Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Physical & Chemical properties

Endpoint summary

Administrative data

Description of key information

Physico-chemical properties of the substance were determined from experimental testing where relevant, or based on constituent approach when considered more appropriate for an UVCB substance. Some endpoints were waived, based on chemical structure of the major constituents (hydrocarbons, esters).

The substance is a low melting solid at ambient temperature, with very low volatility.

In water, it has very low solubility, and is much less dense, with no surface-active properties anticipated (i.e. excess will floate).

It is considered to have bioaccumulation potential and aquatic chronic toxicity, based on CLP criteria.

It is NOT classified as dangerous with regard to physical hazards, based on CLP criteria.

Additional information

Summary of relevant physico-chemical properties:





Pale brown, wax-like, solid.

Melting point

(OECD102/EU A1, DSC)

ca 25 - 72°C

Boiling point

(OECD103/EU A2, DSC)

ca 338 - 360°C under N2.

Relative density

(OECD109/EU A3, pycnometer with replacement liquid)

d20/4 = 0.9452

Vapour pressure

(constituent approach)

UVCB regarded as having very low volatility (< 0.01 Pa).

Partition coefficient

(OECD117/EU A24, HPLC pre-test only)

Not feasible, not soluble in organic solvents/water mixes (high Log Kow expected).

Water solubility

(constituent approach)

UVCB regarded as having very low solubility (<< 1 mg/L).

Surface tension

(data waiving)

No potential (based on chemical structure of major constituents, insoluble and not a desired property).


(UN N1)

No ignition in contact with a flame. (melts only)

 Relative self-ignition

(data waiving)

 Not required for low-melting solids (mp < 160°C)

 Contact with air or water

(data waiving)

 No pyrophoric properties expected, or release of flammable gas. (based on structure of major constituents and experience).


(data waiving)

 Unlikely for low melting solids (method not applicable).

 Explosive properties

(data waiving)

 No potential. (based on structure of major constituents) 

 Oxidising properties

(data waiving)

 No potential. (based on structure of major constituents) 

 Self-reactive properties

(data waiving)

 No potential. (based on structure of major constituents)

 Organic peroxide

(data waiving)

 No peroxide. (based on structure of major constituents)

Note that the numerical parameters may slightly vary from batch-to-batch, due to the UVCB nature of the substance.
