Polyester chemistry is the same as studied by Carothers long ago, but polyester synthesis is still a very active field. New polymers have been very recently or will be soon commercially introduced PTT for fiber applications poly(ethylene naph-thalate) (PEN) for packaging and fiber applications and poly(lactic acid) (PLA), a biopolymer synthesized from renewable resources (corn syrup) introduced by Dow-Cargill for large-scale applications in textile industry and solid-state molding resins. Polyesters with unusual hyperbranched architecture also recently appeared and are claimed to find applications as crosstinkers, surfactants, or processing additives. 

Milk. Shake the sample vigorously, and immediately weigh 25 g of milk into a 500-mL round-bottom Aask. Add 10 drops of Dow Corning Antifoam B emulsion and 3 mL of 10% aqueous Igepal CO-660 (nonionic surfactant) to the Aask. Fortify the sample in the Aask.

The new cyclosporine formulation (Sandimmun Neoral, Novartis Pharmaceuticals Corporation, East Hanover, NJ) is a self-microemulsifying drug delivery system, which consists of the drug in a lipophilic solvent (corn oil), hydrophilic cosolvent (propylene glycol) surfactant and an antioxidant [37]. Upon contact with GI fluids, Sandimmun Neoral readily forms a homogenous, monophasic microemulsion, which allows the absorption of the drug molecules. Unlike Sandimmun, the formation of this microemulsion is independent of bile salt activity, and indeed, studies have shown that the absorption of cyclosporine from the new formulation is much less dependent on bile flow [38] and is unaffected by food intake [39],... 

Other methods, alternative methods of producing lump-free CWS starch have been described. One employs heat-moisture treatment of a mixture of granular starch, a surfactant containing a fatty acid moiety and (optionally) a gum.214 A process for making a corn starch product giving a uniform viscous dispersion when added to boiling water employs heating a mixture of starch, surfactant and water, followed by microwave radiation.215 Compositions that gel at low solids concentrations were prepared by complexation of starches of moderate (20-30%) amylose content with emulsifiers.216...

Herbicides applied at 1/64, 10, and 5 lb./ acre, respectively surfactant concentration was 0.005M in all cases. Toxicity index calculated by expressing fresh weight for each treatment as percentage of untreated control and subtracting this value from 100 (58)...

With both species, small quantities of other hexane-soluble, nonpolar metabolites were Isolated. Some were hydrolyzed In alkali and yielded the respective parent C-surfactants. These metabolites also had very low mobility in reversed-phase (RP) chromatography systems. This suggested they were equivalent to the surfactant fatty acid esters (Figure 1 Ri=fatty acyl, n=5 or 8) whose formation by cell-free homogenates from corn tissues was reported by Frear (11). 

Corn oil is used primarily in pharmaceutical formulations as a solvent for intramuscular injections or as a vehicle for topical preparations. Emulsions containing up to 67% corn oil are also used as oral nutritional supplements see also Section 18. When combined with surfactants and gel-forming polymers, it is used to formulate veterinary vaccines. 

A first approach to obtain silicon-containing surfactants without Si-0 bonds was made by Dow Corning [4, 5]. They reacted carbosilanes with several a-olefins containing reactive (e g., epoxy-fiinctional) moieties, catalyzed by platinum complexes. The surfactant properties and high stabilities of these compounds indicated a promising solution. However, the corresponding carbosilanes as precursors were synthesized via a Grignard reaction, so these silane surfactants were difficult and costly to produce. 

PU foams were prepared by the one-shot, free-rlse method. A homogeneous liquid mixture consisting of Nlax 31-28, Isonol-100, silicone surfactant DC-193 (Dow Corning), T-12, Nlax A-1 (Union Carbide), trlchlorofluoromethane (Freon llA, E.I. duPont de Nemours Co.), and water was mixed thoroughly with Isonate-143L. It was put Into a cold mold and allowed to free rise. 

The growth medium includes defined salts, complex nutrients, surfactants, and inducer. The salts are the typical fermentation salts, including potassium phosphate, ammonium nitrate, ammonium sulfate, calcium chloride, and magnesium sulfate [33]. The complex nutrients are most often 5 to 25 g L of corn steep liquor but can also include yeast extract. The surfactants are added to control or suppress foam formation. The surfactants used include commercial antifoams as well as soybean oil or palm oil. The inducers are proprietary to each manufacturer but will contain an inexpensive mixture of soluble and/or insoluble sugars. Some inducers used include milk whey, which contains lactose Solka floe cellulose or, sugar or paper mill waste streams.
