Is Sodium Cocoyl Glycinate fungal acne safe?
Sodium Cocoyl Glycinate is best used with caution for fungal-acne-prone skin. Coco-derived (C12-C14) acyl chain amide-bonded to glycine. Follows Sodium Cocoyl Glutamate, the closest structural analog. This family is not internally consistent here - cocoyl glutamate is caution while cocamidopropyl betaine and cocoyl isethionate are safe, all of them stable coco amides - so caution rather than a confident call either way.

Fungal acne, properly called malassezia folliculitis, is driven by a yeast that feeds on fatty acids in roughly the C11 to C24 range. An ingredient is a concern when it can supply usable fatty acids in that window, and it is generally fine when it cannot. Chain length and ethoxylation can both change the verdict, which is why the chemical family alone does not decide it. See the full trigger list and how we assess ingredients for the reasoning and sources.

Frequently asked questions
Is Sodium Cocoyl Glycinate safe for fungal acne?

Follows Sodium Cocoyl Glutamate, the closest structural analog. This family is not internally consistent here - cocoyl glutamate is caution while cocamidopropyl betaine and cocoyl isethionate are safe, all of them stable coco amides - so caution rather than a confident call either way.

Why does Sodium Cocoyl Glycinate trigger fungal acne?
Coco-derived (C12-C14) acyl chain amide-bonded to glycine. Follows Sodium Cocoyl Glutamate, the closest structural analog. This family is not internally consistent here - cocoyl glutamate is caution while cocamidopropyl betaine and cocoyl isethionate are safe, all of them stable coco amides - so caution rather than a confident call either way. Fungal acne (malassezia folliculitis) is driven by ingredients that supply fatty acids in roughly the C11 to C24 range that the yeast can metabolize; Sodium Cocoyl Glycinate is assessed against that mechanism.
What can I use instead of Sodium Cocoyl Glycinate?
Fungal-acne-safe alternatives in the same category include Asiaticoside, Cholesterol, Cocamidopropyl Hydroxysultaine, Fructooligosaccharides. Fungalscan suggests swaps like these automatically after an avoid or caution result.
