Why this verdict
Same caution class.
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. See the full trigger list and how we assess ingredients for the reasoning and sources.
