The BPR controlling the use of biocides in the EU
**Important information about the redefinition of Citriodiol® under the BPR**
Citriodiol® was originally notified under the BPD/R as “a mixture of cis- and trans-p-menthane-3,8-diol/citriodiol” under the CAS No. 42822-86-6. As of October 2016, it has been redefined as “Eucalyptus citriodora oil, hydrated, cyclized” under the CAS No. 1245629-80-4 (abbreviated for informal use as EC Oil (H/C)) to better reflect its botanic origin.
The whole substance i.e. Citriodiol® (which includes a minimum 64% p-menthane-3,8-diol), sourced from Eucalyptus citriodora oil is continuing to be supported by Citrefine under the new name “Eucalyptus citriodora oil, hydrated, cyclized”.

What is The European Biocidal Products Regulation (EU) 528/2012?
The European Biocidal Products Regulation (BPR) controls the use of all biocides (substances or microorganisms which deter, render harmless, or exert a controlling effect on any harmful organism - like a bug spray which stops mosquitoes from biting) manufactured or sold within the European Union. It came into force on 1 September 2013, replacing the European Biocidal Products Directive 98/8/EC (BPD), and is now law in every European member state.
The aim of the BPR is to limit the use of those biocides which are unable to meet strict requirements for efficacy (showing it really works), consumer health and safety to the environment. There are many categories of biocides, ranging from hand sanitizers to wood preservatives and rodent control. Insect repellents fall within product type 19 (PT19) of the BPR, which covers repellents and attractants. Every biocide being placed on the market must now be authorised through a uniform submission and review process. This is true whether your product comes from nature or is entirely synthesised.
The use of other substances such as neem oil, citronella oil and tea tree oil is no longer allowed for use in personal insect repellents as they were not notified under the BPD and are not being supported through the authorisation process.

The earliest anticipated date for an inclusion decision on Citriodiol® is in April 2020
What is the current status of Citriodiol® under the BPR?
The Citriodiol® dossier is currently under evaluation by the UK Health & Safety Executive (HSE), its evaluating Competent Authority, however as a result of Brexit, ECHA have identified the Czech Republic competent authority to take over the dossier. We do not yet have a timeline from the CZCA as to how the evaluation of the EC Oil (H/C) dossier will fit into their schedule, however we estimate that the earliest anticipated date for an inclusion decision would be April of 2020. This is only an estimate as the actual date will be determined by the authorities and Member States. It is therefore in the "transitional period" where products must follow national regulatory requirements.

Gaining access to data to support your registrations
If you have your own formulation, you will probably need to develop your own phys/chem and efficacy data to support your product submission. You may be able to rely on Citrefine's data to support some or all of the toxicity endpoints required.
If you wish to rely on one of our formulations, we can assist further as we have a large body of data to support such product registrations.
Relying on our data typically involves our providing you with citation rights to certain studies through a letter of access (LoA). Depending on the access required, we may ask you to sign an agreement that gives us your commitment that you will purchase the Citriodiol® you require for your product from us. There may also be a data access fee. Please contact us to discuss these terms in more detail.

The regulatory situation in the USA and the rest of the World
In the United States, Citriodiol® is more commonly known as Oil of Lemon Eucalyptus, or OLE. It was first registered with the Environmental Protection Agency in 2002. Since then, it has been sold nationwide in a 30% or 40% formula, and it is the only naturally sourced repellent whose efficacy against the mosquitoes that carry the Zika virus and West Nile disease, that is recognised by the Centers for Disease Control and Prevention. Please see this direct link to a published document on the US CDC website.
At Citrefine’s request the description of Citriodiol® in Canada has been formerly changed by PMRA from p-menthane-3,8-diol and related oil of lemon eucalyptus compounds, to Oil of lemon eucalyptus, hydrated, cyclized (effective October 2017). This new name is more consistent with chemical identification used by authorities in the US, EU and other jurisdictions and emphasises that it is Citriodiol®’s inclusion of the many naturally occurring components found in the botanical source that give it its remarkable efficacy, and not the PMD content alone.
Rest of the World
Citriodiol® based products for dermal application to humans have been approved by the regulatory authorities in a number of countries including the USA, Australia, Spain, Sweden and the Netherlands. Please contact us for further information about any of these countries, or if you have any questions regarding other countries not listed here. We will be able to discuss with you how best to achieve your regulatory goals.
