The main use of glycerine (also known as glycerol) is as a humectant, meaning it's primarily used to retain moisture.
Glycerine as a Humectant
Glycerine's ability to absorb water from the air makes it an extremely effective moisturizer. This property is crucial in many applications:
- Skincare Products: Glycerine is widely used in lotions, creams, and soaps to keep skin hydrated. A 2017 study highlighted its effectiveness as a skin moisturizer.
- Pharmaceuticals: It's used in medications to maintain moisture and prevent dryness.
- Food Industry: Glycerine acts as a humectant to preserve the moisture content of baked goods, candies, and other food products.
Why is Glycerine a Good Humectant?
- Water Absorption: It readily absorbs water from the air, drawing moisture to the surface it's applied to.
- Skin Benefits: Beyond moisturizing, glycerine can help improve skin barrier function and protect against irritants.
- Versatility: Its properties make it suitable for a wide range of applications across different industries.
In summary, while glycerine has several uses, its primary function is as a humectant, keeping things moist and hydrated, especially in skincare, pharmaceuticals, and food.
