Description of key information
Additional information
Appearance/physical state/colour
On the basis of physical observation and using the sense of smell l-Glutamic acid, N-coco acyl derivs., monosodium salts was found to be an organic, colourless solid having pungent odour.
Melting point/freezing point
The melting point of Sodium Cocoyl glutamate was found to be 212 °C at 970hPa by capillary Method
Boiling point
The boiling point of l-Glutamic acid, N-coco acyl derivs., monosodium salts was obtained to be 220 degC at 970 hpa.
Density
The bulk density of l-Glutamic acid, N-coco acyl derivs., monosodium salts by the mass by volume method was found to be 0.723 g/cm3 at room temperature of 37 °C.
Particle size distribution (Granulometry)
The particle size distribution (granulometry) of l-Glutamic acid, N-coco acyl derivs., monosodium salts by the sieve analysis method was found to be in the range of 75 micrometer to 500 micrometer. Majority of the particles were found to be in the size range of 500 micrometer.
Partition coefficient
The experimental value of octanol water partition co-efficient (log Pow) of Sodium Cocoyl glutamate by Shake flask method was found to be 0.597 at temperature 37 degC and pH of 5.45.
Water solubility
The experimental value of the water solubility of Sodium Cocoyl glutamate was found to be 87800 mg/L at temperature of 37deg C indicating that that the substance is highly soluble in water.
Solubility in organic solvents / fat solubility
The experimental value of solubility of Sodium Cocoyl glutamate in Methanol at temperature of 37deg C was found to be 3600 mg/L indicating that Sodium Cocoyl glutamate is soluble in Methanol. Similarly, the experimental value of solubility of Sodium Cocoyl glutamate in Petroleum Ether at temperature of 37 deg C was found to be 88 mg/L indicating that the substance is slightly soluble in Petroleum Ether.
Surface tension
In accordance with Column 2 adaptation statement of REACH Annex VII, information requirement 7.6, this end point was considered for waiver since surface activity was not a desired property of Sodium Cocoyl glutamate.
Flash point
The experimental value of flash point for Sodium Cocoyl glutamate by the open cup method was found to be 145 deg C at 970 hPa atmospheric pressure. Thus indicating that the target substance is not flammable in nature.
Auto flammability
Sodium Cocoyl glutamate did not catch fire on being exposed to air at room temperature of 37 deg C and atmospheric pressure of 970 hPa. This indicates that Sodium Cocoyl glutamate is not auto-flammable.
Flammability
From the experimental values of flammability, Sodium Cocoyl glutamateignited when the flame of Bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that Sodium Cocoyl glutamateis flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, Sodium Cocoyl glutamatewas considered non-flammable for chemical safety assessment.
Explosiveness
In accordance with column 2 of Annex VII, this end point was considered for waiver since there are no chemical groups associated with explosive properties present in the molecule of Sodium Cocoyl glutamate.
Oxidising properties
2-amino-4,6-dinitrophenoxide was found to be non oxidising
Stability in organic solvents and identity of relevant degradation products
2-amino-4,6-dinitrophenoxide was found to be stable in organic solvent dichloro methane and no degradation products were formed after 24 hours as evident from the GC-MS chromatogram obtained at 0 hours and that obtained after 24 hours.
pH
1% by volume solution of Sodium Cocoyl glutamate was found to exhibit a pH of 5.39 at 25 deg C.
Dissociation constant
The experimental pKa value for Sodium Cocoyl glutamate was found to be 0.28 x 10-9, 0.28 x 10-9, 0.29 x 10-9. The average pKa value was found to be 0 at 23 deg C indicating that the chemical has no dissociation properties.
Viscosity
This end point was considered for waiver since viscosity is an inherent property of a liquid that offers resistance to its flow and Sodium Cocoyl glutamate is a solid substance and hence this testing was considered scientifically unjustified for Sodium Cocoyl glutamate.
