Overview of physico-chemical properties
| Parameter | Guideline(s) | Result | Comment |
| Freezing/Melting temperature | EC A.1 OECD 102 | 356°C | |
| Boiling temperature | Waived: The melting point is above 300°C. | Statement | |
| Density | EC A.3 OECD 109 | 2.34 at 23°C | |
| Particle size distribution (granulometry) | OECD 110 | Light microscopic examination revealed that the Potassium chlorate sample contained a significantly amount of fine powder and no fibres. | |
| ISO 2591-1 | This observation is confirmed by sieving the sample over a 100 µm sieve. The majority of the product (78.3 m/m %) appeared to be < 100µm . | ||
| ISO 3310-1 | The characteristics of the PSD of the fraction < 100 µm are: | ||
| Characteristics of the PSD | |||
| d10 [µm] 2.2 | |||
| d50 [µm] 17.3 | |||
| d90 [µm] 74 | |||
| Vapour pressure | Waived: The melting point is above 300°C. | Statement | |
| Partition coefficient | RA from sodium chlorate (CAS:7775 -09 -9) | log Kow < -2 | |
| Water solubility | EC A.6OECD 105 | 69.9 g/l | |
| Surface tension | Waived:based on the structure, surface activity is not expected and surface activity is not a desired property of the material. | Statement | |
| Flash-point | Waived: The study cannot be conducted because the substance is an inorganic solid. | Statement | |
| Auto flammability | |||
| EC A.16 | no relative self-ignition temperature | ||
| Flammability | EC A.10 | Not Flammable solid No pyrophoric, self-heating properties and no reaction with water are anticipated | |
| Explosive properties | EC A.14 / DSC screening | Waived based on screening DSC test, not explosive | Statement |
| Oxidizing properties | EC A.21 / screening test | Oxidizing, Cat.1 | |
| Stability in organic solvents and identity of relevant degradation products | Waived: The study does not need to be conducted if the substance is inorganic. | Statement | |
| Dissociation constant | Waived: Chlorate decomposes on acidification. | Statement | |
| Estimated pKa = -1 to -3 due to its strong acidity. | |||
| Viscosity | Waived: Potassium chlorate is a solid substance. Testing viscosity is therefore technically not feasible. | Statement |
For CLP there are additional data requirements that are not covered by REACH:
Gases under pressure | Pyrophoric
| Reaction with water | Self-reactive substances and mixtures | Corrosive against metals | organic peroxide |
Waiving, not a gas | Waiving, not a pyrophoric | Waiving, no reaction with water anticipated | Waiving, because the substance is a pure oxidizing solid | Data available, Conclusive but not sufficient for classification. | waiving, not an organic peroxide |
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).
