Glicerina 98.0-101.0% (by alkalimetry) ACS, Reag. Ph. Eur.
Fornitore: Merck
Synonyms:
1,2,3-Propanetriol, Propane-1,2,3-triol, Glycerol
M-Clarity™ quality level = MQ300
Bio-Based Glycerol
Our bio-based glycerol is produced from rapeseed, a renewable raw material, and a by-product of biodiesel production. It offers numerous advantages compared to petroleum-derived glycerol.
- Non-toxic, nonirritating
- Nonflammable (flash point 160 °C, autoflammability 400 °C)
- No waste due to 100% biodegradability
- Low vapor pressure (environmental advantage)
- Reliable availability (independent of petrochemical production)
