| titleOfInvention | Solid compositions containing amine oxide-maleic acid salts |
| 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° 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 unit 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. |
