Propylene Glycol in Skin Care: Benefits and Safety
A Closer Look at a Versatile Ingredient
What is Propylene Glycol?
Propylene glycol is a synthetic ingredient commonly used in skincare products as a humectant, emollient, and preservative. It helps retain moisture, soften skin, and inhibit microbial growth, extending product shelf life.
Benefits of Propylene Glycol in Skin Care
1. Extended Shelf Life: Propylene glycol's antimicrobial properties help products resist spoilage, allowing for longer shelf lives without the need for harsh preservatives.
2. Hydration: As a humectant, it draws moisture from the environment and retains it in the skin, keeping it hydrated and supple.
3. Skin Softening: Its emollient properties help soften and smooth rough skin, reducing flakiness and dryness.
Safety of Propylene Glycol
Propylene glycol is generally considered safe for cosmetic use by regulatory bodies, including the Expert Panel for Cosmetic Ingredient Safety (2012).
- Non-Carcinogenic: It is not classified as a carcinogen or associated with any increased risk of cancer.
- Non-Endocrine Disrupter: It does not interfere with the body's hormonal system.
