Description of key information
- White liquor is likely to be corrosive to metals and classification is required.
- The classification concerning corrosivity is assigned based on information from the manufacturers of White liquor and the supporting study.
Additional information
White liquor is likely to be corrosive to metals and classification is required. The classification concerning corrosivity is assigned based on information from the manufacturers of White liquor.
It is stated in the CLP guidance (section 2.15.3.2, Screening procedures and waiving of tests) that experience may have proven the corrosivity of given substances and mixtures. In such case no more testing is needed.
By the study of Crowe & Yeske (1987) there were dramatic increases in corrosion rates with thiosulfate additions, particularly in solutios with high sulfide concentrations. This result confirms the observation that liquors are more corrosive when high concentrations of Na2S and NaOH are present in mill liquor. Corrosion rates also increased with increasing NaOH concentration. The corrosion rate will be high where thiosulfate is formed by oxidation of sulfide, for example at the liquid/vapor line in pipes and tanks.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
