Science
Mechanism of Action
This ingredient operates as an occlusive film-former, creating a breathable yet robust physical shield on the stratum corneum. By leveraging long carbon chains (C18-C36), it effectively traps moisture within the skin layers to minimize transepidermal water loss (TEWL) and stabilizes the structural integrity of emulsions and stick-based products.

Dusting Analysis
As a functional texture enhancer and gellant, this ingredient is rarely 'dusted' for marketing claims; it is typically used at functional levels required to achieve specific product viscosity or barrier performance.
The Formula
Formulation
Stability
A highly stable, non-ionic synthetic wax with a melting point between 70-75°C. It is resistant to oxidation but requires precise temperature management and high-shear mixing during the cooling phase to prevent unwanted crystallization.
