Case study

Valorization of a co-product from the manufacture of cork stoppers: creation, production and marketing of an innovative, patented and objectified cosmetic active ingredient.

Objective:

To find a valorization of a co-product resulting from the treatment of the cork stoppers carried out by the company DIAM BOUCHAGE. The partnership between DIAM BOUCHAGE and OLEOS-HALLSTAR has made it possible to evaluate the cosmetic potential of this co-product in the form of a wax containing bioactive cork compounds. The industrial development led to the filing of a European application patent in 2014. The ingredient named DIAM Oléoactif® is a natural concentrate of anti-inflammatory compounds adapted to the care of sensitive and reactive skin.

Context:

For OLEOS HALLSTAR France and DIAM-BOUCHAGE, the challenge was cosmetic innovation via eco-responsible green processes of a co-product of the cork treatment. Among the known compounds of cork is very often valorized the suberin. In this project, other non-volatile cork compounds were valorized, in particular triterpenes with anti-inflammatory and antibacterial activity and antioxidant polyphenols present in the leaves and flowers of the tree. The project enabled the implementation of an integrated chain from the harvesting of cork in Portugal and the collection of leaves and flowers to the recovery in the form of an innovative cosmetic active ingredient.
