Sorbitan Caprylate

Sorbitan Caprylate's CosIng-listed function is "surfactant - emulsifying": keeps oil and water blended together.

Sorbitan fatty-acid esters (the non-ethoxylated cousins of polysorbates — same fatty-acid-plus-sorbitan backbone, without the polyoxyethylene chains) are flagged by analogy, not by direct evidence: polysorbates (Tweens) are a well-documented Malassezia growth substrate used in classic mycology to tell species apart, but no study we could find has tested plain sorbitan esters (Span-type) the same way. Since the fatty-acid ester bond a lipase would need to hydrolyse is chemically the same in both, it's a reasonable inference that sorbitan esters behave similarly — but it is an inference, not a direct finding. Treat this as a soft, analogy-based patch-test flag rather than an evidenced trigger.

Evidence: Limited evidence.
