Ki'Leaft, Berkem's new active ingredient extracted from the kiwi leaf

Berkem Group, a leading player in plant chemistry, announces that its subsidiary Berkem, a French specialist in plant extraction, is launching a new active company, Ki'Leaft. It is an extract of kiwifruit leaves certified cosmos 100% of natural origin, upcycled and from a local production close to the extraction plant of the Berkem Group, in Dordogne. Ki'Leaft meets the needs of the market with its antioxidant, firming, regenerating and barrier function strengthening properties of the skin.

The result of 10 years of Research & Development

As an industrial expert in plant chemistry, the Berkem Group has developed and tested the capabilities of kiwifruit leaf extract. After 10 years of R&D, the various studies have revealed the properties of Ki'Leaft, an active ingredient rich in sugars and containing polyphenols*.

Thus it has been clinically proven that Ki'Leaft offers an immediate tightening effect, that it participates in the regeneration of the skin, strengthens its barrier function as well as its structure, while presenting a strong antioxidant capacity. Ki'Leaft meets the expectations of the cosmetics market by offering benefits for the facial care market (serum, facial care, etc.), which has been growing by 10% worldwide each year since 2020 (source Mintel GNPD – The Future of Facial Skincare, 2022).

Le Kiwi – un peu d’histoire  :
Actinidia chinensis est le nom donné par le botaniste français Jules Emiles Planchon en 1847, dérivé du grec aktis signifiant petit rayon, en référence aux fleurs femelles se déployant comme les rayons d’une roue de vélo.
Originaire de Chine, où il est dégusté depuis plus de 2 000 ans, ce fruit de liane, poussant le long du grand fleuve Yang Tsé Kiang, était connu sous le nom de Yang Tao, la pêche du Yang.
Introduit en Europe au milieu du XVIIIe siècle, il n’est alors connu que comme plante d’ornement et s’acclimate dans les jardins botaniques européens au cours du XIXe.
Cultivé en Nouvelle-Zélande au début du XXe siècle, la terre de ses premiers succès lui donnera le nom de Kiwi, tout comme son oiseau emblématique comme lui, il est petit, marron et poilu.
Aujourd’hui cultivé et consommé à travers le monde, il est apprécié pour son goût, et sa richesse en antioxydants qui fait de lui l’allié santé par excellence. En France, la 1ère récolte à vocation commerciale a eu lieu en 1972 et le Sud Ouest – région la plus propice à sa culture (climat, sol et ensoleillement) – concentre aujourd’hui les trois quarts de la production nationale

The illustration of upcycling for the benefit of research

Nouvelle-Aquitaine accounts for 75% of national kiwifruit production (45,245 tonnes of kiwifruit were produced in France in 2021 – source Agreste) and the vast majority of the leaf of this fruit is thrown away during harvest. With this in mind, Berkem researchers, specialists in plant extraction based in the Dordogne (in Gardonne) as close as possible to kiwifruit farms, investigated, tested and validated the effectiveness of the active ingredient to address the cosmetics market. The Berkem Group thus values kiwi leaves 100% of natural origin, from a controlled and certified organic culture.

" With 30 years of experience in plant extraction, the Berkem Group, integrator of plant chemistry, is constantly seeking to be a forerunner in the development of innovative solutions, particularly in the fields of health, beauty and nutrition. Developing this new active ingredient resulting from upcycling and with remarkable properties meets the demand of customers – professionals and major brands – in cosmetics, while illustrating our Group's CSR strategy. " says Charlène Martin, Marketing Manager, Berkem Group.
