Pigmenti

Pigmenti

Pigmenti so netopne organske ali neorganske kemikalije, ki se uporabljajo za obarvanje različnih izdelkov na trgu EU. Zajemajo številne kemikalije, med katerimi se nekatere uvrščajo med nanomateriale. Pri določanju lastnosti teh kemikalij ima lahko velikost pigmentnih delcev pomembno vlogo.

Nanomateriali, kot so denimo delci koloidnega zlata za barvanje vitražnega stekla, se uporabljajo že več sto let in jih lahko najdemo v vitražih številnih zgodovinskih objektov po vsej Evropi. Nanopigmenti so prisotni v najrazličnejših izdelkih, barvah, premazih, tiskarskih črnilih in kozmetičnih izdelkih.

Opredelitev meril za razvrstitev pigmentov med nanomateriale je velik znanstveni in regulatorni izziv, kar na splošno velja za vse nanomateriale. Dajanje pigmentov, vključno z nanopigmenti, na trg EU urejajo različni predpisi, vključno z uredbo REACH in, kjer je to ustrezno, tudi uredbe s področja kozmetičnih izdelkov in hrane.

 

Seznam nanopigmentov na trgu EU

V okviru študije, ki jo je naročil Observatorij Evropske unije za nanomateriale (EUON) z namenom proučiti varno uporabo nanopigmentov v potrošniških izdelkih ter njihovo varnost, kadar jih uporabljajo strokovnjaki in delavci, je bil pripravljen seznam nanopigmentov, ki so trenutno na trgu EU.

Seznam zajema 81 snovi iz podatkovne zbirke Evropske agencije za kemikalije (ECHA) ter snovi iz belgijskih in francoskih nacionalnih popisov kemičnih snovi ter iz kataloga Evropske unije o nanomaterialih v kozmetičnih izdelkih. Uporabljen je bil tudi danski register proizvodov. Za več informacij iz podatkovne zbirke ECHA o kemikalijah kliknite na ime snovi na seznamu.
