Science
Mechanism of Action
This ingredient operates as a surfactant, effectively lowering the surface tension between different phases within a formulation, which is critical for creating stable emulsions. As an emulsifier, it prevents the separation of oil and water components. Additionally, it acts as a viscosity enhancer to achieve desired product consistency and can serve as a mild cleansing agent.
