Dispensing fluid formulation

Based on certain thermodynamic guidelines, a set of materials are selected. Based on the criteria defined in Fluid Requirements ink-jettable inks are formulated. An ink-jet printer or jetlab-II type printing system (see Figure 11-30) is employed to dispense an array of spots onto a substrate or into wells in different combinations of metal inks. The printed samples are individually or collectively processed so that all processing variables are explored. The sample properties are measured and archived along with composition data in a database. Finally, the database is mined to find optima and make connections between the composition of the catalysts, their structure and properties. 

As a preservative for industrial fluids, formaldehyde (formalin and paraformaldehyde) is preferably used in cosmetic products and in polymer dispersions (natural and synthetic latex) often in combination with other microbicides. Formaldehyde is listed in the EC list of preservatives allowed for the in-can protection of cosmetics (maximum authorized concentration 0.2%, except for products for oral hygiene 0.1%, prohibited in aerosol dispensers). Percentage of use in US cosmetic formulations 0.11% paraformaldehyde. Oil, fat and wax emulsions, starch and dextrine glues, adhesive dispersions, pigment and filler slurries, thickening solutions and other aqueous formulations containing no proteins can be preserved by the addition of formaldehyde, too in order to...
