emulsion
1.these are biphasic liquids preparations containing two immiscible liquids one of which is disperesd as a minute globules into the other .
2. globule size of the dispersed liquid is in the rang of 0.5 to 0.25 microns .
3.emulsifying agent is required to make a stable emuision.
4.emulsions are of two type oil -in-water type and water-in -oil type.
5. during storage freezing should be avoided as it may lead to cracking.
suspensions
1. these are biphasic liquid dosage form of medicament in which finely divided solid particles are dispersed in a liquid.
2. particle size of suspended solid is in the range of 0.5 to 5microns.
3.suspending gent is required to make a stable suspension .
4. suspensions are of two types flocculated and deflocculated.
5.during storage freezing should be avoided as it leads to aggregation.
