CamphorN/A1,7,7-trimethylbicyclo[2.2.1]heptan-2-one76-22-2C10H16O152.23White or transparent waxy substancePlasticizer. Burn rate modifier
DiphenylamineDPAN-Phenylaniline122-39-4C6H5NHC6H5169.23Colorless, tan, amber, or brown crystalline solid with a pleasant, floral odorUsed in single-base propellants in amounts not exceeding 1%. Incompatible with Nitroglycerin, so it is not used in double-base and triple-base propellant compositions. Milspec MIL-D-98A

2,4-DinitrotolueneDNT1-methyl-2,4-dinitrobenzene121-14-2C6H3CH3(NO2)2182.130Orange-yellow crystalline solid with a characteristic odorTNT precursor (2nd of the 3-stage nitration of toluene). Burn rate deterrent. Used as a stabilizer in single-base propellants. Ballistic modifier (homogenizer) in single-base propellants. Frequently used with dibutyl phthalate. Being phased out due to high toxicity. Suppresses antibody production in humans. Milspec MIL-D-204A

2-NitrodiphenylamineNDPA2-Nitro-N-phenylaniline119-75-5C12H10N2O2214.224Red-brown crystalline powder or reddish-brown solidFunctions by binding nitrocellulose degradation products (e.g. NO, NO2, and nitric acid). Amounts higher than 2% degrade the propellant's ballistic properties. Milspec MIL-N-3399B

Methyl diphenylurea was originally named Centralite for the Center for Scientific-Technical Research in Neubabelsberg Germany. With the increased use of ethyl diphenylurea the methyl was renamed Centralite II with the ethyl named Centralite I. Milspec MIL-M-19719A
