Classification Propylene Glycol 2016


The German Member State has submitted a report to reclassify propylene glycol as a respiratory irritant (STOT SE3 under CLP): http://echa.europa.eu/documents/10162/13626/clh_propane-1%2C2-diol_en.pdf
The official proposed classification is: STOT SE3 - Specific Organ Target Toxicity after single exposure, hazard category 3, respiratory tract irritation. Associated with hazard statement 335 – “May cause respiratory irritation”.


Concerns about vaping safety seem once again to have motivated this CLH report.


Implications of STOT SE3 H335 labelling
PG itself as well as and any mixture (incl. eliquids) with 20% or more PG (assuming one uses the calculation method to decide on mixture classification) will have the following precautionary statements:

  • P261 - Avoid breathing dust/fume/gas/mist/vapours/spray
  • P271 – Use only outdoors or in a well ventilated area
  • P304 & P340 – If inhaled: Remove victim to fresh air and keep in a position comfortable for breathing
  • P312 – Call a poison centre or doctor/physician if you feel unwell.
  • P403 & P233 – Store in a well ventilated place. Keep container tightly closed
  • P405 – Store locked up.


This proposal is currently open for public comments till 21 April:
