The status of Flat Soda Lime Silicate Glass and its raw materials under REACH

This document aims to clarify the status of the Soda Lime Silicate (SLS) glass used for the manufacture of flat glass products1 and its raw materials in relation to the requirements of REACH2 and demonstrate that flat soda-lime-silicate (FSLS) glass meets the requirement for exemption of registration and that its raw materials must be considered as intermediates. In this regard, the following will be provided in order to fulfil the requirement of Article 363:

• the chemical identity of the soda lime silicate glass used in flat glass products;
• a description of the relevant chemical reactions taking place in the synthesis of the new substance i.e. the soda lime silicate (SLS) glass;
• a description of the technical role in the process for which the intermediates are used in the manufacturing of the new substance and the functional properties that they bring to the new substance;
• demonstration that the SLS glass manufactured from the intermediate is exempted from registration under REACH.
