Science
Mechanism of Action
On the skin, Pentaerythrityl Distearate creates a subtle, protective film that minimizes transepidermal water loss, leading to enhanced hydration and a perceptibly softer skin texture. Within a formulation, it acts as a robust emulsifier, enabling the stable combination of oil and water phases to prevent separation. It also functions as a stabilizer and thickener, improving the product's viscosity, spreadability, and overall sensorial experience by imparting a smooth, non-waxy finish. Furthermore, it aids in retaining moisture within the product itself, contributing a humectant effect.
