|---|---|---|---|
| Tea tree | Melaleuca alternifolia | Terpinen-4-ol ≥30%, cineole ≤15% (ISO 4730) | Acne care, cleansers, first-aid, aromatherapy |
| Eucalyptus (globulus) | Eucalyptus globulus | 1,8-cineole ~70-80% | Cold/decongestant blends, cleaning |
| Cajeput | Melaleuca cajuputi | 1,8-cineole ~50-60% | Respiratory blends, lower cost |
| Niaouli | Melaleuca quinquenervia | 1,8-cineole ~40-60% | Skin/respiratory, gentler cineole |

- Tea tree is more skin-tolerant and better documented for topical antibacterial use than high-cineole eucalyptus
- Cineole-rich oils (eucalyptus, cajeput) are better for "breathe easy" respiratory fragrance but more irritating on skin
- Manuka is a premium niche oil with a different chemical class; tea tree remains the cost-effective workhorse
- Tea tree's lower cineole and high terpinen-4-ol meet the ISO 4730 specification that guarantees its recognized quality
- For most industrial and personal-care programs, tea tree gives the best performance-to-price ratio
