Is PEG-7 Trimethylolpropane Coconut Ether fungal acne safe?

Why this verdict
Coconut-derived (C12-C14) ether with only 7 EO units. Directly parallel to PEG-7 Glyceryl Cocoate.
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.

Frequently asked questions
Is PEG-7 Trimethylolpropane Coconut Ether safe for fungal acne?
PEG-7 Trimethylolpropane Coconut Ether is best avoided for fungal-acne-prone skin. Coconut-derived (C12-C14) ether with only 7 EO units. Directly parallel to PEG-7 Glyceryl Cocoate. This is informational only and not a diagnosis; suitability varies by person and formulation.
Why does PEG-7 Trimethylolpropane Coconut Ether trigger fungal acne?
Coconut-derived (C12-C14) ether with only 7 EO units. Directly parallel to PEG-7 Glyceryl Cocoate. Fungal acne (malassezia folliculitis) is driven by ingredients that supply fatty acids in roughly the C11 to C24 range that the yeast can metabolize; PEG-7 Trimethylolpropane Coconut Ether is assessed against that mechanism.
What can I use instead of PEG-7 Trimethylolpropane Coconut Ether?
