Secondly, is propylene glycol bad? The toxicity of propylene glycol is very low. It has not been found to cause cancer, damage genes or interfere with fertility or reproduction. Moreover, there are no reported deaths on record ( 1 , 9 ).

In this manner, what happens to propylene glycol when heated?

Propylene glycol at high levels causes irritation if inhaled [2]. This occurs because of propylene glycol and glycerol is heated using oxygen [10]. When propylene glycol is heated it may change the chemical composition and produce propylene oxide in a little amount which is known as carcinogen [11].

What are the side effects of propylene glycol?

Toxicity and side effects The propylene glycol formulation can cause tissue trauma and long-term damage to veins. Drug-induced reactions include fever on first administration, abdominal colic pain, dermatitis and arthralgia. Polyneuropathy has been reported in about 10% of patients.
