Black tea extract (CAS 188265-33-0) is a natural antioxidant derived from fermented tea leaves, rich in theaflavins and tea polyphenols. In food & beverage, it acts as a natural preservative and colorant, replacing synthetic antioxidants (BHA, BHT) in functional drinks, confectionery, and baked goods. In cosmetics, it serves as an anti-aging, anti-inflammatory, and skin-brightening ingredient in toners, serums, and creams, protecting skin from UV damage and reducing wrinkles. In nutraceuticals, it supports cardiovascular health (lowering blood pressure and lipids), boosts immunity, and aids weight management by inhibiting fat absorption. It also finds use in oral care products for reducing plaque and bad breath.
