The aliphatic solvents, including mineral spirits, odorless kerosene and mineral seal oil, are predominantly sold to chemical distributors in Los Angeles, Salt Lake City, San Francisco and Seattle. Mineral spirits are used as paint thinners, cleaning fluids, coatings additives and perfume carriers. Odorless kerosene is used as a transportation fuel in low temperature or mountain areas, home heating fuel, insecticide base, a leaching agent in base metal mining operations, a carrier in ink formulations and as a coatings carrier. Mineral seal oil is used in formulations of metal rolling lubricants, as defoaming agents in the paper industry and as carriers and diluents in specialty chemical formulations. Aliphatic solvents have limited end user markets which are not easily penetrated.
