  • Patent number: 7994095
    Abstract: Aqueous concentrates and aqueous compositions (e.g., agrochemical) containing a water-insoluble liquid antifoam agent (e.g., liquid silicone-containing antifoam agent) are disclosed. The water-insoluble liquid antifoam agent is incorporated into the concentrate or composition as a solution of the water-insoluble liquid antifoam agent solubilized in an organic solvent (e.g., isopropyl myristate, butyl cocoate or butyl laurate).
    Type: Grant

  • Publication number: 20050058574
    Abstract: The invention is an automated robotic system for the production and testing of formulations at a very high throughput. It is an integrated system of hardware and software capable of preparing and evaluating hundreds of emulsions per day. The system can formulate aqueous solutions (SL), oil in water emulsions (EW), suspo-emulsions (SE), micro capsule suspensions (CS), micro-emulsions (ME), and suspension concentrates (SC) at the 1 ml to 25 ml scale. The system can process emulsions rapidly in an automated way and enable very flexible formulation recipes to be introduced. The system allows chemists to generate experimental samples of varying recipe and method to be conducted in parallel with projected throughput of up to 1200 formulations processed and characterized per day. Materials and consumables can be distributed from storage storage systems to the work stations where dispensing of ingredients in various states can be performed, including solids, liquids, gels, pastes, suspensions and waxes.
