Fatty Acids
Malassezia yeasts grow in the presence of fatty acids with carbon chain lengths of 11-24.123
Please note: The various species of Malassezia have different metabolic needs. An ingredient which will feed one species may not feed another. Concentration is also variable in the effect a fatty acid may have on the growth of Malassezia. At this time, Sezia does not make such differentiations. The ingredient checker will flag any ingredient known to feed any species in any concentration.
