The present invention is directed to a novel, low-toxicity red smoke generating composition and a method of making the same, comprising at least one red dye, a coolant, an oxidizer, a non-sugar binder, and a non-sulfur particulate fuel that is also a burn-control agent having at least one particle size distribution. Preferably, the red dye comprises an anthracene or anthraquinone-based dye and the fuel comprises a sugar or mixture of sugars.

Low toxicity, environmentally friendly red smoke generating composition and method of making the same

The present invention is directed to a novel, low-toxicity and environmentally-friendly violet smoke generating composition. The composition comprises a mixture of at least one red dye and at least one blue dye, a coolant, an oxidizer, a binder, and a non-sulfur particulate fuel that is also a burn-control agent having two different particle size distributions. Preferably the fuel comprises a mixture of granulated sucrose and sucrose 10&#xd7;.

Low toxicity, environmentally friendly violet smoke generating compositions and methods of making the same

A mixture and method of creating the mixture includes mixing hexachloroethane, stannous oxide, and aluminum together. The mixture may be loaded into at least one canister. The mixture may be combusted to create a smoke screen. The loading of the mixture into the at least one canister may include pressurized loading at loading pressures in the range of approximately 2300 psi to 3600 psi. The hexachloroethane may include approximately 30-40 parts by weight of the mixture and have a particle size of approximately less than 850 &#x3bc;m. The stannous oxide may include approximately 55-65 parts by weight of the mixture and have a particle size of approximately less than 150 &#x3bc;m. The aluminum may include approximately 5-10 parts by weight of the mixture and have a particle size of approximately less than 45 &#x3bc;m. The mixture is devoid of zinc chloride.
