Abstract:
Sulfate and sulfonate derivatives of unsaturated fatty alcohols, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester. The fatty alcohol composition is then converted to a sulfate or sulfonate derivative by one or more of alkoxylation, sulfation, sulfonation, and sulfitation. Of particular interest are the sulfate and ether sulfate derivatives.
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 C 10 -C 17 monounsaturated acid or its ester derivatives. In particular, the secondary surfactant is selected from C 10 amidoamines, quaternized C 10 or C 12 amidoamines, C 12 amidoamine oxides, C 12 sulfobetaines, C 12 amidoamine sulfobetaines, and C 12 alkanolamides. The detergents noted above rival or outperform commercial baselines in standard foam tests for liquid detergents, particularly those used for dishwashing.
