  • 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.

  • Patent number: 6653395
    Abstract: The present invention relates to new orthoester-based block polymers having a good antifoaming effect in liquid aqueous systems. The compounds are easily biologically degradable and, compared with traditional block polymers, have a comparatively high cloud point, which makes them readily compatible with other compounds and facilitates the formulation of homogeneous compositions. The new polymers are characterized in that they contain a block of at least 4 alkyleneoxy groups having 3 and/or 4 carbon atoms.
