Binding of phenol red to cetylpyridinium chloride at air–solution and micelle–solution interfaces in aqueous ethylene glycol media

Physicochemical Studies on the Interaction between Sodium Dodecyl Sulfate and Methylene Blue in Methanol-Water Mixed Solvent Media

“…e interactions of surfactants with dyes play a crucial role in accomplishing a level of the color [5]. Although much research has been done on dye-surfactant interactions [6][7][8][9][10][11][12][13][14], studies in this area are still interesting and important for the theory and technology of dyeing [15].…”

Counterion Association of Ionic Drugs with Sodium Tetradecyl Sulfate in the Aqueous Medium

“…A comparable explanation was suggested for the breaks observed in CTAB (cetyltrimethylammonium bromide), TTAB, CPB (cetylpyridinium bromide), and CPC in a fixed concentration of Congo red aqueous solution . Our research group earlier showed that in the presence of 3.6 × 10 –5 mol L –1 PR, CPC exhibits two breakdowns in the surface tension experiment . Bhattarai investigated the micellization characteristics of cetyltrimethylammonium bromide in the presence of sodium polystyrenesulfonate in water at 298.15 K and discovered two breakdowns in the conductance studies.…”

“…Numerous drug–surfactant assemblies have been researched recently because of the vital significance of the pharmacological and therapeutic interactions between the drugs and the surfactant. − Combining a drug and a surfactant shows interaction and provides greater features than the drug or surfactant functioning independently. − Ionic medications have grown in importance recently as organic counterions or additions to enhance the interfacial and micellization properties of a charged surfactant and also to boost the concentration of pharmaceuticals that are only partially dissolved in the aqueous medium. , Whenever there are extra ingredients such as electrolytes, the critical micelle concentration (CMC) of the surfactants decreases. , Since they decrease their efficacy surface area per headgroup by limiting undesirable contact between each headgroup, additives, remarkably, make it simpler to induce an appearance change in surfactant micelles. The total amount of counterions that are physically associated with a micelle is compared to the amount of surfactant molecules (aggregate number) that reside in an ionic micelle to determine the counterion binding constant. − The most often used acceptable methods for estimating the counterion binding constant are the Corrin–Harkins (CH), modified CH approach, and the slope–ratio of conductance method …”

Influences of NaCl and Na2SO4 on the Micellization Behavior of the Mixture of Cetylpyridinium Chloride + Polyvinyl Pyrrolidone at Several Temperatures

“…Shunji Yunoki et al [ 9 ] studied that cetylpyridinium chloride (CPC) and polyvinyl alcohol (PVA) based antibacterial hydrogels showed excellent antibacterial properties where interaction between the used surfactant and polymer was significant. Dye-surfactant interaction for formulation in textile and various coloring industries deserves a remarkable role [ 10 ]. Recent research revealed that rinsing the oral captivity can restrain and counteract the menace of transmission of SARS-CoV-2 [ 11 , 12 ].…”
