Safety Data Sheet

Getting an SDS for 4-(1,1,3,3-tetramethylbuty…

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 4-(1,1,3,3-tetramethyl… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements

4-(1,1,3,3-tetramethylbutyl)ph… precautionary statements

CLP Annex VI assigns 12 precautionary statements to 4-(1,1,3,3-tetramethylbuty…. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

05 · Names in the regulation

4-(1,1,3,3-tetramethylbutyl)ph… name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.
