Answer 26

Emulsifier

Question 27

Stearyl alcohol

Answer 27

Emulsifier, thicken oil phase

Question 28

What is the difference between dispersion and flocculation?

Answer 28

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

Question 29

Newtonian flow

Answer 29

Water flows in proportion to force. Linear slope.

Question 30

Plastic

Answer 30

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

Question 31

Pseudoplastic

Answer 31

Takes more force than plastic to flow, eventually catches up

Question 32

Dilatant

Answer 32

High solids content. Becomes thicker with stress shear thickening

Question 33

3 types of non Newtonian flow

Answer 33

Plastic Pseudo plastic Dilatant

Question 34

Thixotropy

Answer 34

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.

Question 35

Wetting

Answer 35

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

Question 36

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

Answer 36

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