Science
Mechanism of Action
It functions as an occlusive emollient, forming a water-resistant lipid film to prevent transepidermal water loss (TEWL) and trap existing moisture. Acetylation removes polar hydroxyl groups, rendering it more hydrophobic, which enhances skin 'slip' and stability.

The Formula
Formulation
Stability
Highly stable due to its non-drying, saturated hydrocarbon nature, resisting autoxidation and rancidity. It has a melting point of approximately 38-44°C.
Conflicts
- Strong oxidizing agents
- May destabilize certain O/W emulsions due to high hydrophobicity
Safety
Safety Profile
The CIR re-affirmed its safety in 2024, with current leave-on product usage up to 6.3%. It may elicit reactions in 1.8-3% of eczema patients with wool alcohol allergies.
