Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 266-046-0 | CAS number: 65997-17-3 This category encompasses the various chemical substances manufactured in the production of inorganic glasses. For purposes of this category, 'glass' is defined as an amorfous, inorganic, transparent, translucent or opaque material traditionally formed by fusion of sources of silica with a flux, such as an alkali-metal carbonate, boron oxide, etc. and a stabilizer, into a mass which is cooled to a rigid condition without crystallization in the case of transparent or liquid-phase separated glass or with controlled crystallization in the case of glass-ceramics. The category consists of the various chemical substances, other than by-products or impurities, which are formed during the production of various glasses and concurrently incorporated into a glass mixture. All glasses contain one or more of these substances, but few, if any, contain all of them. The elements listed below are principally present as components of oxide systems but some may also be present as halides or chalcogenides, in multiple oxidation states, or in more complex compounds. Trace amounts of other oxides or chemical compounds may be present. Oxides of the first seven elements listed* comprise more than 95 percent, by weight, of the glass produced. @Aluminium*@Lead@Boron*@Lithium@Calcium*@Manganese@Magnesium*@Molybdenum@Potassium*@Neodymium@Silicon*@Nickel@Sodium*@Niobium@Antimony@Nitrogen@Arsenic@Phosphorus@Barium@Praseodymium@Bismuth@Rubidium@Cadmium@Selenium@Carbon@Silver@Cerium@Strontium@Cesium@Sulfur@Chromium@Tellurium@Cobalt@Tin@Copper@Titanium@Germanium@Tungsten@Gold@Uranium@Holmium@Vanadium@Iron@Zinc@Lanthanum@Zirconium

Description of key information
The test product was an MMVF note Q fibre (i.e. Roxul 1000 fibres). Sample No FI990571 -00 was tested for acute toxic effects on juvenile zebra fish (Danio rerio) according to the OECD guideline for Testing of Chemicals No 203 " Fish Acute Toxicity Test". No mortality or behavioural effects were observed during the test. The LC10 and LC50 values are thus indicated as > 1.60 mg "Roxul 1000 fibres: sample No FI990571 -00" (>1000 mg/L).
Key value for chemical safety assessment

Additional information
Man-made vitreous fibres (MMVF) note Q fibres and E-glass micro fibre have similar physical and chemical properties (most importantly both are highly insoluble and inert inorganic solid fibres). It is thus evaluated that results of a guideline GLP study, which was carried out using MMVF note Q fibres as the test substance is also applicable here to E-glass microfibre. Below evaluation was made using the results of MMVF note Q fibres study.
No mortality or behavioural effects were observed during the test. The LC10 and LC50 values are thus indicated as > 1.60 mg "Roxul 1000 fibres: sample No FI990571 -00" (>1000 mg/L).
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.
