Table 1. Oxidative stability index (OSI*) of emollients

Emollient
OSI
Almond oil 7.6
Borage oil 4.7
Castor oil 21.6
High oleic safflower oil 12.0
Jojoba oil 34.0
Olive oil 3.9
Macadamia oil 72.0
Soybean oil 6.0

*The OSI is determined as the number of hours before the test emollient begins rapid oxidation at 110°C; larger values represent higher oxidative stability.
