Science
Mechanism of Action
On the skin, 2-Ethylhexanol functions principally as a solvent, demonstrating limited water solubility but readily dissolving in most organic solvents. This solvent activity can lead to a defatting effect on the skin's surface, potentially disrupting the natural lipid barrier and contributing to dryness or cracking. Additionally, it can act as a dispersing and wetting agent.

Stability
This ingredient is characterized as a clear, mobile, and neutral liquid. It exhibits vigorous to violent reactivity with strong oxidizers and strong bases. Decomposition occurs upon heating or burning, leading to the emission of acrid smoke and fumes.

Safety
Safety Profile
2-Ethylhexanol is classified as a skin and eye irritant. It presents with low acute toxicity via oral and dermal routes but is considered moderately irritating to the skin and severely irritating to the eyes. Importantly, it is non-sensitizing, meaning it does not typically cause allergic skin reactions. The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed 2-Ethylhexanol itself; however, it has deemed its esters (alkyl ethylhexanoates) safe in cosmetic formulations at high concentrations (up to 77.3% in rinse-off and 52% in leave-on products) provided they are formulated to be nonirritating. The EPA has determined 2-Ethylhexanol is not carcinogenic, and the FDA lists it as a flavoring agent/adjuvant and a food contact substance.

Verdict
Due to its inherent moderate irritancy and potential defatting effects on the skin, 2-Ethylhexanol is not recommended for direct inclusion in topical skincare formulations.
