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.
