Product Protection
Evonik Dr. Straetman’s GmbH specialises in alternative and natural product protection. There are several ways to protect Cosmetics products – multifunctional antimicrobials and preservative blends.
Why We Need Antioxidants
Antioxidants help to protect the oil phase of a Personal Care formulation from oxidation. This prevents against the negative impacts of oxidation such as altered smell, discoloration, loss of function and separation.

Why We Need Chelating Agents
In order to further increase product protection, chelating act synergistically in combination with antioxidants.
Phytic Acid is a natural chelator (and replacement of EDTA) and is able to inactivate metal ions, which increase oxidation rate in cosmetic formulations. Furthermore, it’s highly suitable for rinse-off products because it maintains foaming properties in presence of hard water during application and prevents precipitation of divalent fatty acid salts in soaps.
