Science
Mechanism of Action
Functions as a branched-chain aliphatic hydrocarbon that fills micro-gaps between corneocytes to instantly smooth texture. It creates a breathable, semi-occlusive barrier that limits transepidermal water loss (TEWL) before evaporating cleanly, leaving no greasy residue behind.

Key findings
- 01 A 2012 CIR Expert Panel review of 24 isoparaffin variations confirmed the ingredient is non-genotoxic and lacks reproductive toxicity, even at high concentrations.
- 02 Comparative irritation studies published in the Journal of Applied Toxicology indicate that C9-12 molecular chains are significantly more skin-compatible and less irritating than lower molecular weight hydrocarbon solvents.

Dusting Analysis
As a functional solvent and texture modifier rather than a primary active, it is rarely 'dusted' for marketing claims; its inclusion is typically driven by the structural requirements of the formulation's spreadability and dry-down time.
The Formula
Formulation
Stability
Highly chemically inert and stable against hydrolysis. Due to its high volatility, it requires airtight packaging to maintain formula integrity and prevent evaporation over time.
Synergies
- Lipophilic active ingredients
- Mineral UV filters
- Silicone elastomers
Conflicts
- Strong oxidizing agents
- Strong acids under high thermal conditions
