Science
Mechanism of Action
Carnauba Wax functions primarily as a natural thickening agent, contributing structural integrity and desirable consistency to formulations. On the skin, it forms a protective, water-repellent film, effectively reducing transepidermal water loss (TEWL) and thereby improving hydration and elasticity. Furthermore, it acts as a binding agent to enhance product hold and a dispersing agent, preventing aggregation of particulate ingredients for uniform distribution.
