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. The derivatives and sulfate compositions are valuable for many end-use applications, including, for example, agricultural dispersants, water-soluble herbicides, anionic emulsifiers for agricultural use, hard surface cleaners, light-duty liquid detergents, personal cleansers, gas well foamers for oilfield applications, laundry detergents, enhanced oil recovery compositions, latex paints, and specialty foams.

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-Cmonounsaturated acid or its ester derivatives. In particular, the secondary surfactant is selected from Camidoamines, quaternized Cor Camidoamines, Camidoamine oxides, Csulfobetaines, Camidoamine sulfobetaines, and Calkanolamides. The detergents noted above rival or outperform commercial baselines in standard foam tests for liquid detergents, particularly those used for dishwashing.
