Beginning in June, Singapore will prohibit the use of short-chain chlorinated paraffins in metalworking fluids and other products, according to the countrys National Environmental Agency.
Short-chain chlorinated paraffins are chlorinated alkanes with carbon chain lengths ranging from 10 to 13 with varying degrees of chlorination. They are typically used in metalworking fluids as extreme pressure agents, particularly in drawing, forming and removal operations.
Under Singapores new regulation, production, import, export and use of products containing SCCPs will not be allowed, in accordance with the United Nations Stockholm Convention on Persistent Organic Pollutants. The convention suggested alternatives such as oleochemicals and alkyl phosphate esters, a phosphorus-based compound.
SCCPs will still be permitted in formulations of lubricant additives for automobile engines, electric generators, wind power facilities, oil and gas exploration drilling equipment, and refining equipment used in the production of diesel oils.
Singapores National Environment Agency plans to report the new regulation in official framework by the end of this year. Importers, manufacturers and distributors will have 6 months from the date of announcement to comply.
The Stockholm Convention on Persistent Organic Pollutants is a global treaty to protect human health and the environment from POPs. POPs are chemicals that can remain in the environment for a long time and spread and accumulate in the fatty tissues of humans and wildlife.
