Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

The DNELs for local inhalation effects are based on the corresponding DNELs that are available for hydrogen peroxide, taking into account that:

a) according to the stoichiometry of the hydrolysis reaction of magnesium peroxide, an equimolar amount of hydrogen peroxide is formed; and that

b) the reaction mass of magnesium carbonate and magnesium hydroxide and magnesium oxide and magnesium peroxide typically contains 37% of magnesium peroxide.

 

Worker – inhalation – local effects – long term

 

DNEL (hydrogen peroxide):                      1.4 mg/m3

 

a) stoichiometrie

 

1.4 mg hydrogen peroxide                        = 4.116E-05 mol hydrogen peroxide

= 4.116E-05 mol magnesium peroxide

 

4.116E-05 mol magnesium peroxide          = 2.3 mg magnesium peroxide

 

DNEL (magnesium peroxide)                    = 2.3 mg/m3

 

b) composition of reaction mass

 

DNEL (magnesium peroxide)                    = 2.3 mg/m3

DNEL (reaction mass)                             = 6.2 mg/m3

 

The worker long-term DNEL for local effects following inhalation of the reaction mass of magnesium carbonate and magnesium hydroxide and magnesium oxide and magnesium peroxide is:

 

DNEL (reaction mass)                             = 6.2 mg/m3

 

 

Worker – inhalation – local effects – short term

 

DNEL (hydrogen peroxide):                      3.0 mg/m3

 

a) stoichiometrie

 

3.0 mg hydrogen peroxide                        = 8.821E-05 mol hydrogen peroxide

= 8.821E-05 mol magnesium peroxide

 

8.821E-05 mol magnesium peroxide          = 5.00 mg magnesium peroxide

 

DNEL (magnesium peroxide)                    = 5.00 mg/m3

 

b) composition of reaction mass

 

DNEL (magnesium peroxide)                    = 5.00 mg/m3

DNEL (reaction mass)                             = 13.4 mg/m3

 

The worker short-term DNEL for local effects following inhalation of the reaction mass of magnesium carbonate and magnesium hydroxide and magnesium oxide and magnesium peroxide therefore is:

 

DNEL (reaction mass)                             = 13.4 mg/m3
