Conclusion on classification

Talc (Mg3H2(SiO3)4) does not meet the criteria to be classified for environmental hazards. Based on the hazard assessment of Talc (Mg3H2(SiO3)4) section 2.1 and 2.2.in IUCLID 6., available data for the substance and following the “Guidance on Information Requirement and Chemical Safety Assessment R.10, it is concluded that none of the following phrases needs to be assigned according to the criteria described in Directive 67/548 and in the CLP Regulation:

 

Directive 67/548

N; R50

R52

R53

N;R50/53

N;R51/53

R52/53

N;R59

CLP Regulation

H400 Aquatic. Acute 1 Very toxic to aquatic life

H413 Aquatic Chronic 4 May cause long lasting harmful effects to aquatic life

H400 Aquatic acute 1, Very toxic to aquatic life

H410 Aquatic chronic 1 Very toxic to aquatic life with long lasting effects

H411 Aquatic Chronic 2 Toxic to aquatic life with long lasting effects

H412 Aquatic Chronic 3 Harmful to aquatic life with long lasting effects

EUH059 Ozone, Hazardous to the ozone layer

 

 

The substance has no potential to cause toxic effects if accumulated via the food chain in higher organisms.

Based on on reliable ecotoxicological studies which indicate that the substance is not acutely toxic and not classified.

Based on the hazard assessment of Talc (Mg3H2(SiO3)4) in section 2.1 and 2.2, in IUCLID 6., available data for the substance and following the “Guidance on Information Requirement and Chemical Safety Assessment R.16, Environmental exposure estimation”, it is concluded that none of the following symbol and phrases needs to be assigned according to the criteria described in Directive 67/548:T+, T, or Xn and the risk phrases R48, R60, R61, R62, R63, R64.
