Aqueous hard surface cleaner compositions derived from metathesized natural oil feedstocks are disclosed. In one aspect, the compositions comprise at least one anionic surfactant derived from a metathesis-derived C-Cmonounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives. Particular classes of sulfonated materials (e.g., certain amide sulfonates, sulfonated fatty ester alkoxylates, amidoamine sulfonates, amidoamine betaine sulfonates, sulfo-estolides) are identified as having value as the anionic surfactants. In another aspect, aqueous hard surface cleaners comprising at least one nonionic or amphoteric surfactant derived from a metathesis-derived C-Cmonounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives are disclosed. Particular classes of these surfactants (e.g., certain amides, imidazoline quat sulfonates, fatty ester alkoxylates, and amine oxides, betaines, amidoamine sulfobetaines) are also identified. The aqueous cleaners noted above rival or outperform commercial baselines in a Gardner straight-line washability test. Industrial degreasers comprising a Cor Camide solvent and derived from a metathesis-derived C-Cmonounsaturated acid are superior to commercial standards. |
