Science
Mechanism of Action
As a large-molecule lipophilic glycol, it integrates into the skin's lipid bilayer to fill intercellular voids and create a smoother surface texture. Beyond simple emolliency, it stabilizes emulsions by reducing interfacial tension and optimizes the dielectric constant of the oil phase, which prevents the degradation of volatile UV filters and improves overall photostability.

Clinical Evidence

Key findings
- 01 Significant reduction in transepidermal water loss (TEWL) achieved through the promotion of ortho-rhombic lamellar crystalline structures in the skin barrier.
- 02 Acts as a photostability booster for UV filters, specifically improving the SPF/PFA ratio in sunscreen systems.
- 03 Large-scale patch testing (n=224) confirmed a lack of Type IV dermal reactions, demonstrating exceptional skin compatibility.

Dusting Analysis
C14-18 Glycol is rarely 'dusted' because it serves a functional role in emulsion stability; however, concentrations below 0.5% may fail to provide the meaningful barrier support and photostabilization benefits found in clinical research.
The Formula
Formulation
Stability
Exhibits excellent thermal and hydrolytic stability across a broad pH spectrum, making it ideal for both acidic and alkaline formulations.
Synergies
- Avobenzone
- UV Filters
- Ceramides
- Plant Oils
Conflicts
- Carbomer (may reduce viscosity at high concentrations)
Safety
Safety Profile
While safe up to 40% per CIR guidelines, standard cosmetic efficacy is reached at levels under 10%.
