Interpretation of results:
GHS criteria not met
Conclusions:
According to testing and cited information, Guanidine hydrochloride is not to be classified as
flammable solid, pyrophoric solid, self-heating substance, substance, which, in contact with water, emit flammable gases
Executive summary:

Guanidine hydrochloride doesn't ignite

  • with a hot flame, with a glowing Platinium wire or in a glowing inron-cup
  • when applied on a hot surface (360 °C) or when blown as dust (0.5g) on a hot surface (600 °C)
  • on heating (up to 350 °C) in contact with air.

According to other supporting study, Guanidine hydrochloride (tested amount: 121 g) showed no exothermic reaction at heating on 173 °C over 92 hours.

According to water solubility information, Guanidine hydrochloride doesn't release flammable gases in contact with water.

According to testing (this and supporting IUCLID entries), Guanidine hydrochloride is not to be classified as

  • flammable solid
  • pyrophoric solid
  • self-heating substance
  • substance, which, in contact with water, emit flammable gases
