Science
Mechanism of Action
As a glyceryl ester, Glyceryl Pentadecanoate primarily acts on the skin through its glycerol backbone, which functions as a humectant. This contributes to improved stratum corneum hydration, enhanced skin barrier function, and better mechanical properties of the skin. Beyond its skin conditioning role, it also works as an effective cleansing agent, aiding in the removal of impurities, and as an emulsifier to create stable product textures. Additionally, it can serve as a viscosity increasing agent, influencing the thickness and feel of cosmetic formulations.

Stability
No specific optimal pH range for Glyceryl Pentadecanoate's stability has been identified. However, its classification as an emulsifier indicates it possesses both hydrophilic and lipophilic characteristics, crucial for blending immiscible phases. General insights suggest that the stability of glycerol, a component of glyceryl esters, can be optimized at a pH range of 4-5.5 or above 10.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Glyceryl Pentadecanoate, concluding it safe for use in cosmetics under current practices and concentrations, as part of a broader review of glyceryl monoesters and triglycerides. EWG Skin Deep® categorizes this ingredient with a 'LOW' concern for issues such as cancer, allergies & immunotoxicity, and developmental & reproductive toxicity. However, a 'MODERATE' concern for use restrictions is noted specifically for inhalable product forms due to potential respiratory considerations. No explicit maximum concentration limits are available from SCCS or FDA for topical application.
