What Is Dodecane?

Dodecane is a straight-chain alkane hydrocarbon derived from petroleum. It is a colourless, volatile liquid that functions as a solvent and carrier in cosmetic formulations.

In skincare products, dodecane is used mainly as a vehicle for fragrance compounds, helping to dissolve and distribute scent throughout a product. It appears in approximately 0.2% of skincare formulations, typically at low concentrations.

How It Works

Dodecane functions as a non-polar solvent, meaning it dissolves and distributes non-water-soluble substances, including many fragrance molecules. Once applied to skin, its volatile nature means it evaporates relatively quickly.

Because it is a hydrocarbon, it does not form chemical bonds with skin components; instead, it acts as a carrier medium that delivers other actives or fragrances and then disperses.

Clinical Evidence & References

Research on dodecane's dermal effects is limited in the context of cosmetic use. Animal studies examining prolonged or high-level occupational exposure (relevant to industrial settings rather than skincare application) have shown variable irritation responses depending on exposure duration and concentration.

At the low concentrations typical in skincare products, dodecane is not expected to pose significant concerns for most users. However, evidence specifically evaluating its safety in cosmetic formulations at these concentrations is sparse, so individual sensitivity remains possible.

How to Use

Dodecane-containing products can be used as directed on the label. Because it is volatile, products containing it should be stored with lids firmly closed to prevent ingredient loss over time. If fragrance sensitivity is a concern, patch-test before full application.

Safety & Precautions

Dodecane is generally well-tolerated at the concentrations used in skincare. Those with fragrance sensitivity or volatile compound sensitivity may wish to avoid products containing it.
