Structure and Rheology on Nonionic Surfactant Solution for Skincare Cosmetics

Study of the Cloud Point of Nonionic Surfactant and Nonionic-cationic Surfactant Mixture: Effect of Electrolytes

Clouding phenomenon generally occurs with nonionic surfactants when the temperature of the system is raised to a certain value. This critical temperature is termed the cloud point (CP). The aqueous solutions of nonionic surfactants show complex phase behaviour including liquid-liquid phase separation at this temperature. The cloud point of aqueous surfactant solutions is influenced by the prese...

Rheology of Surfactant Solutions

Several surfactant molecules self-assemble in solution to form long, flexible wormlike micelles which get entangled with each other, leading to viscoelastic gel phases. We discuss our recent work on the rheology of such a gel formed in the dilute aqueous solutions of a surfactant CTAT. In the linear rheology regime, the storage modulus G(ω) and loss modulus G(ω) have been measured over a wide f...

Kinetics of nonionic surfactant adsorption at a fluid-fluid interface from a micellar solution.

Sphere-to-rod transitions of nonionic surfactant micelles in aqueous solution modeled by molecular dynamics simulations.

Control of the size and agglomeration of micellar systems is important for pharmaceutical applications such as drug delivery. Although shape-related transitions in surfactant solutions are studied experimentally, their molecular mechanisms are still not well understood. In this study, we use coarse-grained molecular dynamics simulations to describe micellar assemblies of pentaethylene glycol mo...

Skincare Bootcamp: The Evolving Role of Skincare

BACKGROUND Although cosmetic procedures have a significant impact on certain aspects of aging, such as deep, wrinkling, sagging, and volume loss, they fail to address the overall quality of the skin. METHODS Daily skincare routines potentially can have a significant long-term impact on the overall quality of a person's complexion. RESULTS By expanding our product knowledge, we can help our ...
