Abstract: Aqueous liquid dishwashing detergent compositions are prepared that exhibit improved detergency performance and foam stability over a range of water hardness levels. A preferred formulation incorporates a three component mixture: an anionic surfactant, a nonionic surfactant, and an amido amine oxide to provide a detergent having good detergency performance and foam stability over a range of water hardness levels. Another preferred formulation incorporates a three component mixture: an anionic surfactant, a nonionic surfactant, and an alkyl ethoxylated carboxylate to provide a detergent having good detergency performance and foam stability at high hardness levels.

Abstract: The physical stability of liquid gel-like compositions based on thixotropic thickener is greatly improved by incorporating in the composition small amounts, such as 0.1 to 0.2 weight percent of long chain fatty acids and salts thereof. The aqueous compositions containing inorganic builder salts and other functional inorganic salts, chlorine bleach, bleach stable detergent, at least one thixotropic thickener and a fatty acid or alkali metal salt of the fatty acid as a physical stabilizer exhibit a significant increase in apparent viscosity and remain stable against phase separation for an extended period of time. The thixotropic properties can be retained or improved using smaller levels of the thixotropic thickener than in the absence of the physical stabilizer. The stability, chlorine-bleach loss and cleaning ability of the compositions is further improved, when the composition pH is at least 11.2, when added to an aqueous wash both at a concentration of about 10 grams per liter.

Abstract: Disclosed are solid, concentrated, amine oxide surfactant compositions containing amine oxide- maleic acid salts. The molar ratio of maleic acid to amine oxide in such salts is about a 1:1. The salts are soluble in water at 25.degree. C. at a pH of above the pKa of the amine oxide. Also disclosed is a process for preparing such solid amine oxide surfactant compositions, which process comprises admixing maleic acid and amine oxide surfactants in at least about a 1:1 molar ratio, at a pH of at least about 1 units less than the pKa of the amine oxide, to thereby form a visible precipitate therein. The precipitate is separated from the mixture, preferably by mechanical means, and dried. The dried precipitate is a maleic acid-amine oxide salt which can be incorporated into cleaning products, especially solid or granular cleaning products, as a solid, concentrated source of amine oxide surfactant.

Abstract: Disclosed is a process for making solid formulations containing amine oxide surfactants. Maleic acid, or a water soluble salt thereof, is admixed with an aqueous liquid amine oxide formulation, which formulation preferably contains from about 20% to about 40% by weight of an amine oxide surfactant. The molar ratio of maleic acid to amine oxide surfactant is at least about 1:1. Admixture pH is maintained at or below, or reduced to at least, about 1 unit below the pKa of the amine oxide to form a visible precipitate therein. The precipitate is separated from the mixture, preferably by mechanical means, and dried. The dried precipitate is a maleic acid-amine oxide salt which can be incorporated into cleaning products, especially solid or granular cleaning products, as a source of amine oxide surfactant.

Abstract: A stable aqueous detergent composition is provided in liquid or gel form containing from 10 to 80% by weight of an active detergent mixture comprising primary alkyl sulphate in an amount of 15 to 75% by weight of the active detergent plus betaine and/or amine oxide in an amount of 10 to 40% by weight of the active detergent mixture. Primary alkyl sulphate having chains of 10 or 11 carbon atoms provides at least 25% by weight of the primary alkyl sulphate present. The betaine and/or amine oxide is at least two thirds of the amount by weight of any primary alkyl sulphate having carbon atom chains of 12 carbon atoms or longer. The C.sub.10 and/or C.sub.11 alkyl sulphate is surprisingly effective as a detergent in such compositions despite higher water solubility than longer chain alkyl sulphate. It can enhance mildness compared to longer chain alkyl sulphate, and can replace or partially replace alkyl ether sulphate. Nonionic detergent may be included to enhance mildness further.

The compositions have a pH of from about 1 to about 5.5, preferably from about 2 to about 4 when the dicarboxylate builder is used. The compositions are in the form of aqueous liquids.
