C-4 (composition 4) is one of the popular plastic explosive(explosive chemical mix with plastic binder). It has 2 important advantages:
Explosive material in C-4 is cyclotrimethylene-trinitramine (royal demolition explosive / RDX). Cyclotrimethylene-trinitramine was first prepared in 1899 from nitric acid and methenamine by Henning. The flow chart below (Please refer to reference below) shows the synthesis method uses methenamine (hexamethylenetetramine).
Besides the method above, cyclotrimethylene-trinitramine can also be synthesized from formaldehyde, ammonium nitrate and acetic anhydride. (Method developed by Ross and Schiessler' in 1940's)
Normally, C-4 is made up of explosives, plastic binder, plasticizer and, usually, marker or taggant chemicals such as 2,3-dimethyl-2,3-dinitrobutane (DMDNB) to help detect the explosive and identify its source. In 2004, Kenneth E. Lee discovered a reformulation of composition C-4 explosive for superior energetic performance and flexibility. (US Patent: 6887324)

C4 is not a compound, but is a mixture of compounds. It consists of an explosive (RDX)- about 91%. The rest is a plastic binder, plasticizer, a taggant to make it detectable, and a small amount of motor oil.
The link below will take you to an article on RDX that shows the chemical structure. For anyone considering trying to MAKE their own C4- it is far more involved than simply mixing the components- and is EXTREMELY hazardous to attempt.
C4's main ingredient (which is mostly the explosive) is the explosive called RDX. The other "main" ingredient is a plastic binder to coat and contain it.
C4 is short for Compound 4, and is the current U.S. standard plastic explosive.
The letter C annd the number 4
An explosive called RDX. The rest is is just a mixture of a plastic binder that protects and contains the explosive.
C4 explosives look like a block of plastic, which is usually solid or transparent-white.
Trytophan
C3 and C4 plants are named after the number of carbon molecules in the first products of their carbon fixation cycles. C3 plants produce 3-phosphoglycerate and C4 plants produce Oxaloacetate.
Most common is nitrogen.
You find yourself with half an ounce less C4 than you started out with.

chickens:) is the main ingrediant in eggs not egg shell just so u peoples know!
shrimp
Oxycodone.
grenades, HE, c4, white phos. etc
Potatoes.
lobster
c4
It was called C-2 or Plastique
c4
i am pretty sure its flour
Cabbage is the main ingredient in sauerkraut.
