Science
Mechanism of Action
As a lightweight emollient, Triheptanoin forms a subtle barrier on the skin's surface, preventing transepidermal water loss and thus maintaining optimal hydration. This action contributes to a smoother, softer skin texture. Additionally, its solvent properties allow it to improve the dispersion of active ingredients like UV filters and pigments within formulations, ensuring even application.

Stability
Triheptanoin demonstrates robust chemical and physical stability, maintaining integrity when integrated into various matrices. Stability tests, primarily conducted for oral medical formulations, show it remains stable in food and beverages for hours at ambient to warm temperatures (25–40 °C) and for up to 48 hours refrigerated (2–8 °C). It even withstands high temperatures, such as baking at 200 °C for seven days, suggesting excellent general stability for cosmetic applications.
Conflicts
- Polystyrene plastic (specific to medical administration, potential for material degradation)
- PVC plastic (specific to medical administration, potential for material degradation)
- Not to be added to feeding bags (specific to medical administration, likely due to formulation or material interaction concerns)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded Triheptanoin is safe for use in cosmetics under current practices and concentrations, typically ranging from 1–20%. It is globally recognized for its low likelihood of skin irritation and non-toxic profile for topical applications. Notably, a pharmaceutical form (Dojolvi) received US FDA approval in 2020 for oral use in specific metabolic disorders, further underscoring its safety profile, albeit in a different context. Its use in European cosmetics is generally accepted if derived from plant sources.
