Science
Mechanism of Action
As a highly volatile hydrocarbon, Isopentane acts primarily as a solvent and propellant within cosmetic formulations. It evaporates quickly, typically within 10 seconds when used as an aerosol, minimizing direct skin exposure. Its miscibility with fats and oils allows it to degrease the skin upon contact, a property that can contribute to dryness with prolonged interaction.

Stability
Optimal pH range for stability is not a primary concern; as a hydrocarbon, its stability is intrinsically linked to its volatility and flammability. It maintains stability under recommended storage conditions.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has consistently affirmed Isopentane's safety as a cosmetic ingredient, with reaffirmations in 2002 and 2023. This assessment considers its brief skin exposure during typical aerosol use, which mitigates potential dermal toxicity, sensitization, phototoxicity, and photosensitization risks. The FDA also approves Isopentane as an indirect food additive. While classified as a skin irritant by EU GHS for direct, prolonged contact, its rapid evaporation in cosmetic applications renders irritation and sensitization studies negative.
