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 H2O2 into the wastewater in an amount of 0.01 to 10, preferably 0.1 to 0.5 molar equivalents of H2O2 to ozone, and (c) mixing the ozone, H2O2, 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.

Polyester diverting agents for low-temperature oil wells
A hydraulic fracturing method for recovering oil from a low-temperature subterranean oil formation is disclosed. Before, during, or after inducing hydraulic fracturing within the formation, a particulate, degradable polyester diverting agent is introduced into the formation in an amount effective to improve oil production from the formation. The diverting agent is allowed to degrade, and oil is recovered. The diverting agent has a melting point greater than the average temperature of the formation and is selected from: (i) ethylene glycol succinates; (ii) acid-terminated ethylene glycol succinates; (iii) acid-terminated polyglycolic acids; (iv) acid-terminated polylactic acids; (v) mixtures of any of (i) through (iv) with a half acid ester; and (vi) mixtures of polylactic acids or polyglycolic acids with a half acid ester. These easily synthesized classes of particulate polyester diverting agents degrade more effectively than polylactides under the conditions present in low-temperature wells and should help to enhance well productivity.

METHOD FOR BOOSTING BLOCKING RESISTANCE OF WATERBORNE COATINGS
A method for boosting the high-temperature blocking resistance of a cured coating made from a waterborne coating formulation is disclosed. Blocking resistance is boosted by incorporating an additive which comprises an organoamine salt of a non-ethoxylated C4-C15 alkyl phosphate. Also disclosed are waterborne coating formulations and cured coatings produced from the formulation. The coating formulations comprise an acrylic latex, water, a dispersant, a pigment, and the anti-blocking additive. Surprisingly, the organoamine salts demonstrate good wetting properties as well as improved high-temperature blocking resistance, much better water solubility, and easier handling when compared with the corresponding alkali metal or ammonium salts. The additives are cost effective and offer environmental and recoating advantages when compared with the fluorochemicals currently available as anti-blocking additives.
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.

POLYESTER DIVERTING AGENTS FOR LOW-TEMPERATURE OIL WELLS
A hydraulic fracturing method for recovering oil from a low-temperature subterranean oil formation is disclosed. Before, during, or after inducing hydraulic fracturing within the formation, a particulate, degradable polyester diverting agent is introduced into the formation in an amount effective to improve oil production from the formation. The diverting agent is allowed to degrade, and oil is recovered. The diverting agent has a melting point greater than the average temperature of the formation and is selected from: (i) ethylene glycol succinates; (ii) acid-terminated ethylene glycol succinates; (iii) acid-terminated polyglycolic acids; (iv) acid-terminated polylactic acids; (v) mixtures of any of (i) through (iv) with a half acid ester; and (vi) mixtures of polylactic acids or polyglycolic acids with a half acid ester. These easily synthesized classes of particulate polyester diverting agents degrade more effectively than polylactides under the conditions present in low-temperature wells and should help to enhance well productivity.

Compositions comprising at least one esteramine active are disclosed in which the esteramine provides conditioning, softening, and/or cleaning properties. The compositions are useful for hair care, as well as in other applications, such as cleaning compositions, fabric softening compositions, and skin care compositions. Also disclosed are esteramine compositions that comprise a synergistic mixture of at least one esteramine and mono- and di-glycerides that provides better wet and dry combing than either the esteramine or mono- and di-glycerides alone. The synergistic mixture comprises about 50% to about 90% by weight esteramines and about 10% to about 50% by weight mono- and diglycerides.

Polyester polyols for use in low-VOC polyurethane compositions are disclosed. The polyester polyols are the reaction product of at least one aliphatic polycarboxylic acid, at least one alkoxylated polyalcohol having a functionality of 2.0 or greater, and one or more polyalcohols other than an alkoxylated polyalcohol. The polyester polyols can be formulated into polyurethane compositions to obtain a polyurethane having a low VOC content. The polyurethane composition is particularly suitable for polyurethane coating applications.
