A mineral-compatible cationic emulsion composition with polymer stabilizers, and methods for utilizing same in paving and other applications is disclosed. In one aspect, a bitumen-in-water emulsion composition includes at least one bitumen material, at least one polymer stabilizer, at least one emulsifier, and water, where the emulsifier is a cationic surfactant, an amphoteric surfactant, or a mixture of both, and the polymer stabilizer is a natural or synthetic cationic polymer consisting of alkylene polyamines, alkyl polyamines, polyquaternary polymers, polyvinylamine, polyvinylimidazoline, polyester polyquaternary polymers, polyether polyquaternary polymers, or mixtures thereof. The inclusion of polymer stabilizer in the cationic emulsion increases the stability of the emulsion and increases the compatibility of the cationic emulsion with negatively charged minerals.

Polymer stabilizers for bituminous emulsions

A method renders the surface of bitumen materials to be non-tacky, and minimize or eliminate the loss of the bitumen materials to traffic. The method may also be used on top of prime coat and fog seal, to reduce tackiness of bitumen materials from cured bitumen emulsions, and to decrease unnecessary and unwanted tracking by passing traffic.

Method for producing bituminous coatings with reduced tackiness

The present invention generally relates to the discovery that a blend of linear and branched amide wax additives can be used to enhance the performance of asphalt binders and asphalt emulsion residues. In particular, high temperature properties of asphalt pavement can be improved while maintaining or improving low temperature properties. The additives also improve workability and lower processing temperatures for asphalt paving (e.g. warm mix) or for roofing. These amide wax additives can reduce the tracking of tack coats, by decreasing binder penetration and forming a non-tacky surface layer.

Performance modifiers for bitumen comprising straight and branched chain fatty amide waxes

The present invention generally relates to a textile softening composition which comprises, as the softening agent, a quaternary ammonium salt which comprises a mixture of mono-, di- and tri-ester components, wherein the amount of diester quaternary is greater than about 50% by weight, and the amount of triester quaternary is less than about 25% by weight based on the total amount of quaternary ammonium salt. The invention also relates to a softening agent which comprises a high diester quaternary ammonium salt mixture comprising mono- and diester components derived for ether dialkanolamines. The invention also relates to processes for preparing said softening agents, and methods of use as a fabric softener and as a hair and skin conditioner.

High di(alkyl fatty ester) amines and quaternary ammonium compounds derived therefrom

A method for controlling the rheology of aqueous systems, particularly for those intended for underground use, includes injecting an aqueous viscoelastic fluid containing a surfactant gelling agent into the system. The viscoelastic surfactant composition of the invention comprises, as a gelling agent, at least one fatty aliphatic amidoamine oxide in a glycol solvent. The composition also maintains the levels of free fatty acid and free amine within critical parameters in order to achieve superior performance. The additives may be incorporated in the viscoelastic fluid to tailor its use in stimulation fluids, drilling muds, fracture fluids, and in applications such as permeability modification, gravel packing, cementing, and the like.

Viscoelastic surfactants and compositions containing same

The present invention generally relates to low foaming and/or defoaming cleaning formulations which, comprises a synergistic combination of one or more hydrotropic alkoxylated quaternary ammonium compounds and at least one nonionic surfactant based on branched alcohols. The nonionic surfactant may be selected from structures having 3 to 12 moles of ethoxylation, but preferably have an average of 3-6 moles of ethoxylation with either narrow or broad range distribution.

High di(alkyl fatty ester) quaternary ammonium compounds in fabric softening and personal care compositions

A 2-in-1 conditioning shampoo includes an anionic surfactant and a cationic hair conditioning agent. The cationic hair conditioning agent is a fatty aliphatic quaternary ammonium compound having ester linkages. The cationic hair conditioning agent can be prepared by reacting an alkanol amine with a fatty acid or fatty acid ester having an aliphatic group of from about 11 to about 24 carbon atoms and thereafter quaternizing the resulting esteramine with an alkylating agent.

Methods for producing carboxylic amides involves combining near-stoichiometric amounts of carboxylic acid and amine in a reaction vessel and reacting under pressures greater than atmospheric pressure. Alternatively, an excess of amine is reacted with carboxylic acid at atmospheric pressure to produce a carboxylic amide.

Viscoelastic surfactant based aqueous fluid systems are described that are useful in fracturing subterranean formations penetrated by a wellbore. The preferred surfactant compositions contain quaternary ammonium salts wherein the long chain alkyl substituent contains about 3% or less of groups containing 18 or less carbon atoms. The amount of intermediate compounds in the surfactant composition is less than about 1%. The surfactant composition can be used in conjunction with an inorganic water soluble salt such as ammonium chloride or potassium chloride, and an organic stabilizing additive.
