Science
Mechanism of Action
This ingredient operates as a multi-functional lipid carrier and skin conditioner. By forming a breathable, non-greasy film over the stratum corneum, it effectively inhibits transepidermal water loss (TEWL) while serving as a stable delivery vehicle that enhances the penetration of lipophilic active ingredients.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 At a 3% concentration within Nanostructured Lipid Carriers (NLCs), it significantly improves the stability and skin-penetration depth of encapsulated actives while boosting hydration levels.
- 02 Clinical patch testing on subjects with compromised and eczematous skin confirmed zero irritation potential even at concentrations up to 100%.
Transparency
Dusting Analysis
Because it acts as both a texture enhancer and a carrier, it is rarely 'dusted'; however, for functional barrier repair and delivery system stabilization, concentrations of 3% or higher are clinically preferred.
The Formula
Formulation
Stability
Highly resistant to oxidation due to its saturated fatty acid chain structure. It maintains integrity across a melting range of 30-44°C, making it an excellent stabilizer for emulsions exposed to fluctuating temperatures.
Synergies
- Lipophilic vitamins
- Ceramides
- Nanostructured Lipid Carriers (NLC)
Conflicts
- Strong oxidizing agents
- Highly alkaline bases (potential saponification)
Safety
Safety Profile
Recognized as GRAS (Generally Recognized as Safe) by the FDA. The CIR Expert Panel confirms its safety in leave-on products at concentrations nearly reaching 96%.
