— Read the siloxane test in one piece –
1 What is siloxane? Siloxane
is a class of silicone compounds containing Si-O-Si bonds, which are
widely used in rubber, detergent, polishing, adhesive, sealants and
other fields. Due to the environmental and health risks of certain
siloxanes, siloxanes have been regulated in many countries and regions
around the world.
2 How do relevant countries and regions control siloxane? EU REACH regulation: D4,
D5, D6, ocmethyltrisiloxane, demethyltetrasiloxane,
1,1,1,3,5,5,5,5-seven methyl-3-[(trimethylsilane)oxygen] trisiloxane is
classified as a substance of very concern (SVHC) and restricts its use
in some products. EU Cosmetics Regulation: D4
and D5 are prohibited for flushing cosmetics, with a limit of 0.1%. D6
is not explicitly restricted at this time, but a risk assessment is
required due to SVHC status. Stockholm
Convention: Due to the difficulty of degradation in the environment of
D4, D5 and D6, they are proposed to be included in the Stockholm
Convention POPs list. China:
China has not yet clearly defined the restrictions on D4, D5, and D6,
but the relevant industry standards are gradually improving.
3 Importance of Siloxane Testing Compliance requirements : With the increasing emphasis on environmental and health protection in the world national
regulations restrict and control siloxanes more and more strictly.
Through the siloxane test, enterprises can ensure that the product meets
the relevant regulatory requirements and avoids legal risks and
economic losses due to violations. Environmental protection:
Some siloxanes are persistent, bioaccumulative and toxic (PBT), which
may cause long-term harmful effects on aquatic environments, soil and
other ecosystems. Effectively control the residue of siloxane, help
reduce environmental pollution, protect the ecological environment. 3 quality control: In the application of electronic products and other fields,
low molecular weight siloxane may affect the performance and quality of
the product, such as leading to electrical contact failure, optics
blurry fogging and other issues. By testing the siloxane content,
enterprises can optimize the production process, improve product
quality, enhance market competitiveness, and help enterprises establish a
good brand image.
4 How companies respond Enterprises
should deeply understand and comply with the EU REACH, cosmetics
regulations, the Stockholm Convention and Chinese industry standards,
evaluate the compliance of siloxane content in products, and ensure that
the siloxane content in the production process meets environmental and
health standards. Develop low-siloxane alternatives to reduce
environmental health risks through technological innovation. Continue to
pay attention to regulatory updates, adjust strategies in a timely
manner, reduce market risks, and promote sustainable development. Meixin
Testing can help companies investigate the presence of siloxane
substances in electrical and electronic products, components and raw
materials, provide professional solutions to avoid trade risks, and
promote sustainable development.
– U.S. News test recommendations –
With
the continuous updating and improvement of siloxane regulatory
regulations, enterprises need to pay close attention to relevant
developments, timely adjust test methods and production processes,
strengthen the detection and management of siloxane components, ensure
that products meet international and domestic regulatory requirements,
and avoid market risks due to violations.
