  • Patent number: 11760889
    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. Microscopy studies indicate that the unsaturated sodium sulfates in particular have a lamellar phase that should enable formulation at high actives levels. Sulfate compositions comprising 40 to 60 wt. % of a monounsaturated fatty primary alcohol sulfate and 40 to 60 wt. % of a secondary hydroxyalkyl primary alcohol sulfate are also disclosed.

  • Patent number: 9249374
    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.
