Propylene glycol has low toxicity and irritation, but it has hemolytic properties and is not suitable for intravenous injection.

When it is added to food and beverages, like ethylene glycol, it has the risk of causing kidney disease. Therefore, some countries have banned its use in food industry.

In cosmetics, toothpaste and soap, propylene glycol can be used as a wetting agent in combination with glycerin or sorbitol.

Triethanolamine has the lowest oral toxicity among amines. As long as the dosage and usage are proper, it is harmless to the human body.
