This research is aimed at the preparation of biopolymeric skimmed milk powder (SMP) and pectin coated dual layer solid lipid nanoparticles loaded with soluble curcumin (CMN) to enhance the cytotoxicity of the drug delivered to the colon for colorectal cancer (CRC). The curcumin (C‐) and curcumin solid dispersion (C‐SD) (soluble curcumin) loaded solid lipid nanoparticle (SLN) (C‐SD‐SLN) are prepared by hot homogenization method and characterized its physicochemical properties. The surface of the C‐SD‐SLNs was coated with natural biopolymers of pectin and skimmed milk powder (SMP), called cetyl palmitate (CP)‐SD‐SLN. The resultant nanoparticles showed significantly high drug loading, better stability, and slower release profile (92.1%) in various GI conditions up to 72 H. zebra fish toxicity studies of CP‐SD‐SLN confirm its in vivo safety, and the result from in vitro cytotoxicity showed that 50% inhibition (26 μM/ml) is achieved with an amount of CP‐SD‐SLN, which was considerably lesser than free CMN. The result from flow cytometry analysis confirmed the cell cycle arrest in the G2/M phase (49.11%), and western blot analysis was performed to understand its molecular level apoptosis in Caco‐2 cells. The profound efficiency of SMP and pectin coated CP‐SD‐SLN is a promising preparation that indicated its potential application for CRC treatment without toxicity. Practical application The pharma and biotech industry is seeking techniques to increase potential and reduce the toxicity of chemotherapeutic agents. The solid lipid nanoparticle (SLN) has fascinated significant attention in anticancer drug delivery generally because of the targeted delivery to the particular site and devoid of other tissues. The present investigation provides the efficiency of skimmed milk powder (SMP)‐coated lipid shell contains soluble curcumin to release the drug at colon and improve the metabolism and therefore increase the potential activity several fold than native curcumin. The results show that SMP and pectin coated SLN is a potential carrier for delivery to the colon and thus improve anticancer potential of human adenocarcinoma (Caco‐2) cells of curcumin. These results will contribute in designing SLN techniques for optimizing the wide‐ranging quality of natural curcumin.
