    • Liquid suspensions of particles in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed particles. The suspensions enable a user to rapidly add the suspension to water and to mix at low speeds without generating fugitive dust in the process. In addition, a liquid dispersion can provide an easy to use liquid containing higher concentrations of the active dispersed phase than can be accomplished by simply preparing an aqueous solution of the dispersed phase. Alternatively, highly water-soluble particles may also be suspended which have poor storage, freeze/thaw, or heat/cool stability. In some cases, liquid dispersions can yield controlled release of the dispersed phase because the dispersed phase is not in aqueous solution. The suspensions are environmentally safe and biodegradable and may be used in environmentally sensitive applications, such as for oil well treating fluids for offshore areas. The suspensions exhibit minimal oil or grease upon dilution and contain no surfactants that which can sometimes add to the oil and grease determination. The suspensions and the fluids produced by diluting the fluids to a working concentration of dispersed phase exhibit low toxicity to marine organisms and to humans. The suspension can be manufactured from ingredients suitable for use in personal care applications, such as cosmetics, shampoos and the like; from ingredients suitable for use in indirect contact with food; and from ingredients that are exempt from regulations as adjuvants for agricultural pesticides.
    • 颗粒在非水溶剂中的液体悬浮液在长时间内是非常稳定的,溶剂的分离最小并且没有分散颗粒的硬包装。 悬浮液使用户能够将悬浮液快速添加到水中并在低速下混合,而不会在该过程中产生逸散的灰尘。 此外,与通过简单地制备分散相的水溶液可以实现的,液体分散体可以提供含有较高浓度的活性分散相的易于使用的液体。 或者,也可以悬浮具有差的储存,冷冻/解冻或加热/冷却稳定性的高度水溶性颗粒。 在一些情况下,液体分散体可以产生分散相的受控释放,因为分散相不在水溶液中。 悬浮液是环境安全的和可生物降解的,并且可以用于环境敏感的应用中,例如用于近海地区的油井处理流体。 悬浮液在稀释时表现出最小的油或油脂,并且不含表面活性剂,这些表面活性剂有时可以增加油和油脂的测定。 通过将流体稀释至分散相的工作浓度而产生的悬浮液和流体对海洋生物和人类具有低毒性。 悬浮液可以由适用于个人护理应用的成分制成,例如化妆品,洗发剂等; 适用于与食品间接接触的成分; 以及作为农药辅助剂免除规定的成分。
