Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
This substance is being registered at less than 100 tonnes per annum (Annex VIII).
Phototransformation
In accordance with Annex X of the Regulation (EC) No 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), information regarding the photo-transformation in air, as well as in water and soil, is not mandatory.
Stability
According to the REACH Regulation a hydrolysis study does not need to be conducted as the substance is readily biodegradable. Therefore, the requirement to conduct a hydrolysis study is waived and no further testing is required.
Biodegradability
A reliable study (Klimisch 1) to determine the ready biodegradability for the test substance measured 63% at the end of the test (Day 28) and may be considered readily biodegradable. The 10-day window pass level can be waived as the test item can be classed as a substance of unknown or variable composition.
Bioaccumulation
In accordance with Annex IX information regarding the aquatic bioaccumulation is not mandatory for substances manufactured or imported in quantities of less than 100 tonnes per annum. For information, the Log Pow was experimentally determined to be > 6.2. However, in accordance with Chapter R.11 ECHA Guidance even though the Log Pow value is > 4.5 there is a decreasing relationship between log Pow and bioaccumulation potential at > Log Kow of 6, due in part to experimental errors in the determination of BCF values for very hydrophobic substances. In addition, the test substance may be considered readily biodegradable which may lead to relatively low concentrations of the test substance in the aquatic environment and thus to low concentrations in aquatic organisms.
Transport and Distribution
There are no laboratory studies available for the estimation of adsorption/desorption of the test substance. The adsorption of glycerine monostearate propoxylate was estimated using the QSAR model EpiSuite with a Log Koc of between 3.12 and 7.56 and corresponding Koc of between 1,330 and 363,107,805 l/kg.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
