non flammable no pyrophoricityno flammability on contact with water
The dried substance is non-flammable as determined in the test according
to UN Method N.1. The substance is marketed solely in the high water
content states (aqueous solutions). 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. The substance is not self-heating, since the melting point is
below 160 °C.
According to Regulation (EC) No 1272/2008 on classification,
labelling and packaging (CLP) of substances and mixtures, the substance,
characterized by bulk density < 400 g/L, is considered to be a flammable
solid, Category 1 (H228), and as R11 according to Directive 67/548/EEC.
However, the substance is marketed in the high water content states
(aqueous solutions), and in this case, no risk of flammability is
Based on the chemical structure and experience in handling and use,
pyrophoricity and flammability on contact with water are not expected.
Based on the fact that the melting point is < 160 °C, the substance is
