Polyquaternium-44 and fungal acne

No known trigger

Why it's not a known trigger

A vinylpyrrolidone/quaternised vinylimidazole conditioning polymer with a methylsulfate counterion and no fatty chains; same neutral-polymer basis as the ruled Polyquaternium-10 and -51 rows.

Added B-vitamin with no lipid fraction; nothing for this yeast to feed on. Settle-at-neutral unless a Malassezia vitamin-requirement study says otherwise.
