- D4 (i-octamethylclotetrasilosilosilosiloxine) I-D4

- D5 (ye-chalmareethyclopentasiloxiloxiloxiloxane) I-D5

-D6 (DODDCAMTHLCCloheXaxane) I-D6

UKUHLAZIYELWA KWE-D4 NO-D5 kwiimveliso zononophelo lobuqu:

I-octthylclostilosilosilosiloxiloxine (D4) kunye ne-ceremethycyclopentasiloxiloxiloxiloxiloxane (D5) ukongezwa kuyoFikelela uluhlu lwezinto ezithintelweyo ze-Annex xvii(Nge-70) ngeUmmisi weChrisory (EU) 2018/35kwiNge-10 Jan 2018. I-D4 kwaye i-D5 ayiyi kufakwa kwintengiso ekuhlaleni iimveliso ze-cosmetic zilingana okanye ngaphezulu kwe0.I-1%ngobunzima bento, emvaNge-31 kaJanuwari 2020.

Kutheni i-D4 ne-D5 ithintelwe?

I-D4 kunye ne-D5 ziziseko ze-cycloxaxanes ikakhulu zisetyenziswa njengabasebenzi kwimveliso ye-silicone polymer ye-polymer. Banokusetyenziswa ngokuthe ngqo kwiimveliso zononophelo lomntu. I-D4 ichongiwe njengeIqhubekeka, i-biacucucucucucucucucucucucucucucucucucucucubumbeki (PBT) kwaye iqhubekeke kakhulu kakhulu (i-vpvvb). I-D5 ichongiwe njengento ye-vpvbb.

Ngenxa yenkxalabo ye-D4 kwaye i-D5 inokubanakho ukuqokelela kwindalo kwaye ibangele ukuba kungalindelekanga kwaye kungabi nakuphikiswa kwixesha elide, uvavanyo lomngcipheko (i-ECHA) kunye nezoqoqoshoUVAVANYO

Ukusetyenziswa okuthintelweyo kwe-D4 kunye ne-D5 kwezinye iimveliso?

Ukuza kuthi ga ngoku i-D4 kwaye i-D5 ayikhawulelwanga kwezinye iimveliso. I-ECO isebenza kwisicelo esongezelelweyo sokuthintela i-D4 kunye ne-D5 ngaphakathiShiya iimveliso zononophelo lomntukunye nezinyeImveliso yabathengi / yeemveliso zobungcali. Isicelo siya kungeniswa ukuze sivunyweEpreli 2018. Umzi mveliso uvakalise inkcaso eqinileyo kolu thintelo olongezelelweyo.

NgaphakathiNgomhla ka-Matshi 2018, I-ECC iphakamise ukongeza i-D4 kunye ne-D5 kuluhlu lwe-SVHC.

Isalathiso:

• Ummisi weChrisory (EU) 2018/35
• Ikomiti yovavanyo lomngcipheko (i-RAC) ivuma isindululo sokuthintela i-D4 kunye ne-D5 kwi
• Ukuhlanjwa kwe-cosmetics
• Iinjongo zokuthintelwa kwe-D4 kunye ne-D5 kwezinye iimveliso
• I-Scades Yurophu-eyongeziweyo yokufikelela kwizithintelo ze-D4 kwaye i-D5 ingaphambi nangaphambi kokuba iphinde ihlale i-Juni-kaJuni7

Yintoni izilumko?

I-Silicones ineemveliso ezizodwa ezisetyenziswa kumakhulu ezicelo apho kufuneka khona ukusebenza kwabo okhethekileyo. Zisetyenziswa njengabahambi, ziyaqhama, kwaye zineempawu ezibalaseleyo / zokuchasana / ubunyani bezinto ezininzi. Zisetyenziselwa, umzekelo, kubuchwepheshe kwezonyango, amandla ahlaziyiweyo kunye nezisombululo ezihlaziyiweyo kunye namandla, kunye neetekhnoloji zedijithali, ulwakhiwo kunye nezothutho.

Yintoni i-D4, D5 kunye ne-D6 kwaye zisetyenziswa phi?

I-octthylclostiloslosilosilosiloxiloxine (D4), i-D4), i-DEAMAMETYCCCHOXAXane (D5) isetyenziselwa ukwakhiwa, i-elektroniki, ubunjineli, i-cosmetics kunye nokhathalelo lomntu.

I-D4, D5 kwaye i-D6 isetyenziswa rhoqo njengezikhethe eziphakathi, okuthetha ukuba izinto zisetyenzisiwe kwinkqubo yokwenziwa kwemveliso kodwa zikhona njengokungcola kwinqanaba eliphantsi kwiimveliso zokuphela.

Ithetha ntoni i-SVHC?

I-SvHC imele "into ebaluleke kakhulu".

Ngubani owenza isigqibo se-SVHC?

Isigqibo sokuchonga i-D4, D5, D6 Njengoko i-SVHC yenziwa yiKomiti yamalungu e-ECO (i-MSC), eye yaqulunqa iingcali ze-EU zelungu kunye ne-ECH.

Amalungu e-MSC acelwe ukuba aphonononge iidesisi zobugcisa ezingeniswe yiJamani ye-D4 ne-D5, kunye ne-ECO ye-D6, kunye nezimvo ezifunyenwe ngexesha lokubonisana noluntu.

Igunya lale ngcali kukuvavanya kwaye liqinisekise ngesizathu lesayensi ingenzi izindululo ze-SVHC, kwaye zingavavangeli ifuthe elinokubakho.

Kutheni i-D4 yayidweliswe yi-SVHC?

Ngokusekwe kwiikhrayitheriya ezisetyenzisiweyo ukufikelela, i-D4 ihlangabezana neenqobo zokuziphatha eziqhubekayo, ezinobungozi kwaye ezinetyhefu (PBT) zetyhefu (PBT), kunye ne-D5 kunye ne-D6 zihlangabezane neenqobo zokuziphatha ezifanelekileyo.

Ukongeza, i-D5 ne-D6 ithathelwa ingqalelo i-PBT xa iqulethe ngaphezulu kwe-0.1% D4.

Oku kukhokelele ekutyunjweni kwe-EU yamalungu e-EU kuluhlu lwee-SVCS. Nangona kunjalo, siyakholelwa ukuba iikhrayitheriya azivumeli uluhlu olupheleleyo lobungqina obuchaphazelekayo besayensi ukuba buqwalaselwe.
