Provided herein is a method to reduce the endotoxin contamination in plasmid preparations. In the described method, plasmid DNA and endotoxins are bound to an anionic exchange matrix and are brought into contact with a wash buffer, comprising a combination of branched secondary alcohol ethoxylates with varying ethylene oxide chain lengths, wherein the branched secondary alcohol ethoxylates with the shorter ethoxylate chain is present in the washing buffer in excess compared to the branched secondary alcohol ethoxylate with the longer ethoxylate chain. The resulting purified plasmid has minimal endotoxin contamination levels and is considered endotoxin-free. Furthermore, provided are wash buffers comprising a combination of branched secondary alcohol ethoxylates with varying ethylene oxide chain lengths, kits comprising such wash buffers and the use of such wash buffers for reducing the endotoxin contamination in plasmid preparations.

A liquid hand dishwashing cleaning composition having from 15% to 40% by weight of the composition of a surfactant system. The surfactant system has an anionic surfactant and from 5% to 18.4% of a nonionic surfactant package by weight of the composition. The weight ratio of the nonionic surfactant package to the anionic surfactant ranges from 1:1 to 3:1. The nonionic surfactant has a mixture of a first nonionic surfactant and a second nonionic surfactant. The first nonionic surfactant includes an alkyl polyglucoside surfactant. The surfactant system further includes a co-surfactant. The weight ratio of the anionic surfactant to the co-surfactant ranges from 1:1 to 8:1. The composition is free of fatty acid or salts thereof.
