The particle size distribution was determined to be in the range of 150 micron to 25 micron.

Vapour pressure:

The study does not need to be conducted because the melting point is above 300°C.

Partition coefficient:

The octanol water partition coefficient of chemical 1,3,6-Naphthalenetrisulfonic acid, 7-(2-(2-((aminocarbonyl)amino)-4-((4-chloro-6-((4-(ethenylsulfonyl)phenyl)amino)-1,3,5-triazin-2-yl)amino)phenyl)d iazenyl)-, sodium salt was estimated to be 0.48.

Water solubility:

Based on the QSAR prediction done using the EPI Suite WATERNT Program (v1.01), the solubility of test substance in water was estimated to be 172.1 mg/l. Thus, based on this value, the substance was considered to be moderately soluble in water.

Surface tension:

In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. The chemical 1,3,6-Naphthalenetrisulfonic acid, 7-(2-(2-((aminocarbonyl)amino)-4-((4-chloro-6-((4-(ethenylsulfonyl)phenyl)amino)-1,3,5-triazin-2-yl)amino)phenyl)diazenyl)-, sodium salt is used as a dyestuff for textiles/paper industry. For this use, surface activity is not an important property. Hence this study was considered for waiver.

Flash point:

Based on available data from authoritative database,the flash point of chemical 1,3,6-Naphthalenetrisulfonic acid, 7-(2-(2-((aminocarbonyl)amino)-4-((4-chloro-6-((4-(ethenylsulfonyl)phenyl)amino)-1,3,5-triazin-2-yl)amino)phenyl)diazenyl)-, sodium salt (1:?). was determined to be greater than 200 degree C.

Auto flammability:

The chemical 1,3,6-Naphthalenetrisulfonic acid, 7-(2-(2-((aminocarbonyl)amino)-4-((4-chloro-6-((4-(ethenylsulfonyl)phenyl)amino)-1,3,5-triazin-2-yl)amino)phenyl)diazenyl)-, sodium salt (1:?).did not catch fire on being exposed to air at room temperature of 27°C and atmospheric pressure of 966 hPa. This indicates that 2-ethoxybenzoic acid is not auto-flammable.

Flammability:

The chemical 1,3,6-Naphthalenetrisulfonic acid, 7-(2-(2-((aminocarbonyl)amino)-4-((4-chloro-6-((4-(ethenylsulfonyl)phenyl)amino)-1,3,5-triazin-2-yl)amino)phenyl)diazenyl)-, sodium salt has an NFPA rating of 1 for Flamability and the flash point is greater than 200 degree C which is very high. As per the CLP regulation the chemical which has flash point >than 60 degree C was considered to be non-flammable. Thus, the chemical is unlikely to be "Flammable" under normal conditions of use, storage and transportation and hence this end point was considered for waiver & the chemical is classified as "Non Flammable".

Explosiveness:

The study does not need to be conducted because the substance contains chemical groups associated with explosive properties which include oxygen, but the calculated oxygen balance is less than - 200.

Oxidising properties:

In accordance with column 2 of Annex VII of the REACH regulation, the substance 7-[[2-[(aminocarbonyl)amino]-4-[[4-chloro-6-[[4-[vinylsulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]phenyl]azo]naphthalene-1,3,6-trisulphonic acid, sodium salt is incapable of reacting exothermically with combustible materials on the basis of the chemical structure. It is an organic substance containing oxygen and chlorine atom but these elements are not chemically bonded to nitrogen or oxygen. Thus, the chemcial is considered to be "Non-oxidising" for the purpose of chemical safety assessment.

Viscosity:

The study does not need to be conducted because the substance is a solid
