Science
Mechanism of Action
By integrating into the lipid matrix of the stratum corneum, it fills the gaps between skin cells (corneocytes) to create a smooth surface texture. It functions as a breathable occlusive, forming a hydrophobic micro-barrier that significantly limits transepidermal water loss (TEWL) to lock in moisture.

Clinical Evidence
High confidence10%
Key findings
- 01 Human patch testing on formulations up to 20% confirms a lack of sensitization and high skin compatibility.
- 02 Toxicological assessments indicate an LD50 greater than 5000 mg/kg, classifying the material as non-toxic and non-irritating.
Transparency
Dusting Analysis
As a functional emollient and solvent, C16-23 Alkane is rarely 'dusted' because it is used to achieve specific textural profiles; however, concentrations below 1% may not provide meaningful barrier support.
The Formula
Formulation
Stability
Exceptionally resilient to oxidation and thermal degradation due to its lack of reactive functional groups. It maintains structural integrity across a wide pH spectrum.
Synergies
- Silicones
- Vegetable oils
- Squalane
- Ceramides
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
Safety is contingent on high purification standards (PAH content below 3%). Not mutagenic or comedogenic.
