Simmondsia Chinensis (Jojoba) Seed Oil is obtained by pressing the seed kernels of an evergreen shrub native to the Sonoran and Mojave deserts of Arizona, California and Mexico. This oil is different from other common plant oils in that it is composed almost completely (97%) of wax esters of monounsaturated, straight-chain acids and alcohols with high molecular weights (carbon chain lengths from 36 to 46). This makes Jojoba Oil and its derivative Jojoba Esters more similar to sebum and whale oil than to traditional vegetable oils.

The CIR Expert Panel reviewed a number of studies that indicated low acute and subchronic toxicity of Simmondsia Chinensis (Jojoba) Seed Oil. Undiluted Simmondsia Chinensis (Jojoba) Seed Oil was not a skin irritant. In a maximization test, no sensitization reactions were observed with Jojoba Alcohol. Jojoba Alcohol and mixture of Jojoba Oil and Hydrogenated Jojoba Oil were not mutagenic in bacterial assays. Tests of topical products containing Simmondsia Chinensis (Jojoba) Seed Oil found them to be nonirritants and nonsensitizers to humans. Sensitization to undiluted Jojoba Oil was not observed.
