The rate of sedimentation is generally high in _____.

An emulsion consists of _________.

The purpose of an emulsifier is to __________.

_____ is a procedure when oil is triturated with the gum before adding in water for preparing a primary emulsion.

Which of the following is NOT used as an emulsifying agent?

In Conductivity Test, if bulb glows on passing electric current, this means that the emulsion is ________.

Which of the following is NOT a method to identify the type of emulsion?

In precipitation method of preparing suspensions, particle size control is important. For suspensions intended for parenteral and inhalation us, the ideal particle size range is _______.

This equipment produces finely divided particles by spraying a mist of liquid through a heated chamber, drying immediately and collecting the dried powders in a clean receptacle;

A suspension that appears as masses of gels, consisting of floccules of small distinct particles;

A method of particle size reduction in suspensions, wherein the particles are subjected in a turbulent air chamber, thus colliding with each other to fracture and produce particles with sizes 5 microns and below;

It is the reverse of creaming; wherein less concentrated emulsified droplets separate from the internal phase. It usually settles at the bottom of the external phase of the container;

The more preferred type of suspension is the flocculated one due to:

The particles of the dispersed phase vary widely in size, from large particles visible to the naked eye down to the particles of colloidal dimensions, falling between 1.0nm and 0.5 um in size.

If the oleaginous phase is the internal phase, then the emulsion is referred to as:

This theory of emulsification assumes monomolecular layers of emulsifying agent curved around a droplet of the internal phase of the emulsion.

This theory places the emulsifying agent at the interface between the oil and water, surrounding the droplets of the internal phase as thin layer of film adsorbed on the surface of drops

It provides good emulsion stabilization in a concentration of 0.5 to 1%.

These are thermodynamically stable, optically transparent, isotropic mixtures of a biphasic oil-water system stabilized with surfactant.

It is the taking up of a certain amount of liquid without a measurable increase in size.

It is the result of the interaction of relativity weak particles, which may have sufficient emulsifier coverage and therefore prevent coalescence.

The following emulsions are used orally, except:

If the emulsifying agent is lipophilic, then ________ will be the continuous phase, and w/o type emulsion will be formed.

It can produce extremely fine droplets depending on the viscosity and internal tension of the system.

This is an equipment for emulsions which produce extremely fine particles for moderately viscous emulsions

This method is specifically used for the extemporaneous preparation of emulsions from volatile oils or oleaginous substances of low viscosities

Non-ionic emulsifying agents, except:

Wetting agents have an assigned HLB value of ______.

In Dye Solubility test, if the dispersed globules appear red and the ‘ground’ colourless, the emulsion is most likely what type?
