摘要:
A mixture of citric acid esters of ethoxylated alcohols wherein the residue of the alcohol contains from 12 to 18 carbon atoms ethoxylated with from 5 to 9 ethoxy groups and a ratio by weight of monoester to diester in the mixture of citric acid esters in a range of 3:1 to 10:1. The mixture contains less than 10% by weight of unesterified citric acid. The citric acid ester mixture provides improved foaming ability and reduced lachrimatory properties when compared to citric acid esters containing a different ratio of monoester to diester and containing longer or shorter chain length alcohol residues.

摘要:
A process for reducing the content of free formaldehyde and formic acid in nonionic and anionic surfactants is provided. The process comprises adding an amine compound selected from the group consisting of a) alkanolamines, b) aminocarboxylic acids and c) oligopeptides to a surfactant comprised of a member selected from the group consisting of nonionic and anionic surfactants. The amine compound is preferably selected from the group consisting of a) an alkanolamine containing 2 to 15 carbon atoms, b) an aminocarboxylic acid containing 2 to 8 carbon atoms, and c) an oligopeptide with an average molecular weight of 500 to 5000. The nonionic and anionic surfactants preferably contain 1 to 100 ethylene oxide units in the form of at least one polyethylene glycol chain. The amine compound is preferably added in a quantity of 50 to 6000 ppm, based on active substance of said surfactant.
