Search for irritating compounds in RJ45 cords

This involves looking for and quantifying potentially irritating molecules* using different analysis techniques on a pallet of boxes of RJ45 cords from a country outside the EU. Indeed, during the handling of the inconveniences alerted the health services.

*Irritant compound (nm): defined by a non-corrosive substance or preparation which, through immediate, prolonged or repeated contact with the skin or mucous membranes, can cause an inflammatory reaction.

Analytical protocol:

The various possibly irritating molecules will be analyzed according to their nature (organic, ionic, etc. ) and their volatility:

Analysis by HS-GCMS will allow the identification of ultra-volatile organic molecules present in the sample (COUV <350 g / mol).
Analysis by GCMS will allow the identification of volatile organic molecules present in the sample (VOC - 100 <Mw <620 g / mol).
Analysis by UPLC/TOF-MS will allow the identification of semi-volatile and ionic organic molecules present in the sample (100 <Mw <2500 g / mol).

→ The analyzes carried out on all the parts of the sample (bead, PE bag, cardboard, film) mainly show compounds of the Adjuvants for polymers type (plasticizers, slip agents, etc.) as well as more volatile degradation products such as Nonanal [124-19-6] present in large quantities and which could be the source of annoyance such as irritation.

Identified compound	CAS number	Chemical family	Sample content (ppm)	identification of risks
Nonanal	124-19-6	Aldehyde	125	H226 Flammable liquid and vapor H315 Causes skin irritation H319 Causes serious eye irritation.
