Description of key information
Based on an expert judgement, Acid Green 025 is considered to be not autoflammable.
Key value for chemical safety assessment
Additional information
The substance is produced and regularly used for many years in Europe, transported in various conditions and in various amounts. Evidence connected to the long experience in handling, use and transport of the substance confirms the non- self-ignition properties. Thus, the substance is expected to be an air-stable compound at room temperature over a prolonged period of time (days), without noticeable or undesirable reactions. Many dyes were tested and does not show low auto-ignition temperature. The substance decomposes before melting and it is not flammable. In conclusion, a potential for spontaneous ignition is not expected: the substance can be considered as a no-pyrophoric and no-self-heating solid because it is not liable to self-heat by reaction with air and without energy supply. In addition, the substance is very soluble in water at room temperature and forms a stable solution with water. No reactions with water or emission of flammable gases have ever been noted. Furthermore, for soluble dyes a reaction with water is not a desirable property from the use point of view. Therefore, the substance is considered to be not classified as a substance that in contact with water may react generating flammable gases.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
