Abstract
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 C10-C17 monounsaturated acid, 5 octadecene-1,18-dioic acid, or their ester derivatives. In another aspect, aqueous hard surface cleaners comprising at least one nonionic or amphoteric surfactant derived from a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives are disclosed. The aqueous cleaners noted above rival or outperform commercial baselines in a Gardner straight-line washability test. Industrial degreasers comprising a C10 or C12 amide solvent and derived from a metathesis-derived C10-C17 monounsaturated acid are superior to commercial standards.
