Ethylhexyl Palmitate is not automatically unsafe for seborrheic dermatitis, but people following a strict Malassezia-screening routine may prefer to avoid it. It is a silky emollient ester, not a treatment, and direct evidence in seb derm is missing.

Laboratory studies show that Malassezia can use free palmitic acid and can hydrolyse some fatty-acid esters, but they did not test Ethylhexyl Palmitate in a finished cosmetic or on people. That makes the concern theoretical rather than a guaranteed reaction. Consider the product type and stop if a leave-on formula repeatedly worsens itching or redness.
