Science
Mechanism of Action
It functions primarily as a stabilizing solvent that facilitates the dissolution of resins and other difficult-to-blend cosmetic ingredients. Due to its high boiling point and low evaporation rate, it acts as an effective fixative, slowing the release of fragrance molecules to provide a more consistent sensory experience.

Dusting Analysis
As this ingredient is a functional solvent rather than an active treatment, it is rarely 'dusted' for marketing purposes. In leave-on facial products, it is typically used at ultra-low concentrations (often below 0.0031%) purely for technical stability.
The Formula
Formulation
Stability
Highly stable at room temperature within standard cosmetic pH ranges. It maintains low viscosity regardless of temperature fluctuations.

Safety
Safety Profile
While safe at cosmetic concentrations, the undiluted raw material is a known ocular and respiratory irritant. CIR safety assessments are based on current low-level usage in leave-on products (under 0.25%).
