Abstract: The invention provides the use of a surfactant as a corrosion inhibitor, wherein the surfactant is selected from derivatives of alkyl polyglucosides and derivatives of terpene alkoxylates, and mixtures thereof, provided that the derivatives are not sulfosuccinates. Also provided is a method of preventing or reducing corrosion of a metal component that is in contact with, or will be in contact with, an aqueous fluid, wherein the method comprises providing a surfactant and applying the surfactant to the metal component or adding the surfactant to the aqueous fluid that is in contact with, or will be in contact with, the metal component, wherein the surfactant is selected from derivatives of alkyl polyglucosides and derivatives of terpene alkoxylates, and mixtures thereof, provided that the derivatives are not sulfosuccinates.

Abstract: A method for treating an inorganic slurry to preserve the slurry against bacterial contamination, including (I) providing a slurry in a substantially homogeneous phase, and then (II) adding to the slurry an effective amount of a composition containing: (a) a tetrakis(hydroxyorgano)phosphonium salt selected from the group consisting of tetrakis(hydroxymethyl)phosphonium sulphate, tetrakis(hydroxymethyl)phosphonium chloride, tetrakis(hydroxymethyl)phosphonium phosphate, tetrakis(hydroxymethyl)phosphonium nitrate and tetrakis(hydroxymethyl)phosphonium oxalate; and (b) a dispersant selected from the group consisting of (i) a phosphonated compound containing at least one tertiary nitrogen atom and (ii) a homopolymer of an unsaturated acid; and (III) preserving the slurry against bacterial contamination, while avoiding instantaneous heterogeneous thickening of the slurry due to the tetrakis(hydroxyorgano)phosphonium salt.
