Butylene Glycol
What is Butylene Glycol?
Butylene Glycol is a synthetic alcohol derived from petroleum and is commonly used in cosmetic products. It is a clear, colorless liquid that acts as a humectant, helping to retain moisture in the skin.
In skin care and beauty products, Butylene Glycol is used to improve texture, acting as a solvent to thin formulations and enhance the penetration of other ingredients. The health evidence generally supports its safety, though some individuals may experience minor skin irritation.
When you see Butylene Glycol on a label, it is typically there to improve the sensory feel and effectiveness of the product by enhancing moisture retention.
Commonly found in: Deodorant, Skin Care, Makeup, Moisturizers, Lotions
