ABSTRACT:
A composition which is capable of producing an obscuring white smoke is disclosed which employs a dicarboxylic acid as the primary smoke producing agent. It is found that by using a dicarboxylic acid smoke producing agent, a generally non-toxic and non-corrosive smoke is achieved. Also included within the composition are a binder, a fuel or coolant, and an oxidizer. The binder may be any one of a number of binders such as nitrocellulose or a polymer binder. A low energy fuel is preferred in order to minimize heat and flame produced. Such fuels may include, for example, starch, dextrose, lactose, sucrose, or sulphur. The presently preferred oxidizer is KCLO.sub.3. Other substances may also be added to the composition. For example, sodium bicarbonate may be added to act as a buffer for the KCLO.sub.3 and as a further coolant. In some cases it may also be desirable to add aluminum for purposes of producing more uniform burning and increased thermal conductivity through out the composition.
