Description

Tea Polyphenol CAS NO 84650-60-2 is a complex mixture of polyphenolic compounds, primarily catechins, extracted from the leaves of the tea plant (*Camellia sinensis*). This natural extract is highly valued for its potent antioxidant and free radical scavenging properties, making it a critical functional ingredient across multiple industries. It is essential for manufacturers in the nutraceutical, cosmetic, food & beverage, and pharmaceutical sectors seeking to enhance product efficacy and consumer appeal with a bioactive, plant-derived component.

Application

• Nutraceuticals & Dietary Supplements: Used as a key active ingredient in capsules, tablets, and powders for its antioxidant support and potential health-promoting benefits.
• Cosmetics & Personal Care: Incorporated into anti-aging creams, serums, sunscreens, and lotions for its skin-protective, anti-inflammatory, and collagen-stabilizing effects.
• Functional Foods & Beverages: Added to health drinks, sports nutrition products, and fortified foods to provide antioxidant value and extend shelf life.
• Pharmaceutical Intermediates: Serves as a starting material or active pharmaceutical ingredient (API) in research and formulations targeting oxidative stress-related conditions.
• Animal Feed Additives: Utilized to improve animal health, enhance immunity, and act as a natural preservative in feed formulations.
• Industrial Antioxidants: Applied in specialty applications where a natural, biodegradable antioxidant is required to prevent oxidation in sensitive materials.
