Is Jojoba Wax PEG-120 Esters fungal acne safe?
Jojoba Wax PEG-120 Esters is best avoided for fungal-acne-prone skin. PEG-120 ethoxylated jojoba wax esters; despite high EO count, Malassezia lipases hydrolyze the jojoba ester linkage to release C20-C22 fatty acids/alcohols squarely in the metabolic window.

Why this verdict
PEG-120 ethoxylated jojoba wax esters; despite high EO count, Malassezia lipases hydrolyze the jojoba ester linkage to release C20-C22 fatty acids/alcohols squarely in the metabolic window.
Fungal acne, properly called malassezia folliculitis, is driven by a yeast that feeds on fatty acids in roughly the C11 to C24 range. An ingredient is a concern when it can supply usable fatty acids in that window, and it is generally fine when it cannot. Chain length and ethoxylation can both change the verdict, which is why the chemical family alone does not decide it.

Why does Jojoba Wax PEG-120 Esters trigger fungal acne?
PEG-120 ethoxylated jojoba wax esters; despite high EO count, Malassezia lipases hydrolyze the jojoba ester linkage to release C20-C22 fatty acids/alcohols squarely in the metabolic window. Fungal acne (malassezia folliculitis) is driven by ingredients that supply fatty acids in roughly the C11 to C24 range that the yeast can metabolize; Jojoba Wax PEG-120 Esters is assessed against that mechanism.
What can I use instead of Jojoba Wax PEG-120 Esters?
Fungal-acne-safe alternatives in the same category include Ceteareth-20, Cocamidopropyl Betaine, Isoceteth-20, PEG-40 Hydrogenated Castor Oil. Fungalscan suggests swaps like these automatically after an avoid or caution result.
