Science
Mechanism of Action
This ingredient functions as a superior occlusive emollient. Due to its high molecular weight and branched-chain architecture, it forms a hydrophobic film on the skin's surface, effectively locking in moisture and preventing transepidermal water loss (TEWL) without penetrating the deeper layers of the stratum corneum.

Key findings
- 01 Human patch testing conducted on 100% undiluted mixtures (C18-70 range) confirmed the substance is non-irritating and non-sensitizing over 48-hour exposure periods.
- 02 Safety evaluations published in the International Journal of Toxicology support its use as a systemic-safe solvent and emollient, citing its bulky molecular size as a deterrent to significant skin absorption.
Transparency
Dusting Analysis
Because it is often used as a functional solvent or texture enhancer, concentrations below 1% in moisturizers may be insufficient to provide meaningful occlusive benefits, though it is rarely used in 'marketing-only' amounts.
The Formula
Formulation
Stability
Extremely chemically inert and resistant to photo-oxidation, temperature fluctuations, and discoloration. It maintains stability across a wide environmental range and does not impact formula pH.
Synergies
- Humectants (to seal in moisture)
- Lipophilic active ingredients
Conflicts
- Water-based systems (requires emulsification)
- Highly polar solvents
Safety
