Science
Mechanism of Action
This synthetic ester acts as a lightweight emollient and skin-conditioning agent. It works by rapidly absorbing into the skin, forming a subtle protective barrier that effectively minimizes moisture loss. This action results in enhanced skin smoothness, improved hydration, and a non-greasy feel, while also boosting product spreadability and overall sensory appeal.

The Formula
Formulation
Stability
This ingredient is stable within a pH range of 3-10, with optimal stability observed between pH 3 and 9. It demonstrates good oxidative stability, though incorporating antioxidants like tocopherols is advised for formulas susceptible to rancidity. While heat-tolerant, temperatures above 80°C should be avoided, and incorporation during the cool-down phase is recommended to maintain sensory qualities and prevent volatility loss.
Synergies
- Antioxidants (e.g., tocopherols) are recommended to enhance long-term oxidative stability in prone formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed its safety in cosmetic applications at current usage concentrations, provided it is formulated to be non-irritating. It is deemed safe for leave-on products up to 25%. Rigorous studies confirm it is neither genotoxic nor a reproductive or developmental toxicant, and it exhibits no dermal irritancy or sensitization potential.
