The effectiveness of octadecanoic acid changed superimposed double hydroxides (OLDH) as viscousness modifier and stabilizer in mineral jelly (PJ) formulations has been studied and its rheologic properties evaluated. Mg-Al-LDH was organically changed exploitation octadecanoic acid that is anionic surface-active agent wide employed in topical formulations. successful incorporation of stearate ion into LDH interlayers was confirmed by XRD, FTIR, SEM, and TGA results. PJ formulations were ready exploitation completely different OLDH contents (0.5, 1, 1.5 and 2 wt. %) employing a high shear mixer. The incorporation of OLDH considerably exaggerated the viscousness of the PJ formulations that is explained by color force between OLDH particles and organic compound chains of PJ. The percolation threshold was discovered to be at one.5 wt.% of OLDH loading suggesting the presence of a well-developed interface between the filler and therefore the compound matrix. The non-Newtonian shear dilution indicated the formation of gel-like structure. Dynamic state rheologic information of PJ formulations showed a dominance of elastic property imparted by solid introduce OLDH based mostly system. OLDH, therefore, showed nice promise as associate economical structural ingredient in cosmetic formulations providing viscousness improvement furthermore as shear dilution behaviour that may end in formulation stability, higher skin feel and spreadability.
