Endpoint summary
Administrative data
Description of key information
Additional information
Appearance/physical state/colour
The sample is a powder at 22°C and atmospheric pressure.
Melting point/freezing point
The melting point has been determined to 135 ºC.
Boiling point
The boiling point has been determined to 177 ºC.
Density
The relative density is determined to 930 at 20 °C.
Particle size distribution (Granulometry)
Not applicable. According to ECHA’s Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance: “The study does not need to be conducted if the substance is marketed or used in a non solid or non granular form”.
Vapour pressure
In order to read across with a “worst case scenario” substance the vapour pressure measured on Coco dipropylene triamine (C8-18dipropylene triamine; CAS#: 91771-18-5), a smaller molecule which could occur in low levels in the to be registered substance, was read acrossed.
Partition coefficient
Read across is based on Oleyl tripropylene tetramine (C18tripropylene tetramine, CAS# 67228-83-5) and Coco dipropylene triamine, (C8-18dipropylene triamine; CAS#: 91771-18-5). Given that Oleyl tripropylene tetramine (C18tripropylene tetramine) consists of various constituents, among others Oleyl dipropylene triamine (C18dipropylene triamine) and acetate salts increase the water solubility, the partition coefficitent of Oleyl tripropylene tetramine (C18tripropylene tetramine, CAS# 67228-83-5) can be considered as the worst case scenario. The partition coefficient of both test substances is -0.3 at 25.6 °C at pH 6.
Water solubility
According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", the critical micelle concentration (CMC) can be considered as the solubility limit. Given that the watersolubility of the acetate salt is higher than the watersolubility of the pure N-(3-aminopropyl)-N'-[3-(C16-18 (evennumbered), C18 unsaturated alkyl amino)propyl]propane-1,3-diamine the read across is considered as “the worst case scenario”.
Surface tension
The CMC is determined to 40 mg/L at pH 7. Also, the surface tension at 0,5 g/L and pH 7 has been determined to 30 mN/m. Given that the water solubility of the acetate salt is higher than the watersolubility of the amine the read across is considered as “the worst case scenario”.
Flash point
According to Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, “The flash point is only relevant to liquids and low melting point solids. Therefore, for many substances it is not required.” Therefore, the flammability has been determined instead.
Auto flammability
According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance": For solids, the test method does not work well for substances with a melting point of <160°C and testing is not required.
Flammability
In the screening test Tallow dipropylene triamine(C12-18diproplyene triamine)was tested. The gas flame was applied for 2 minutes to one end of the substance train, but no ignition and no propagation of combustion occurred. Only melting took place where the substance was exposed to the flame. Therefore the substance is not considered as highly flammable and no further testing is required. Given that the acetate form is considered to have a higher flammability temperature the read across can be considered as a worst case scenario.
Flammability in contact with water
The chemical structure ofN-(3-aminopropyl)-N'-[3-(C16-18 (evennumbered), C18 unsaturated alkyl amino)propyl]propane-1,3-diamine acetatedoes not contain chemical groups, capable of causing the development of a dangerous amount of (flammable) gas (e.g.hydrogen), when in contact with damp air or water. In addition, from experience in handling and use no flammability in contact in water is expected, as the substance is marketed in aqueous solutions. Therefore, the test substance is not considered highly flammable in contact with water.
Flammability (pyrophoric properties)
From the structural formula of N-(3-aminopropyl)-N'-[3-(C16-18 (evennumbered), C18 unsaturated alkyl amino)propyl]propane-1,3-diamine acetate it can be concluded that the substance is not pyrophoric N-(3-aminopropyl)-N'-[3-(C16-18 (evennumbered), C18 unsaturated alkyl amino)propyl]propane-1,3-diamine acetate does not contain any chemical group that might lead to spontaneous ignition shortly after coming into contact with air at room temperature. In addition, from experience in handling and use no ignition in contact with air is expected.
Explosiveness
According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", “For the majority of substances, explosivity is not a concern and testing can be waived based on a consideration of the structure.” In chapter R.7a a table (Table R.7.1-28) of chemical groups associated with explosive properties is given. The registered substance does not contain any of these chemical groups. Therefore, based on structure, explosive properties are not expected.
Oxidising properties
According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", “For the majority of substances, oxidising properties are not a concern and testing can be waived based on a consideration of the structure.” In chapter R.7a a table (Table R.7.1-29) of chemical groups associated with oxidising properties is given. N-(3-aminopropyl)-N'-[3-(C16-18 (evennumbered), C18 unsaturated alkyl amino)propyl]propane-1,3-diamine acetate does not contain any of these chemical groups. Therefore, based on structure, oxidizing properties are not expected.
Additional physico-chemical information
As indicated before, the addition of acetate groups to the polyamines increase their water solubility. The polyamines when dissolved in water take up positive charged hydrogens to become cationic substances. As a consequence the water solution becomes alkaline. With the addition of acetic acid, the cationic substance is already present in the Polyamine acetates, linked to the negatively charged acetate ions. The polyamine acetate substance is therefore more easily soluble in water, which can only be explained from the dissociation of the acetate ions, as without that, uncharged molecules would not be easier soluble. Following the dissociation of the polyamine acetate salts, there is no principle difference after absorption of the polyamine structures following exposure as polyamines as such or as polyamine acetate.
