What is Propylene Glycol?
Propylene Glycol is a synthetic liquid substance that absorbs water. It is mainly produced from petroleum products and is commonly used in the food, cosmetic, and pharmaceutical industries.
It's used as a solvent, humectant, and preservative, helping to retain moisture and dissolve active ingredients. The safety of propylene glycol is generally accepted, but some people can experience skin irritation or allergic reactions.
When you see Propylene Glycol on a label, it indicates its role as a moisture-retaining agent and solvent. The concentration and formulation type influence its effects and safety.
