The Standards Australia Committee CH-021 Essential Oils met on the 19th of March 2018 at the Standards Australia office in Pitt St, Sydney. The meeting was attended by:

(1) Southern Cross University (Ashley Dowell);
(2) Australian Tea Tree Industry Association (Richard Davis)
(3) Essential Oil Producers’ Association of Australia (John Fergeus)
(4) Essential Oil Producers’ Association of Australia (Ian Southwell)
(5) Alisa Manassa (Standards Australia)

Discussion regarded:

  • Committee membership
  • Review of the international balloting process
  • Proposed ISO TC 54 meeting in Spain, October 2018
  • Aged Standards: Proposed revision of AS 2116-2004 Oil of Eucalyptus citriodora Hook
  • Assessment of the published ISO 4730:2017(en) Essential oil of Melaleuca, terpinen-4-ol type (Tea Tree oil) and the amendment.

Committee membership
Since the last meeting two key members Dr. Joseph Brophy and Mr. Michael Russell have both resgned from the committee. A number of members have also been relatively silent for a number of years. All members were asked to consider Essential Oils technical specialists who might be able to contribute to CH-021.

Review of current international ballot responses.
Members were encouraged to be more diligent in responding to ISO ballots even if their response was simply an Abstention because of lack of specialist knowledge. The value of voting in ISO ballots was questioned given that responses regarding changes to ISO 770 2002 “Crude or rectified oils of Eucalyptus globulus (Eucalyptus globulus Labill.)” wherein responses to revise the standard to amend a-phellandrene minimum level and include sabinene levels was thwarted as most countries voted to reconfirm the current standard. CH-021 resolved to see if this particular matter can be further discussed at the upcoming ISO TC54 meeting.

Proposed ISO TC 54 meeting in Spain, October 2018: Australian delegates and funding
It was agreed that SAA representation at this meeting was important and that Ian Southwell and Ashley Dowell should be nominated to attend.  Australian Standards will provide some funds towards this delegation attendance but further funds will be sought from EOPAA and possibly SCU.  CH-021 is looking at the potential to nominate AS 4941-2001 Backhousia citriodora essential oil for consideration as the basis for an ISO standard for Essential Oil of Backhousia citriodora.

Aged Standards: Proposed revision of AS 2116-2004 Oil of Eucalyptus citriodora Hook
Although this oil is invariably traded as Eucalyptus citriodora, the correct botanical name is now Corymbia citriodora. It has been suggested that this should be changed in both AS 2116-2004 Oil of Eucalyptus citriodora Hook and in ISO 3044:1997 – Oil of eucalyptus citriodora Hook.

Assessment of the published ISO 4730:2017(en) Essential oil of Melaleuca, terpinen-4-ol type (Tea Tree oil) and the amendment.
This Standard has been well received by the industry despite tighter ranges for 1,8-cineole and terpinen-4-ol. There are some questions about determination of enantiomeric ratio by GCMS.  The ISO method prescribes GCFID.  Ashley Dowell has offered to assist in resolving this enquiry.
The potential for including new standards for emerging Australian essential oils was discussed but the group felt that none of the emerging essential oils were of adequate value to warrant a dedicated AS or ISO method at this stage.  EOPAA’s proposal to develop quality guidelines for emerging Australian essential oils was looked on favorably by the committee.
