Determination of the oxidation stability of lipstick and lip balm

Lipsticks and lip balms consist mainly of natural oils such as seed oils, palm oils or coconut oils. Many manufacturers additionally enhance their product with various vegetable fats, oils and wax. The purpose of these additives is to increase the perceived quality of the products. However, some of these oils and fats are capable to oxidize by autoxidation over time which affects the shelf life and therefore the quality of the products negatively. A reproducible and accurate determination of the oxidation stability using the 892 Professional Rancimat can be realized.
