Overview
Myricetin (CAS 529-44-2 ), also known as Myricetol, is a naturally occurring flavonoid extracted primarily from berries, grapes, herbs, and bark. It functions as a potent antioxidant and natural colorant across food, cosmetic, and nutraceutical applications.
Demand is driven by the clean-label trend and growing interest in plant-derived bioactive ingredients. In nutraceutical and dietary supplement formulations, it is incorporated as an active antioxidant ingredient in capsules, tablets, and functional food products.
Cosmetic formulators use it as a stabilizing antioxidant in skin care products, where it helps protect formulations from oxidative degradation. It also contributes natural pigmentation to creams and serums within the personal care sector.
The food and beverage industry employs it as a natural colorant and flavoring agent in functional beverages, fortified foods, and specialty health products. It meets rigorous industry requirements for safety and efficacy in these applications.
Pharmaceutical researchers and contract manufacturers source it as a reference standard or active botanical extract for investigational formulations. These projects often target oxidative stress pathways using high-purity botanical compounds.
The product is commercially available as a fine yellow to yellowish-green powder. Standard supply grades include food-grade and technical-grade material, with purity levels typically ranging from 95% to 98%+ as confirmed by HPLC.
Bulk quantities are available for industrial buyers, with smaller research quantities offered for formulation development. Our supply chain ensures consistent quality and documentation for global distribution and manufacturing needs.
