Acetyl Tributyl Citrate keeps its lower-concern label for seborrheic dermatitis. It helps films stay flexible and improves product spread, but it does not treat yeast or inflammation.

This is an ester of citric acid and short butyl groups, not a long-chain fatty-acid ester. The practical Malassezia lipid screen therefore does not apply by the word ester alone. No exact human seb derm or ingredient-specific yeast study was found, making the complete formula and exposure more useful than this ingredient name in isolation.
