Tè verde (Camellia sinensis (L.) Kuntze) foglia is the extract obtained by an industrial process from the leaves of Camellia sinensis.
Camellia sinensis is the seedling from which tea (green, black oolong and others) is extracted. It is widely used for ethnopharmacological purposes mainly due to the presence of bioactive components such as phenolic compounds (gallic acid, p-cumaric acid and caffeic acid), purine alkaloids (theobromine, caffeine and theophylline), anthocyanins, flavonol glycosides (kaempferol, myricetin and quercetin), flavonoids (catechins).

What it is used for and where
Cosmetics  
Antimicrobial agent. This ingredient is able to suppress or inhibit the growth and replication of a broad spectrum of microorganisms such as bacteria, fungi and viruses by making the stratum corneum temporarily bactericidal and fungicidal.

Cosmetic astringent. This ingredient exerts a direct effect on the skin by tightening dilated pores by contracting stratum corneum cells and removing superfluous oil.

Fragrance. It plays a very important role in the formulation of cosmetic products as it allows perfume to be enhanced, masked or added to the final product, improving its commercial viability. The consumer always expects to find a pleasant scent in a cosmetic product.

Light stabilizer. It prevents light from degrading light-sensitive components and slows down degradation reactions that have already begun. The mechanism is, in a way, similar to antioxidants and the effectiveness depends on the.complexity of the formulation and the density of the product.

Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
