A method of degrading 1,4-dioxane in the wastewater produced during the manufacture of alkyl ether sulfates is disclosed. The method includes the steps of (a) mixing from 100 to 10,000 ppm, preferably 1,000 to 4,000 ppm of ozone with the wastewater; (b) introducing HOinto the wastewater in an amount of 0.01 to 10, preferably 0.1 to 0.5 molar equivalents of HOto ozone, and (c) mixing the ozone, HO, and wastewater to generate hydroxyl radicals reactive with the 1,4-dioxane, without the addition of a metal catalyst. The hydroxyl radicals react with the 1,4-dioxane and degrade it into carbon dioxide, water and/or carbonate. The method is effective to reduce a concentration of 1,4-dioxane in the wastewater from a range of about 10 ppm to about 1000 ppm of dioxane down to less than 5 ppb of 1,4-dioxane after treatment. The method is also effective for removing hydrocarbon species that may be present in the wastewater.

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.

A server may assign a temporary phone number and an extension number to a shipment. The temporary phone number may be based on a geographic location of where the shipment is to be delivered. The extension number is associated with the shipment. The temporary phone number and extension number may be included on a shipping label rather than the user's phone number. During the delivery of the shipment, a delivery person may encounter a delivery issue, such as needing directions. The delivery person may call the temporary phone number and extension number and be connected to a user device. The delivery person may communicate the delivery issue, such as asking for directions to the user's residence. Upon delivery of the shipment, the server disassociates the temporary phone number and the extension number from the shipment.

System and method for protecting user information that is associated with a shipment

A security and maturity service is provided to generate a security score for an application. A set of data points are obtained, the data points indicating application information for an application. The data points may be associated with a particular axis of a plurality of axes defined by a scoring model. Furthermore, the scoring model may define a score for each axes based at least in part on the data points. A security score for the application may then be determined based at least in part on the score for the plurality of axes.

A browser or browser component queues touch events on a user device while an associated network page is being rendered. The browser may store a detected touch event, a location of the touch event, and/or a vector associated with the touch event in a touch events queue implemented by a data repository. The browser may also visually indicate that the touch event has been registered. Once the network page is at least partially interactive, the browser may retrieve the touch event information from the touch events queue and apply the touch event. Prior to or after applying the touch event, the visual indicator that alerts the user that the touch event was registered may be removed. The browser may then re-render and display the network page after the touch event has been applied.

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.

A system sends a request for access to a resource and receives a digital certificate in response to the request. The system simultaneously causes one or more computing devices located in different geographical locations to send a plurality of requests to also access the resource. In response to the plurality of requests, digital certificates are received. The digital certificate is then compared to the plurality of digital certificates received from the plurality of requests sent by the computing devices in different geographical locations. The result of the comparison indicates whether the digital certificate is trustworthy.

Fatty amide compositions and their derivatives are disclosed. The fatty amides comprise a reaction product of a metathesis-derived C-Cmonounsaturated 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 C-Cmonounsaturated 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.

Surfactant compositions comprising an alkoxylate, a sulfate, or ether sulfate of a C-Cmonounsaturated alcohol are disclosed. The alkoxylate, sulfate, or ether sulfate may derive from undecylenic acid or undecylenic alcohol. Compared with their saturated analogs, the monounsaturated alkoxylates, sulfates, and ether sulfates are less irritating, making them valuable for personal care, laundry, cleaners, and other household applications. Microscopy studies show that the alkoxylates, sulfates, and ether sulfates have favorable phase behavior over a wide range of actives levels, expanding opportunities for products with greater compaction. When combined with cationic surfactants, the alkoxylates, sulfates, and ether sulfates exhibit synergy, and they have improved solubility compared with their saturated analogs. The surfactants find value for the personal care, laundry and cleaning, emulsion polymerization, agricultural products, oilfield applications, and specialty foams industries.

Surfactants based on monounsaturated fatty alcohol derivatives

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 C-Cfatty 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.
