of the present invention are well suited for use as cosmetic and food additives. Since few, if any, cyclic polyglycerols and polyglycerol esters are formed by the processes of this invention, costly and time consuming distillation steps to remove such by-products are not needed.Type: GrantFiled: November 6, 2001Date of Patent: September 16, 2003Assignee: Lonza Inc.Inventor: Daniel Wayne Lemke

Patent number: 6429181Abstract: The inventors have discovered that partially halogenated hydantoins exhibit superior antimicrobial efficacy and decreased performance additive decomposition rates than fully halogenated hydantoins, such as dichlorodimethyl hydantoin (DCDMH). Partially halogenated hydantoins are solutions containing monochlorohydantoin and, optionally, dihalogenated hydantoin or non-halogenated hydantoin. The present invention is a method of reducing slime in a circulating water slurry comprising organic matter and one or more performance additives, such as optical brighteners, while minimizing decomposition of the performance additives. The method comprises adding one or more partially halogenated hydantoins, such as Cl1.1-chlorodimethyl hydantoin, to the slurry. The concentration of partially halogenated hydantoin maintained in the slurry generally ranges from about 0.01 to about 50 ppm (expressed as Cl2). This method is particularly useful for circulating water slurries in paper processing.Type: GrantFiled: January 30, 2001Date of Patent: August 6, 2002Assignee: Lonza Inc.Inventors: Philip Gerdon Sweeny, Daniel Wayne Lemke, Michael Leonid Ludensky

Patent number: 6117831Abstract: The subject invention relates to a novel class of compounds, known as alkali metal salts of hydroxyalkyl sulfonates of aminoalkyl alkanol amines and/or aminoalkyl alkanol ethers, the methods of making such compounds, the alkali-stable solutions containing such compounds, and the use of said solutions as strong detergent compositions. Those alkali-stable solutions are temperature-stable, exhibit superior wetting characteristics, and can be made into low or high foam formulations useful for hard surface cleaning, oven and grill cleaning, metal cleaning, bottle washing, steam cleaning and wax stripping formulations.Type: GrantFiled: September 3, 1998Date of Patent: September 12, 2000Assignee: Lonza Inc.Inventors: Michael Yao-Chi Chiang, Daniel Wayne Lemke, Joseph William Scheblein

Patent number: 5942627Abstract: A method for producing amphocarboxylpropionate comprising initiating the reaction of methyl acrylate with 2-alkyl imidazoline in the substantial absence of water; adding from 0.3 to 2 moles of water per mole of 2-alkyl imidazoline to the reaction products after at least 1.3 moles of the methyl acrylate reacts with one mole of the 2-alkyl imidazoline, so as to form a reaction product having a molar ratio of at least 1.8:1 of methyl acrylate to imidazoline. The products of the method can be formulated in highly concentrated form and do not have the gelling problems of the prior art formulation. These products are useful and beneficial in personal care products.Type: GrantFiled: March 31, 1997Date of Patent: August 24, 1999Assignee: Lonza Inc.Inventor: Daniel Wayne Lemke
