How Does Propylene Glycol Compare to Ethylene Glycol?
Propylene glycol is often compared to ethylene glycol due to their similar uses, especially in antifreeze products. However, ethylene glycol is significantly more toxic than propylene glycol. Ethylene glycol ingestion can lead to severe metabolic acidosis, renal failure, and neurological damage. Propylene glycol, by contrast, exhibits a much lower toxicity profile, making it a safer alternative for many applications.
