Science
Mechanism of Action
Isopulegol primarily functions as a sensory agent, directly stimulating receptors at nerve endings within the skin to induce a pronounced cooling effect. While acting as a natural precursor to menthol, it also demonstrates potential anti-inflammatory and antimicrobial capabilities. A related derivative, isopulegol decanoate, has been observed to temporarily enhance skin permeation by influencing the diffusion of intercellular lipids in the stratum corneum, with the skin barrier integrity subsequently recovering.

Isopulegol is generally stable under typical conditions and at a neutral pH, making it robust for various applications.
Safety
Safety Profile
The Research Institute for Fragrance Materials (RIFM) has concluded Isopulegol is safe for use in everyday products, indicating no genotoxicity or skin sensitization potential. While recommended up to 6.0% in fragrance concentrates, the maximum skin level in finished fine fragrance products is 0.05%. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the FDA have also deemed it safe as a flavoring agent or adjuvant.
