Latest Patents
Weissen's latest patents include innovative formulations and processes. One of his notable inventions is the "Use of alkoxylated sugar esters in liquid aqueous softening compositions." This invention relates to specific aqueous compositions that comprise alkoxylated sugar esters, which are characterized by a molar ratio of alkoxy units to hydroxy groups of the unmodified sugar from 1:4 to 3:1. Additionally, the molar ratio of ester groups to hydroxy groups of the unmodified sugar ranges from 0.25 to 0.70, with an HLB value below 8, preferably from 1-3. These alkoxylated sugar esters are often combined with performance boosters selected from cationic and non-ionic compounds to enhance their softening performance.
Another significant patent is the "Process for the preparation of quaternary diesters." This invention outlines a process for creating quaternary diesters of a specific formula, where various alkyl and hydroxyethyl groups are utilized. The process allows for the formation of compounds that can be linked together to create larger alkylene groups, which may be interrupted by nitrogen or oxygen atoms.
