Chemcial formulations - siloxanes
Parameters (quantitative): octamethylcyclotetrasiloxanes (D4) (CAS 556-67-2) [mg/kg], decamethylcyclopentasiloxane (D5) (CAS 541-02-6) [mg/kg], dodecamethylcyclohexasiloxane (D6) (CAS 540-97-6) [mg/kg] Article Number: 2011539 Description: Legal limit values for toxic, carcinogenic, mutagenic and other such substances generally apply only to finished end products, e.g. textiles, footwear, plastics, etc. However, raw materials, auxiliary materials and additives used during the industrial processing of these products have not, to date, been tested for such prohibited substances at all, even though it is precisely through their use that such substances are introduced into the end products. If only ‘clean’ chemicals are used during the manufacturing process, manufacturers can take a major step towards ensuring compliance with the legal requirements for end products at an early stage. Through proficiency tests on industrial chemicals such as dyeing post-treatment agents, water-repellent agents and auxiliary materials in the tanning industry, the DRRR supports laboratories and manufacturers in the analysis of such formulations. Testing for siloxanes e.g. possible with ISO 23649 Category: chemical-physical testing Environmental analytics chemicals and chemical formulations Accreditation: This proficiency test is not included in the scope of the accreditation.
