Malassezia yeasts have been shown to metabolize esters when derived from certain combinations of fatty acids or alcohols. Esters undergo hydrolysis after being exposed to Malassezia, allowing the yeasts to metabolize the free fatty acids.12
Sezia's database includes esters derived from fatty acids of the c11-c24 series and a large collection of alkyl groups. The alkyl groups include primary and fatty acid alcohols, various sugar alcohols, polyethers such as PEG and PPG compounds, as well as several ethers.
Sezia matches esters with with up to five ester groups (esters with more than one fatty acid), notably including monoglycerides, polyglycerides, and triglycerides. Sezia also checks for esters derived from the lipophilic substances included in it's database.
