Methods and systems for reducing the volume of polystyrene foam wherein a foam reducing agent is applied to the foam, the foam reducing agent in some embodiments comprising a branched dibasic ester blend.

Systems and methods for polystyrene foam recycling using branched dibasic esters

A stable polysaccharide particle suspension composition comprising: a carrier; an activator solvent comprising a) at least one dibasic methyl or ethyl ester; b) at least one compound of the formula ROOC-A-CONRR(IIa), wherein Rrepresents a C-Calkyl group; wherein Rand Rindividually represents a C-Calkyl group, wherein Rand Rcan optionally together form a ring; and wherein A is a linear or branched divalent C-Calkyl group; or c) a combination a) and b); an organo clay compound; and optionally, a surfactant; the composition being stable and capable of suspending polysaccharide particles. Slurries of polysaccharide particles in such suspension composition and methods of making the compositions and the slurries.

Polysaccharide slurries with environmentally friendly activator solvents

An auto-emulsifying cleaning composition capable of emulsifying upon contact with water, the composition in one typical embodiment comprising, based on the total weight of the composition, (a) from about 1% to about 99% by weight a blend of dibasic esters; (b) from about 1% to about 40% by weight of a blend of surfactants consisting of an organic anion neutralized with an organic cation, where either or both of the anion and the cation have surfactant properties, and the complex of which is soluble in the dibasic ester solvent blend. The blend of surfactants is typically a cationic surfactant and an anionic surfactant, which may or may not be used in conjunction with non-ionic surfactants. The dibasic esters are be derived from a blend of adipic, glutaric, and succinic diacids, and, in one particular embodiment, the blend comprises dialkyl adipate, dialkyl methylglutarate and dialkyl ethylsuccinate, wherein the alkyl groups individually comprise a C-Chydrocarbon group.

Auto-emulsifying cleaning systems and methods for use

A heavy oil cleaning composition comprising: a) a blend of dibasic esters comprising dialkyl methylglutarate and at least one of a dialkyl adipate or dialkyl ethylsuccinate; b) at least one terpene; and c) at least one surfactant. Also described are methods for delivering a solvent at reduced concentration comprising the steps of: a) obtaining a terpene-based solvent; and b) mixing the terpene-based solvent with a carrier fluid (the carrier fluid comprising a microemulsion of i) a blend of dibasic esters selected from the group consisting of dialkyl methylglutarate, dialkyl adipate, dialkyl ethylsuccinate, dialkyl succinate, dialkyl glutarate and any combination thereof, ii) at least one surfactant selected from the group consisting of a terpene alkoxylate, an alcohol alkoxylate and any combination thereof; and iii) water) in order to obtain a mixture to clean heavy oils.

Dibasic esters utilized as terpene co-solvents, substitutes and/or carriers in tar sand/bitumen/asphaltene cleaning applications

A coalescent composition for coating compositions such as paints, adhesives, and coatings comprising a blend of dibasic esters, specifically (i) esters of adipic, glutaric, and/or succinic diacids and/or (ii) esters of isomers of adipic acid have advantages, including efficiency and low VOC.

Low VOC coalescing agents

An environmentally-friendly cleaning composition for industrial and consumer applications comprising (a) a blend of dibasic esters, (b) one or more surfactants (c) and, optionally, (d) water or a solvent. The dibasic esters are be derived from a blend of adipic, glutaric, and succinic diacids, and, in one particular embodiment, the blend comprises dialkyl adipate, dialkyl methylglutarate and dialkyl ethylsuccinate, wherein the alkyl groups individually comprise a C-Chydrocarbon group. The one or more surfactants are typically chosen from alcohol alkoxylate, an alkyl phenol ethoxylate, a terpene, a terpene alkoxylate or any derivates thereof. Optionally, additional components or additives including delaminates such as pinene and d-limonene, fragrances, whiteners, stabilizers, thickeners and the like can be added to the composition. The industrial or consumer application selected from the group consisting of a graffiti cleaner, a painted-substrate cleaner, an ink cleaner, a metal substrate cleaner, a plastic substrate cleaner, an environmentally friendly cleaner, a stain-spot cleaner, an industrial hand cleaner, a resin cleaner, a tar resin cleaner, a textile cleaner, a paint stripper and any combination thereof.

Cleaning compositions incorporating green solvents and methods for use

A coalescent composition for coating compositions such as paints, adhesives, and coatings comprising a blend of diesters, the blend comprising adducts of alcohol and diacids, the alcohol selected from the group consisting of ethyl, propyl, isopropyl alcohol and mixtures thereof, and the diacids selected from the group consisting of a blend of adipic, glutaric and succinic diacids ('AGS') and a blend of adipic, methylglutaric, and ethylsuccinic diacids ('MGA'), and paint, adhesive, and coating compositions comprising such coalescent compositions are disclosed.
