Describe spreading test for identification of emulsions.
Describe viscosity test for identification of emulsions.
o/w emulsions will have higher viscosity value than w/o emulsion.
o/w emulsions will have _____ (higher/lower) viscosity value than w/o emulsion.
Distinguish between o/w and w/o emulsions using viscosity test.
o/w emulsions will have lower viscosity value than w/o emulsion.
List the tests used for the detection of types of emulsions.
Dilution test for the identification of emulsion, if on adding water the emulsion character is retained then the emulsion is identified as _____ (oil in water / water in oil) type.
Describe the Dilution test for the identification of emulsion.
Dilution test for the identification of emulsion, if on adding oil if the emulsion character is retained then the emulsion is identified as _____ (oil in water/water in oil) type.
Dilution test for the identification of emulsion, if on adding water the emulsion character is retained then the emulsion is identified as w/o type.
