The two main antifreezes additives are ethylene glycol and propylene glycol. Usually used in car engine as coolant and to avoid winter freezing, ethylene glycol has a freezing point of -12,9°C and propylene glycol -59°C. They are both biodegradables and they break down into carbon dioxide and water[1]. Ethylene glycol is hazardous for human and wildlife in case of ingestion [2]. On the contrary, propylene glycol has the same properties as ethylene glycol, but is recognized by the Food and Drug Administration (FDA) as generally safe. [3]
