Is Ethyl Hexanediol fungal acne safe?
Ethyl Hexanediol is generally considered safe for fungal-acne-prone skin. C8 branched aliphatic diol preservative-booster/solvent; chain length below the C11-C24 utilization window and contains only free -OH (no ester or fatty-acid bond); same safe class as 1,2-Hexanediol already in this section. NOTE: distinct ingredient from Ethylhexylglycerin - sometimes confused but Ethylhexylglycerin is a separate row in 7j.
Also known as 2-Ethyl-1, 3-Hexanediol, Octanediol
Why this verdict

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 Ethyl Hexanediol considered fungal-acne safe?
C8 branched aliphatic diol preservative-booster/solvent; chain length below the C11-C24 utilization window and contains only free -OH (no ester or fatty-acid bond); same safe class as 1,2-Hexanediol already in this section. NOTE: distinct ingredient from Ethylhexylglycerin - sometimes confused but Ethylhexylglycerin is a separate row in 7j. Fungal acne (malassezia folliculitis) is driven by ingredients that supply fatty acids in roughly the C11 to C24 range that the yeast can metabolize; Ethyl Hexanediol is assessed against that mechanism.
