Description of key information

- SCP liquor is considered to be incapable of reacting exothermically with combustible material (4.13) and classification is not required. 
- Data waiving is based on the rules in Column 2 of Annex VII (7.13) stating that no test is required if the substance cannot react exothermically with combustible materials e.g. according to its chemical structure.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Data waiving is based on the rules in Column 2 of Annex VII (7.13) in the REACH regulation stating that no test is required if the substance cannot react exothermically with combustible materials e.g. according to its chemical structure.

SCP liquor is a UVCB substance consisting of variable organic and inorganic compounds from cellulosic raw materials and process chemicals. The main organic components are cellulosic lignin, polysaccharides and aliphatic carboxylic acids, and the main inorganic components are sodium carbonate, sodium sulfate, sodium sulfite and sodium thiosulfate. The known structures do not suggest SCP liquor to present a danger of oxidation and to increase the burning rate or burning intensity of a combustible substance, or to form a mixture with a combustible substance which would spontaneously ingnite under the conditions described in the test guideline A.21 (EC 440/2008). Therefore no test for oxidising properties of SCP liquor is considered necessary.

Justification for classification or non-classification

SCP liquor is considered to be incapable of reacting exothermically with combustible material based on the evaluation of the prperties of its main ingredients, and classification is not required.

Data waiving is based on the rules in Column 2 of Annex VII (7.13) in the REACH regulation stating that no test is not required if the substance cannot react exothermically with combustible materials e.g. according to its chemical structure.
