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. 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.

Abstract: Agricultural compositions that employ structured surfactant systems to suspend water-insoluble or sparingly soluble agricultural actives and/or adjuvants are disclosed. Also disclosed are agricultural compositions that combine structured surfactant systems with electrolytes to form structured electrolyte compositions. The structured surfactant systems, both with and without electrolyte, suspend one or more agricultural actives and/or crop oil and non-aqueous adjuvants to provide agricultural compositions that can combine combinations of actives in a single, stable composition.
