Propylene glycol in large doses can lead to liver, heart and nervous system disorders as it can damage human cells. Propylene glycol can even disrupt the body’s chemical balance, leading to excessive acid production that can cause metabolic problems. After prolonged contact with skin or eyes, it can cause irritation.
