Science
Mechanism of Action
This specialized form of quercetin, specifically Quercetin 3,7-dimethyl ether 4′-glucoside (QDG), operates on the skin by significantly inhibiting inflammation-related cytokines and chemokines. It also actively enhances the activation of crucial skin barrier factors and attenuates the phosphorylation inhibition of upstream cytokines and nuclear factor-κB expression. Broadly, related quercetin compounds exhibit antioxidant properties by mitigating lipid peroxidation and oxidative damage, alongside anti-inflammatory effects achieved through the inhibition of inflammatory receptors and their signaling pathways.

The Formula
Formulation
Stability
While specific stability data for Quercetin Dimethyl Ether Glucoside is currently not documented, its glucoside (sugar) moiety typically improves water solubility compared to its aglycone. It is important to note that the parent compound, quercetin, has limited stability, being stable for approximately 4.5 hours within a pH range of 6.0-8.0 when stored at 4°C in the dark. Formulators should consider these general characteristics of the quercetin family.
Safety
Safety Profile
No specific safety assessments from major regulatory bodies such as CIR, SCCS, or FDA have been found for Quercetin Dimethyl Ether Glucoside. General quercetin has shown genotoxic effects in certain *in vitro* assays but not in oral studies, and it is no longer considered carcinogenic. Further targeted safety assessments for this specific derivative would enhance its profile.
