Endpoint summary
Administrative data
Description of key information
Appearance:
On the basis of physical observation,the chemical Aluminium tristearate was observed to be white colored powder in appearance.
Melting point:
The melting point determination of Aluminium tristearate (CAS No. 637-12-7) was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and Mean Melting Point was determined to be 179.5°C at 976.4hPa.
Boiling point:
The boiling point determination of Aluminium tristearate (CAS No. 637-12-7) was done following OECD Guideline 103 and according to the method of Siwoloboff. the test item melts at 179.5 °C, but forms viscous liquid at around 250, no string of bubbles observed, inferring boiling point was determined to be greater than 250°C at 976.5 hPa.
Density:
The density of substance Aluminium tristearate (CAS No. 637-12-7)was determined following OECD Guideline 109 and according to the Adapted from ASTM D854-02 using glass pyknometer .The mean density of test item is was found to be1.066 g/cm³at 20°C and 975.85 hP
Particle Size Distribution:
The particle size distribution of test item Aluminium tristearate (CAS No. 637-12-7 ) was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 150 micron to 53 micron.
Vapour Pressure:
Data from authoritative databases suggests that the estimated vapour pressure ofAluminum tristearate at 25 deg C was1.08E-018 mm Hg =1.44E-016 Pa.
Partition Coefficient:
Data from authoritative and modeling databases suggests that the estimated logPow ofAluminum tristearate was 22.69.Based on this value,Aluminum stearate can be considered to be highly hydrophobic in nature.
Water Solubility:
The water solubility determination of test item Aluminium tristearate (CAS No. 637-12-7) was done as per the OECD guideline 105 and by spectrophotometric analytical method as per OECD 101. The solubility of Aluminium tristearate [CAS: 637-12 -7] in water was determined to be Insoluble in water at 30°C.
WSKOW v1.42 was used to estimate the water solubility of the Aluminum stearate.
The estimated water solubility of Aluminum stearate at 25 deg C was 9.386E-020 mg/l.
Data from various handbooks and authoritative databases suggests that Aluminum stearate was practically insoluble in water.
Hence, on the basis of the estimated value and experimental results, Aluminum stearate can be considered to be highly insoluble in water.
Surface tension:
From predicted ACD lab data, the surface tension of aluminum trioctadecanoate (637-12-7) was predicted to be 33.4 ± 3.0 dyne/cm.
Autoflammability:
The autoflammability of aluminum trioctadecanoate (637-12-7) from authoritative database was determined to be 375 degree C at Minimum ignition energy as <1 mJ.
Flammability:
Aluminum trioctadecanoate does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that aluminum trioctadecanoate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus aluminum trioctadecanoate was considered non-flammable for chemical safety assessment.
Explosiveness:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties
Oxidising properties:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
pH:
pH of 1% w/v aqueous solution of the aluminum trioctadecanoate (CAS No.637-12-7) is 5.34 at 28 °C. Thus, 1% solution can be considered to be near acidic in pH.
Viscosity:
The study does not need to be conducted because the substance is a solid.
Additional information
Appearance:
On the basis of physical observation,the chemical Aluminium tristearate was observed to be white colored powder in appearance.
Other supporting studies from reliable sources such as authoritative database,handbooks and from review article also suggests that the chemical Aluminium tristearate was observed to be white colored powder in appearance.
Melting point:
The melting point determination of Aluminium tristearate (CAS No. 637-12-7) was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and Mean Melting Point was determined to be 179.5°C at 976.4hPa.
Other supporting studies from various reliable sources such as authoritative database and handbooks also suggests that the metling point of chemical Aluminium tristearate was determined to be in the range of 105 degree C to 120 degree C.
As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of melting point temperature as 179.5 degree C thus considered as key study for the chemical safety assessment
