The surface properties of amine oxides with a fluoroether chain

Persistent organic pollutants (POPs) includes long-chained fluorosurfactants, for instance, perfluorooctanonate (PFOA) and perfluorooctanesulfonate (PFOS). In order to find out alternative fluorosurfactants, we synthesized eight amine oxides with a fluoroether chain. Their surface properties were evaluated and compared with perfluoroalkyl and hydrocarbon analogues. The surface tensions at critical micelle concentration (γcmc) for the eight amine oxides with a fluoroether chain were at a range from 15.5 to 23.0 mN/m, and γcmc of four fluoroether amine oxides were below 17 mN/m comparable to perfluorooctyl analogues (16.4 mN/m) and much lower than perfluorohexyl (20.5 mN/m) and hydrocarbon analogues (24.2 and 24.7 mN/m). The critical micelle concentration (cmc) for the eight amine oxides with a fluoroether chain were 3 to 535 × 10?4 mol/L. The cmc of four fluoroether amine oxides were 3 to 21 × 10?4 mol/L (0.2 to 1.0 g/L) comparable to perfluorooctyl (0.4 g/L) and hydrocarbon analogues (4 and 10 × 10?4 mol/L) and much lower than perfluorohexyl analogue (36.9 g/L). The surface excesses, the limiting molecule areas and the free energies of micellization of amine oxides were calculated. Fluoroether surfactants are promising alternatives for PFOA and PFOS.

Carboxamide derivative, processes for producing the same, and detergent composition

To provide: a carboxamide derivative having reduced content of amide ester; a method for producing thereof; and a detergent composition containing the carboxamide derivative and having excellent low-temperature stability. One method for producing a carboxamide derivative is to react carboxamide, produced with a manufacturing method of carboxamide including 0.02% by weight to 0.18% by weight of amide ester, with hydrogen peroxide, wherein the method includes a carboxamide synthesis process to synthesize carboxamide by reacting diamine with fatty acid ester at a molar rate of 1.20 to 1.60. Another method for producing a carboxamide derivative is to react the carboxamide with monohaloalkylcarboxylic acid or a salt thereof. A carboxamide derivative is produced by the method for producing a carboxamide derivative. A detergent composition includes the carboxamide derivative. The carboxamide derivative is preferably amidoamine oxide or amide betaine.
