Anton Paar has published a report detailing the use of its RapidOxy in determinating of the oxidation stability of two fragrance ingredients with different antioxidants.
Aldehydes are air-sensitive materials often found in fragrance compositions. In the presence of oxygen, aldehydes can undergo auto-oxidative decomposition, leading to an increasing amount of radical chain reactions. This degradation process can result in discoloration, viscosity changes, malodor and decreased efficacy of a fragrance composition. To prevent such undesirable effects, aldehydes need to be protected against autoxidation.
For the report, the benefit of three antioxidants was assessed on two different aldehydes commonly used in fragrance composition.
