The physicochemical properties of the cross-linked PA layer are the main criteria determining the filtration performance of the resultant TFC membrane, and this selective layer can be created through Interfacial Polymerization (IP) between two immiscible active monomers, i.e., amine monomer in aqueous solution and acyl chloride monomer in organic solution. This patent review article intends to provide insights to researchers in fabricating improved properties of TFC membranes through the utilization of secondary monomers during IP process. To the best of our knowledge, this is the first review that gives a state-of-the-art account of the subject matter by emphasizing the impacts of secondary monomers (both amine and acyl chloride monomers) on the properties of conventional TFC membranes for nanofiltration and reverse osmosis applications. Our review indicated that the introduction of secondary monomers into either aqueous or organic solution could alter the physical and chemical properties of PA layer, which led to variations in membrane filtration performance. Nevertheless, more research is still required, as most of the secondary monomers reported in the literature did not overcome the membrane trade-off effect between permeability and selectivity.

In such cases, S-SMEEDS are the best carriers used universally for the delivery of hydrophobic drugs. SEDDS are also used but due to their limitations, SSMEDDS are used widely. These are the isotropic mixtures of oils, co-solvents, and surfactants. SSMEDDS are physically stable, easy to manufacture, easy to fill in gelatin capsules as well as improve the drug bioavailability by releasing the drug in the emulsion form into the gastrointestinal tract and enable smooth absorption of the drug through the intestinal lymphatic pathway.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;We conducted a literature search related to our review, also employing the peer-reviewed research, and provided a conceptual framework. Standard tools were used for drawing the figures of the paper, and various search engines were used for literature exploration. In this review article, the author has discussed the importance of S-SMEDDS, selection criteria for excipients, pseudo-ternary diagram, mechanism of action of S-SMEDDS, solidification techniques used for S-SMEDDS, Characterization of SEDDS and S-SMEDDS including Stability Evaluation of both and future prospects have been concluded through recent findings on S-SMEDDS in Cancer as well as a neoteric patent on S-SMEDDS.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Many research papers have been discussed in this review article, from which it was found that the ternary phase diagram is the most crucial part for developing the SMEDDS. From the various research findings, it was found that the excipient selection is the essential step which decides the strong therapeutic effect of the formulation. The significant outcome related to solid-SMEDDS is the less the globule size, the higher would be the bioavailability. The method in which adsorption of a solid carrier takes place is most widely used for the preparation of solid-SMEDDS. After reviewing many patents, it was observed that the solid-SMEDDS have a strong potential for targeting and treating different types of cancer due to their properties to enhance permeation and increase bioavailability.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;S-SMEEDS are more acceptable pharmaceutically as compared to SEDDS due to their various advantages over SEDDS, such as stability issue is prevalent with SEDDS.
