Estimating the term…
Unsaturated fatty alcohol alkoxylates, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol alkoxylate is made by reducing a metathesis-derived monounsaturated alkyl ester, followed by alkoxylation of the resulting monounsaturated alcohol. Microscopy reveals that the monounsaturated alkoxylates have isotropic and lamellar phases over a wider range of actives levels compared with their saturated analogs. This attribute expands formulating latitude for many end-use applications. The unsaturated fatty alcohol alkoxylates are valuable in, for example, agricultural solvents, nonionic emulsifiers for agricultural compositions, hard surface cleaners, laundry detergents, specialty foams, additives or surfactants for paints or coatings, and surfactant compositions for enhanced oil recovery.
A fatty alcohol alkoxylate made from a monounsaturated fatty alcohol composition, wherein the fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester.
A monounsaturated fatty alcohol ethoxylate having at least one isotropic clear phase over an increased actives level range when compared with that of a saturated analog of the monounsaturated fatty alcohol ethoxylate.
A process which comprises reducing a metathesis-derived monounsaturated alkyl ester to produce a monounsaturated fatty alcohol composition, and alkoxylating the monounsaturated fatty alcohol composition with one or more alkylene oxides to produce a fatty alcohol alkoxylate.
