Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

1,2,4,5,7,8-Hexoxonane, 3,6,9-trimethyl-, 3,6,9-tris(Ethyl and Propyl) derivatives is only used in industrial settings (manufacture, and downstream use) with no wide dispersive uses. We propose to waive all soil tests as there is no exposure to soil compartment.

Chemicals can reach the soil via 3 main routes:

1.     Application of sewage sludge in agriculture.


a.     Manufacture/formulation:

Waste water from the production plant is generally treated on site (at least a physical/chemical treatment, which will neutralize potential residual organic peroxide). This is usually followed by a dedicated onsite biological treatment. The activated sludge originating from these sewage treatment plants is then extracted and treated as chemical waste.

This Legal Entity only imports, there is no manufacturing or formulation by this Legal Entity.


b.     Downstream use:

Due to their reactive and explosive nature, organic peroxides are generally handled under very strict industrial conditions. They are mainly used as cross-linking agents/polymerization initiators for the production of resins/rubbers/polymers. Based upon the fact that organic peroxides are totally consumed during the process (>99%, which is confirmed by the release factor to sewage for curing agents (Emission Scenario Document on Plastic Additives: ENV/JM/MONO(2004)8/REV1, July 2009, Sections 17.1 and 17.2), it is assumed that the soil is not exposed to organic peroxides via use of sludge.


As a consequence, we can assume that soil is not exposed to organic peroxides via the application of sewage sludge in agriculture.


2.     Direct application of chemicals.

Based on the inventory of uses of organic peroxides, there is no direct application of these substances on the soil compartment. Indeed, all uses are within industrial settings.


3.     Deposition from the atmosphere.

Deposition from the atmospheric compartment involves volatilization, vaporization or direct release of a considered substance into the atmosphere. Due to their dangerous intrinsic physico-chemical properties, organic peroxides are carefully handled in (semi-)closed systems and their transport, production and use are ruled by several regulations. This is also in line with the release factor to atmosphere for curing agents (Emission Scenario Document on Plastic Additives: ENV/JM/MONO(2004)8/REV1, July 2009, Sections 17.1 and 17.2). Based on their uses, we assume that deposition on soil from the atmosphere is unexpected.

Based on these arguments no test is proposed for the soil compartment.
