Abstract: Aqueous hard surface cleaner compositions useful for removing permanent ink are disclosed. The compositions comprise 75 to 99 wt. % of water; 0.1 to 5 wt. % of a monoterpene; 0.1 to 5 wt. % of a C10-C17 fatty acid derivative; and 0.1 to 5 wt. % of one or more surfactants. The fatty acid derivative is selected from N,N-dialkyl amides, N,N-dialkyl esteramines, and N,N-dialkyl amidoamines. Preferably, a base such as sodium carbonate or monoethanolamine is also included. The invention includes concentrates comprising the non-aqueous components recited above, as well as other applications for the cleaners and concentrates such as graffiti removers and permanent ink erasers. The combination of a monoterpene and certain fatty acid derivatives, especially fatty N,N-dialkyl amides, unexpectedly enables even dilute aqueous compositions to rapidly decolorize black permanent marker from hard, non-porous surfaces.

Abstract: Alkoxylated fatty ester compositions are disclosed. In one aspect, the compositions comprise a reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with one or more alkylene oxides in the presence of an insertion catalyst to give an alkoxylated fatty ester. In another aspect, the metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or its ester derivative is reacted with a glycol ether or a glycol ether alkoxylate, to give an alkoxylated fatty ester. In yet another aspect, the metathesis-derived C10-C17 monounsaturated acid or octadecene-1,18-dioic acid is reacted with one or more alkylene oxides to give a fatty acid alkoxylate, followed by etherification of the fatty acid alkoxylate.

Abstract: Quaternary ammonium, betaine, or sulfobetaine compositions derived from fatty amines, wherein the fatty amine is made by reducing the amide reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives and a secondary amine, are disclosed. Quaternary ammonium, betaine, or sulfobetaine compositions derived from fatty amidoamines, wherein the amidoamine is made by reacting of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives and an aminoalkyl-substituted tertiary amine, are also disclosed. The quaternized compositions are advantageously sulfonated or sulfitated. 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 quaternary ammonium, betaine, and sulfobetaine compositions and their sulfonated or sulfitated derivatives are valuable for a wide variety of end uses, including cleaners, fabric treatment, hair conditioning, personal care (liquid cleansing products, conditioning bars, oral care products), antimicrobial compositions, agricultural uses, and oil field applications.

Abstract: Aqueous hard surface cleaners and concentrates are disclosed. In one aspect, the cleaners comprise water, a monounsaturated C8-C14 fatty N,N-dialkylamide, and at least one anionic, cationic, nonionic, or amphoteric surfactant. The cleaners have a pH within the range of 6.0 to 9.0. Dilutable hard surface cleaner concentrates comprising the monounsaturated N,N-dialkylamide and a surfactant are also disclosed. Also included are aqueous hard surface cleaners which comprise a monounsaturated N,N-dialkylamide, and which by measure of ASTM D4488-95 A5 soil, provide superior percent cleaning at a pH less than 10 than they do at pH 10 and higher. Surprisingly, when a monounsaturated C8-C14 fatty N,N-dialkylamide is included in the aqueous hard surface cleaner or concentrate, rapid and thorough cleaning performance can be achieved even at relatively neutral pH. Consequently, the hard surface cleaners are effective on greasy soils, including baked-on soils, despite their low alkalinity.

Abstract translation: 公开了水性硬表面清洁剂和浓缩物。 一方面，清洁剂包括水，单不饱和C8-C14脂肪N，N-二烷基酰胺和至少一种阴离子，阳离子，非离子或两性表面活性剂。 清洁剂的pH值在6.0至9.0的范围内。 还公开了包含单不饱和N，N-二烷基酰胺和表面活性剂的可稀释的硬表面清洁剂浓缩物。 还包括含有单不饱和N，N-二烷基酰胺的水性硬表面清洁剂，并且通过测量ASTM D4488-95 A5土壤，在比pH10和更高的pH小于10的pH下提供优异的百分比清洗。 令人惊奇的是，当含水硬质表面清洁剂或浓缩物中包含单不饱和C8-C14脂肪N，N-二烷基酰胺时，即使在相对中性的pH下也能实现快速彻底的清洗性能。 因此，硬表面清洁剂对油腻的土壤（包括烤土壤）有效，尽管它们的碱度低。

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.

Abstract: A method of mitigating the formation of 1,4-dioxane and precursors of 1,4-dioxane in alkyl ether sulfate surfactants is disclosed. The method involves adding one or more alcohol, hydrotrope or anti-oxidant additives to an aqueous solution of alkyl ether sulfate surfactant having at least two ethylene oxide groups. The alcohol, hydrotrope, or anti-oxidant is added to the alkyl ether sulfate solution in an amount effective to reduce the formation of diethylene glycol monosulfate, a precursor of 1,4-dioxane, and also reduce the formation of 1,4-dioxane.

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.
