Description of key information

non flammable on ignition (EU A.10) 
no pyrophoricity
no flammability on contact with water

Key value for chemical safety assessment

Additional information

According to the manufacturer's experience, and available experimental evidence on a variety of alkyl sulfates, solid forms of bulk density < 400 g/L are flammable on ignition, whereas solid forms of higher bulk density > 400 g/L are non-flammable. In terms of aggregate state, this corresponds approximately to powders and granulates, respectively.

Based on experience in handling and use and the chemical structure, pyrophoricity and flammability on contact with water are not to be expected.

Justification for classification or non-classification

According to Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures, the dry substance, characterized by bulk density < 400 g/L, is considered to be a flammable solid, Category 1 (H228). However, the substance is marketed only in the high water content states (paste or aqueous solution), and no risk of flammability is expected.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
