Musi waChivabvu 17, 2024, iyo Official Journal yeEuropean Union (EU) yakaburitswa (EU) 2024/1328, ichidzokorodza chinhu makumi manomwe chezvakarambidzwa zvinhu zvinyorwa muAnnex XVII yeREACH mutemo kurambidza octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D) , uye dodecylhexasiloxane (D6) muzvinhu kana musanganiswa. Mamiriro matsva ekushambadzira ekusuka zvizorwa zvine D6 uye zvizorwa zvekugara zvine D4, D5, uye D6 zvichatanga muna Chikumi 6, 2024.

Zvinoenderana nemutemo weREACH wakapasiswa muna 2006, iyo mirairo mitsva inorambidza zvakanyanya kushandiswa kweanotevera matatu emakemikari zvinhu mune zvisiri gonococcal cosmetics uye zvimwe zvevatengi uye zvehunyanzvi zvigadzirwa.

5. Sekuregererwa, pfungwa (b) yendima 1 haishande kuD4, D5, uye D6 yakaiswa pamusika: - sezvikamu zve organosilicon polymers - sezvikamu zve organosilicon polymers mumisanganiswa inotsanangurwa mundima 6.

6. Sekuregererwa, poindi (c) yendima 1 haishande kumisanganiswa ine D4, D5, kana D6 sezvisaririra zve organosilicon mapolima akaiswa pamusika pasi pemamiriro anotevera:

(a) Mushonga weD4, D5 kana D6 wakaenzana kana kuti pasi pe1% yehuremu hwechinhu chinoenderana mumusanganiswa, unoshandiswa pakubatanidza, kuisa chisimbiso, gluing uye kukanda;

(b) Musanganiswa wezvidziviriro zvekudzivirira (kusanganisira zvikepe zvezvikepe) nehuwandu hweD4 yakaenzana kana kuti pasi pe0.5% nekurema, kana kusanganiswa kweD5 kana D6 yakaenzana kana pasi pe0.3% nekurema;

(c) Iko kusanganiswa kweD4, D5 kana D6 yakaenzana kana kuti isingasviki 0.2% yehuremu hwechinhu chinoenderana mumusanganiswa, uye inoshandiswa semidziyo (yekurapa) sezvinotsanangurwa muChikamu 1 (4) cheMutemo (EU). ) 2017/745 uye Chinyorwa 1 (2) cheMutemo (EU) 2017/746, kunze kwemidziyo yakataurwa mundima 6 (d);

(d) D5 kusungirirwa kwakaenzana kana kushoma pane 0.3% nehuremu hwemusanganiswa kana D6 yekumisikidza yakaenzana kana isingasviki 1% nehuremu hwemusanganiswa, unoshandiswa sechiridzwa chinotsanangurwa muChinyorwa 1 (4) cheMutemo (EU) 2017. /745 nokuda kwezviratidzo zvemazino;

(e) Iko kusanganiswa kweD4 mumusanganiswa kwakaenzana kana kuderera kune 0.2% nehuremu, kana kuwanda kweD5 kana D6 mune chero chinhu chiri musanganiswa yakaenzana kana isingasviki 1% nehuremu, inoshandiswa sesilicon insoles kana shangu dzemabhiza;

Pfupiso:

Nekuda kweD4, D5, uye D6 zviri zvinhu zvine chekuita nepamusoro (SVHC), zvinoratidza kushingirira uye kuunganidza bioacumulation (vPvB). D4 inozivikanwawo seinoramba iripo, bioaccumulative, uye muchetura (PBT), uye kana D5 neD6 dzine 0.1% kana kupfuura dzeD4, dzinozivikanwawo sedzine PBT maitiro. Tichifunga kuti njodzi dzePBT uye vPvB zvigadzirwa hazvina kudzorwa zvizere, zvirambidzo ndiyo yakanyanya kukodzera manejimendi chiyero.

Mushure mekudziviswa uye kutonga kwekusuka zvigadzirwa zvine D4.D5 uye D6, kutonga kwezvinhu zvisiri zvekusuka zvine D4.D5 uye D6 zvichasimbiswa. Panguva imwecheteyo, tichifunga nezvezvino zvakakura zvekushandiswa kwemamiriro ezvinhu, zvirambidzo pakushandiswa kweD5 mumachira, matehwe, uye fur dry cleaning, pamwe nekurambidzwa kushandiswa kweD4.D5 uye D6 mumishonga nemishonga yemhuka, ichamiswa. .

Zvichipa kushandiswa kukuru kweD4.D5 uye D6 mukugadzirwa kwepolydimethylsiloxane, hapana zvipingamupinyi zvakakodzera pane izvi zvinoshandiswa. Panguva imwecheteyo, kuitira kujekesa musanganiswa wepolysiloxane une zvisaririra zveD4, D5, uye D6, miganho yekutarisa inoenderana yakapihwawo mumasanganiswa akasiyana. Makambani akakodzera anofanirwa kuverenga nekunyatso verenga zviga zvakafanira kudzivirira kuti chigadzirwa chive pasi pezvisungo zvinorambidza.

Pakazara, izvo zvinorambidzwa paD4.D5 uye D6 zvine zvishoma zvinokanganisa indasitiri yemumba silicone. Makambani anogona kusangana nezvakawanda zvezvirambidzo nekufunga nezve zvakasara zveD4.D5 uye D6.

BTF Testing Lab, kambani yedu ine electromagnetic inoenderana marabhoritari, kuchengetedza mirau Laboratory, isina waya radio frequency Laboratory, bhatiri Laboratory, Chemical Laboratory, SAR Laboratory, HAC Laboratory, nezvimwewo. VCCI, nezvimwewo Kana iwe uine yakakodzera kuyedzwa uye zvitupa zvinodiwa, unogona kubata zvakananga vashandi vedu Vekuyedza kuti uwane yakadzama mutengo makotesheni uye kutenderera ruzivo!
