Abstract This work characterized the macroscopic thermodynamic properties of ionic micellar solutions. Formulation‐composition studies were done along one dimension by varying salinity (S) or oil–water ratio (WOR) in mixtures sodium dodecyl sulfate, water, n ‐heptane, and 1‐pentanol at 25°C 1 atm. Material balance multiple regression models used to get partial, mixed, excess molar volumes. The UNIFAC local composition model, coupled with Debye–Hückel theory, was employed calculate activity coefficients dimensionless Gibbs energies (partial, excess). equilibrium SOW systems exhibited phase transitions (WI‐WIII‐WII), solubilization increasing as increased constant WOR. Solubilization peaked optimal formulation, further increases WOR enhanced up formation a single‐phase system.

Statistical simplex centroid experimental design and formulation maps to predict the stability in cosmetic emulsions containing commercial emulsifiers

Journal of Surfactants and Detergents, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

Abstract Formulating cosmetic products to meet consumer expectations poses significant challenges in terms of stability and shelf life. This work evaluates emulsions formulated with three commercial emulsifiers: Polyglyceryl‐3 distearate (Dermofeel®, a biobased surfactant), Glyceryl stearate (50%)/PEG‐100 (50%) (Lipomulse®, nonionic mixture glyceryl ethoxylated surfactants), Potassium cetyl phosphate (Amphisol K®, an anionic surfactant). Additionally, emollients, namely Caprylic/Capric Triglyceride, Isoamyl Cocoate, Jojoba Oil, were incorporated into the formulations. The effect emulsion composition on stability, droplet size, rheology, texture was systematically assessed via experiments multivariate regression modeling, thereby providing objective tool for formulation. lifetime showed that containing exhibited separation velocities larger than 60 μm/s, whereas those other emulsifiers below 40 indicating lifetimes. A predictive model based statistical simplex centroid experimental design developed evaluate velocity system, enabling assessment important variables influence stability. results indicate (such as oil concentration) formulation surfactant nature type) are determining but also secondary effects such surfactant‐emollient interactions crucial predict emulsions.
