27
Q

Stearyl alcohol

A

Emulsifier, thicken oil phase

28
Q

What is the difference between dispersion and flocculation?

A

Floculants settle fast but less prone to compaction and break up easily.
Dispersion settles as a cake, irreversible, difficult to break up.

29
Q

Newtonian flow

A

Water flows in proportion to force. Linear slope.

30
Q

Plastic

A

Liquid does not flow proportional to force initially then catches up ( ketchup) shear thinning

31
Q

Pseudoplastic

A

Takes more force than plastic to flow, eventually catches up

32
Q

Dilatant

A

High solids content. Becomes thicker with stress shear thickening

33
Q

3 types of non Newtonian flow

A

Plastic
Pseudo plastic
Dilatant

34
Q

Thixotropy

A

Ability of a system that was disturbed by shear stress to return to it’s undisturbed structure. Keeps particles from sinking too quickly but need plastic or pseudo plastic properties for good flow.

35
Q

Wetting

A

A surface active agent added to reduce the surface tension Water enters the pore and displaces the air. Same as surfactant in emulsions.

36
Q

What are the 3 steps in order to prepare a suspension?

A

Reduce particle size
Wetting
Addition of dispersion medium and uniformity is established.
