Cajeput Oil Composition vs. Tea Tree Oil
Tea tree oils are extracted from Melaleuca alternifolia while cajeput is from Melaleuca Cajuputi or Melaleuca Leucadendra ( var. cajuputi).
Cajeput contains higher concentrations of 1,8 Cineole (Eucalyptol), limonene and alpha-Terpineol. Tea tree oil contains more Terpinen-4-ol and gamma-Terpinene. Therefore, cajeput has some properties similar to those found in Eucalyptus (from the Eucalyptol) and Lemon (from the limonene).

1,8-Cineole 44.8%– 60.2%
Alpha-Terpineol 5.9%– 12.5%
Limonene 4.5%– 8.9%

Gamma-Terpinene 10.0%– 28.0%
1,8-Cineole 3.0%– 3.6%
Para-Cymene 0.5%– 12.0%
Alpha-Terpinene 7.9%– 10.4%
