The fact that there are various additives sometimes added to Jet Fuel often comes up in discussion of the Chemtrail Theory. There's often some debate as to what the additives are, and if they contain barium or aluminum, and how much is added to the fuel. So I'm starting this thread to proved a useful list of these additives, their ingredients and their usage.
First a query, wikipedia says:
http://en.wikipedia.org/wiki/Aluminium_borohydride

UPDATE Aug 4 2019
There are several additives found here:

One of the most frequently mentioned is Prist:

Then there's Hammonds Biobor JF Diesel and Jet Fuel Microbicide - MIL-S-53021A, used for killing bacteria:

Compostion: Substituted dioxaborinanes 95.0% Naphtha 4.5%
Usage 135ppm to 270ppm

And yet the only reference I can find for anything like this is using AB as a chemical ignitor in jet engines, not as an additive to the fuel:Aluminum Borohydride is a volatile pyrophoric liquid which is used as rocket fuel, an additive in jet fuel, and as a reducing agent in laboratories.

The Wikipedia article was corrected back in 2014, and now simply reads:
The note accompanying the change says:Aluminium borohydride, also known as aluminium tetrahydroborate, (in American English, aluminum borohydride and aluminum tetrahydroborate, respectively) is the chemical compound with the formula Al(BH4)3. It is a volatile pyrophoric liquid which is used as rocket fuel, and as a reducing agent in laboratories.
no indication that this compound is used as a jet fuel additive. There is one reference which suggests a possible use as a pyrophoric igniter...)

There's also a low-flo version. Both seem to be 99% volatile hydrocarbons.TRADE NAME: PRIST® HI-FLASH HI-FLO Anti-Icing Aviation Fuel Additive
SYNONYMS: Diethylene Glycol Monomethyl Ether, DEGMME; Methyl Carbitol
MILITARY SPEC MIL-DTL-85470B
CHEMICAL FAMILY: Glycol Ethers
FORMULA: CH3-OCH2CH2O-CH2CH2OH
Note the dosage rate: 0.10% to 0.15% (1 to 1.5 parts in a thousand, or 1,000 to 1,500 ppm). Also note no aluminum or barium.Prist Hi-Flash Hi-Flo Anti-Icing Fuel Additive is less toxic, less volatile and easier to use than conventional additives. It controls icing in aircraft fuel by depressing the freezing point of water, reducing the occurrence of suspended ice crystals and ensuring that fuel will flow freely through lines and filters. Prist Hi-Flash additive is recommended for every refueling at a dosage rate of .10% minimum to .15% maximum by volume. Hi-Flo delivers the product at a rate compatible with a 40 to 55 gal. per minute fuel nozzle rate.When dissolved water separates from the fuel, some amount of Prist Hi-Flash additive quickly leaves the fuel and preferentially dissolves in the water. This depresses the water's freezing point. As the fuel gets colder, and more water particles appear, more Prist Hi-Flash additive leaves the fuel and enters the water, and your aircraft's fuel lines stay clear.
