Description of key information
Additional information
Terracess P, an inorganic substance, is a fine, fluffy, white powder. No melting or decomposition below 400°C. Relative density is 3.42. The particle size distribution is as follows: 90% < 14.79 µm; 50% < 7.792 µm; 10% < 2.397 µm.
The vapour pressure was determined by the Static method to be 0.31 Pa. Insoluble in water and n-octanol. Log Kow could not be estimated or determined by experiment. Not surface active. Not flammable by ignition. No self-ignition. Not flammable in contact with water or in contact with air. Not explosive.
The substance does not contain chemical groups indicating self-reactive properties, such as aminonitriles, haloanilines, organic salts of oxidizing acids, sulphonyl halides, sulphonyl cyanides, sulphonyl hydrazides, phosphites, strained rings, olefins or cyanates. Therefore, based on structural features it is concluded that the substance is not self-reactive.
No self-ignition in the EC A.16 test and no groups that will be react exothermically with oxygen in the air. Terracess P is concluded to be not self-heating.
Not oxidising according to EC A.17. Terracess P is an inorganic substance containing oxygen in the form of oxide. An oxide is an anion of oxygen in the oxidation state -2. This will not sustain a combustion.From this it is concluded that Terracess Po does not need to be classified and labelled as oxidising according to EC 1272/2008.
Terracess P is not corrosive or irritating to skin or eyes. Insoluble in water. Because of the lack of significant basic or acid groups, no corrosion is to be expected. No halogens in the molecules. Terracess P is not expected to be corrosive to metals.
Based on the know physical and chemical properties, Terracess P does not need to be classified as a hazardous substance according to Directive 67/548/EEC and the CLP regulation EC 1272/2008.
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.
