21 November 2015 Prof. Dr. H.Z. Warning! Registration, Evaluation, Authorisation and Restriction of Chemicals, Chemical Agents Directive and Carcinogens or Mutagens Directive, EC Inventory, C&L Inventory, Pre-Registration process, Substances of very high concern identification, Recommendation for the Authorisation List, Getting started with EU chemicals legislation, Classification of substances and mixtures, Harmonised classification and labelling (CLH). The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. Substances for which classification and labelling data have been notified to ECHA by manufacturers or importers. The REACH registered substance data and the C&L Inventory portal will be upgraded from the 9th November. the electronic edition of the Official Journal of the European Union. The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. For example, Or80 indicates that the mineral is composed of 80 percent KAlSi3O8 and 20 [i.e., 100 − 80] percent NaAlSi3O8.) REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. Feldspat was introduced in the 18th century as a more specific term, referring perhaps to its common occurrence in rocks found in fields (Urban Brückmann, 1783). The Prior Informed Consent Regulation administers the import and export of certain hazardous chemicals and places obligations on companies who wish to export these chemicals to non-EU countries. Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA. The molecular structure is based on structures generated from information available in ECHA’s databases. The CLP Regulation ensures that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union through classification and labelling of chemicals. The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format. This section is based on three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. The date of the last update corresponds to the publication date of the InfoCard and not necessarily to the date in which the update occurred in the source data. Spat had long been used as the word for "a rock easily cleaved into flakes". Experimentally, K-feldspar and other feldspar minerals are known to be good ice-nucleating agents, which play a significant role in atmospheric science. Feldspar The name feldspar derives from the German Feldspat, a compound of the words Feld (field) and Spat (flake). disodium tetraborate EC no. Description. conchoidal, uneven .

Vitreous. The term silicate stands for a combination of silicon and oxygen. This site is not fully supported in Internet Explorer 7 (and earlier versions). Although plagioclase grains in some rocks are essentially homogeneous, those in many rocks are zoned—i.e., different parts of individual grains have different Ab and An contents. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. As another important difference between quartz and feldspar we can say that the repeating unit of quartz is SiO 4 while the repeating unit of feldspar is KAlSi 3 O 8 – NaAlSi 3 O 8 – CaAl 2 Si 2 O 8 .
