At the beginning of the 2019 New Year, OEKO-TEX (International Environmental Textile Association) routinely updated the STANDARD 100 standard. The cyclosiloxanes D4, D5, and D6, which have just been added to the REACH Substances of Very High Concern, are newly listed, and the specified limit is <01.%. From the current point of view, siloxane may be related to silicone, silicone oil finishing, silicone coating, silicone printing, softener-related three-proof finishing. From this limit, in fact, the requirements are not too high, the control index of 1000PPM should be relatively easy to achieve, but this will have a certain impact on the low-end applications of the silicone textile industry, and low boiler control of related products. Higher requirements were put forward, and a new technical direction was proposed for the development of the silicone industry. REACH, OEKO-TEX and the daily chemical industry will have higher and higher requirements for the control of residual amounts of silicone monomers in the future, and also put forward new requirements and technical improvement directions for the silicone downstream products industry.
