About this composition

This profile is specific to the ester-rich Roman chamomile chemotype and not the azulene/bisabolol-rich German chamomile type. EMA's assessment report remains the strongest open quantitative composition source and describes a profile dominated by low-molecular-weight angelates, tiglates, and isobutyrates. Open IFRA certificates for Roman chamomile confirm that public market material can be used at substantial leave-on levels, consistent with the archive's treatment of this oil as comparatively gentle within chamomile essential oils.
