Abstract: Alkyl lactyllactate and alkoxylated alkyl lactyllactate compounds that are useful as solvents in a variety of applications are disclosed. The compounds are derived from a hydroxyl containing compound and a lactide or lactic acid source that has a specific chirality. The alkyl lactyllactate and alkoxylated alkyl lactyllactate compounds are particularly suitable for use as solvents in applications requiring cold tolerance performance without inclusion of additional volatile components.

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.
