Jojoba Esters
Also known as Jojoba Esters, Jojoba Wax, Hydrogenated Jojoba Oil Esters
“CIR Expert Panel says: safe as used in cosmetics.”
Jojoba Esters are the solid wax fraction produced by hydrogenation or interesterification of Simmondsia Chinensis (Jojoba) Seed Oil; they share the same long-chain wax ester chemistry as the parent oil but are solid at room temperature due to saturation. The CIR Expert Panel evaluated Jojoba Esters within the same Amended Final Report (09/2008) that covers jojoba seed oil and jojoba alcohol, concluding the ingredient is safe for cosmetic use without conditions. A 2008 clinical study (PMID 19146603) demonstrated that hydrolyzed jojoba esters synergize with glycerol to provide 24-hour skin moisturization, supporting the emollient efficacy profile of the jojoba ester family. A 2013 dermatology review (PMID 24442052) documents anti-inflammatory, anti-infective, and moisturizing properties of jojoba-derived ingredients in topical applications.
Solid wax ester emollient that provides a dry, non-greasy skin feel; widely used as a natural wax alternative in balms, lip products, and solid formulations
Same sebum-mimetic long-chain wax ester chemistry as jojoba oil; non-comedogenic and compatible with skin lipids
Excellent oxidative stability due to saturated wax ester structure; longer shelf life than conventional plant-oil emollients
Covered under the same CIR safety assessment (Amended Final Report 09/08) as Jojoba Alcohol and Jojoba Seed Oil — well-characterized ingredient family
- · Rare contact sensitization has been documented for jojoba-derived ingredients in individuals with pre-existing plant-wax sensitivities; Jojoba Esters share this low-level risk with the parent oil
