Dried barium lanolate is an anti-rust additive, pigment dispersant and anti-caking agent for paints and coatings. It is also an intermediate used to make purified fatty acids of lanolin for conversion into emulsifiers, emollients and dispersants in cosmetics and pharmaceuticals. Before drying, barium lanolate filter cake contains a low boiling point, flammable~ solvent. Above a certain temperature, it decomposes into fatty acid components. It also forms a sticky, resinous mass when subjected to severe mechanical action. Even after drying, the product, if too hot, is tacky, prone to compact, with the potential of spontaneous combustion. The previous drying method was simply storage in open containers, but quality control was difficult. Compaction during storage produced agglomerated lumps.
