C18-38 ALKYL HYDROXYSTEAROYL STEARATE
Is C18-38 ALKYL HYDROXYSTEAROYL STEARATE safe for seborrheic dermatitis?
There is not enough applicable seb derm evidence to give this compound ester a clear general recommendation. Its emollient and texture-related functions concern a finished formula, rather than an independent treatment effect.
Its fatty-acid-containing composition raises a theoretical screening concern, while its modified structure leaves availability to Malassezia unresolved. Work on selected simpler substrates does not demonstrate feeding from this material or a human flare. Consider the complete product and your response to it, and ask for advice about persistent irritation.
