Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2019
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Justification for type of information:
- In house data, viscosity is measured and reported for a large range of different temperature values.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The sample is heated in a heating oven to around 120 °C and subsequently loaded into a preheated rheometer (Malvern, Kinexus lab+) equipped with a cup-bob geometry (Malvern, Cup C25 cylinder DIN standard SS – Bob C25 cylinder DIN standard). The program is started and the sample is conditioned for 5 min. before measurement starts. The program is set to run from 120°C to 40°C with a shear rate of 10 s-1 and a cooling rate of 1 °C/min. The program collects data points each 20 seconds throughout the run. Log to the viscosity in Pa·s is then plotted as a function of temperature in °C, giving the viscosity curve. (see attached report).
- GLP compliance:
- not specified
- Type of method:
- other: Not specified.
- Specific details on test material used for the study:
- Not specified
- Key result
- Temp.:
- 40°C
- Parameter:
- other: Shear viscosity
- Value:
- > 0.01 - < 0.1
- Remarks on result:
- other: Pa S
- Conclusions:
- Shear viscosity of the registered substance " Stearic acid, monoester with propane-1,2-diol " is as read from the viscosity curve between 0.01 and 0.1 PaS at 40°C.
- Executive summary:
Viscosity of the substance has been studied at different temperatures ranging from ca. 40 to 120°C. Shear viscoty of the registered substance " Stearic acid, monoester with propane-1,2-diol " is as read from the viscosity curve between 0.01 and 0.1 PaS at 40°C.
