Myricetin

Myricetin (CAS 529-44-2, EC 208-463-2, formula C15H10O8) is a naturally occurring plant flavonoid also known as Myricetol, Myricitin, and NSC 407290. It carries no assigned E-code and is classified under HS code 29329990. It is commercially sourced from plant materials including bayberry bark and certain herbs.

In personal care formulations, myricetin functions as an antioxidant by scavenging free radicals and chelating pro-oxidant metal ions, helping to stabilize emulsions and protect active ingredients from oxidative degradation. In food and nutraceutical applications, it acts as a natural colorant contributing brown-yellow hues while simultaneously providing antioxidant protection to lipid-containing matrices.

Myricetin is supplied as a brown-yellow to brown-green crystalline powder in standard laboratory and bulk quantities. Procurement professionals should verify compliance with REACH regulations and confirm supplier documentation for cosmetic-grade or food-grade specifications, as no pharmacopoeial monograph is universally standardized for this material.
