Green Tea Extract Polyphenol

Green Tea Extract Polyphenol is a collection of natural plant compounds extracted from the unfermented leaves of green tea (Camellia sinensis), rich in diverse natural polyphenolic substances. Green Tea Extract Polyphenol finds extensive application in the cosmetics sector due to its exceptional biological activity. These polyphenols constitute the primary contributors to green tea's biological activity, accounting for 20-35% of the dry weight of tea leaves.

Our Green Tea Extract Polyphenol product is designed to provide B2B clients with a high-purity, standardised, and potent cosmetic ingredient, meeting the growing demand for natural, effective skincare solutions. As a natural and potent botanical extract, Green Tea Extract Polyphenols not only effectively combat free radical damage and reduce skin ageing but also soothe sensitive skin while enhancing overall skin health. Their antioxidant activity surpasses that of many other natural ingredients, establishing them as a highly competitive skincare component within the contemporary cosmetics market. 

XI'AN APP-CHEM BIO (TECH) CO., LTD. (APPCHEM) provides Green Tea Extract Polyphenol utilising a mature, reproducible industrial plant extraction process, comprising the following principal steps:

1. Washing
2. Filtering

4. Drying: to prevent high-temperature damage to thermosensitive active ingredients, especially volatile oils.
5. Crushing: (such as 80 mesh) to increase the contact area with the solvent and improve extraction efficiency.
6. Extraction
7. Solid-liquid separation
8. Purification
9. Concentrate
10. Drying
11. Smashing
12. Packaging
13. Finished product

Green Tea Extract Polyphenol possesses extensive and exceptional efficacy within the cosmetics sector, its mechanism of action rooted in its complex chemical composition and multi-targeted biological activity. Primary benefits encompass antioxidant, anti-inflammatory, anti-ageing, photoprotective, sebum-regulating, and skin-texture-improving properties.

• Potent Antioxidant Action

Green tea polyphenols are exceptional natural antioxidants capable of effectively neutralising and scavenging free radicals (such as reactive oxygen species ROS and reactive nitrogen species RNS) generated within the body and on skin exposed to environmental stressors (e.g., ultraviolet radiation, pollution). Green Tea Extract Polyphenol provide hydrogen atoms to bind with free radicals, thereby terminating free radical chain reactions. They also chelate transition metal ions (e.g., iron, copper), preventing their involvement in radical-generating reactions. Concurrently, Green Tea Extract Polyphenol effectively inhibit lipid peroxidation in cell membranes, safeguarding their integrity and function.

• Significant Anti-inflammatory Effects

Green Tea Extract Polyphenol exert anti-inflammatory effects by inhibiting multiple inflammatory mediators and signalling pathways, thereby alleviating skin redness, irritation, and discomfort. Green tea polyphenols inhibit the activation of these key pathways, thereby reducing the expression of pro-inflammatory cytokines (such as IL-1β, IL-6, TNF-α) and inflammatory enzymes (such as cyclooxygenase-2, COX-2, inducible nitric oxide synthase, iNOS). They also suppress the activity of enzymes associated with inflammation and tissue damage, further alleviating inflammatory responses. 

• Comprehensive Anti-Ageing Effects

Green Tea Extract Polyphenol combat skin ageing by protecting against oxidative damage, inhibiting collagen degradation, and promoting cellular renewal. They suppress the activity of matrix metalloproteinases (MMPs) such as MMP-1, MMP-3, and MMP-9, thereby safeguarding collagen and elastin from breakdown. Beyond inhibiting degradation, Green Tea Extract Polyphenol stimulate skin fibroblasts to synthesise new collagen, thereby enhancing skin elasticity and firmness. Through these mechanisms, green tea polyphenols help maintain skin structural integrity, reduce the appearance of wrinkles and fine lines, and improve overall skin elasticity and firmness.

• Exceptional Photoprotective Effects

Green Tea Extract Polyphenol provide effective internal photoprotection for the skin, mitigating damage from ultraviolet (UV) radiation. Possessing inherent UV-absorbing properties, they function as natural UV filters. They also effectively scavenge UVB-induced reactive oxygen species, thereby reducing photo-oxidative damage and inhibiting UV-induced DNA damage (such as the formation of cyclobutanopyrimidine dimers) and inflammatory responses.

• Oil-Controlling and Antimicrobial Effects

Green Tea Extract Polyphenol demonstrate potential for oil control and antimicrobial activity, offering significant benefits for oily and acne-prone skin. Green tea polyphenols inhibit 5-alpha reductase activity, thereby reducing androgen stimulation of sebaceous glands and lowering sebum secretion. Certain catechins exhibit inhibitory effects against multiple bacteria, including Propionibacterium acnes associated with acne, helping to diminish skin inflammation and infection.

Our Green Tea Extract Polyphenol product, with its multifaceted benefits and exceptional performance, finds extensive application across various cosmetic formulations, meeting brands' demand for highly effective, natural active ingredients.
