Quercetin Caprylate

What is Quercetin Caprylate?

Quercetin Caprylate is an ester formed by combining quercetin, a flavonoid polyphenol abundant in plants such as onions, apples, and berries, with caprylic acid, a saturated medium-chain fatty acid sourced from coconut or palm kernel oils. This modification converts the naturally hydrophilic quercetin into a lipophilic compound, improving its compatibility with oil-based cosmetic vehicles like emulsions, serums, and creams. Primarily categorized under antioxidants and emollients in cosmetic ingredient databases, it operates by scavenging reactive oxygen species through its polyphenolic structure, thereby stabilizing susceptible formulation components against degradation. The fatty acid chain imparts emollient qualities, facilitating smoother application and enhancing skin feel, while contributing to overall skin conditioning by promoting suppleness without heavy occlusion.
