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: Processes for making reactive surfactants are disclosed. In one such process, a fatty epoxide, a glycidyl ether, or a combination thereof is reacted with an olefin-functional nucleophile to produce an olefin-functional hydrophobe. The olefin-functional hydrophobe is reacted with ethylene oxide, propylene oxide, butylene oxides, or a combination thereof to produce an alkoxylate. Optionally, the alkoxylate is converted to the corresponding sulfate, phosphate, or maleate. Surfactant compositions comprising the reactive surfactants made by these processes are also described. The invention includes polymerizable mixtures comprising an acrylic monomer and the surfactant compositions as well as aqueous acrylic latex emulsions and coatings produced from the emulsions. The reactive surfactants deliver stable latex emulsions with reduced tendency for surfactant migration or excessive foaming. Coatings from the emulsions have improved wet adhesion, scrub resistance, and water resistance.

Abstract: Dilutable concentrates useful for hard surface cleaners with improved film/streak performance on high-energy surfaces are disclosed. The concentrates comprise a nonionic alkoxylated surfactant and a polyetheramine. A relatively minor proportion of a polyetheramine can resolve film/streak issues that characterize hard surface cleaners formulated with nonionic surfactants. The efficacy of polyetheramines for improving film/streak performance of hard surface cleaners formulated with nonionic alkoxylated surfactants far exceeds the benefits available from known improvements, such as the use of hydrotropes. Other inventive dilutable concentrates and hard surface cleaners comprise an amine-functional hydrophobe and an auxiliary surfactant. Still other dilutable concentrates or hard surface cleaners comprise a nonionic alkoxylated surfactant and lactic acid. An improved method for measuring film/streak properties of hard surface cleaners is also disclosed.
