About this composition

This profile is anchored to a public COA/technical pack for Cajeput oil with 1,8-cineole assay and identified allergen constituents, then paired with a current IFRA 51 certificate for the oil-level leave-on maximum. The profile is cineole-dominant with limonene, alpha-terpineol, alpha-pinene, linalool, and myrcene as the next quantified markers available in the public documents.
