Glycerin is a low-toxicity, low-irritant chemical and is widely considered generally recognized as safe (GRAS).
It is essentially non-irritating to skin and eyes and is widely used in cosmetics, food, and pharmaceuticals.
Key Safety Considerations
Non-toxic, non-flammable (may decompose upon heating at high concentrations)
Easily non-irritating to skin and eyes
Extremely low risk of inhalation (extremely low vapor pressure)
Large doses may cause mild stomach upset
Heating decomposes it, producing irritating fumes; avoid high temperatures (>180°C)
Personal Protective Equipment Recommendations
No special protection is required for general handling.
For large-scale industrial use, the following are recommended:
Protective gloves
Safety goggles
Well-ventilated environment
