  • Publication number: 20150376118
    Abstract: Fatty amide compositions and their derivatives are disclosed. The fatty amides comprise a reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a primary or secondary amine. Derivatives made by reducing, quaternizing, sulfonating, alkoxylating, sulfating, and sulfitating the fatty amide are also included. The amine reactant can be diethylenetriamine or (2-aminoethyl)ethanolamine, which provide imidazoline amides or esters, respectively. In one aspect, the ester derivative of the C10-C17 monounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin. The compositions are valuable for cleaners, fabric treatment, hair conditioning, personal care, antimicrobial compositions, agricultural uses, and oil field applications.

  • Publication number: 20150361292
    Abstract: A film may be formed from film forming compositions which comprise at least one carboxamide based coalescing solvent. These coalescing solvents impart equivalent or improved wet-scrub resistance, block resistance, gloss, dirt pick-up resistance and leveling characteristics to the films on a substrate, without contributing to total VOC levels, when replacing conventional coalescing solvents. The present invention also includes a method for forming a film comprising applying a film forming composition comprising polyunsaturated reactive carboxamides to a substrate and curing the film under ambient conditions. The coalescing carboxamide solvents are suitable for paint, latex based caulk, adhesives and floor care applications.

  • Publication number: 20150087724
    Abstract: 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.

  • Publication number: 20150087521
    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.
