- Endpoint:
- pyrophoric solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

- Executive summary:
In accordance with section 1 of REACH Annex XI, the study does not need to be conducted. In this compound, the iron ion is already in its maximum oxidation stage of +III. Further oxidation is not possible. Therefore, this substance will now react with oxygen or air. The substance is not flammable.
- Endpoint:
- self-heating substances / mixtures

Description of key information
a) Flammability
In this compound, the iron ion is already in its maximum oxidation stage of +III. Further oxidation is not possible. Therefore, this substance will now react with oxygen or air. The substance is not flammable.
b) Self-heating properties
A study on self-heating behaviour of the substance does not need to be conducted. In this compound, the Iron ion is already in its maximum oxidation stage of +III. Further oxidation is not possible. Therefore, this substance will not react with oxygen or air, and self-heating of the substance up to 400 °C is excluded.
c) Pyrophoric properties
The study on pyrophoric properties does not need to be conducted due to experience in production and handling, the substance is known to be stable at room temperature.
d) Flammability in contact with water
A study concerning the contact with water does not need to be conducted as the substance is an inert oxide which does not react with water. Flammable gases are not formed in contact with water.
e) Organic peroxide
The substance does not need to be assessed for organic peroxide properties, as based on its chemical structure, the substance is not an organic peroxide.
f) Self-reacting properties
A study concerning self-reacting properties does not need to be conducted, as there are no chemical groups present in the molecule associated with explosive or self-reactive properties; examples of such groups are given in Tables A6.1 and A6.2 in Appendix 6 of the UN RTDG, Manual of Tests and Criteria.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Justification for classification or non-classification
Iron hydroxide oxide yellow is not flammable, it has no pyrophoric properties, no flammability in contact with water, is not a self-heating and a self-reactive substance, is not an organic peroxide; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008) is required.
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).
