General Information
- Implementation:
- EU
- Type of classification:
- self-classification
- Remarks:
White liquor is classified as Skin Corr. Cat. 1A based on a newly conducted GLP OECD guideline compliant study on
skin corrosion. The estimated maximal concentration of the typical component sodium hydroxide confirms the classification to skin corrosion,based on the harmonized classification of sodium hydroxide.
Acute toxicity studies do not generally need to be conducted if the substance is classified as corrosive to skin (REACH Regulation 1907/2006, Annex VII). The concentration of the typical toxic component disodium sulfide in White liquor reach the oral and dermal limit for acute toxicity classification of the substance and specific concentration limits have been givenbased on sulfide content.
The physico-chemical parameters that derive classification have not been newly tested for White liquor, which has been justified in the waivers with the comparative end-point summaries.
Aquatic acute toxicity of White liquor has been newly studied by GLP OECD guideline compliant test methods.The results suggest Aq. Acute Cat. 1 classification based on sulfide content. The substance is regarded readily degradable
in the aquatic environment, due to rapid (bio)degradability of sulfides. No classification to Aquatic chronic categories is required due to rapid degradation/transformation and lack of bioaccumulation.
The supplemental hazard information for White liquor is given due to liberation of toxic gas (hydrogen sulfide) in contactwith acids.
