Hydrogenated Jojoba Oil

Hydrogenated jojoba oil is a saturated wax ester used as an emollient/texture agent, typically at a few percent to higher levels in balms, and it is generally well-tolerated and non-stinging even on compromised skin. However, despite a low irritancy profile in patch testing and broad clinical use, plant-derived lipids can still trigger rare irritant or allergic contact reactions in highly sensitized eczema patients, so it cannot be treated as fully inert. Safety Notes: Hydrogenated jojoba oil (jojoba esters) is commonly used at very low levels (~0.05–0.5%) as a slip/skin-feel modifier or structuring aid in leave-on emulsions and color cosmetics, and similarly low levels can appear in rinse-off cleansers. At the high end, consumer-available anhydrous balms, salves, stick products (lip balms, deodorant sticks), and high-wax barrier ointments can use hydrogenated jojoba oil as a primary structurant/emollient, reaching ~20–60% depending on hardness targets and blend with other waxes/butters. There is no specific EU/FDA maximum for this cosmetic ingredient, so the observed range is driven mainly by sensory and physical stability constraints (viscosity/gel strength) rather than regulation.
