Fuel additive compositions having at least one acylated detergent, at least one Mannich detergent, and at least one polyether and/or polyetheramine. The acylated detergent may be the reaction product of a hydrocarbyl-substituted acylating agent and a nitrogen containing compound having at least one amino group, that may optionally be quaternizable, and at least one oxygen or nitrogen atom capable of reacting with the hydrocarbyl-substituted acylating agent. The compositions are useful for reducing the formation of carbonaceous deposits and/or cleaning carbonaceous deposits in an engine, such as a gasoline direct injection engine.

The present invention is directed to vapor suppression of liquids through disposing a layer of surfactant onto the surfaces of liquids for surfactants having a density greater than the liquid and regardless of surface tension spreadability issues, and compositions comprising the surfactants in aerosolized form.

The present invention provides kits and compositions for e.g., hypergolic ignition of rocket propellant. The disclosed kits and the compositions comprise inter alia a fuel, a gelling agent, and an ignition agent; wherein the ignition agent is stably dissolved within the fuel.

The invention provides dispersions comprising I) at least one oil-soluble polymer effective as a cold flow improver for mineral oils, II) at least one organic, water-immiscible solvent, III) a dispersant comprising, based on the total amount of dispersant, a) 10-90% by weight of a salt of an ethercarboxylic acid and b) 90-10% by weight of a nonionic surfactant, IV) water and V) at least one organic, water-miscible solvent.

Described herein are compositions for modifying fuels. The modified fuels are more efficient when compared to conventional fuels such as gasoline. Additionally, the modified fuels burn more efficiently and produce fewer emissions. Finally, the modified fuels also do not require any modifications to existing engines.

An industrial fluid is disclosed. The fluid comprises an oleaginous component, an aqueous component, and a surfactant. Substantially all of the surfactant is bound within micelles of the oleaginous component. This results in there being substantially no unbound surfactant present in the fluid. The industrial fluid is also substantially flee from insoluble defoamers or anti-foam compounds.

An industrial fluid is disclosed. The fluid comprises an oleaginous component, an aqueous component, and a surfactant dispersed in the aqueous component. The average micelle diameter follows a Gaussian distribution having a mean, , and wherein the standard deviation is less than or equal to 0.2. The industrial fluid is also substantially free from defoamers or anti-foam compounds.

An industrial fluid is disclosed. The fluid comprises an oleaginous component, an aqueous component, and a surfactant dispersed in the aqueous component.
