Why D5 Cyclopentasiloxane doesn’t show in EU banned/restricted chemicals list?Posted by gunther on July 5, 2018 at 12:20 am
It doesn’t show as restricted here:
Where is it listed?

I don’t the restriction has come into effect yet.

First off the D5 isn’t restricted yet, it is banned in rinse of cosmetics (in concentrations above 0.1%) from January 31 2020.
Other reason you won’t find it in the cosmetics regulative yet is that the ban was passed through REACH, it can be found as entry 70 of annex XVII of Reach.
it may be placed on annex III at a later date, but I am not certain if that is currently in the works.

So the 0.1% limit applies only to rinse-off products?
Any updates if it got restricted in leave-on products too?
They were supposed to file a dossier by April 2018
Furthermore, the European commission has requested The European Chemical Agency (ECHA) to prepare a new dossier regarding restriction of D4/D5 in leave-on consumer product. The scope of this restriction will include products containing D4/D5 concentration of more than 0.1%. It is expected that ECHA will publish the final dossier in April 2018.
MemberJuly 6, 2018 at 4:04 pmYes, the limits as currently set applies only to Rinse-off products.The ECHA did file a registration of intention to restrict usage in leave-on products with a deadline set to April 2018 (Request) but later adding D6 to both the rinse-off and leave-on restriction in their registration. (Registry of Restriction Intentions)The deadline was originally set to April 2018 but postponed to January 2019 due to the addition of D6 to the dossier. (Update to the request)Recently, the call for evidence for RAC (A chance for stakeholders to submit study data relevant to the dossier to the Committee for Risk Assessment) had its deadline. (Previous Calls for Evidence).

Any chance they may not get banned in leave-on products?
Being leave-on they won’t end up flushed down the drain, they’ll first evaporate
Unless they can prove that it condenses back in rainfall and ends up in rivers and oceans before being biodegraded.
I wonder where does it go?
Does it float high up in the atmosphere?
Does it sink just above the ground?
Where does it go?, reminds me of Jack Black and Ben Stiller ‘Envy’ movie.
MemberJuly 7, 2018 at 5:57 pmIn principle, yes, it might remain allowed in Leave-on products.But honestly I don’t know, sometimes the regulators are unpredictable. If RAC concludes it to be near negligible in toxicity it might depend on the opinion of the committee that assesses social-economic impact. But that won’t be until after RAC are done with their analysis.Once it reaches the water it will bioaccumulate in marine animals (Salmon I believe was the main reason) which we might eat and ingest (It was observed to accumulate around rat livers in a toxicity study of D5). Which was the reason for the D5 restriction (read: ban).What is worth remembering is the impurities in Dimethicone - the 0.1% is basically there as a safety margin for impurities in other silicones.Maybe you can enlighten me on something.- I know D5 (and D4) are considered volatile, but they have a low vapour pressure (something along 30 Pa) how can they possibly be considered volatile and expected to evaporate off the skin?

And I just found that for D4, D5 and D6 for leave on in Cosmetics.
Additionally, D4, D5 and D6 will not be placed on the market and made available on the market in leave-on cosmetic products at a concentration of ≥ 0.1% after 3 years from the entry into force of the Regulation.
The restrictions on the use of D4, D5 and D6 in leave-on products will apply 3 years after the entry into force of the regulation.
But if Regulation: 4th quarter of 2023. is already on does that apply already for D5 in leave on cosmetic or not? How do you read that?
