These Probably the most steady NEs were identified to be those obtained with S2 and S7 (Figure 6). These NEsdepict equivalent mean size and ZP profiles for the duration of the assay. Large variations in size NEs depict equivalent imply size and ZP profiles for the duration of the assay. Substantial variations in size and ZP were recorded over time for the remaining surfactant-based NEs. The PI of NEs and ZP had been recorded more than time for the remaining surfactant-based NEs.

Osmolality translates the total concentration of solute within a solution, i.e., formulations using a low solute concentration have a low osmolality and formulations having a high concentration of solutes have a high osmolality value [36]. In the case of ocular delivery of drugs, formulations should not lead to any discomfort upon administration, thus tolerability from the formulations, pH and osmolality must be deemed. The cornea reacts upon modifications in pH and osmolality, which can provoke reflex blinking and tearing. The osmolality from the NEs made using the nine surfactants and CTAB was studied more than a period of 60 days, stored at four C. Table 5 shows the obtained outcomes. All of the formulations have a hypotonic profile as the osmolality was reduced than the physiologic values (about 289 mOsm/kg), which promotes fluid absorption. The use of hypotonic solutions is highly recommended in, f.
