Polyquaternium-7 and fungal acne
No known trigger
Why it's not a known trigger
A cationic acrylamide copolymer with no fatty side chains; same neutral-polymer basis as the ruled Polyquaternium-10 row. Added as its own row (not an alias) because it previously fuzzy-matched PQ-10 and the v31 PQ-51 row would have tied that fuzzy match into silence — near-twin polymers stay explicit.

Questions
Does Polyquaternium-7 trigger fungal acne?
No known trigger: A cationic acrylamide copolymer with no fatty side chains; same neutral-polymer basis as the ruled Polyquaternium-10 row. Added as its own row (not an alias) because it previously fuzzy-matched PQ-10 and the v31 PQ-51 row would have tied that fuzzy match into silence — near-twin polymers stay explicit.
Does Polyquaternium-7 feed Malassezia?
No known link: Polyquaternium-7 is judged with no known trigger. One screened ingredient is not a product verdict — when in doubt, ask a dermatologist.
Is this medical advice?
No. We screen ingredient lists; we never diagnose, treat, or certify products. When in doubt, ask a dermatologist.
