is the silicon in daily chemicals harmful? -safety discussion 2-cosmetic silicone oil manufacturer

in january 2018, the european union gazette published the european commission’s amendment no. 2018/35, which formally revised annex xvii of the reach regulation to stipulate the use of octamethylcyclotetrasiloxane (d4) and decamethylcyclopentasiloxane in rinse-off cosmetics. the content of alkane (d5) must be less than 0.1%. this revision of the regulations has ended the 10-year dispute over the use of d4 and d5. at the same time, the establishment of a concentration limit of 0.1% can effectively stop the addition of d4 and d5. ” “no d4, d5” will become the standard for european rinse-off cosmetics. it can be seen that although there is no clear research data to prove the harm of d4 and d5, we cannot deny their potential safety hazards.
