Science
Mechanism of Action
Operating as a non-polar solvent, Heptane effectively dissolves a broad spectrum of organic compounds, including natural skin lipids. This potent solvent action enables it to penetrate the epidermal barrier, leading to a detrimental defatting effect that compromises the skin's natural moisture and protective functions.

Dusting Analysis
Heptane is classified as a skin irritant (Category 2, H315) and an aspiration hazard (Category 1, H304). Its capacity to severely defat the skin, leading to dryness, cracking, and inflammation, warrants significant concern and indicates it is unsuitable for skin contact in cosmetic formulations.
The Formula
Formulation
Stability
Heptane is a highly flammable liquid that evaporates rapidly, leaving minimal residue. In protein-containing formulations, it may exacerbate oxidative conditions, potentially contributing to protein degradation.
Conflicts
- Strong oxidizing agents
- Heat, sparks, open flames, and other ignition sources
Safety
Safety Profile
Classified by OSHA as a hazardous substance, n-heptane exposure can induce short-term effects such as irritation of the eyes, nose, or throat, alongside headaches, dizziness, or loss of consciousness. Prolonged skin contact demonstrably defats the skin, resulting in dryness, cracking, inflammation, and irritation. It is explicitly categorized as a skin irritant and an aspiration hazard.
