emulsifying agent
Cellulose acetate butyrate-poly(vinyl pyrrolidone) (CAB-PVP) blend microspheres were prepared using the solvent evaporation technique using poly(vinyl alcohol) as an emulsifying agent.
      
The best reaction conditions were an acid medium, Triton X-100 as the emulsifying agent and a temperature of 30°C.
      
The hydrocarbon-degrading strain Acinetobacter calcoaceticus RAG-1 produces an extracellular emulsifying agent capable of forming stable oil-in-water emulsions.
      
Production of emulsifying agent during growth of Pseudomonas cepacia with 2,4,5-trichlorophenoxyacetic acid
      
The emulsifying agent was produced in response to growth on 2,4,5-T, although some emulsification was observed in culture supernatant of glucose grown cells.
      
The emulsifying agent is most active with 2,4,5-T but has some activity towards other chlorinated compounds such as chlorophenols.
      
In growing culture the emulsifying agent adheres to the cell surface as a slimy layer.
      
The emulsifying agent is believed to have a role in transport of 2,4,5-T into the cells.
      
In all cases Mg(NO3)2 was used as chemical modifier and Triton X-100 (0.2% w/v) as emulsifying agent.
      
Sodium pentanesulfonate was chosen as the most suitable surfactant to be used as emulsifying agent, whereas ethyl acetate was selected as the organic solvent to form the emulsions.
      
TG22, was isolated and selected for its production of an extracellular emulsifying agent, AE22.
      
Steroids were not detected in any of the cases.3.Preliminary experiments with a snail (Helix pomatia L.) point to another type of emulsifying agent, a sulfate group with fatty acids and a third substance, probably a long chain alcohol.
      
It was found that the percentage of 0.5 and 0.25 of the emulsifying agent with a ratio of oil to water as 20∶80, best stable emulsions are produced.
      
The influence of emulsifying agent concentration on emulsion viscosity
      
The viscosity of emulsions is affected by the concentration of emulsifying agent normally employed in their preparation.
      
Bordeaux mixture when used as stabilizer exhibits the tendency of emulsifying agent antagonism and formation of multiple emulsion.
      
The perplexing fact about these emulsions is that emulsifying agent antagonism is set up with certain solid agents while with other similar compounds it is evaded.
      
If a hydrocolloid or protein is used as an emulsifying agent an interfacial film is formed at the oil-water interface and this may be liquid or viscoelastic solid in properties.
      
The major advantage of this experimental approach is that it simplifies and shortens the assay procedure, since it eliminates the necessity to initially prepare [14C]phytoene and then add it to the incubation with an emulsifying agent.
