[CLASSES OF SUSPENSION]

TRUE OR FALSE:

Lotions have LOWER viscosity than creams and gels.

Gels

These are semisolid systems consisting of either suspensions made up of SMALL INORGANIC particles or LARGE ORGANIC molecules enclosed and interpenetrated by a liquid.

Imbibition

[TERMINOLOGIES RELATED TO GELS]

Absorption of liquid WITHOUT measurable increase in volume.

Swelling

[TERMINOLOGIES RELATED TO GELS]

Absorption of liquid WITH measurable increase in volume.

Syneresis

[TERMINOLOGIES RELATED TO GELS]

The dispersion medium is SQUEEZED OUT in droplets upon standing, and the gel SHRINKS.

Thixotropy

[TERMINOLOGIES RELATED TO GELS]

REVERSIBLE gel-sol formation with NO CHANGE in volume or temperature.

Xerogel

[TERMINOLOGIES RELATED TO GELS]

Gel that has SHURNK and only the solid FRAMEWORK remains.

● By Chemical Reaction

● By Simple Hydration

[GELS]

Preparation of gels

● Aluminum Hydroxide Gel, USP

[EXAMPLES OF GELS]

These gels are used as ANTACIDS.

Sodium Fluoride and Orthophosphoric Acid Gels

[EXAMPLES OF GELS]

This gel is applied to teeth as DENTAL PROPHYLACTIC.

Aluminum Hydroxide Gel, USP

[GELS]

This gel can prepared by BOTH chemical reaction and simple hydration.

Magmas and Milks

These are aqueous suspensions of insoluble INORGANIC drugs and differ from gels mainly that the suspended particles are LARGER.
