Description of key information

According to Annex X of REACH Regulation 1907/2006, this study does not need to be conducted if the available data on mammalian species show no significant effect. In the section 6 of IUCLID it is shown that Magnesium hydroxide does not meet the criteria to be classified as dangerous under the CLP Regulation (EC) No 1272/2008 nor does it meet the criteria to be classified as persistent, bioaccumulative or toxic under the REACH Regulation. Magnesium hydroxide is expected to break down in the environment to water and Magnesium over time. Magnesium is ubiquitous in the environment and is an essential plant and animal nutrient. Taking into consideration the physico-chemical properties, available studies wth mammalian species, breakdown pathway and the low adsorption to sediment, Magnesium hydroxide is not considered to pose a risk to birds.
