2. Active Ingredients

Theaflavins and Thearubigins

The main active ingredients of black tea extract are natural characteristic compounds of theaflavins and thearubigins. These active substances are renowned for powerful antioxidant brightening, free radical scavenging, anti-inflammatory soothing and skin evening repair properties, serving as the core components of the efficacy of black tea.

Theaflavins and thearubigins are key natural active ingredients intensively studied in the industry. Studies have shown that these components can effectively neutralize free radicals in the body and on the skin surface. Free radicals are the main causes of skin oxidative dullness, fine lines, uneven skin tone, slow body metabolism and sub-health conditions, which can effectively improve multiple oxidative damages and skin aging problems.

Natural Polyphenols, Tea Polysaccharides and Organic Acids

Black tea extract also contains abundant natural black tea polyphenols, tea polysaccharides and organic acids, with a mild and mellow natural black tea aroma. These ingredients not only endow the product with a pure and mild tea texture, but also deliver excellent functions of body metabolism regulation, mild nourishment, soothing stabilization and physical conditioning, which gently nourish the skin and body and bring multiple comprehensive maintenance benefits.

3. Appearance and Properties

Color

Conventional-grade black tea extract appears reddish brown to brownish red; high-purity grade presents light reddish brown, and high-precision grade shows pale reddish white, free of impurities and agglomeration.

Form

This product is available in fine powder and concentrated liquid extract. The delicate powder is easy to formulate, suitable for producing dietary supplements, solid functional foods and skin care powder raw materials. The liquid extract features higher concentration and completely retained bioactivity, which is more suitable for deep processing scenarios requiring high concentration and high permeability.

Solubility

Conventional black tea extract powder has moderate water solubility and performs better in dispersion and dissolution in alcohol-based and oil-based systems. Supported by advanced extraction and modification technology, water-soluble black tea extract has achieved stable mass production. It is compatible with various water-based production systems to fully meet the diverse application needs of different industries.

4. Health Benefits

Antioxidant Protection

As mentioned above, theaflavins, thearubigins, polyphenols and tea polysaccharides in black tea extract possess strong antioxidant capacity. They can effectively eliminate free radicals in the body and on the skin, protect cells from oxidative damage, slow down the aging process of the body and skin, and reduce the risks of skin dullness and yellowing, rough sagging, fine line generation and sub-health problems caused by body metabolic disorders.

Anti-inflammatory and Soothing Properties

Multiple studies have confirmed that black tea extract has remarkable anti-inflammatory, soothing and mild stabilizing effects. It can effectively relieve superficial skin dry redness, sensitivity, dullness and roughness. Meanwhile, it assists in regulating mild internal inflammation and alleviating body heat, which contributes greatly to skin barrier repair, fragile skin improvement and metabolic inflammation conditioning.

Body Metabolism and Physical & Mental Conditioning

The natural active ingredients of black tea exert positive regulatory effects on human metabolism and physical and mental status. They help adjust body circulation, relieve physical and mental fatigue, improve listlessness and drowsiness, mildly regulate bodily functions, and ameliorate sub-health conditions caused by irregular schedules, high-fat diet and poor metabolism.

Metabolic Maintenance and Health Care

Organic acids, polyphenols and tea polysaccharides in black tea extract gently regulate human metabolism, balance body circulation, unblock metabolic pathways and accelerate the excretion of excess substances. They alleviate physical heaviness, fatigue, drowsiness and dull complexion caused by slow metabolism and poor circulation, realizing mild full-body mild conditioning and health maintenance.
