摘要:
The present invention relates to fuel additives, fuel compositions and methods of manufacture in which the additives are provided to impart desired properties to fuels. These properties include, without limitation, reduction of nitrogen oxide and particulate emissions from the exhaust stream of internal combustion engines using the fuels. Preferred embodiments of an additive form of the composition include a nitrogen-containing compound selected from the group consisting of urea, cyanuric acid, triazine, ammonia and mixtures thereof, a carrier blend comprising an alkoxylated alcohol, a polyalkylene glycol ester and an alkanolamide and water. The additive may be provided in a concentrate form by addition of a solvent or may be provided as a final form fuel composition. A method of additive manufacture and is disclosed.

The disclosure involves a novel amine ether acid salt surfactant. The amine constituent of the surfactant may include ether amines or fatty-based amines. The ether acid constituent of the surfactant, in particular, imparts liquidity to the surfactant. Hydrophobic regions may be included on both the amine and ether acid enhancing the surfactancy of the composition. The novel surfactant is versatile and is useful in many different applications.

The disclosure is directed to polyalkoxylated amines used as foam stabilizers and a method for cleaning in which foam produced by a detergent composition is maintained for an extended period of time. Detergent compositions including the new foam stabilizers are also disclosed as are methods for detergent foam stabilization. The new foam stabilizers build or enhance foaming and are particularly useful because of their surprisingly mild, non-skin-irritating characteristics. Mildness is a requirement of components to be included in or used in applications such as liquid dish detergents, hand cleaners and car washes.
