Advantages of microsponge based delivery systems

Sr. No.	Advantages	Ref.
1.	Shelf-life and product stability can be prolonged without using preservatives, since bacteria are too large to enter into the microsponge	[26]
2.	Highly compartmentalized nature of microsponges results in very high internal surface area hence, they exhibit high pay loading capacity	[27]
3.	Undesirable properties like oiliness and tackiness, or undesirable feel or odor of ingredients can be considerably reduced which makes them suitable for topical delivery to skin	[28]
4.	Liquids can be transformed into free flowing powder, providing material handling benefits	[28]
5.	Microsponges help in improving elegance of the formulation	[29]
6.	MDS augment the efficacy of topically active agents and enables their sustained release	[30]
7.	Microsponges consist of interconnecting voids within a non-collapsible structure, with large porous surface	[31]
8.	Stable over a wide pH range of 1–11 and up to a temperature of 130 °C	[32]
