Jojoba is a plant in the Simmondsiaceae family of plants. It is grown specifically for jojoba to be harvested for the liquid wax in its seed. It is used as a carrier oil for essential oils used in massage and aromatherapy.
Simmondsin is a component of jojoba oil. It is toxic to most mammals including humans. It is not fit for human consumption and can cause diarrhoea in humans as it cannot be digested.
It is generally not the main culprit in allergic contact dermatitis, it is much more likely to be one of the essential oils it is commonly mixed with.
Jojoba oil is often associated with contact allergic dermatitis, but this is usually linked to the essential oils it is linked with and not the jojoba oil itself.
There are no allergens currently associated with jojoba oil.
