Abstract

The invention provides methods and compositions for the reduction of dust in an environment through application to a hard surface in that environment or dispersal of dust into the environment is minimized. The composition allows for instant reduction of dust and for the elimination of the absorption of moisture on surfaces that are prone to this over time. The invention is usable with mined minerals or synthesized materials that are prone to produce dust and absorb moisture during storage and transport so the composition can allow for a safer environment and longer storage of products.

Claims (6)

1. A method of dust control comprising applying a composition onto a surface in an amount effective to allow for the immediate elimination of dust particles and remain effective for an extended period of time, wherein the composition comprises a transport component, a dispersant, a surface modifying agent, and one or more phospholipids, wherein the dispersant is selected from the group consisting of orange oil, pine oil, essential oil, terpenes, cationic ethoxylates, nonionic ethoxylates, propoxylates, anionic ethoxylates, and any combination thereof, and wherein the composition comprises about 80 to 90 percent transport component, 0.5 to 2 percent dispersant, 0.5 to 5 percent surface modifying agent and 5 to 20 percent of the one or more phospholipids and wherein the surface is located in a closed environment.

2. The method of claim 1 , wherein the composition is applied with a properly engineered spray bar or application device.

3. The method of claim 1 , wherein the composition is applied in an amount effective to control residual dust during the storage or transportation of the surface.

4. The method of claim 1 , wherein the surface is one item selected from the group consisting of a mined mineral, a synthesized dry material, coal, potash, phosphate, and road dust.

5. The method of claim 1 , wherein the transport component comprises a mixture of synthetic oils or a mixture of natural oils.

6. The method of claim 1 , wherein the composition comprises a curing control agent.
