  • Patent number: 5478554
    Abstract: 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.

  • Patent number: 5034159
    Abstract: Adducts of ethylene oxide and/or propylene oxide with saturated and/or unsaturated C.sub.8-22 fatty alcohols having an average degree of alkoxylation n of 1 to 10, and more especially 1 to 6, are particularly suitable as thickeners for aqueous surfactant solutions when the adducts have a narrow homolog distribution compared with the products obtained by standard methods.

  • Patent number: 4992263
    Abstract: Nitrogen-free thickeners in aqueous surfactant solutions comprising polyethoxylates of mono- and/or polyunsaturated C.sub.12 -C.sub.22 fatty alcohols having an average degree of ethoxylation of 2 to 5, which also contain 1 to 2 terminal propylene oxide groups attached by condensation instead of the corresponding number of ethylene oxide groups. The products may also be used in admixture with dissolved inorganic electroltye salts and with polyethoxylates of saturated fatty alcohols. These surfactant solutions are useful in the formulation of personal hygiene preparations such as hair shampoos, foam baths, shower baths, handwashing pastes and the like.
