Abstract
Light-duty liquid detergents derived from metathesized natural oil feedstocks are disclosed. The detergents comprise water, at least one anionic surfactant, and at least one secondary surfactant derived from a metathesis-derived C10-C17 monounsaturated acid or its ester derivatives. In particular, the secondary surfactant is selected from C10 amidoamines, quaternized C10 or C12 amidoamines, C12 amidoamine oxides, C12 sulfobetaines, C12 amidoamine sulfobetaines, and C12 alkanolamides. The detergents noted above rival or outperform commercial baselines in standard foam tests for liquid detergents, particularly those used for dishwashing.
