ABSTRACT:
Smoke-producing compositions are disclosed that combine the low toxicity of an organic acid smoke and the high obscuration effect of a red phosphorus (RP) smoke. Phosphoric acid produced by RP is neutralized by an acid scavenger added to at least one of the RP or organic acid smoke formulations. To prevent chemical reaction between ingredients of the two smoke-producing formulations, they are separated in the apparatus of the present invention such that only the resulting smokes mix. Very small amount of a RP smoke formulation increases the obscuration index of organic acid smokes comparable to conventional hygroscopic chloride (HC) smokes.
