Double usage in Scent & Care
The circular economy also plays a major role in the Scent & Care segment. Because certain cosmetic ingredients are meant to be odorless, valuable materials are left over when the raw materials are purified. In order to utilize these more consistently, researchers and developers are looking for new solutions in many places. For example, there are experiments with substances from butter and vegetable oil production in Brazil, and with blossom water from essential oil production, to find materials for fragrance production.
The experts have already made great progress with ginger, which comes from Madagascar and is 100 % traceable and certified organic. “We use a ‘green’ solvent, supercritical carbon dioxide, which can effuse through solids like a gas, and dissolve materials like a liquid. We thus extract two products from the ginger root,” Benoît Join explains about the procedure. “In this way, we obtain an active ingredient with cosmetic properties that is included in our product range under the name SymVital® Mada, as well as an extract with a strong ginger smell, which can be used like an essential oil.” But the process goes even further, explains the Director of Natural Ingredients and Oral Care Innovation from the Scent & Care segment. After extraction, the resulting biomass, which contains the fibers from the roots, can be reused for Cosmetic application. Join describes other advantages: “For the farmers, who used to grow mainly vanilla, ginger represents a diversification of their income.” “The double usage of the material naturally makes it even more valuable for all sides.”
