Science
Mechanism of Action
This ingredient functions by lowering the surface tension of cosmetic formulas, which significantly improves spreadability and 'glide' during application. It creates a breathable, microscopic film on the skin that prevents transepidermal water loss (TEWL) while acting as a volatile carrier that helps deliver heavier active ingredients into the stratum corneum before evaporating cleanly.

Key findings
- 01 A 16-week clinical evaluation utilized this alkane mixture as a delivery vehicle for MMP inhibitors in anti-aging research, confirming its high skin biocompatibility and efficient active ingredient transport.

Dusting Analysis
As a functional solvent and emollient, it is rarely 'dusted' for marketing purposes. It is typically included at functional levels (1-10%) to achieve specific textural goals; levels below 1% are generally insufficient to provide the desired slip or solvency.
The Formula
Formulation
Stability
Highly stable and chemically inert hydrocarbon; it remains effective regardless of pH and does not degrade in the presence of most cosmetic actives. It is flammable with a flashpoint between 40-60°C.
Synergies
- Sunscreen filters
- MMP inhibitors
- Silicone elastomers
Conflicts
- Strong oxidizing agents
- Strong acids
Safety
Safety Profile
Toxicologically comparable to C9-11 Isoparaffin. EU standards mandate benzene purity levels below 0.1% w/w. It is considered an aspiration hazard only in its raw, bulk industrial state, not in finished cosmetic dilutions.
