Is Ethoxydiglycol fungal acne safe?
Ethoxydiglycol is generally considered safe for fungal-acne-prone skin. Small C6 glycol-ether solvent / penetration enhancer (CAS 111-90-0); pure ether/diol chain with terminal -OH, no fatty acid - short carbon chain falls well below the C11-C24 Malassezia utilization window and the in vitro Schwartz study explicitly cleared glycol ethers.
Also known as DEGEE, Diethylene Glycol Monoethyl Ether, 2-(2-Ethoxyethoxy)Ethanol, Transcutol
Why this verdict
Small C6 glycol-ether solvent / penetration enhancer (CAS 111-90-0); pure ether/diol chain with terminal -OH, no fatty acid - short carbon chain falls well below the C11-C24 Malassezia utilization window and the in vitro Schwartz study explicitly cleared glycol ethers.
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.

Why is Ethoxydiglycol considered fungal-acne safe?
Small C6 glycol-ether solvent / penetration enhancer (CAS 111-90-0); pure ether/diol chain with terminal -OH, no fatty acid - short carbon chain falls well below the C11-C24 Malassezia utilization window and the in vitro Schwartz study explicitly cleared glycol ethers. Fungal acne (malassezia folliculitis) is driven by ingredients that supply fatty acids in roughly the C11 to C24 range that the yeast can metabolize; Ethoxydiglycol is assessed against that mechanism.
