Q1Domain Verified
In the context of emulsification, which of the following scenarios, as likely explored in "The Complete Cosmetic Chemistry Course 2026," would present the most significant challenge to achieving a stable O/W emulsion with a high internal phase volume?
Incorporating a high HLB surfactant with a high oil phase viscosity and a high internal phase volume, necessitating a robust interfacial film.
Employing a high HLB surfactant with a low water phase viscosity and a high concentration of emulsifier.
Using a low HLB surfactant with a low oil phase viscosity and a low internal phase volume, relying on steric stabilization.
Utilizing a low HLB surfactant with a high oil phase viscosity.
Q2Domain Verified
Considering principles likely covered in "The Complete Cosmetic Chemistry Course 2026," what is the primary consequence of exceeding the critical micelle concentration (CMC) of a non-ionic surfactant in a cosmetic formulation, beyond simple micelle formation?
A decrease in interfacial tension to near zero, causing spontaneous emulsification and potential phase inversion.
A rapid increase in zeta potential, leading to electrostatic repulsion between dispersed particles.
Increased solubility of highly lipophilic active ingredients due to enhanced micellar solubilization.
A significant decrease in the formulation's viscosity due to micelle packing disruption.
Q3Domain Verified
A formulator using a novel polymeric emulsifier, as might be discussed in "The Complete Cosmetic Chemistry Course 2026," observes a formulation exhibiting significant creaming but no signs of coalescence or phase separation after prolonged storage. What is the most probable explanation for this phenomenon?
The polymeric emulsifier is acting as a flocculating agent, causing droplets to clump together.
The polymeric emulsifier has failed to form a stable interfacial film, allowing for rapid droplet aggregation.
The formulation's viscosity is too low, leading to rapid creaming due to density differences.
The polymeric emulsifier is effectively providing steric stabilization, preventing droplet coalescence but not sedimentation.
