Science
Mechanism of Action
This ingredient functions by creating a breathable, water-repellent occlusive barrier that effectively locks in moisture and prevents trans-epidermal water loss (TEWL). Due to its low viscosity, it serves as a lubricant and penetration enhancer, improving the 'slip' of products and assisting deeper delivery of co-formulated actives.
Research
Clinical Evidence
High confidence6%
Key findings
- 01 Demonstrated efficacy in restoring skin capacitance and softness while reducing TEWL in subjects with compromised barriers, such as those with xerosis or atopic dermatitis.
- 02 Validated as the maximum safe threshold for leave-on application, showing negligible irritation potential and zero sensitization in human clinical patch testing.

Dusting Analysis
With clinical benefits observed at concentrations as low as 0.5%, it is rarely 'dusted.' However, its secondary role as a texture enhancer means it is often used at 1-3% even when not the primary active.
The Formula
Formulation
Stability
Thermally stable and resistant to electrolytes. It should be incorporated into the oil phase (melting point 21-23°C). Extremely stable in acidic environments but may undergo slow hydrolysis in highly alkaline conditions.
Synergies
- Lipophilic actives
- Mineral oils
- Vegetable triglycerides
Conflicts
- Strong oxidizing agents
- Strongly alkaline solutions (pH > 9.0)
Safety
Safety Profile
Recognized as GRAS (Generally Recognized as Safe) by the FDA for food use, further reinforcing its safety profile for topical application.

Verdict
An excellent textural modifier and barrier-support agent for dry or sensitive skin, though its high comedogenicity makes it less ideal for acne-prone individuals.
