Simmondsia Chinensis Butter

Simmondsia Chinensis Butter (jojoba-derived butter) functions as an emollient/occlusive and is typically used at a few percent up to higher levels in balms; it is generally well tolerated and supportive for barrier-compromised skin. Clinical experience and patch-testing data for jojoba derivatives suggest low irritancy, but rare allergic/contact dermatitis can occur—sometimes due to oxidation products or formulation impurities—so it is not fully “inert.” For high-sensitivity populations (eczema, impaired barrier), this fits best as very gentle with a small but nonzero risk. Safety Notes: In commercial skincare, Simmondsia Chinensis (Jojoba) Butter is often used at low levels (~0.1–1%) as an emollient/structuring lipid in lotions, creams, cleansers, and lip products where it contributes slip without strongly impacting rheology or cost. Mid-to-high levels (5–30%) are common in richer body butters, balms, and barrier creams as a primary lipid phase component. The upper end includes consumer-available “100% jojoba butter” or anhydrous balm-style products marketed as single-ingredient butters; rinse-off products typically stay at the low end due to deposition/economics and the need for surfactant compatibility, while leave-on anhydrous formats can reach the maximum.
