Laurtrimonium Chloride and fungal acne
No known trigger
Why it's not a known trigger
C12 alkyl quaternary ammonium salt used as a preservative/antistatic: the fatty chain is covalently bound to nitrogen, so it is not a free fatty acid and lipases cannot liberate one; it sits at preservative levels.
A preservative and conditioning agent; its fatty chain is tied to a nitrogen atom, so it is not a fat Malassezia can use, and it appears only at very low levels.
