Is Butyloctyl Salicylate fungal acne safe?
Butyloctyl Salicylate is generally considered safe for fungal-acne-prone skin. Salicylate ester of a branched C12 Guerbet alcohol. Branching blocks beta-oxidation, as with Isocetyl Alcohol, and salicylate esters are cleared throughout.
Why this verdict
Salicylate ester of a branched C12 Guerbet alcohol. Branching blocks beta-oxidation, as with Isocetyl Alcohol, and salicylate esters are cleared throughout.
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 is Butyloctyl Salicylate considered fungal-acne safe?
Salicylate ester of a branched C12 Guerbet alcohol. Branching blocks beta-oxidation, as with Isocetyl Alcohol, and salicylate esters are cleared throughout. Fungal acne (malassezia folliculitis) is driven by ingredients that supply fatty acids in roughly the C11 to C24 range that the yeast can metabolize; Butyloctyl Salicylate is assessed against that mechanism.
