Effect of Lipid Composition on In Vitro Release and Skin Deposition of Curcumin Encapsulated Liposomes

Table 3

Diameter, polydispersity index, and zeta-potential of different types of curcumin encapsulated liposomes. Each value represents mean ± SD (). Statistically different values are followed by different superscripts and vice versa, in each column.

Liposomal formulation	Diameter (nm)	Polydispersity index	Zeta-potential (mV)
NL	284.2 ± 6.3	0.296 ± 0.046	−57.4 ± 3.5
NHL	225.7 ± 5.0	0.293 ± 0.020	−48.7 ± 1.7
PL	226.8 ± 10.9	0.399 ± 0.038	+42.0 ± 0.3
PHL	265.3 ± 3.3	0.363 ± 0.059	+48.2 ± 0.8

NL: negatively charged liposomes; NHL: negatively charged hybrid liposomes.
PL: positively charged liposomes; PHL: positively charged hybrid liposomes.
