Sodium Lauroyl Lactylate and fungal acne
May trigger · Moderate evidence
Why it's a potential trigger
A lauric-acid ester that Malassezia yeast’s fat-splitting enzymes can cut back into C12 food, the same trick behind our sorbitan and glyceryl ester flags.
C12 is this yeast’s prime chain length; the ester form does not hide it.
Evidence strength
Moderate evidence (2/3)
Function
Fatty ester
Fatty esters: split by the yeast’s enzymes into edible fats.

How confident is this call?
Moderate evidence: A lauric-acid ester that this yeast’s fat-splitting enzymes can cut back into C12 food, the same trick behind our sorbitan and glyceryl ester flags.
