Oxidation Stability of Fragrance Ingredients
Aldehydes are air-sensitive materials often found in fragrance compositions and may undergo autoxidation. This degradation process can result in discoloration, viscosity changes, malodor and decreased efficacy of a fragrance composition.
This Application Report describes the determination of the oxidation stability of two fragrance ingredients with different antioxidants.
The rapid small scale oxidation tester, RapidOxy 100, is a fast, safe and user-friendly alternative to traditional stability test methods. The instrument measures the induction period, which can be used as an indication of the oxidation and storage stability. Compared to other oxidation and storage stability test methods, the RapidOxy 100 procedure requires only a small sample quantity to give exact test results in a short period of time.
The RapidOxy 100 artificially accelerates the oxidation process by using increased temperature and oxygen pressure. It is a rapid test method to determine oxidation stability without preliminary sample preparation.
Aldehydes are air-sensitive materials often found in fragrance compositions. In the presence of oxygen, aldehydes may undergo autoxidative 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.
